MP3 to DTS Conversion FAQ
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.
Is converting MP3 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. MP3 is lossy: a psychoacoustic model discards frequencies the ear is unlikely to notice, typically at 128 to 320 kbps. DTS is lossy multichannel audio at a much higher bitrate than AC-3 — typically 768 to 1509 kbps for 5.1.
Will my track titles and album art survive the MP3 to DTS conversion?
+
Not intact. MP3 carries a proper metadata block, but DTS has no standard place for artist, album, track number or cover art, so tags are dropped rather than mangled. Keep the MP3 as the tagged copy, or re-tag afterwards with a tool like Mp3tag or MusicBrainz Picard. DTS licensing means most TVs, soundbars and every browser refuse it, so it usually has to become AAC or AC-3 to be usable.
Will the DTS play in my car or on older hardware?
+
Often not. MP3 is decoded by essentially everything, including car head units and elderly players; DTS needs software that knows the codec, which standalone hardware frequently does not have. If the destination is a car stereo or a portable player, that is a strong argument for staying on MP3.
Will going from MP3 to DTS reduce my audio quality?
+
If MP3 is lossy and DTS is lossless (e.g. MP3 → WAV), the DTS file is no better than the MP3 — you can't recover information that's already been thrown away. If MP3 is lossless and DTS is lossy, expect the DTS codec to recompress; at 192 kbps this is transparent for most content.
Can I batch convert hundreds of MP3 files to DTS?
+
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.
Will the DTS keep the same sample rate as MP3?
+
By default yes (48 kHz MP3 → 48 kHz DTS). If you need to downsample for compatibility (e.g. 96 kHz → 44.1 kHz for CD burning) the advanced sample-rate option does this with high-quality resampling.
Can I normalize loudness in the MP3 to DTS step?
+
Not in this step. The converter has no loudness setting and leaves the level as it is. To even out the volume, run the finished DTS through a Normalize tool on this site.
Will the DTS play on my car stereo / iPod / audiobook app?
+
MP3 plays almost everywhere. AAC plays on Apple devices, most Android phones and Sonos. FLAC plays on Sonos and Android but not on older iPods, and WAV plays on nearly everything but makes large files. There are no device presets on this page, so choose the target format your player supports.
Is my MP3 file private during conversion?
+
Yes. Nobody listens to or shares the audio, which matters for personal audiobook libraries, and uploaded MP3 files and their converted copies are deleted automatically about 24 hours after conversion.
