Both formats, briefly
AC3IN
AC3, sold as Dolby Digital, carries up to six channels in one stream: five full range plus a low frequency effects track. DVDs, Blu-rays and broadcast television settled on it, so home cinema receivers decode it in hardware. When an AC3 track plays as silence on a laptop or phone, converting it to stereo AAC or MP3 clears the problem.
M4AOUT
M4A is an MPEG-4 container holding audio and nothing else, nearly always AAC and occasionally Apple Lossless. It keeps chapter marks, artwork and bookmark positions, which is why audiobooks and podcasts lean on it as much as music does. When a player rejects an M4A, converting to MP3 is the usual fix.
