AMR to TTA Converter
Processing entirely on your device — large files may take a moment.
Convert TTA to FLAC or MP3 for everyday playback. If your files are still in AMR format, this page is the shortcut: AMR is the tiny voice-recording format of old Nokia-era phones and answering machines.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

About the AMR format
AMR (Adaptive Multi-Rate) is the speech codec of 2G/3G telephony, and the default recording format of countless feature phones and early smartphones. It is optimized exclusively for human voice: narrowband (300–3400 Hz) and wideband (AMR-WB, 50–7000 Hz) modes that make calls sound like calls.
For voice memos it is remarkably compact — a few kilobits per second. For anything musical it is hopeless: cymbals, bass and anything above its band simply do not exist. Convert AMR voice notes to MP3/Opus for archiving and playback anywhere else.
+ Strengths
- ✓Extremely compact for speech
- ✓Native phone-recorder format
! Limitations
- −Voice-only: music quality is unusable
- −Narrow bandwidth sounds dated
About the TTA format
TTA (True Audio) is a no-frills real-time lossless compressor: simple 32-bit crypto-free checksums, multi-threadable encoding and IDs at both frame and file level. It filled the lossless niche on slow connections and in Russian archive communities where FLAC arrived late.
Decoding is near-instant and lossless, so converting TTA to FLAC or MP3 costs nothing in fidelity — the audio is identical, the compatibility is finally universal.
+ Strengths
- ✓Real-time speed on modest hardware
- ✓Simple, well-documented container
- ✓Error-tolerant frame structure
! Limitations
- −Compression ratios behind modern codecs
- −Ecosystem largely inactive
- −Tagging support is weak
Why convert AMR to TTA?
Think of it as moving your file to the container that fits the job. Voice-only: music quality is unusable TTA works differently: Real-time speed on modest hardware If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this AMR to TTA converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for AMR to TTA?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Will converting AMR to TTA reduce audio quality?
If TTA is lossless, the output contains everything the AMR file contains — no further loss is added. If TTA is lossy, one recompression pass is unavoidable; the quality slider controls how much. Loss that already happened in the source file can never be undone by converting.
Can I convert a whole folder of AMR files?
You can select many files at once and they are processed in a single batch. Output files land in one ZIP download when there is more than one result.
