In an audio encoder, for audio content received in a source audio format, default gains are generated based on a default dynamic range compression (DRC) curve, and non-default gains are generated for a non-default gain profile. Based on the default gains and non-default gains, differential gains are generated. An audio signal comprising the audio content, the default DRC curve, and differential gains is generated. In an audio decoder, the default DRC curve and the differential gains are identified from the audio signal. Default gains are re-generated based on the default DRC curve. Based on the combination of the re-generated default gains and the differential gains, operations are performed on the audio content extracted from the audio signal.

An audio hub is disclosed including a plurality of daughterboards and a mainboard communicatively coupled to each of the plurality of daughterboards. Each of the plurality of daughterboards is associated with an audio channel and each audio channel is independent from the other of the audio channels associated with the other ones of the plurality of daughter boards. Further, each daughterboard includes at least one wireless transceiver operably configured to wirelessly transmit an audio signal associated with the corresponding audio channel from a musical instrument over a network to the audio playback device. The mainboard is configured so that, for each of the plurality of daughterboards, the mainboard is operable to independently modify at least one characteristic of the audio signal from the musical instrument before the audio signal is transmitted to the audio playback device.
