class BaseConsumerStage

Defined at line 26 of file ../../src/media/audio/services/mixer/mix/base_consumer_stage.h

Base class for consumers. A consumer has one source stream and zero destination streams. All data

"consumed" from the source stream is written to an object that implements the

`BaseConsumerStage::Writer` interface. Data is "consumed" in whole frame units, hence this class

represents frame units with int64_t instead of Fixed.
