- v1.0/ — ADPCM, zero external dependencies, ~200–500 KB
- v2.0/ — Opus-based, requires libopus.a (MSYS2:
pacman -S mingw-w64-x86_64-opus), ~1.5–2.5 MB - v3.0/ — Opus-based, Opus-native sample rates pass through, ~1.5–2.5 MB
The three versions are format-incompatible (v1.0 magic = "MSM1", v2.0 magic = "MSM2", v3.0 magic = "MSM3").
Decoders must dispatch by magic; they cannot be mixed.
Build inside each version directory:
build-MSM.bat -> msmcli.exe (CLI: MP3->MSM / MSM->WAV / play MSM)
build-SMP.bat -> smp.exe (GUI player)
See the README.md inside each version directory for the full format spec and usage.
MSM is developed by SimpleToolsStudio (GitHub: @SimpleToolsStudio).
