TTA to M4A Converter
FileFlip converts TTA to M4A entirely inside your browser, using WebCodecs and FFmpeg compiled to WebAssembly. The file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. That means no file-size limit, no queue and no account.
How do I convert a TTA file to M4A?#
- Drop your TTA file onto the converter at the top of this page, or click it to pick one from your computer. You can add as many as you like.
- Leave the target set to M4A and the conversion starts on its own. FileFlip usually downloads nothing, falling back to 30.8 MB of WebAssembly if your browser cannot encode these codecs itself, then runs WebCodecs and FFmpeg on your own machine.
- Save the M4A file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting TTA to M4A lose quality?#
Sometimes. When the codecs inside the TTA file are ones the M4A container can hold, the streams are copied straight across and nothing at all is lost. When they are not, the file has to be decoded and encoded again, and that step does cost a little quality.
Is it safe to convert TTA files online?#
Yes, because nothing is uploaded. FileFlip converts TTA files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.
What TTA to M4A actually does to the file#
Converting TTA to M4A runs on WebCodecs and FFmpeg, usually downloads nothing, falling back to 30.8 MB of WebAssembly if your browser cannot encode these codecs itself, copies the streams through when the codecs fit and re-encodes when they do not.
| Engine | WebCodecs and FFmpeg |
|---|---|
| Conversion path | One step: TTA → M4A |
| Downloaded to your browser | Nothing in most browsers, or 30.8 MB if yours cannot encode these codecs itself |
| Quality | Lossless when the codecs fit, lossy when they do not |
| You get back | One file |
| Where it runs | In a background worker, so the page stays responsive |
What survives the conversion
| What is in the file | This conversion | Why |
|---|---|---|
| Encoded streams | Sometimes | Survives for some files and not others. |
Worth knowing before you start:
- whether the browser can do this without FFmpeg depends on the codecs it exposes through WebCodecs
- the encoded streams are copied when the file's codecs fit the target container, and re-encoded when they do not
What is a TTA file?#
A TTA file holds audio compressed with True Audio, a lossless codec built by Aleksander Djuric around real-time hardware encoding, so it decodes with very little CPU overhead compared to other lossless formats.
There is little reason to choose TTA over FLAC for a new lossless rip today; it mainly persists in existing archives and on older hardware players that already support it.
Convert TTA to FLAC for playback on current phones, players, and software, since FLAC covers the same lossless ground with far wider support.
What is an M4A file?#
An M4A file is an MPEG-4 audio container, almost always holding AAC-compressed audio and occasionally Apple Lossless (ALAC), that Apple labels with the .m4a extension to mark an MPEG-4 file as audio-only rather than video.
Use M4A for anything staying inside Apple's ecosystem, especially iTunes and Music libraries and Apple Lossless archives.
Convert M4A to MP3 for compatibility with players and devices that don't support AAC, or to FLAC if the M4A holds ALAC and you want a more widely supported lossless format.
TTA to M4A questions people ask#
What creates a TTA file?
TTA files come from ripping or archiving software that specifically chose the True Audio codec, most often foobar2000 or other Windows-based lossless ripping tools, and from a handful of portable media players that supported TTA natively before FLAC decoding became cheap enough for their hardware.
What still plays TTA files?
foobar2000 plays TTA natively on Windows, and VLC decodes it on any platform. Support outside those tools is thin; most phones and streaming apps have never supported the format.
Should I convert TTA to FLAC?
Convert TTA to FLAC when the file needs to play on a device or app that does not recognize True Audio, which in practice is most modern software. Both are lossless codecs, so the converted file reproduces the exact original audio with nothing discarded.
Is M4A the same as MP3?
No, M4A and MP3 are different codecs in different containers. M4A almost always holds AAC audio, a newer codec that sounds better than MP3 at the same bit rate, wrapped in an MPEG-4 container; MP3 is both the codec and the file format at once. They aren't interchangeable without converting.
