Context: 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. Internal handling of the bit reservoir increases encoding delay.[citation needed]

Question: A partially full frame's ability to have part of the next frame's audio data is referred to as what?
Answer: bit reservoir

Question: What kind of audio is required to use a bit reservoir?
Answer: Layer III

Question: A bit reservoir allows for what kind of changes in effective bit rate?
Answer: temporary

Question: What is a possible result of handling the bit reservoir?
Answer: encoding delay

Question: A large benefit of a bit reservoir is that you can use it even while encoding what kind of stream?
Answer: constant bitrate
