Quick answer: To convert DTS to M4A, add the DTS file to the iHateFiles DTS to M4A converter and press Convert. The conversion runs in your browser, so the file is never uploaded, and it is free with no sign-up, watermark or size limit. DTS is a format most software has stopped opening. M4A is not.
Should you convert DTS to M4A?
Yes. Very little current software opens DTS, so converting it is the way to keep listening to it. Pick a generous bitrate.
Both DTS and M4A are lossy
DTS (DTS surround) has already discarded some of the sound, and M4A (AAC) will discard a little more. The M4A encoder works from the DTS, not the original recording, so pick a bitrate at or above the source. A lower one saves space and costs quality you cannot get back.
Where the M4A will play
M4A plays on Apple devices, Android, browsers and most modern players.

What usually goes wrong
About the DTS. Playing DTS on a device that cannot decode it produces silence or static rather than an error, which looks like a broken file.
About the M4A. M4A, M4B, M4R and AAC are largely the same thing with different extensions. Renaming usually works, though it is not something to rely on.
How to convert DTS to M4A
- Add your DTS file. It is read from your disk and stays there.
- Check the settings. The output format is already set to M4A.
- Press convert and the M4A file is saved back to your device.
Questions
How do I convert DTS to M4A?
Open this page, add your DTS file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.
Is this DTS to M4A converter free?
Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.
Are my files uploaded anywhere?
No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.
Is there a file size limit?
No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.
Will converting to M4A lose quality?
M4A is a lossy format, so some detail is discarded. The quality control on this page decides how much. The default is set high enough that most people cannot see the difference.
Can I convert several DTS files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
