 `libymfm.wasm` provide high-level and low-level WebAssembly interfaces to ymfm's sound chips and additional sound chips.
 
-The high-level interface provides the vgm/xgm sequencer, while the low-level interface provides direct access to the sound chip.
-Both can get PCM binary at a specified sampling rate and number of frames.
