CELT allows for bitrate adjustment in one byte per frame
increments without any signaling requirement or overhead.
Applications SHOULD utilize congestion control to regulate the transmitted bitrate.
+In some applications it may make sense to increase the packetization
+interval rather than decreasing the codec bitrate. Congestion control
+implementations should consider the users differential tolerance for high
+latency and low quality.
