I have some FLAC files I want to convert to AAC, but I can't because my go-to program, Max, throws an exception (The call to ExtAudioFileSetProperty failed.) when it tries to convert 24-bit/96 kHz FLAC (16-bit is no problem) to any other format.

So is there another good program for converting from FLAC?


Personally I use a tool called X Lossless Decoder, or XLD for short. I use it for converting FLAC to Apple Lossless regularly, and it’s never hiccupped.

From the project’s page:

XLD can decode following formats:

  • (Ogg) FLAC (.flac/.oga)
  • […]


XLD supports various output formats. It can convert audio files into […] MPEG-4 AAC (QuickTime/CoreAudio), MP3 (LAME), Apple Lossless, FLAC […].

XLD is free, and is still being actively maintained. Highly recommended.

  • Just want to confirm that XLD can convert 24-bit/96 kHz FLAC without a hitch. – Dillon May 23 '14 at 14:52
