While converting audio files from *.m4a to *.wav using ffmpeg (and other audio converters - I've tried a few and cannot remember but they were worse) the file size increases by a lot (10x).
original file (Song01.m4a) 3,425KB
new file (Song01.wav) 38,057KB
Is this an issue specific to the software? Is this as issue dependent on the codecs converting from/to? What can is the best path to get the audio conversion smaller? (assuming I do not plan on converting back)
Additional context: Windows 10, Cygwin (mintty 1.1.3), ffmpeg version
