Cannot open WAV file in python using scipy.io.wavfile

I'm trying to work with WAV files using scipy.io.wavfile but the file I want to read has headers inside of it (NIST). I tried deleting the headers (that was dumb), I tried using other libraries (wave), custom functions found online but It still doesn't work. I get "Not a WAV file."

The .wav files are from mocha-timit, a speech training corpus.

can someone help me out?

Thanks.

Solution

  • Some things you could try:

    (1) Use scikits.audiolab as in this question

    (2) Convert the wav format from NIST format to the standard RIFF format with a tool like sndfile-convert from 'libsndfile' (You'll need to change the original file endings to .nist).

    I got (2) to work on my own system and could read the files with scipy.io.wavfile.read
