/// Parameter `inNumberOfFrames`: The number of frames required to complete the request. You may supply either these many
/// frames or none.

/// Returns: An AudioBufferList containing data to be rendered, or null if no data is available.
/// The data in the returned buffer must not be cleared or re-filled until the input block is
/// called again or the rendering has finished.
/// The format of the returned buffer must match the format specified when registering the

/// If you are out of data and return null or less than the requested number of frames, this

/// context. Care should be taken not to make any blocking call (e.g. calling libdispatch,
/// blocking on a mutex, allocating memory etc.) which may cause an overload at the lower layers.
