Abstract: Methods, systems, and devices for wireless communications are described. In a wireless audio system, a first wireless device may generate a first media stream associated with a first media mode and a second media stream associated with a second media mode, buffer the first media stream in accordance with a first latency time value for adjusting a first latency time of the first media stream and buffering the second audio stream, independently from the first media stream, in accordance with a second latency time value for adjusting a second latency time of the second media stream, and transmit a mixed media stream including the buffered first media stream mixed with the buffered second media stream to a second wireless device.

Abstract: In general, techniques are described that enable a source device to perform level estimation for processing audio data. The source device may include a memory and a processor. The memory may store at least a portion of the audio data. The processor may obtain a current indication representative of a current level of a current block of the audio data, and obtain a previous indication representative of a previous level of a previous block of the audio data. The processor may perform, based on the current indication and the previous indication, level estimation to obtain a level estimate indication representative of an estimate of the level of the current block of the audio data. The processor may also perform, based on the level estimate indication, compression with respect to the current block of the audio data to obtain a bitstream.
