MKV to DTS Conversion FAQ
How do I extract the audio from my MKV file as DTS?
+
Upload the MKV file and the converter demuxes the audio stream, then transcodes it to DTS. There is no second video pass — the visual track is discarded immediately so extraction is much faster than a full re-encode. MKV is Matroska, an open container designed in 2002 with no licensing restrictions and no ceiling on what it can hold. DTS is Digital Theater Systems audio, the cinema-derived rival to Dolby Digital that appeared on laserdisc and DVD from 1993.
Is converting MKV to DTS a second round of lossy compression?
+
Yes, and it is worth planning around. Both formats are lossy, so the DTS encoder is working from audio that has already been through one psychoacoustic pass, and its own decisions compound the first set. At 192 kbps or above the result is still transparent for most listening. If you have a lossless master anywhere, encoding the DTS from that instead avoids the double pass entirely. MKV is codec-agnostic: H.264, HEVC, VP9 and AV1 video sit happily beside AAC, FLAC, Opus, DTS or Dolby audio in the same file. DTS is lossy multichannel audio at a much higher bitrate than AC-3 — typically 768 to 1509 kbps for 5.1.
What audio bitrate does the extracted DTS use?
+
A lossy DTS is encoded at 192 kbps by default. The Audio Quality setting also offers 320 kbps for the best quality and 128 kbps for a smaller file. A lossless DTS (WAV, FLAC) ignores the bitrate and keeps every sample.
Will I lose audio quality going from MKV to DTS?
+
If DTS is lossless (WAV, FLAC), every sample is preserved exactly. If DTS is lossy (MP3, AAC, OGG, Opus), the DTS codec recompresses the source audio — at 192 kbps the result is transparent for almost all content. Going lossy → lossless never recovers detail already discarded.
Can I extract audio from multiple MKV files to DTS in one batch?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
How long does extracting DTS audio from a 1-hour MKV take?
+
It depends on the size and length of the file. Small documents and images are usually ready quickly. Long videos take the longest, because most video conversions re-encode every frame.
Can I extract just a section of the MKV audio as DTS?
+
Not in this tool directly — extract the full audio as DTS, then use /audio-trim/ or /audio-cutter/ to clip the section. The two-step path is usually faster than a combined operation and gives you precise waveform-level control.
Is my MKV file private during the audio extraction?
+
Yes. Uploaded MKV files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted DTS are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
Why does the DTS file have silent gaps where the MKV had sound?
+
Usually the MKV carries more than one audio track and the one that was converted is silent or secondary. The converter picks one audio track automatically, normally the main one, and this page has no setting to choose a different track. If the wrong one comes out, remux the MKV with the track you want first (VLC or ffmpeg can do this) and convert it again.
DTS (Digital Theater Systems) is a series of multichannel audio technologies known for high-quality audio playback. It is often used in surround sound systems.
