capture_file()

BufferOperation MayaFlux::Kriya::BufferOperation::capture_file ( const std::shared_ptr< IO::IOManager > &  io_manager, const std::string &  filepath, uint32_t  channel = 0, uint32_t  cycle_count = 0  )

static

Create a file capture operation that reads from file and stores in stream.

Parameters

io_manager	IOManager for file loading
filepath	Path to audio file
channel	Channel index (default: 0)
cycle_count	Number of cycles to capture (0 = continuous)

Returns

BufferOperation configured for file capture
