.m4a support

Working with the VoxCeleb2 Dataset which encodes audio in the m4a format I’ve not been able to use the library to load the files.

formats: no handler for file extension `m4a'
Segmentation fault (core dumped)

I tried using ffpemg to convert to a aac file ffmpeg -i in.m4a -c:a copy out.aac and got the same error

A script to do this for all files in the directory recursively

#!/bin/bash
  
for i in $(find . -type f); do
    ext="${i##*.}"
    if [[ $ext = m4a ]]
    then
        p=${i%".m4a"}
        echo $i 
        ffmpeg -v 0  -i $i $p'.wav' </dev/null > /dev/null 2>&1 &
    fi
done

At the moment you need to convert them to WAV, e.g.

ffmpeg -i in.m4a out.wav
