Thanks for the detailed steps.
It will be fixed, the WAV files contains some sort of metadatas (there is a LIST chunk), it's now skipped.

Hi,
It should be supported.
Do you have any errors? Can you share a sample file?
Note that 44.1 KHz samplerate is not supported.

Pardon me for the late reply, please let me share the sample file and also the detail in here:

  1. There's a test .wav file "stereo.wav" which is stereo (from https://www.youtube.com/watch?v=wVrC-XQ9Crg).
  2. Use ffmpeg to convert it from stereo to mono with the following command: $ ffmpeg -i stereo.wav -ac 1 mono.wav
  3. Use elc3 for encoding the mono.wav: $./elc3 -b 80000 -m 10 -r 48000 mono.wav mono.bin
  4. The error message shows "Bad or unsupported WAVE input file: Invalid argument"

Please let me attach both stereo.wav and mono.wav in the below:
wav_samples.zip
