X Lossless Decoder (XLD) is a tool for OS X that is able to decode/convert/play various 'lossless' audio files. The supported audio files can be split into some tracks with cue sheet when decoding.

XLD supports the following formats:

  • (Ogg) FLAC (.flac/.ogg)
  • Monkey's Audio (.ape)
  • Wavpack (.wv)
  • TTA (.tta)
  • Apple Lossless (.m4a) [10.4 and later]
  • TAK (.tak) [Requires Wine]
  • Shorten (.shn) [SHN v3 only]
  • AIFF, WAV, etc.
Other formats supported by Libsndfile are also decodable. XLD uses not decoder frontend but library to decode, so no more...

What's New

Version 20140504:
  • AIFF/WAV/PCM output has now internal samplerate converter powered by libsoxr
  • Fixed a bug that caused noise with some .caf files
  • More tweaks on the ALAC compatibility issue


OS X 10.4 or later

Excellent piece of software that I'd happily pay for. The interface isn't incredibly intuitive but once you get the hang of things it works a treat and is lightning fast.

I've only used it to convert FLAC to M4A but, after more...

I want to backup my CDs in the best possible quality. I could not get this program running. Whatever CD I am using, the program stops working when ripping between two tracks showing an ever turning beachball. I can only stop the program with a force quit. The CD drive is then blocked an can only be reactivated by a restart of the machine. In its current version this program not useful for me.

Still the best audio converter out there. Better than superfluous app xACT.

Powerful audio converter that just does what it advertises.
One thing I do not like is the workflow/GUI.
It for sure not straight forward to use and makes me think the dev was on a high when creating this. :)

But as said, it works great ones you get the hang of it.

Probably more like he's just a developer not a UI designer.

Best free audio converter available. Period.

I used to use Max for my flac/wav/alac conversions, but I find XLD to do more of what I wanted. Drag and drop simple design and rock solid for the last ½ year for me. I also use Kid3 to tweak the tags/cover and disc counts if needed. My hats off to all you guys that code and provide useful donation/freeware that I could *never* create. Donations sent out again today to show my continued appreciation of all the fine work!

I've been using this tool as my transcoder for quite some time. The ease of use, stability and speed are superb.
I usually convert from FLAC to ALAC, so I just drop a folder with some FLAC's and a nice album art (as folder.jpg or cover.jpg in said folder) on the XLD app in the dock. After some quick edits of metadata, I'm all set.
Highly recommended, don't forget it's donationware: it's worth it! :)

Best app ever for converting/transcoding audio. It blows Max/xACT etc out of the water.

Have used Max successfully for years. However I came across a 24 bit FLAC that it couldn't handle. In trying XLD I was astonished at the speed converting to AAC for iOS play. Sound turned out great.

I downloaded because it is the only app that can split mp3 files (or flac,ape etc) with cue info files.

Tested it on Mavericks 10.9.2 to split an mp3 with its cue file.

fast conversion with good results (cbr @320)

On the "Ease of Use" I gave it 4,5 start because there is no app interface when you first open the app and the only thing you have to start your work is the choices from the menu bar.

cheers !

hi freekzak,
are you saying you can rip cds plus the cue sheet in one button press?

..."I downloaded because it is the only app that can split mp3 files (or flac,ape etc) with cue info files…"


cheekypaul, he said "split" not "rip".

It works great when you have downloaded an album that was ripped as a single file with a cue file. It will then split them apart.

Maybe it can do this from a CD, but I have not tried it since I have no need to import a CD that way.


hi RavenNevermore,
yes, you're right, clarification is important!
i meant - split to cd tracks from a continuous cd audio file (aif/wav) using a cd cue sheet. i assume so.
i do wonder if it 'pads' the mp3 files (tiny silences at the beginning and end) though? not so good for contiguous mixes. maybe it doesn't, maybe it does… i'll have to experiment.


Hi cheekypaul,

OK, I checked, and yes, it will save a CD as a single file with a cue sheet.

It has pre-gaps listed for individual files.
