Expand description

Identical to AudioConverterFillComplexBuffer, with the addition of a realtime-safety guarantee.

Conversions involving only PCM formats – interleaving, deinterleaving, channel count changes, sample rate conversions – are realtime-safe. Such conversions may use this API in order to obtain compiler checks involving the CA_REALTIME_API attributes.

At runtime, this function returns kAudioConverterErr_OperationNotSupported if the conversion requires non-realtime-safe functionality.

§Safety

  • in_audio_converter must be a valid pointer.
  • in_input_data_proc must be implemented correctly.
  • in_input_data_proc_user_data must be a valid pointer or null.
  • io_output_data_packet_size must be a valid pointer.
  • out_output_data must be a valid pointer.
  • out_packet_description must be a valid pointer or null.
