Native Lossless Audio for macOS with BS2B support

Colibri is a native macOS audio player built from scratch on top of the award-winning BASS technology, supports cristal-clear bit-perfect playback of all popular lossless and lossy audio formats, uses only a tiny amount of computing power and offers a clean and intuitive user experience.

Saves your battery
Colibri uses a barely noticable amount of computing power during the playback of your music.

Plays your audio
- FLAC, ALAC, WAV, AIFF, APE, TTA, DSD (DSDIFF and DSF encoding), WavPack
- Ogg Vorbis, MP1/MP2/MP3 and AAC/M4A
- network streams/online radio
- Chiptune and Tracker music
- MOD and MIDI files (with per song SoundFont support)
- 10-band Equalizer
- Automatic Sample Rate Switching

Handles CUE Sheets
Reads, processes - and to some extent - sanitizes cue sheets

Supports gapless playback
Colibri is extensively designed from the ground-up to provide a true gapless listening experience - with or without using a Cue Sheet.

Picks up where you left off
Saves your current playlist upon quitting and re-opens your songs when you start it up again.

Avoids most problems
Colibri does its' best to avoid most problems before, during and after playback.

Understands your language
Colibri is capable of rendering the song information as it was intended to be shown: of all the tried metadata it had no problem with displaying cyrillic or kanji/katakana/hiragana characters mixed with ASCII.

Respects your privacy
Colibri does not phone home, collect usage data or modify files in any way.

Displays album art - Colibri displays embedded cover art for FLAC files and ID3/iTunes artwork metadata for other files (mainly M4A / ALAC and MP3). When that yields not results then it looks in the folder where the current song resides for a cover art image.

Resides in your Menu Bar
Colibri can place an unobtrusively small icon in the Menu Bar for easy access and playlist control

Integrates with Finder
Colibri conforms all of Apple's strict requirements

Adjusts to your Display
Colibri's interface elements scale themselves nicely on every screen resolution and pixel density.

What’s New

Version 1.9.1

Thank you for using Colibri! This updates brings a bunch of bugfixes, eight new columns and some smaller enhancements. Happy listening!

- Volume is now automatically raised to 100% for DSD files when DoP/DoPA mode is selected and restored to previous volume level for non-DSD files (and PCM mode)
- Unsupported DST encoded DSD and DTS encoded WAV files will now show proper Unsupported Codec error messages
- Finder sorting order is used to enqueueing files to the Playlist
- Playlist will be rendered with system default monospace font when available (macOS 10.11 and up)
- added a 'Use Default SoundFont' option for MIDI files to the right-click context menu of the Playlist
- removing the default SoundFont will automatically set the next available SoundFont as the default
- if the SoundFont list is empty, then the first SoundFont will automatically be marked as the default
- removing a SoundFont only causes playback restart if the currently played song is affected by the removal
- importing a new SoundFont will automatically set it as the default
- new switchable option in Settings -> Playlist: "Dragging to the Playlist via Mouse / Trackpad":
+ songs will be added at pointer position (insert)
+ songs will be added at the end of the list (append, like before)
- added 'Permanent Pause' to Settings -> Behavior (Off, by default):
+ pause will 'hold' until the Play button is pressed again
+ switching to a different song will 'arm'/prepare the song for playback
+ seeking repositions the playhead and it will play audio from the selected spot once unpaused
+ removing songs from the playlist does not affect the paused state
- added 'Auto-Play' to Settings -> Behavior (On, by default):
+ On: Colibri automatically plays the next song
+ Off: Colibri stops when the current song ends
- new tab in Settings: Columns
- Columns are now sortable:
+ click on the header once to sort playlist by that column
+ double click switches between Ascending/Descending sorting
- new Columns:
+ Length, kHz, Codec, Year, Track Number, Disc Number, Composer and Bit Depth
- Playlist can now have vertical and horizontal Grids:
+ useful for reordering / resizing
+ set the color in Settings -> Themes
- new Loop option 'Random Round Robin' in Settings -> Playlist:
+ each song in the Playlist will be played once per "round"
+ when all songs were played once, a new "round" begins
- monospace system fonts in Title bar and Status bar (10.11 and up)

- Colibri would not display its' name in the Force Quit and Activity Monitor windows
- Colibri would prevent the system from entering sleep state
- Colibri would fail to play the upcoming song under very high system load
- Playhead wouldn't always continue from the same spot on output device change
- Playlist would have a weird glitch on startup
- Force Sample Rate would cause crash on startup
- Online Streams wouldn't always start playback
- Random playback order would sometime cause Colibri to crash
- BS2B and EQ profiles wouldn't property restore on next startup
- After starting Colibri, the playlist would become disorganized/chaotic if files had gone missing since last start
- Menubar Controller didn't always refresh the data on song change
- multiple SoundFont fixes
- network streams won't trigger a 'Problem calculating song length' error
- Menubar Controller properly shows Light/Dark control buttons as per system theme
- Colibri could crash by clicking on the EQ button while the Playlist is empty
- moving multiple songs in the Playlist at once could cause titles to be become disorganized
- dragging files / folder to the dock would not be added to the Playlist properly
- Colibri could crash on El Capitan 10.11.6 when switching between Dock and Menu modes
- Color Pickers in Settings -> Themes should now behave as expected of them

Thank you Henning Gärtner for all-around essential feedback and testing, Rick Ernsting for feedback on the SoundFont issues!

Killer Potential

I've been using for several months now and I'm blown away with the sound quality. I don't know how he did it but i can't get over how good it sounds. Includes wonderful features for tailoring the sound to your preference. If there's anything i can say it really needs is better library functionality and fix the song sequencing in the album lists. at this time there is only playlist functionality and once that is fixed, this will be a great replacement for iTunes or a myriad of other music apps for the Mac.

Hi! Please look forward to the next update as the sorting issue will be fixed in the new version. I’m also working on library support, but it probably won’t be in the next update as it needs quite a bit of time to get it done right :-) Cheers, Gabor

Crashes CONSTANTLY with Midi Files

You’d think if the software is advertised as supporting Midi and 3rd party sound fonts (.SF2 files), that the developers would have taken the time to at least test out a few different midi files. Apparently not. Because if they had, they would have noticed within 10 minutes how very very unstable Colibri is. I am simply trying to play some christmas midi files found on the net, and Colibri crashes not once in a while, not occasionally, but on every other midi file. And there’s no rhyme or reason to it either. The same file that causes it to crash one moment loads fine the next. Certainly there are poorly written midi files and soundfont banks out there, but Colibri is crashing consistently across a broad variety of different midi files and soundfont banks. It seems impossible to find a decent midi player on the mac with playlist and SF2 support that isn’t prone to crashing. Windows has a few which are rock solid, so this can’t be such a technical feat.

Hi BigErn77, 

Sorry to hear about the crashes! Could you please be so kind as to contact me via '' so that I could try out some of the SoundFonts and MIDI files you had trouble with? I do have an idea which BASS module could be the culprit, but would need your input on it as well to go forward. I do listen to MIDI files myself with Colibri and couldn't reproduce this crashing behavior (I also do test each version before releasing them with various formats/files, including MIDI) - but it seems I have missed something this time around, so sorry for that!

Coming From Audirvana...

Bit perfect playback is fantastic. I'm using this with an iFi Nano BL dac and don't care very much for upsampling. To my ears, it sounds better than Pine Player. It might have to do something with Colibri following the bit rate properly unlike Pine Player which doesn't switch bit rates. Much more lightweight and less CPU intensive than Audirvana with my 2012 Macbook Pro. The only thing missing is the media library. I'm having to add all my folders back manually in Colibri. But all that is explained on the dev's website. Beyond that, I'm very happy with the sound of player itself.
