opus_projection_ambisonics_encoder_create method

Pointer<OpusProjectionEncoder> opus_projection_ambisonics_encoder_create(
  1. int Fs,
  2. int channels,
  3. int mapping_family,
  4. Pointer<Int32> streams,
  5. Pointer<Int32> coupled_streams,
  6. int application,
  7. Pointer<Int32> error,
)

Allocates and initializes a projection encoder state. Call opus_projection_encoder_destroy() to release this object when finished. @param Fs opus_int32: Sampling rate of the input signal (in Hz). This must be one of 8000, 12000, 16000, 24000, or 48000. @param channels int: Number of channels in the input signal. This must be at most 255. It may be greater than the number of coded channels (streams + coupled_streams). @param mapping_family int: The mapping family to use for selecting the appropriate projection. @paramout streams int *: The total number of streams that will be encoded from the input. @paramout coupled_streams int *: Number of coupled (2 channel) streams that will be encoded from the input. @param application int: The target encoder application. This must be one of the following:

#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.
@param[out] error int *: Returns #OPUS_OK on success, or an error code (see @ref opus_errorcodes) on failure.
