Talk:ACT (audio format)

Clarify 'cracked'

Odd word position. Is it cracked as in broken, i.e. not robustly coded, or does the output sound cracked or has it been hacked, i.e. reverse engineered? -- Regregex (talk) 17:37, 26 April 2009 (UTC)

any further specs known?

Does anyone have any further info on this format? I'm wondering about a way to convert it other than with the normal tools. 8000 bit/s is pretty low for ADPCM; either it's used some proprietary and likely very nasty-sounding 1-bit variety at 8khz (which almost nothing will be able to translate and is probably closer to CELP or GSM in arrangement), or a standard but poorly supported 2-bit at a barely-adequate 4khz (maybe a better compromise). I know that the old CoolEdit program can read 2-bit ADPCM, so maybe its derivatives or anything that uses the same codec could also translate the files? If so it would be relatively trivial to make a standalone or reusable library decoder or even encoder (if you were feeling crazy!) 193.63.174.10 (talk) 09:23, 29 October 2010 (UTC)
