S3M to TTA Converter
Processing entirely on your device — large files may take a moment.
ScreamTracker 3 Module and True Audio exist for different jobs: S3M is the ScreamTracker 3 module format — the sound of DOS-era demoscene and shareware-game soundtracks. Convert TTA to FLAC or MP3 for everyday playback.
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 S3M format
S3M is ScreamTracker 3's module format — the 1994 standard that carried PC demo music past the AdLib's FM chip into sampled instruments, with PCM samples, FM instruments or both in one file. Half the classic DOS game soundtracks you remember were S3Ms.
Conversion renders the module through the tracker engine to MP3 or WAV — the FM-vs-sample mix is resolved exactly the way the composer intended, frozen into a universally playable waveform.
+ Strengths
- ✓FM + PCM hybrid instruments
- ✓Iconic DOS-era game soundtracks
- ✓Well-specified, stable format
! Limitations
- −Pattern limits of 1994
- −FM playback differs across engines
- −Adlib-specific quirks may differ
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

Think of it as moving your file to the container that fits the job. Pattern limits of 1994 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 S3M 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 S3M 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 S3M to TTA reduce audio quality?
If TTA is lossless, the output contains everything the S3M 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.
Are tags like title and artist preserved?
Tag handling varies between target formats and this conversion focuses on the audio itself. For archival copies where tags matter, keep the original file; the converted copy is for playback and sharing.
