Free Lossless Audio Codec
FLAC (Free Lossless Audio Codec) is an open-source audio format that compresses audio without any loss of quality. Unlike MP3 or AAC, FLAC preserves the original audio data bit-for-bit while reducing file size by 40-60%. Popular among audiophiles, music archivists, and professional audio engineers, FLAC is the gold standard for high-fidelity audio storage. Our AI-powered transcription service processes FLAC files with 99%+ accuracy, leveraging the pristine audio quality for superior speech recognition across 90+ languages.
