Hello,

I am programming a music player for uncompressed 32 bit 7.1 (8 channels) PCM sounds, contained in WAV files.

I would need some test files, where to download such files?
Only free and legal downloads please.

Thanks, regards

what you want tested? you could synth the wav mux yourself. what's the container?

struct block{ int/float fl,fr,c,lfe,bl,br,ml.mr }

not?

I just need some WAV (container) files encoded as above specified (High Definition Audio).

Basically I need to test my application, so for example:
- if / how a sound is played
- channels allocation
- ... and so on

I guess repositories for such files exist, or?

you're making a music player for files that don't exist? and i thought i had a useless hobby.

32 bit integer PCM audio? In which system or application is such a thing used? Or maybe you mean 32 bit float? That's a quite common thing. Ask that on any audio recording studio oriented site.

Well, I managed to find some example files, see Multi-Channel Examples
http://www-mmsp.ece.mcgill.ca/documents/AudioFormats/WAVE/Samples.html

As far as I know, that audio format, should be used in common media like DVDs (5.1) and Blu-ray discs (7.1).

Normally only 24 bit (in a 32 bit wide "container") are used.

Just extract 7.1 DTS files from your favorite Blu-ray. You will have to thunk them to 32-bit because the sources before compression are 24-bit.

In the 1990s there were some attempts at standardized audio corpii, but none of them would help you as they were all 2.0 stereo, band-limited, or both. Most people nowadays just make their own based on the domain they're working in.
