Remote mixing is the practice of mixing, processing, monitoring, or controlling audio from a location physically separate from the source of the audio or the venue in which a production is taking place. The term encompasses workflows used in live sound, broadcasting, recording, post-production, concerts, corporate events, houses of worship, sporting events, and other forms of live and recorded media production.

In a remote mixing system, an audio engineer may control a digital mixing console located at a venue through a network connection, receive individual or grouped audio channels at another location for mixing through a digital audio workstation (DAW), or use a combination of remote console control and transmitted audio. The resulting mix can be returned to the venue, incorporated into a television or radio broadcast, delivered to a livestream, recorded, or routed to another production system.

Remote mixing ranges from relatively simple remote control of an existing console to complex distributed-production systems in which the engineer, audio processing, performers, production staff, and audience may all be in different locations.

Although forms of remote audio production existed before the 2020s, adoption of remote workflows accelerated during the COVID-19 pandemic. Travel restrictions, social-distancing requirements, closures of studios and performance venues, and restrictions on public gatherings caused broadcasters, recording studios, churches, production companies, and live-event professionals to develop methods for performing production work away from the event site.

Technology and operation

Remote mixing does not refer to a single technology. It describes an audio-production architecture in which the engineer and some or all of the equipment being operated are geographically separated.

Three common approaches are remote console control, DAW-based remote mixing, and hybrid systems combining the two.

Remote console control

In remote console control, the primary audio processing remains on a digital mixing console or processing engine at the production location.

The remote engineer connects to the console through a network and controls parameters such as fader levels, preamplifier gain, equalization, compression, gates, effects, auxiliary sends, buses, matrices, mute groups, and signal routing.

The control connection itself generally carries data rather than the complete production audio. Moving a fader remotely, for example, sends an instruction to the console at the venue, where the corresponding audio-processing change occurs.

The engineer separately receives audio representing the production so that the effect of those changes can be monitored.

Depending on the system, monitoring may consist of a stereo program mix, individual channels, stems, buses, a solo or PAFL feed, or a complete multichannel audio stream.

Video monitoring is also frequently incorporated so that a remote engineer can see what is occurring on stage. Intercom, talkback, messaging, remote desktop access, and video conferencing may provide communication between the engineer and local production personnel.

Digital mixing consoles

The development of digital mixing consoles was an important prerequisite for widespread remote mixing.

On a traditional analog console, the physical controls form part of the signal path. Digital consoles instead convert audio into digital information and use physical controls to manipulate parameters within a digital processing system.

This separation between the control surface and processing engine made it possible for manufacturers to develop computer, tablet, and mobile applications capable of controlling a console over a local network.

Remote mixing extends this principle beyond the local network. Internet connectivity, virtual private networks, cloud-based control platforms, remote desktop applications, and manufacturer-specific systems can allow the control device and the digital console to be located in different buildings, cities, or countries.

One advantage of this architecture is that the audio processing can remain at the production site. The wide-area network may therefore only need to carry control information and sufficient audio and video for the remote engineer to monitor the production.

A 2021 live-production example involved Australian engineer Rich Bryant mixing the broadcast of the Passionate Women's Conference in Wellington, New Zealand, from Sydney, Australia, approximately 1,400 miles (2,300 km) away. The venue's Allen & Heath dLive processing system was controlled from a corresponding console in Sydney through a secure network connection, while separate low-latency systems provided audio and video monitoring.

DAW-based remote mixing

A second form of remote mixing uses a digital audio workstation as the primary mixing environment.

DAWs had already transformed recording and post-production by moving many functions traditionally performed by large-format mixing consoles and external hardware processors into software.

In a remote live-production workflow, individual audio channels may be routed from a venue's mixing console, audio interface, stage box, or networked audio system into a computer. The engineer can then use the DAW to create an independent mix.

Software processing may include channel strips, equalization, compression, limiting, gates, reverberation, delay, saturation, automation, metering, loudness processing, and other tools commonly associated with studio production.

The completed stereo or multichannel mix can then be routed to a streaming encoder, broadcast system, recording system, or back to the production venue.

This method can allow a live broadcast to use a substantially different processing environment from the sound-reinforcement system operating at the physical venue.

Hybrid systems

Remote console control and DAW-based mixing can be combined.

For example, an engineer may remotely control preamplifiers, routing, or other functions on the venue's digital console while receiving individual channels into a DAW to create a separate broadcast mix.

Other workflows may use a DAW primarily for additional processing while the actual summing and routing occur within a digital console.

Hybrid systems can divide responsibilities between local and remote engineers. A local engineer may control stage inputs, monitors, wireless systems, and other time-critical functions while a remote engineer creates a broadcast or livestream mix.

Latency

One of the primary technical challenges of remote mixing is latency, the delay between an event occurring at the production site and the engineer hearing or seeing it remotely.

Latency can be introduced by analog-to-digital conversion, digital buffering, audio encoding, video encoding, network transmission, internet routing, decoding, remote-control systems, and the streaming platform itself.

The amount of acceptable latency varies substantially according to the application.

A remote engineer creating a livestream or broadcast mix can often work with a modest delay because the program reaching the audience is itself delayed. In the 2021 Sydney-to-Wellington remote production, for example, the engineer received an audio and video broadcast feed with latency reported at under 150 milliseconds and a separate solo-monitoring feed at approximately 200 milliseconds.

Latency is considerably more problematic for musicians listening to themselves while performing. Consequently, stage monitors and in-ear monitors are generally mixed and processed locally even when another portion of the production is mixed remotely.

This division allows latency-sensitive audio to remain at the venue while less time-critical functions such as broadcast mixing can be performed elsewhere.

Applications

Television and sports broadcasting

Remote mixing is used within the broader field of remote production for television and sports.

In traditional outside broadcasting, substantial production equipment and personnel travel to the event location. Remote-production systems instead allow some production functions to occur at centralized facilities.

Audio and video from a stadium, arena, studio, or other venue can be transported over dedicated or public networks to another facility where directors, producers, replay operators, graphics operators, and audio engineers perform their respective roles.

Centralizing production can reduce the amount of equipment and personnel required at each venue and allow production resources to be shared between events.

In broadcasting, these workflows are frequently associated with the terms REMI and at-home production.

Concerts and live events

Remote mixing can be used for concerts, conferences, festivals, theatrical productions, and other live events.

The digital console or processing engine may remain at the venue while the engineer operates a corresponding control surface or software interface from another location.

The remote engineer typically receives an audio monitoring feed and a video representation of the event and communicates with technicians at the venue through an intercom or other communications system.

The ability to operate a production without traveling to the venue became particularly useful during COVID-19 travel restrictions.

Front-of-house sound

Remote technology can also be used to control front-of-house sound.

This application differs from broadcast mixing because a front-of-house engineer normally hears the loudspeaker system and acoustic environment directly.

A remote front-of-house engineer therefore requires a method of approximating the sound at the venue. This may involve reference microphones, room microphones, measurement systems, video monitoring, communication with local personnel, or a combination of these methods.

Because the engineer is not physically present, local personnel may still be required to handle microphones, stage connections, wireless systems, equipment failures, and other physical tasks.

Recording and music production

Remote mixing is widely applicable to recording and music production.

The simplest form does not occur in real time. Multitrack recordings can be transferred electronically to a mixing engineer working in another studio. The engineer completes a mix and sends it to the artist or producer for review.

More interactive systems allow artists, producers, engineers, and clients to participate in the session simultaneously from different locations.

High-quality audio streaming can provide a client with a substantially higher-fidelity representation of the DAW output than conventional video-conferencing audio, while video conferencing or talkback allows participants to communicate.

Remote studio workflows became particularly important when recording facilities were closed or restricted during the COVID-19 pandemic.

Film and television post-production

Remote audio workflows are also used in film and television post-production.

Sound editors, dialogue editors, sound designers, composers, re-recording mixers, directors, and producers may work from different locations while sharing synchronized audio and picture.

Remote review systems allow directors and producers to listen to work being performed at a mixing facility without being physically present.

More extensive systems allow the engineer or re-recording mixer to operate from a home or remote studio.

Corporate events and conferences

Remote mixing can be used for conferences, corporate meetings, product launches, educational events, and hybrid events.

These productions may combine presenters and audiences located at a physical venue with additional speakers, production personnel, and viewers participating through the internet.

Remote audio personnel can manage broadcast feeds, presentation audio, remote contributors, playback, and other program sources without occupying space at the physical event.

Livestreaming

Livestreaming is one of the principal applications of remote audio mixing.

A dedicated livestream mix is often preferable to simply sending the front-of-house mix to the internet because the acoustic environment experienced by an in-person audience is different from the signal received by an online audience.

A remote engineer can create a dedicated broadcast mix specifically for headphones, televisions, computers, and mobile devices while another engineer or volunteer concentrates on the physical venue.

Churches and houses of worship

Remote mixing has developed into a specialized application for houses of worship, particularly for church livestreams.

Many churches livestream worship services containing spoken word, music, congregational singing, video playback, and other program elements. Creating a consistent online audio mix can require skills similar to both live sound and broadcast music production.

The mix heard through a church's front-of-house system is not necessarily suitable for online distribution. An audience physically present in a room hears acoustic drums, guitar amplifiers, loudspeakers, stage sound, congregational singing, and room reverberation in addition to the sound produced by the PA system. An online listener hears only the signals incorporated into the broadcast.

Audio educators working with houses of worship reported a substantial shift in demand during the COVID-19 pandemic. Yamaha's guide to church livestream sound noted that before the pandemic, training questions primarily concerned sanctuary sound, while after lockdowns began in early 2020, questions shifted heavily toward improving livestream audio.

Churches responded through several approaches. Some created a separate broadcast mix on the existing front-of-house console. Others installed a second console or routed individual channels into a DAW to create an independent broadcast mix.

Remote mixing adds another possibility by allowing the engineer creating that mix to work outside the church facility.

The engineer may remotely control a dedicated broadcast console, control a mix bus on the church's primary console, receive multichannel audio into a DAW, or use a combination of these methods.

A video feed allows the engineer to follow the progression of the service while audio monitoring allows mixing decisions to be made in real time. Communication systems may connect the engineer with local volunteers or production staff.

The model can be particularly useful for churches that own appropriate production equipment but do not have an experienced broadcast engineer available locally.

By separating the location of the engineer from the church, an audio engineer can potentially serve congregations in different geographic regions without traveling to each location.

By the mid-2020s, dedicated technology platforms were being marketed for this application. BoxCast described remote audio mixing as a workflow gaining traction within modern church production and developed tools for controlling compatible digital consoles over the internet while providing audio and video monitoring.

History

Development before the COVID-19 pandemic

Remote audio production developed from several technologies rather than from a single invention.

Broadcast organizations had already developed centralized production systems in which personnel could work away from sporting events and other broadcasts. Digital mixing consoles made it possible to separate the control interface from the underlying audio-processing hardware.

At the same time, DAWs allowed professional audio processing to be performed entirely within computers, while broadband internet and Audio over IP technologies increased the amount and quality of audio that could be transported between locations.

Remote desktop software, virtual private networks, digital console applications, low-latency audio codecs, cloud computing, and internet video streaming further reduced the requirement that an engineer be physically located beside the equipment being operated.

COVID-19 pandemic

The COVID-19 pandemic became a major catalyst for remote production.

Beginning in early 2020, restrictions affected international and domestic travel, workplaces, recording studios, concerts, sporting events, conferences, theaters, and religious gatherings.

Production organizations consequently had to determine which roles genuinely required personnel to be physically present and which could be performed remotely.

Audio mixing was one of the production roles that could, in some circumstances, be separated from the event location.

Engineers developed workflows combining digital consoles, DAWs, remote-control software, VPNs, low-latency audio streams, video monitoring, and communications systems.

The pandemic therefore did not originate remote mixing. Instead, it accelerated the adoption of technologies that had previously been used more selectively and encouraged their application to new areas of live production.

Some of these workflows continued after restrictions ended because they could reduce travel, centralize specialized personnel, and allow organizations to hire engineers without geographic restrictions.

Growth of remote church mixing

Churches were particularly affected by the transition to remote and hybrid production.

Restrictions on large gatherings caused many congregations that had previously treated livestreaming as a secondary service—or had not livestreamed at all—to make online video one of their primary means of reaching congregants.

Yamaha's church-audio training material describes the dramatic change in church-production priorities following the 2020 lockdowns, including churches attempting to establish acceptable livestream production rapidly despite limited personnel and experience.

This created a particular audio problem. A church could have an experienced front-of-house volunteer or engineer and still lack someone capable of simultaneously creating a separate broadcast-quality mix.

The ability to remotely control digital equipment created a model in which the broadcast engineer no longer had to be a member of the local congregation or live near the church.

Hillside Sound

Hillside Sound is a Virginia-based audio-production company that developed an ongoing service model centered on real-time remote audio mixing for churches during the early 2020s.

The company states that it began providing remote church mixing services in 2020 and describes itself as "The Original Remote Livestream Mixing Company".

Unlike conventional remote technical support, in which a technician connects to a church's system to troubleshoot or configure equipment, Hillside Sound's model involves an audio engineer actively mixing the service while it is occurring.

A dedicated engineer can remotely connect to the church's production environment each week, monitor the service, and create or manage the livestream mix in real time. The company also provides remote front-of-house support.

The approach effectively separates the position of broadcast audio engineer from the physical church staff. Instead of requiring each congregation to recruit, train, or employ a local broadcast engineer, the mixing function can be provided remotely.

Hillside Sound publicly documented the model during its early development. In a 2023 post, founder Nick Rector stated that the company was serving dozens of churches each weekend through "remote, real-time livestream audio mixing".

Hillside Sound states that it has mixed more than 10,000 church services since 2020 and has served more than 500 churches.

The company also uses a dedicated-engineer model in which churches can work with an engineer on an ongoing weekly basis rather than using remote access solely for troubleshooting or one-time production support.

The growth of the model was followed by broader commercial development of remote church-mixing services and technology. Other companies now advertise live remote broadcast mixing for churches, while technology providers have introduced platforms specifically designed to allow engineers to control digital mixers through the internet while receiving synchronized audio and video monitoring.

Hillside Sound's description of itself as the original company dedicated to real-time remote church livestream mixing represents the company's account of its history. Establishing an absolute claim that it was the first company worldwide to commercially provide this service would require independent published sources specifically documenting that distinction.

Remote mixing as a service

The development of reliable remote-control and monitoring technology has also enabled remote mixing as a service, in which organizations contract an off-site engineer or production company rather than employing an engineer at the production location.

This model differs from conventional outsourced post-production because the engineer participates in the production while it is occurring.

Potential applications include recurring church services, corporate broadcasts, conferences, livestreams, concerts, multi-site organizations, and other productions in which the same technical functions occur regularly.

A remote engineer may work from a dedicated studio containing calibrated monitors, headphones, physical control surfaces, DAWs, communications systems, and video displays while connecting to one or more production sites.

The model can also allow production companies to organize engineers according to time zone, technical specialization, or availability rather than geographic proximity to the event.

Advantages

One of the principal advantages of remote mixing is the ability to separate the selection of an engineer from the geographic location of a production.

An organization can potentially employ an engineer with specialized broadcast, music, live-sound, or production experience even when that engineer lives in another region.

Remote production can also reduce travel requirements and associated costs.

Centralized facilities can provide engineers with a consistent monitoring environment rather than requiring a complete production workspace to be established at every event location.

For recurring productions such as weekly church services, remote mixing can allow the same engineer to work with the organization repeatedly, creating consistency while avoiding the requirement that the engineer travel to the venue.

Remote systems may also allow specialized personnel to assist local volunteers. Rather than replacing all on-site personnel, the remote engineer can handle technically demanding mixing functions while local staff perform tasks that require physical access to equipment.

Limitations

Remote mixing also introduces technical and operational limitations.

Network reliability

A remote system depends on network connectivity. Internet outages, packet loss, network congestion, firewall configuration, or failure of remote-access infrastructure can interrupt monitoring or control.

Professional implementations may therefore include local fallback configurations allowing a production to continue if the remote engineer loses connectivity.

Acoustic isolation from the venue

A remote engineer cannot directly hear the acoustic environment at the production site.

This is relatively unimportant when creating a broadcast-only mix because the engineer is attempting to hear what the online audience receives.

It is more significant when remotely controlling front-of-house sound. Room microphones, reference microphones, measurement systems, and communication with local personnel can provide information about the venue but do not completely reproduce the experience of physically standing in the room.

Physical intervention

A remote engineer cannot physically replace a cable, reposition a microphone, change a battery, troubleshoot a failed wireless transmitter, or repair equipment.

Remote production therefore generally continues to require some level of local technical support.

Latency

Audio and video delay can cause the remote engineer to react later than an engineer located at the venue. System design must account for the delay and keep latency-sensitive functions local where necessary.

Security

Providing remote control of production equipment introduces network-security considerations.

Systems may use encryption, authentication, VPNs, restricted user permissions, firewalls, and other security mechanisms to prevent unauthorized access.

Relationship to distributed production

Remote mixing is part of a broader transition toward distributed production in which the physical location of an event is increasingly independent from the location of the personnel producing its media.

Video switching, graphics, replay, audio mixing, captioning, encoding, communications, recording, and production management can potentially occur at separate locations while being coordinated through networked systems.

In broadcasting, this architecture is associated with REMI and at-home production. Similar concepts are increasingly used for internet livestreams, concerts, corporate events, educational institutions, and houses of worship.

Remote mixing therefore describes less a particular piece of equipment than a production architecture: the audio sources, processing equipment, engineer, production staff, and audience do not necessarily need to occupy the same physical location.
