Talk:Chorus (audio effect)

Some of the info used to make this article was merged in from Chorus. You can take a look at the history of Chorus, some of which contribtued to this article (among others), at Talk:Refrain/Old history from Chorus.--Commander Keane 06:22, 15 January 2006 (UTC)

Removing External Link to sales page

I'm removing an external links to several companies selling products. In on case, the user has no name and has only ever made edits to link wikipedia pages to the company's product page. Lunchworthy (talk) 22:30, 19 March 2019 (UTC)

New sample

really great new example, thanks —The preceding unsigned comment was added by 128.211.227.37 (talk) 02:13, 16 April 2007 (UTC).

Pitch shifters

I removed the reference to pitch shifters. They have nothing to do with the chorus effect. This article is generally confused and should be rewritten in the same format as those about flangers and phasers etc.

This article is not like the flanger and phaser articles because the chorus effect isn't just a gadget for electric guitar. Orchestras and choirs have been arranged as they are for centuries to create the chorus effect. I agree with your change from pitch shifting to pitch modulation, though. Well done. --Trweiss (talk) 21:47, 25 March 2010 (UTC)

I don't know what has been removed, but a pitch shifter, too, can be used to produce a chorus effect: Just put it slightly out of tune. Pitch modulation is not necessary; e.g. piano or guitar string pairs don't modulate either. They only modulate the timbre (by natural interferences).

Piano

I don't think the piano is a good example of a non-chorus instrument. In the middle and upper registers a piano has typically 3 strings per note and an artist piano tuner will not tune those strings identically, precisely to provide a subtle mixed tuning effect - in the same way (though maybe not to the same degree) as the 12-string guitar's B and E strings. Out of the factory pianos are typically tuned not to "beat" at all but this can make the piano sound rather mechanical. NickS (talk) 12:30, 28 March 2008 (UTC)

Ah, I see it's the "additional" effect of delay being discussed. Ignore the above. NickS (talk) 10:32, 17 April 2008 (UTC)

on chorus method

There's a big error in the "Method" section of article. In regards to electronic/synthesizer method of constructing a chorus effect, this is not a true statement:

"To produce the effect, either naturally or in simulation, individual sounds with roughly the same timbre and nearly (but never exactly) the same pitch converge and are perceived as one."

The individual sounds can be of the same pitch. In essence, chorus is simply a delay or a group of delays with very short delay times. The pitches of the sounds that come from the delays are not necessarily different from the pitch of the original input sound. I also do not see why the "individual sounds" cannot be of different timbres. —Preceding unsigned comment added by 72.148.88.128 (talk) 11:54, 24 April 2008 (UTC)

It's actually more about slight pitch variations than delay, though both can play a role. You can achieve a chorus effect with just pitch variations, but if you are only using delay, then you have delay, not chorus. Similar timbres are necessary because that's what chorus is. A violin, trumpet, and xylophone can't be in chorus with one another because they don't sound anything alike. --Trweiss (talk) 21:42, 25 March 2010 (UTC)

I agree with Trweiss. Delay may play a role only when the original signal itself changes its pitch. E.g. if you play a bottleneck slide on a guitar upwards and put, say, a 100 ms delay on it, then the delay will, of course, replay a signal from the past that has been recorded when the bottleneck was placed a bit lower on the neck. If you mix that with the current bottleneck location, which is already bit higher on the neck, you'll get a nice chorus effect. But it works only if the orignal signal itself varies its pitch. A constant pitch won't produce any chorus effect -- neither with nor without delay. --Suaheli (talk) 07:44, 3 April 2010 (UTC)

The statement that the original signal source must have a varying pitch for multiple short delays to become a chorus effect is not true. Most chorus units use delay lines, the percieved pitch modulation actually comes from a modulation of the delay times themselves (basically the same as a flanger, the main difference between the two are delay times and how much feedback you have at hand). —Preceding unsigned comment added by 85.166.67.161 (talk) 04:44, 17 December 2010 (UTC)

Yes it is true varying pitch must be present to create the effect. Chorus units use a variable delay time to cause the pitch variations. Remember, chorus isn't just a footpedal you buy at Guitar Center. The effect has been used for centuries by having multiple players or singers perform at the same time. The footpedals are only simulating the effect electronically. Pitch variation is what the effect is. --64.81.149.67 (talk) 22:24, 24 January 2011 (UTC)

Perceived as one?

I do not think that a main quality of a chorus effect is to be "perceived as one." Quite the opposite, it could certainly be argued that the chorus effect allows one sound to be perceived as many.

In fact, most of this article is unsourced. This article is about the chorus effect, not about a chorus or the perception of how a chorus sounds. Again, I'd be completely open to the argument if it were sourced from a respected authority, but right now this is nothing more than a random opinion. — Preceding unsigned comment added by 73.81.124.68 (talk) 07:01, 18 March 2017 (UTC)

simplify first sentence?

Can someone put the first sentence into simpler terms? I'm guessing it means one (for example) singer sings but it sounds like two of that person. — Preceding unsigned comment added by 97.43.129.249 (talk) 20:44, 12 August 2017 (UTC)
