    • OPUS_SET_COMPLEXITY

      public static Opus.CTLRequest OPUS_SET_COMPLEXITY(int value)
      Configures the encoder's computational complexity.

      The supported range is 0-10 inclusive with 10 representing the highest complexity.

      Parameters:
      value - 0-10, inclusive

    • OPUS_GET_COMPLEXITY

      public static Opus.CTLRequest OPUS_GET_COMPLEXITY(IntBuffer value)
      Gets the encoder's complexity configuration.
      Returns:
      a value in the range 0-10, inclusive

    • OPUS_SET_BITRATE

      public static Opus.CTLRequest OPUS_SET_BITRATE(int value)
      Configures the bitrate in the encoder.

      Rates from 500 to 512000 bits per second are meaningful, as well as the special values OPUS_AUTO and OPUS_BITRATE_MAX. The value OPUS_BITRATE_MAX can be used to cause the codec to use as much rate as it can, which is useful for controlling the rate by adjusting the output buffer size.

      Parameters:
      value - bitrate in bits per second. The default is determined based on the number of channels and the input sampling rate.

    • OPUS_GET_BITRATE

      public static Opus.CTLRequest OPUS_GET_BITRATE(IntBuffer value)
      Gets the encoder's bitrate configuration.
      Returns:
      the bitrate in bits per second. The default is determined based on the number of channels and the input sampling rate.

    • OPUS_SET_VBR

      public static Opus.CTLRequest OPUS_SET_VBR(int value)
      Enables or disables variable bitrate (VBR) in the encoder.

      The configured bitrate may not be met exactly because frames must be an integer number of bytes in length.

      Parameters:
      value - allowed values:
      0
      Hard CBR. For LPC/hybrid modes at very low bit-rate, this can cause noticeable quality degradation.
      1
      VBR (default). The exact type of VBR is controlled by #OPUS_SET_VBR_CONSTRAINT.

    • OPUS_GET_VBR

      public static Opus.CTLRequest OPUS_GET_VBR(IntBuffer value)
      Determines if variable bitrate (VBR) is enabled in the encoder.
      Returns:
      one of the following values:
      0
      Hard CBR.
      1
      VBR (default). The exact type of VBR may be retrieved via OPUS_GET_VBR_CONSTRAINT(java.nio.IntBuffer).

    • OPUS_SET_VBR_CONSTRAINT

      public static Opus.CTLRequest OPUS_SET_VBR_CONSTRAINT(int value)
      Enables or disables constrained VBR in the encoder.

      This setting is ignored when the encoder is in CBR mode. Warning: Only the MDCT mode of Opus currently heeds the constraint. Speech mode ignores it completely, hybrid mode may fail to obey it if the LPC layer uses more bitrate than the constraint would have permitted.

      Parameters:
      value - allowed values:
      0
      Unconstrained VBR.
      1
      Constrained VBR (default). This creates a maximum of one frame of buffering delay assuming a transport with a serialization speed of the nominal bitrate.

    • OPUS_GET_VBR_CONSTRAINT

      public static Opus.CTLRequest OPUS_GET_VBR_CONSTRAINT(IntBuffer value)
      Determines if constrained VBR is enabled in the encoder.
      Returns:
      one of the following values:
      0
      Unconstrained VBR.
      1
      Constrained VBR (default).

    • OPUS_SET_FORCE_CHANNELS

      public static Opus.CTLRequest OPUS_SET_FORCE_CHANNELS(int value)
      Configures mono/stereo forcing in the encoder.

      This can force the encoder to produce packets encoded as either mono or stereo, regardless of the format of the input audio. This is useful when the caller knows that the input signal is currently a mono source embedded in a stereo stream.

      Parameters:
      value - allowed values:
      OPUS_AUTO
      Not forced (default)
      1
      Forced mono
      2
      Forced stereo

    • OPUS_GET_FORCE_CHANNELS

      public static Opus.CTLRequest OPUS_GET_FORCE_CHANNELS(IntBuffer value)
      Gets the encoder's forced channel configuration.
      Returns:
      one of the following values:
      OPUS_AUTO
      Not forced (default)
      1
      Forced mono
      2
      Forced stereo

    • OPUS_SET_MAX_BANDWIDTH

      public static Opus.CTLRequest OPUS_SET_MAX_BANDWIDTH(int value)
      Configures the maximum bandpass that the encoder will select automatically.

      Applications should normally use this instead of OPUS_SET_BANDWIDTH(int) (leaving that set to the default, OPUS_AUTO). This allows the application to set an upper bound based on the type of input it is providing, but still gives the encoder the freedom to reduce the bandpass when the bitrate becomes too low, for better overall quality.

      Parameters:
      value - allowed values:
      OPUS_BANDWIDTH_NARROWBAND
      4 kHz passband
      OPUS_BANDWIDTH_MEDIUMBAND
      6 kHz passband
      OPUS_BANDWIDTH_WIDEBAND
      8 kHz passband
      OPUS_BANDWIDTH_SUPERWIDEBAND
      12 kHz passband
      OPUS_BANDWIDTH_FULLBAND
      20 kHz passband (default)

    • OPUS_GET_MAX_BANDWIDTH

      public static Opus.CTLRequest OPUS_GET_MAX_BANDWIDTH(IntBuffer value)
      Gets the encoder's configured maximum allowed bandpass.
      Returns:
      one of the following values:
      OPUS_BANDWIDTH_NARROWBAND
      4 kHz passband
      OPUS_BANDWIDTH_MEDIUMBAND
      6 kHz passband
      OPUS_BANDWIDTH_WIDEBAND
      8 kHz passband
      OPUS_BANDWIDTH_SUPERWIDEBAND
      12 kHz passband
      OPUS_BANDWIDTH_FULLBAND
      20 kHz passband (default)

    • OPUS_SET_BANDWIDTH

      public static Opus.CTLRequest OPUS_SET_BANDWIDTH(int value)
      Sets the encoder's bandpass to a specific value.

      This prevents the encoder from automatically selecting the bandpass based on the available bitrate. If an application knows the bandpass of the input audio it is providing, it should normally use OPUS_SET_MAX_BANDWIDTH(int) instead, which still gives the encoder the freedom to reduce the bandpass when the bitrate becomes too low, for better overall quality.

      Parameters:
      value - allowed values:
      OPUS_AUTO
      (default)
      OPUS_BANDWIDTH_NARROWBAND
      4 kHz passband
      OPUS_BANDWIDTH_MEDIUMBAND
      6 kHz passband
      OPUS_BANDWIDTH_WIDEBAND
      8 kHz passband
      OPUS_BANDWIDTH_SUPERWIDEBAND
      12 kHz passband
      OPUS_BANDWIDTH_FULLBAND
      20 kHz passband (default)

    • OPUS_GET_BANDWIDTH

      public static Opus.CTLRequest OPUS_GET_BANDWIDTH(IntBuffer value)
      Gets the encoder's configured bandpass or the decoder's last bandpass.
      Returns:
      one of the following values:
      OPUS_AUTO
      (default)
      OPUS_BANDWIDTH_NARROWBAND
      4 kHz passband
      OPUS_BANDWIDTH_MEDIUMBAND
      6 kHz passband
      OPUS_BANDWIDTH_WIDEBAND
      8 kHz passband
      OPUS_BANDWIDTH_SUPERWIDEBAND
      12 kHz passband
      OPUS_BANDWIDTH_FULLBAND
      20 kHz passband (default)

    • OPUS_SET_SIGNAL

      public static Opus.CTLRequest OPUS_SET_SIGNAL(int value)
      Configures the type of signal being encoded.

      This is a hint which helps the encoder's mode selection.

      OPUS_SIGNAL_VOICE
      Bias thresholds towards choosing LPC or Hybrid modes.
      OPUS_SIGNAL_MUSIC
      Bias thresholds towards choosing MDCT modes.

    • OPUS_GET_SIGNAL

      public static Opus.CTLRequest OPUS_GET_SIGNAL(IntBuffer value)
      Gets the encoder's configured signal type.
      Returns:
      one of the following values:
      OPUS_AUTO
      (default)
      OPUS_SIGNAL_VOICE
      Bias thresholds towards choosing LPC or Hybrid modes.
      OPUS_SIGNAL_MUSIC
      Bias thresholds towards choosing MDCT modes.

    • OPUS_SET_APPLICATION

      public static Opus.CTLRequest OPUS_SET_APPLICATION(int value)
      Configures the encoder's intended application.

      The initial value is a mandatory argument to the encoder_create function.

      Parameters:
      value - allowed values:
      OPUS_APPLICATION_VOIP
      Process signal for improved speech intelligibility.
      OPUS_APPLICATION_AUDIO
      Favor faithfulness to the original input.
      OPUS_APPLICATION_RESTRICTED_LOWDELAY
      Configure the minimum possible coding delay by disabling certain modes of operation.

    • OPUS_GET_APPLICATION

      public static Opus.CTLRequest OPUS_GET_APPLICATION(IntBuffer value)
      Gets the encoder's configured application.
      Returns:
      one of the following values:
      OPUS_APPLICATION_VOIP
      Process signal for improved speech intelligibility.
      OPUS_APPLICATION_AUDIO
      Favor faithfulness to the original input.
      OPUS_APPLICATION_RESTRICTED_LOWDELAY
      Configure the minimum possible coding delay by disabling certain modes of operation.

    • OPUS_GET_LOOKAHEAD

      public static Opus.CTLRequest OPUS_GET_LOOKAHEAD(IntBuffer value)
      Gets the total samples of delay added by the entire codec.

      This can be queried by the encoder and then the provided number of samples can be skipped on from the start of the decoder's output to provide time aligned input and output. From the perspective of a decoding application the real data begins this many samples late.

      The decoder contribution to this delay is identical for all decoders, but the encoder portion of the delay may vary from implementation to implementation, version to version, or even depend on the encoder's initial configuration. Applications needing delay compensation should call this CTL rather than hard-coding a value.

      Returns:
      number of lookahead samples

    • OPUS_SET_INBAND_FEC

      public static Opus.CTLRequest OPUS_SET_INBAND_FEC(int value)
      Configures the encoder's use of inband forward error correction (FEC).

      Note: This is only applicable to the LPC layer

      Parameters:
      value - allowed values:
      0
      Disable inband FEC (default).
      1
      Inband FEC enabled. If the packet loss rate is sufficiently high, Opus will automatically switch to SILK even at high rates to enable use of that FEC.
      2
      Inband FEC enabled, but does not necessarily switch to SILK if we have music.

    • OPUS_GET_INBAND_FEC

      public static Opus.CTLRequest OPUS_GET_INBAND_FEC(IntBuffer value)
      Gets encoder's configured use of inband forward error correction.
      Returns:
      one of the following values:
      0
      Inband FEC disabled (default).
      1
      Inband FEC enabled. If the packet loss rate is sufficiently high, Opus will automatically switch to SILK even at high rates to enable use of that FEC.
      2
      Inband FEC enabled, but does not necessarily switch to SILK if we have music.

    • OPUS_SET_PACKET_LOSS_PERC

      public static Opus.CTLRequest OPUS_SET_PACKET_LOSS_PERC(int value)
      Configures the encoder's expected packet loss percentage.

      Higher values trigger progressively more loss resistant behavior in the encoder at the expense of quality at a given bitrate in the absence of packet loss, but greater quality under loss.

      Parameters:
      value - loss percentage in the range 0-100, inclusive (default: 0)

    • OPUS_GET_PACKET_LOSS_PERC

      public static Opus.CTLRequest OPUS_GET_PACKET_LOSS_PERC(IntBuffer value)
      Gets the encoder's configured packet loss percentage.
      Returns:
      the configured loss percentage in the range 0-100, inclusive (default: 0)

    • OPUS_SET_DTX

      public static Opus.CTLRequest OPUS_SET_DTX(int value)
      Configures the encoder's use of discontinuous transmission (DTX).

      Note: This is only applicable to the LPC layer

      Parameters:
      value - allowed valued:
      0
      Disable DTX (default).
      1
      Enabled DTX.

    • OPUS_GET_DTX

      public static Opus.CTLRequest OPUS_GET_DTX(IntBuffer value)
      Gets encoder's configured use of discontinuous transmission.
      Returns:
      one of the following values:
      0
      DTX disabled (default).
      1
      DTX enabled.

    • OPUS_SET_LSB_DEPTH

      public static Opus.CTLRequest OPUS_SET_LSB_DEPTH(int value)
      Configures the depth of signal being encoded.

      This is a hint which helps the encoder identify silence and near-silence. It represents the number of significant bits of linear intensity below which the signal contains ignorable quantization or other noise.

      For example, OPUS_SET_LSB_DEPTH(14) would be an appropriate setting for G.711 u-law input. OPUS_SET_LSB_DEPTH(16) would be appropriate for 16-bit linear pcm input with opus_encode_float().

      When using opus_encode(long, java.nio.ShortBuffer, int, java.nio.ByteBuffer) instead of opus_encode_float(long, java.nio.FloatBuffer, int, java.nio.ByteBuffer), or when libopus is compiled for fixed-point, the encoder uses the minimum of the value set here and the value 16.

      Parameters:
      value - input precision in bits, between 8 and 24 (default: 24).

    • OPUS_GET_LSB_DEPTH

      public static Opus.CTLRequest OPUS_GET_LSB_DEPTH(IntBuffer value)
      Gets the encoder's configured signal depth.
      Returns:
      input precision in bits, between 8 and 24 (default: 24).

    • OPUS_SET_EXPERT_FRAME_DURATION

      public static Opus.CTLRequest OPUS_SET_EXPERT_FRAME_DURATION(int value)
      Configures the encoder's use of variable duration frames.

      When variable duration is enabled, the encoder is free to use a shorter frame size than the one requested in the opus_encode*() call. It is then the user's responsibility to verify how much audio was encoded by checking the ToC byte of the encoded packet. The part of the audio that was not encoded needs to be resent to the encoder for the next call. Do not use this option unless you really know what you are doing.

      Parameters:
      value - allowed valued:
      OPUS_FRAMESIZE_ARG
      Select frame size from the argument (default).
      OPUS_FRAMESIZE_2_5_MS
      Use 2.5 ms frames.
      OPUS_FRAMESIZE_5_MS
      Use 5 ms frames.

      OPUS_FRAMESIZE_80_MS
      Use 80 ms frames.
      OPUS_FRAMESIZE_100_MS
      Use 100 ms frames.
      OPUS_FRAMESIZE_120_MS
      Use 120 ms frames.

      OPUS_FRAMESIZE_2_5_MS
      Use 2.5 ms frames.
      OPUS_FRAMESIZE_5_MS
      Use 5 ms frames.
      OPUS_FRAMESIZE_10_MS
      Use 10 ms frames.

      Use 120 ms frames.

    • OPUS_SET_PREDICTION_DISABLED

      public static Opus.CTLRequest OPUS_SET_PREDICTION_DISABLED(int value)
      If set to 1, disables almost all use of prediction, making frames almost completely independent. This reduces quality.
      Parameters:
      value - allowed valued:
      0
      Enable prediction (default).
      1
      Disable prediction.

      Prediction disabled.

    • OPUS_SET_DRED_DURATION_REQUEST

      public static Opus.CTLRequest OPUS_SET_DRED_DURATION_REQUEST(int value)
      If non-zero, enables Deep Redundancy (DRED) and use the specified maximum number of 10-ms redundant frames.

    • OPUS_GET_DRED_DURATION_REQUEST

      public static Opus.CTLRequest OPUS_GET_DRED_DURATION_REQUEST(IntBuffer value)
      Gets the encoder's configured Deep Redundancy (DRED) maximum number of frames.

    • OPUS_SET_DNN_BLOB_REQUEST

      public static Opus.CTLRequest OPUS_SET_DNN_BLOB_REQUEST(ByteBuffer data, int len)
      Provide external DNN weights from binary object (only when explicitly built without the weights).

    • OPUS_GET_FINAL_RANGE

      public static Opus.CTLRequest OPUS_GET_FINAL_RANGE(IntBuffer value)
      Gets the final state of the codec's entropy coder.

      This is used for testing purposes. The encoder and decoder state should be identical after coding a payload (assuming no data corruption or software bugs).

      Returns:
      entropy coder state

    • OPUS_GET_SAMPLE_RATE

      public static Opus.CTLRequest OPUS_GET_SAMPLE_RATE(IntBuffer value)
      Gets the sampling rate the encoder or decoder was initialized with.

      This simply returns the Fs value passed to opus_encoder_init(long, int, int, int) or opus_decoder_init(long, int, int).

      Returns:
      sampling rate of encoder or decoder.

    • OPUS_SET_PHASE_INVERSION_DISABLED

      public static Opus.CTLRequest OPUS_SET_PHASE_INVERSION_DISABLED(int value)
      If set to 1, disables the use of phase inversion for intensity stereo, improving the quality of mono downmixes, but slightly reducing normal stereo quality.

      Disabling phase inversion in the decoder does not comply with RFC 6716, although it does not cause any interoperability issue and is expected to become part of the Opus standard once RFC 6716 is updated by draft-ietf-codec-opus-update.

      Parameters:
      value - allowed valued:
      0
      Enable phase inversion (default).
      1
      Disable phase inversion.

    • OPUS_GET_PHASE_INVERSION_DISABLED

      public static Opus.CTLRequest OPUS_GET_PHASE_INVERSION_DISABLED(IntBuffer value)
      Gets the encoder's configured phase inversion status.
      Returns:
      one of the following values:
      0
      Stereo phase inversion enabled (default).
      1
      Stereo phase inversion disabled.

    • OPUS_GET_IN_DTX

      public static Opus.CTLRequest OPUS_GET_IN_DTX(IntBuffer value)
      Gets the DTX state of the encoder.

      Returns whether the last encoded frame was either a comfort noise update during DTX or not encoded because of DTX.

      Returns:
      one of the following values:
      0
      The encoder is not in DTX.
      1
      The encoder is in DTX.

    • OPUS_SET_GAIN

      public static Opus.CTLRequest OPUS_SET_GAIN(int value)
      Configures decoder gain adjustment.

      Scales the decoded output by a factor specified in Q8 dB units. This has a maximum range of -32768 to 32767 inclusive, and returns OPUS_BAD_ARG otherwise. The default is zero indicating no adjustment. This setting survives decoder reset.

      gain = pow(10, x/(20.0*256))

      Parameters:
      value - amount to scale PCM signal by in Q8 dB units.

    • OPUS_GET_GAIN

      public static Opus.CTLRequest OPUS_GET_GAIN(IntBuffer value)
      Gets the decoder's configured gain adjustment.
      Returns:
      amount to scale PCM signal by in Q8 dB units.

    • OPUS_GET_LAST_PACKET_DURATION

      public static Opus.CTLRequest OPUS_GET_LAST_PACKET_DURATION(IntBuffer value)
      Gets the duration (in samples) of the last packet successfully decoded or concealed.
      Returns:
      number of samples (at current sampling rate).

    • OPUS_GET_PITCH

      public static Opus.CTLRequest OPUS_GET_PITCH(IntBuffer value)
      Gets the pitch of the last decoded frame, if available.

      This can be used for any post-processing algorithm requiring the use of pitch, e.g. time stretching/shortening. If the last frame was not voiced, or if the pitch was not coded in the frame, then zero is returned.

      This CTL is only implemented for decoder instances.

      Returns:
      pitch period at 48 kHz (or 0 if not available)
