Colibri supports the most widely used range of file formats in terms of lossless audio: FLAC, ALAC, WAV, AIFF, APE, TTA, DSD, WavPack, popular lossy formats: Ogg Vorbis, MP1/MP2/MP3 and AAC/M4A, network streams/online radio, MOD and MIDI files (with per song SoundFont support)! For your undisturbed listening pleasure, Colibri supports Exclusive/Hog mode as well. A lossless audio player at heart with love to other popular formats as well.

Uses a barely noticable amount of computing power, Colibri is built using state-of-the-art Swift programming language while the BASS audio engine is bundled as machine code and the interface uses built-in components by Apple. This was done in order to achieve a tiny footprint and to be as native to macOS as humanly possible.
