How AMR to FLAC conversion works

AMR decode → normalized audio stream → FLAC encode

Reading AMR

AMR input is optimized for narrowband or wideband speech and may have limited metadata.

Creating FLAC

FLAC output preserves audio samples losslessly while reducing size compared with uncompressed PCM.
