+Buffer
+ Inter widget audio data buffer within a DSP.
+Scheduler
+ DSP internal scheduler that schedules component/pipeline processing
+ work.
+Effect
+ Widget that performs an audio processing effect.
+SRC
+ Sample Rate Converter within DSP or CODEC
+ASRC
+ Asynchronous Sample Rate Converter within DSP or CODEC
+Encoder
+ Widget that encodes audio data from one format (usually PCM) to another
+ usually more compressed format.
+Decoder
+ Widget that decodes audio data from a compressed format to an
+ uncompressed format like PCM.
