I want to know the answer to the following question:
A large benefit of a bit reservoir is that you can use it even while encoding what kind of stream?
All the background I'm provided with is that "Layer III audio can also use a "bit reservoir", a partially full frame's ability to hold part of the next frame's audio data, allowing temporary changes in effective bitrate, even in a constant bitrate stream.". Is that enough to answer the question?
Answer: yes
