BufferAllocReadChannel

The /b_allocReadChannel message tells the server to allocate memory for a buffer and read in a portion of an audio-file, selecting a subset of its channels. The number of channels is given by the size of the channels argument, and the sample-rate of the buffer is determined by the audio-file.

id: the identifier to use for the buffer. It must denote a currently un-allocated buffer and be greater than or equal to zero and less than the maximum number of buffers.
path: the path of the audio-file to read. Since the server is an independent process, this must resolve with respect to the server's current working directory. If the server is running on a remote node, the path will be resolved in the server's local file system.
startFrame: the offset in frames into the audio-file to begin reading from
numFrames: the number of frames to read which will be the size of the allocated buffer. The special value of -1 denotes that the number of frames available in the file from the given offset is used (the entire file will be read).
channels: a sequence of channel indices to read. Zero corresponds to the first channel of the file.
