说明
flac encodes and decodes audio in the Free Lossless Audio Codec format. FLAC provides lossless compression, meaning the audio is identical to the original after decoding. The tool handles encoding, decoding, testing, and metadata operations. FLAC files are typically 50-60% of the original size while maintaining perfect audio fidelity.
