About Free Lossless Audio Codec
Common Use Cases
- Decoding DTS surround audio for media server playback
- Archiving decoded DTS audio in lossless format
- Playing DTS content on devices without DTS decoders
DTS is a surround sound codec found in Blu-ray discs, DVDs, and movie files. While it sounds excellent through a proper home theater system, many media players, portable devices, and servers cannot decode DTS natively. FLAC is a universally supported lossless format. Converting DTS to FLAC decodes the surround audio and stores it in a lossless container that works everywhere.
DTS is a compressed surround sound codec (lossy for standard DTS, lossless for DTS-HD MA), while FLAC is an open lossless format with universal player support. The conversion decodes the DTS audio and wraps it in a FLAC container.
Why Convert DTS to FLAC?
Universal player compatibility
FLAC plays on every media player, server, and device. DTS requires specialized decoders that are not available on many portable players, phones, and standard media software.
Media server native playback
Plex, Jellyfin, and Roon play FLAC natively. DTS often requires server-side transcoding, which consumes CPU and can introduce latency or quality loss.
Multichannel preservation
FLAC supports multichannel audio. A 5.1 DTS track produces a 6-channel FLAC with all surround channels intact.
Lossless archival
FLAC is a standard archival format. Storing decoded DTS audio as FLAC ensures long-term access without relying on DTS decoder availability.

Frequently asked questions
- Is converting DTS to FLAC lossless?
- For DTS-HD Master Audio, yes. The decode is fully lossless. For standard DTS (lossy), the FLAC losslessly preserves the decoded lossy audio, but quality is limited by the DTS source.
- Will surround channels be preserved?
- Yes. FLAC supports multichannel audio. A 5.1 DTS track becomes a 6-channel FLAC, and 7.1 becomes an 8-channel FLAC.
- Can I play multichannel FLAC in Plex?
- Yes. Plex handles multichannel FLAC natively. It is a much better choice than DTS for Plex because it avoids forced transcoding.
- Why is the FLAC so much bigger than the DTS?
- Standard DTS uses lossy compression, while FLAC uses lossless compression. Lossless encoding produces larger files because it preserves every sample of the decoded audio.
- Is converting DTS to FLAC free?
- Yes. Anyone can convert for free with no signup. Anonymous users have a daily cap, registered accounts get higher limits, and Premium or Lifetime members get unlimited conversions.
- What about DTS-HD Master Audio?
- FFmpeg decodes DTS-HD MA (lossless) fully. The resulting FLAC is a perfect lossless representation of the original master audio.
- Is there a file size limit?
- Yes. The maximum upload size is 500 MB.
