A wave file with the following info was not loading:

Format : PCM
Sample Rate : 44100
Bits Per Sample : 16
Channels : 2

After re-saving with Audacity (in same format), the file will import.

Turns out this was due to the way I was parsing RIFF wave files.

Per the specs I've read, PCM "fmt " chunks are not supposed to have "Extra Format Bytes" (see

I was expecting a 16 byte chunk, but this file had an 18 byte chunk.

Turns out I was reading the spec wrong (or not all programs respect the PCM clause- and include extra bytes).
