Abstract: Systems, devices, and methods for determining and establishing frequency-dependent gain compensation in wide bandwidth communication systems are disclosed. Variable frequency-dependent gain compensation circuits, or variable equalizers, have settings that configure them to establish discrete frequency-dependent gain compensation. The frequency-dependent gain compensation can include various types and levels of gain slope and/or ripple. The settings of the variable equalizers can be set by control signals established a control circuit in response to signals from an external computer. The variable equalizers are coupled to other circuits or devices and the frequency-dependent gain of the combined circuit are measured. The settings of the variable equalizer are then changed to establish an optimal frequency-dependent gain profile or frequency-dependent gain that is closest to a predetermined frequency-dependent target gain profile. The settings can then be saved in a memory or register.

Abstract: A headset, which may be configured to process audio for a player participating in an online multiplayer game, may support auto-pairing with audio basestations. In this regard, an audio basestation may be utilized in communicating game and chat audio content from an associated game console to a paired headset and in communicating microphone audio from the paired headset to the console. The auto-pairing may comprise automatically exchanging signals with an audio basestation, in response to the headset coming within a determined distance of the audio basestation; and pairing with the audio basestation based on processing of the exchanged signals. The pairing may result in establishing one or more wireless links for game and chat audio to be communicated to the headset and microphone audio to be communicated from the headset. The determined distance may correspond to physical contact (e.g., tapping) between the headset and the basestation.
