Maybe this :

     $ file bunting.wav
     bunting.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 
16 bit, mono 44100 Hz

It works with wildcards.

     $file *.*

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.
