constructor

new OpusDecoder(sampleRate, channels): OpusDecoder
Create an opus decoder.
Parameters
- sampleRate: number
  Sample rate to decode at (Hz). This must be one of 8000, 12000, 16000, 24000, or 48000.
- channels: number
  Number of channels (1 or 2) to decode.
Returns OpusDecoder
- Defined in index.d.ts:220

Methods

decode

decode(data, frameSize): Buffer
Decodes an Opus packet to 16-bit signed integer PCM.
Parameters
- data: Buffer
  The data of the opus packet to decode.
- frameSize: number
  Number of samples per channel in the opus packet. This must be an Opus frame size for the encoder's sampling rate.
Returns Buffer
The output signal in 16-bit signed integer PCM.
- Defined in index.d.ts:228

decodeFloat

decodeFloat(data, frameSize): Buffer
Decodes an Opus packet to floating point PCM.
Parameters
- data: Buffer
  The data of the opus packet to decode.
- frameSize: number
  Number of samples per channel in the opus packet. This must be an Opus frame size for the encoder's sampling rate.
Returns Buffer
The output signal in floating point PCM.
