MOD to GSM Converter
Processing entirely on your device — large files may take a moment.
Convert GSM speech recordings to WAV or MP3. If your files are still in MOD format, this page is the shortcut: MOD is the Amiga tracker format — samples plus a pattern table that the demo scene turned into an art form, replayed through its own synthesizer.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.
How MOD compares to GSM
| MOD | GSM | |
|---|---|---|
| Structure | M.K. sample headers + pattern table | Raw GSM frames (33 bytes/20ms) |
| Types / schema | Tracker module (samples + notes) | Lossy speech codec (RPE-LTP) |
| Compatibility | libopenmpt, ProTracker, ffmpeg | Asterisk, SoX, ffmpeg |
| Best for | Demoscene and game music | Telephony recordings |

About the MOD format
MOD is where digital music composition started for a generation: the Amiga tracker format stores short PCM samples plus a pattern table of note events, and the player synthesizes the song live. It is not a waveform — it is sheet music and an instrument pack in one file, which is why 30KB can hold a full song.
Converting MOD to MP3 or WAV renders the song through the tracker engine exactly as it sounds — every player interprets the same patterns, so the render is faithful to the original scene release.
+ Strengths
- ✓Complete songs in tens of kilobytes
- ✓Rich demo-scene heritage
- ✓Self-contained samples + patterns
! Limitations
- −31 8-bit samples max in classic MOD
- −Player interpretation varies subtly
- −4-channel-era limitations
About the GSM format
GSM 06.10 is the speech codec of the original GSM mobile network — 13 kbit/s RPE-LTP that made digital cellphone calls possible in 1991 and still lives inside VoIP systems, old answering machines and Asterisk PBX recordings.
It is lossy speech, not music: converting GSM to WAV or MP3 preserves intelligibility perfectly while finally letting desktop players open the file without special codecs.
+ Strengths
- ✓Tiny bitrate for speech intelligibility
- ✓Ubiquitous in telephony systems
- ✓Decodes natively via ffmpeg
! Limitations
- −Speech-only quality — music falls apart
- −13 kbit/s artifacts are audible
- −8000 Hz sample rate only
Why convert MOD to GSM?
There is a concrete reason this conversion exists: 31 8-bit samples max in classic MOD GSM sidesteps that — Tiny bitrate for speech intelligibility If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this MOD to GSM 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 MOD to GSM?
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.
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.
Can I convert a whole folder of MOD 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.
