MKV to DTS Conversion FAQ
How do I extract just the audio track from MKV as DTS?
+
Upload the MKV file and the converter demuxes the audio stream from the MKV container, then transcodes it into DTS. Video frames are discarded — no second video pass, no quality loss beyond what the DTS codec itself introduces. 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.
Which audio track gets extracted when my MKV has several?
+
One track, picked automatically: normally the main one, the track with the most channels. This page has no setting to choose a different track and does not list the tracks in the file. If you need commentary or a dub instead, remux the MKV with that track first (VLC or ffmpeg can do this) and convert it again.
What bitrate does the DTS file 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 going from MKV to DTS reduce my audio quality?
+
If the DTS format is lossless (WAV, FLAC, ALAC), every original sample is preserved. If DTS is lossy (MP3, AAC, OGG, Opus), the codec recompresses — at 192 kbps the difference is inaudible for most content; at 96 kbps you may hear cymbals or sibilants softening. The MKV container has no influence on this — only the codec settings matter.
Does the extracted DTS keep the MKV sample rate?
+
By default yes — 48 kHz MKV audio becomes 48 kHz DTS audio, 44.1 kHz becomes 44.1 kHz. If you need to downsample for compatibility (e.g. 96 kHz studio masters to 44.1 kHz CD-quality DTS) the sample-rate dropdown does this with high-quality resampling.
Can I batch-extract DTS audio from a folder of MKV files?
+
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 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.
Is my MKV private during 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 my DTS have silent gaps or wrong audio?
+
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.
