# OpusScript
|
||||
|
||||
JS bindings for libopus 1.3.1, ported with Emscripten.
|
||||
|
||||
----
|
||||
|
||||
## Usage
|
||||
|
||||
```js
|
||||
var OpusScript = require("opusscript");
|
||||
|
||||
// 48kHz sampling rate, 20ms frame duration, stereo audio (2 channels)
|
||||
var samplingRate = 48000;
|
||||
var frameDuration = 20;
|
||||
var channels = 2;
|
||||
|
||||
// Optimize encoding for audio. Available applications are VOIP, AUDIO, and RESTRICTED_LOWDELAY
|
||||
var encoder = new OpusScript(samplingRate, channels, OpusScript.Application.AUDIO);
|
||||
|
||||
var frameSize = samplingRate * frameDuration / 1000;
|
||||
|
||||
// Get PCM data from somewhere and encode it into opus
|
||||
var pcmData = new Buffer(pcmSource);
|
||||
var encodedPacket = encoder.encode(pcmData, frameSize);
|
||||
|
||||
// Decode the opus packet back into PCM
|
||||
var decodedPacket = encoder.decode(encodedPacket);
|
||||
|
||||
// Delete the encoder when finished with it (Emscripten does not automatically call C++ object destructors)
|
||||
encoder.delete();
|
||||
```
|
||||
|
||||
## Note: WASM
|
||||
|
||||
If your environment doesn't support WASM, you can try the JS-only module. Do note that the JS-only version barely has optimizations due to compiler/toolchain limitations, and should only be used as a last resort.
|
||||
|
||||
```js
|
||||
var encoder = new OpusScript(samplingRate, channels, OpusScript.Application.AUDIO, {
|
||||
wasm: false
|
||||
});
|
||||
```
|
||||
|
||||
## Note: TypeScript
|
||||
|
||||
Since this module wasn't written for TypeScript, you need to use `import = require` syntax.
|
||||
|
||||
```ts
|
||||
// Import using:
|
||||
import OpusScript = require("opusscript");
|
||||
|
||||
// and NOT:
|
||||
import OpusScript from "opusscript";
|
||||
```
