Convert MTS to FLAC — Free Online Converter

AVCHD camcorders record audio as either AC3 (Dolby Digital) at 256-640 kbps or LPCM at 1536 kbps — both substantially higher quality than typical consumer audio recordings. FLAC (Free Lossless Audio Codec) compresses audio by 30-50% without losing a single sample. Converting MTS to FLAC extracts the camcorder's high-quality audio track into a compact lossless format suitable for archiving, editing, and cross-platform distribution.

Camcorder audio often contains irreplaceable recordings — wedding ceremonies, live performances, family milestones, nature soundscapes. FLAC provides the safest archival format because it is lossless (no degradation over any number of accesses), open-source (no vendor lock-in), and compressed (half the size of WAV/AIFF). Unlike AAC or MP3, FLAC guarantees that every future use of the audio starts from the best possible quality.

FLAC is also the preferred format for music archives, radio stations, and institutional sound collections. The format's built-in integrity checking (MD5 fingerprint) ensures that stored files have not been corrupted — an essential feature for long-term audio preservation.
