Clarify 'cracked' edit

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)Reply

any further specs known? edit

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)Reply
