The DACS in most decent smart phones are perfectly good to give a good rendering of uncompressed music - and decent headphones such as BOSE / Sennheiser etc even on blue tooth will be more than satisfactory.īTW if you can still find a copy of Winamp on Android it will actually play mp4a (always assuming the smartphones hardware can handle it). Some music apps on phones won't always play m4a files but they all will generally play FLAC - and with decent capacity micro sdhc cards and a proper set of headphones there's no reason to have horribly compressed mp3 music - I'd recommend if you must use mp3 stick to 320 kbs or at the very least 256 kbs.

If you have either a Linux system or a Windows system with BASH installed on it then the job is simply done with the following script.įor f in *.m4a do ffmpeg -i "$f" -c:a flac "$.flac" doneįor Ubuntu users - (physical or VM's) you might get a message saying ffmpeg is deprecated -that's not actually true -just download the current version.
