I run Cool Edit Pro 2000 as my recording software with a 24bit/96KHz M-Audio 2496 Audiophile sound card.
The purpose of my recording is archival of my out-of-print LPs, so I'd rather keep all the data I've recorded and cut the files down to 16/44KHz as a separate step for MP3s, etc...
I saving my files, I noticed that there were five formats capable of storing 24bit/96KHz data:
- 32-bit IEEE Float (0.24)
- 32-bit IEEE Float (16.8)
- 32-bit IEEE Float (24.0)
- 24-bit packed Intel PCM
- 24-bit packed Motorola PCM
Each format also had an addition parameter specifying a 0, +1, +2 or +3 offset for the input data (presumably for header information or other meta-data).
Without knowing anything about these formats, I see little point in the 32-bit formats as they would appear to waste 8-bits per sample (which, at 9600KHz can be significant).
Does anyone know these formats well enough to describe what the intent was for each and which of these, if any, stands out as the preferred format and offset for archival purposes?
Thanks in advance for the help,
AJ
