OggFLAC

OggFLAC is a free and open source audio codec that combines the Ogg container format with the FLAC lossless audio compression algorithm. It is designed to provide high-fidelity audio playback with efficient file sizes, without compromising on the original audio quality. FLAC, which stands for Free Lossless Audio Codec, achieves compression by removing redundancy in audio data without discarding any information. This means that when an OggFLAC file is decoded, the audio is identical to the original source.

The Ogg container format, developed by the Xiph.Org Foundation, is a flexible multimedia container that can hold various types of data, including audio, video, and metadata. By using Ogg as the container for FLAC audio, OggFLAC benefits from Ogg's features such as streaming capabilities, seeking, and support for multiple audio and video streams. This combination is often used for archiving music collections and for audiophiles who prioritize preserving the original sound quality.

OggFLAC is widely supported by many audio players and software applications, although it may not be as universally recognized as some other audio formats. Its open-source nature ensures that it is freely available for use and modification, contributing to its adoption in various audio-related projects. The format offers a good balance between file size and audio fidelity, making it a popular choice for those seeking a high-quality, uncompressed audio experience.
