Function decodeSoundFont

decodeSoundFont(
    data: ArrayBuffer | ArrayBufferView<ArrayBufferLike>,
    decode: SoundFontSampleDecoder,
    limits?: SoundFontLimits,
): Promise<ArrayBuffer>
Decodes a SoundFont 3 into a plain SoundFont 2: every compressed sample a preset reaches (Ogg Vorbis, Ogg Opus or FLAC, told apart by its first bytes) goes through decode (one call per sample, given the codec, returning mono 16-bit frames at the rate the header states) into the sample chunk, and the loop points a SoundFont 3 states relative to its sample become the absolute ones SoundFont 2 uses. A SoundFont 2 comes back unchanged and decode is never called. The result feeds everything that takes SoundFont 2 bytes, renderMidiToBufferAsync included. A loop that ends past the decoded frames is cut to them. limits raises or lowers what a sample and the whole font may decode to (see SoundFontLimits).
Parameters
- data: ArrayBuffer | ArrayBufferView<ArrayBufferLike>
- decode: SoundFontSampleDecoder
- limits: SoundFontLimits = {}
Returns Promise<ArrayBuffer>
Example
```
import { decodeSoundFont, webAudioSampleDecoder } from '@datamoc/mwg/audio';

declare const sf3Bytes: ArrayBuffer;

const sf2 = await decodeSoundFont(sf3Bytes, webAudioSampleDecoder());
console.log(sf2.byteLength);
```
