A pure Go library for decoding and encoding FLAC (Free Lossless Audio Codec) audio streams.
flac is a Go package that provides comprehensive access to FLAC (Free Lossless Audio Codec) streams. It enables Go applications to decode and encode lossless audio files, supporting both reading metadata and audio frames as well as creating new FLAC files. The library focuses on providing a pure Go implementation of the FLAC specification, emphasizing correctness, performance, and a clean API for audio processing tasks.
Go developers working with audio processing, such as those building media players, audio editing tools, or applications that need to manipulate FLAC files programmatically. It is also suitable for developers requiring a robust, native Go solution for parsing or generating FLAC metadata and frames.
Developers choose this package for its pure Go implementation, which avoids external dependencies and C bindings, ensuring portability and ease of integration into Go projects. It offers a clean API with features like seek support, robust parsing against corrupt files, and experimental encoding capabilities, making it a comprehensive solution for FLAC handling in Go.
Package flac provides access to FLAC (Free Lossless Audio Codec) streams.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
No external C dependencies, ensuring easy integration and cross-compilation in Go projects, as emphasized in the project philosophy.
Handles corrupt files and various encodings like Fixed and LPC prediction, with fuzzing tests and updates to improve resilience, as seen in the changelog.
Provides navigation within FLAC streams for audio playback, with performance improvements like buffered readers in recent versions.
Supports reading and writing standard FLAC metadata blocks such as StreamInfo and Vorbis comments through the dedicated meta subpackage.
The encoding feature is labeled as experimental, making it unstable and unsuitable for production use in creating FLAC files, as admitted in the README.
Focuses on low-level stream access, requiring more code for common audio tasks compared to libraries with built-in playback or editing features.
Example tools were moved to a separate repository, reducing immediate learning resources and practical guidance for developers.
