Encoder

class Encoder extends AnyRef

Wrapper around the Opus codec's encoder subsystem. The C interface is documented at http://www.opus-codec.org and should be considered definitive. The encoder accepts buffers of duration of 2,5, 5, 10, 20, 40 or 60ms. To calculate the buffer size, multiply your sample frequency by the frame duration. At 8kHz a 20ms packet is 160 samples long.

Instance Constructors

  1. new Encoder(sampleFreq: SampleFrequency, channels: Int, app: Application, bufferSize: Int = 8192)

    sampleFreq

    The required sampling frequency

    channels

    The number of channels you intend to encode.

    app

    The application (Voip, Audio or LowDelay)

    bufferSize

    The reserved size of the buffer to which compressed data are written. The default should be more than sufficient

  6. def apply(audio: Array[Float]): Try[Array[Byte]]

    Encode a block of raw audio in float format using the configured encoder

    Encode a block of raw audio in float format using the configured encoder

    audio

    Audio data arranged as a contiguous block interleaved array of floats

    returns

    An array containing the compressed audio or the exception in case of a failure

  7. def apply(audio: Array[Short]): Try[Array[Byte]]

    Encode a block of raw audio in integer format using the configured encoder

    Encode a block of raw audio in integer format using the configured encoder

    audio

    Audio data arranged as a contiguous block interleaved array of short integers

    returns

    An array containing the compressed audio or the exception in case of a failure

  9. var clean: Boolean

  10. def cleanup(): Unit

    Release all pointers allocated for the encoder.

    Release all pointers allocated for the encoder. Make every attempt to call this when you are done with the encoder as finalise() is what it is in the JVM
