PartyAudioManipulationSourceStream::GetNextBuffer

  • Article

Gets the next buffer available in the stream.

Syntax

PartyError GetNextBuffer(  
    PartyMutableDataBuffer* buffer  
)

Parameters

buffer   PartyMutableDataBuffer*
output

The output buffer. If no buffer is available, the PartyMutableDataBuffer's bufferByteCount field is 0, and its buffer field is nullptr.

Return value

PartyError

c_partyErrorSuccess if the call succeeded or an error code otherwise. The human-readable form of the error code can be retrieved via PartyManager::GetErrorMessage().

Remarks

When voice activity is detected, a new buffer is available every 40 ms. Otherwise, no buffers are available. Buffers retrieved by this method must be returned to the library via PartyAudioManipulationSourceStream::ReturnBuffer() when they're done being used.

The total number of buffers instantaneously available can be retrieved via PartyAudioManipulationSourceStream::GetAvailableBufferCount(). Multiple buffers can be retrieved in succession before any are returned.

Each buffer is in the format specified by PartyAudioManipulationSourceStream::GetFormat().

A mutable data buffer is provided so that the app can optionally modify the audio in place.
