I want to convert a lot of *.flac and some high bitrate *.mp3 files to *.m4a files. I want to use a fixed bitrate of 192kb (stereo) and want to keep the audiotags (except of, obviously, the tag "bitrate" - this sshould nbe set to the correct 192kb.).
I'm using 64-bit Maverick.
I tried about every program I could find.
Arista Transcoder, Handbrake, Transmageddon (fails, seems only video works)
ffmpeg (tried "-acodec libfaac -ab 192k -map_meta_data outfile.m4a:infile.mp3")
But either they don't transfer the tags or they don't offer any way to set the bitrate to fixed 192kb or the resulting file doesn't show the new bitrate in any audio program (for example: nautilus saying "bitrate" n.a.")!
