Colibri Lossless is an open-source lossless audio codec similar to FLAC and ALAC. It aims to deliver CD-quality audio in smaller file sizes without losing any audio data.
Colibri Lossless is an open-source lossless audio codec for encoding and decoding digital audio into a reduced file size without losing any of the original audio data. It is comparable to other popular lossless formats like FLAC, ALAC, and Monkey's Audio.
Developed by the Sound Libre project, Colibri Lossless uses compression techniques that preserve 100% of the original uncompressed CD-quality audio in the encoded file. This allows listeners to decode the Colibri files and play back bit-perfect, CD-quality audio. The compression savings allow for more efficient storage and transmission of high-resolution audio.
Some key features of the Colibri Lossless codec include support for sample rates up to 192 kHz, bit depths up to 32-bit, and multi-channel audio up to 8 channels. Metadata like album art, tags, etc. are preserved in the encoding. Fast and efficient encoding/decoding algorithms provide smaller files than older formats like WAV and AIFF while maintaining lossless quality.
The format specifications and source code for Colibri Lossless encoder/decoder have been published under open source licenses to enable community-driven development and integration into open source audio players and servers. Adoption remains limited compared to more popular alternatives, but it represents a free, open, and efficient solution for lossless audio archiving.
