Maybe this :
$ file bunting.wav
bunting.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM,
16 bit, mono 44100 Hz
It works with wildcards.
And you can redirect the output.
$file *.* > mylist
The sfinfo utility is even better :
$ sfinfo bunting.wav
File Name bunting.wav
File Format Microsoft RIFF WAVE Format (wave)
Data Format 16-bit integer (2's complement, little endian)
Audio Data 4398656 bytes begins at offset 44 (2c hex)
1 channel, 2199328 frames
Sampling Rate 44100.00 Hz
Duration 49.871 seconds
Also works with wildcards and redirection.
