Hi People,
I am currently adding support for Sonic Foundry's 64 bit wave files to
libsndfile:
http://www.zip.com.au/~erikd/libsndfile/
This file format is used by the program ACID and usually comes with a w64
filename extension and if you do a hexdup of the first part of the file,
they look something like this:
00000000: 72 69 66 66 2E 91 CF 11 A5 D6 28 DB 04 C1 00 00 riff.... ..(.....
00000010: C8 F7 00 00 00 00 00 00 77 61 76 65 F3 AC D3 11 ........ wave....
00000020: 8C D1 00 C0 4F 8E DB 8A 66 6D 74 20 F3 AC D3 11 ....O... fmt ....
00000030: 8C D1 00 C0 4F 8E DB 8A 28 00 00 00 00 00 00 00 ....O... (.......
00000040: 01 00 02 00 44 AC 00 00 10 B1 02 00 04 00 10 00 ....D... ........
00000050: 64 61 74 61 F3 AC D3 11 8C D1 00 C0 4F 8E DB 8A data.... ....O...
I currently have one example of this file format and I need more. The single
file I have is a 16 bit stereo file. I need some more files and what I'm
looking for (if they are available) is as follows:
- a mono file of any bitwidth
- files containing more than 2 channels
- files containing 8, 24 or 32 bit PCM data
- files containing float or double data
- files containing looping and other information
- files containing encoded data (ie not PCM nor float/double)
If anybody wishes to help this Free Software project by supplying examples files
I would be very pleased to hear from them. Please don't email files to me without
asking first as I would like to prevent my mail box from overflowing with
multiple copies of the same file.
Regards,
Erik
