Detailed Description

Base class for all acwriter_t's.

This class decouples signal processing from writing to disk. There's one acwriter per AC variable to be written to disk. Each instance of acwriter spawns its own writer thread and has its own internal FIFO to safely move the samples of the AC variable out of the processing thread. All acwriters share an output file. It's not problematic when an acwriter has to wait for write access because the waiting does happen in its own thread, not in the audio thread.
