Sound playback system
M3S-S2-Tiny (hereafter abbreviated S2) is the sound playback system which just requires small memory.
We have the various lineup of MCUs, including RX Family, which are suitable for use in applications such as single-function home appliances and compact industrial equipment, where the incorporation of more sophisticated functionality or the newest technology, with a negligible increase in cost, is desired. To support such development activities, Renesas offers software libraries with only the essential features for application, at low cost.
Use S2 to enable sound output in any device incorporating a target microcontroller. S2's original algorithm compresses and expands sound in ADPCM mode compactly at high speed. It can be used to add true sound output functionality to devices that previously only provided visual indications or beeps.
* The compressible formats are 16 bits quantized monaural PCM (files in wav format).
