Rip and Convert FLAC, M4A, MP3, AAC files
I recently found an old harddisk which used to be in one of my old PC's. I discovered some FLAC files on there, which were rips of old CD's I used to have. iTunes is not too happy with importing them into my library, and the original CD's are in a box in a deep dark corner of my garage.
I searched for a converter and found this wonderful converter which can just about convert any audio format out there. It's called "Max", it's Open Source, free to use, and available as bundled OSX application. Brilliant! It does have a bunch of options, but as long as you go for the "MP4 Audio" output format, high quiality, 256 bits and VBR, you can't go wrong.
According to their website "Max can generate audio in over 20 compressed and uncompressed formats including MP3, Ogg Vorbis, FLAC, AAC, Apple Lossless, Monkey's Audio, WavPack, Speex, AIFF, and WAVE".
Happy transcoding!
