Abstract
Systems and methods are disclosed for operating a wireless audio network including a plurality of wireless microphone units (e.g., wireless delegate units) and a central access point having a mixer. The wireless microphone units may perform voice detection and level sensing, and make a preliminary gating decision. The central access point may make a final gating decision, determine the granting of wireless communications channels, and generate a final mixed audio output signal.
Claims21
A wireless audio system, comprising:
- a plurality of wireless microphone units each configured to:
- determine a preliminary gating decision at least partially based on a metric associated with an audio input signal;
- and
- wirelessly transmit an access request based on the preliminary gating decision, wherein the access request is for requesting a grant of a wireless communication channel;
- and
- a central access point in wireless communication with the plurality of wireless microphone units, the central access point configured to grant the wireless communication channel for a selected designated wireless microphone unit of the plurality of wireless microphone units, at least partially based on at least one access request received from at least one of the plurality of wireless microphone units.
A method, comprising:
- determining, at each of a plurality of wireless microphone units, a preliminary gating decision at least partially based on a metric associated with an audio input signal;
- wirelessly transmitting, from at least one of the plurality of wireless microphone units to a central access point, an access request based on the preliminary gating decision, wherein the access request is for requesting a grant of a wireless communication channel;
- and
- granting, by the central access point, the wireless communication channel for a selected designated wireless microphone unit of the plurality of wireless microphone units, at least partially based on the access requests received from the plurality of wireless microphone units.
A wireless microphone unit configured to:
- detect an audio input signal;
- determine a metric associated with the audio input signal;
- determine, at least partially based on the metric, a preliminary gating decision;
- and
- responsive to the preliminary gating decision being a positive gating decision, wirelessly transmit an access request to a central access point, the access request for requesting a grant of a wireless communication channel between the wireless microphone unit and the central access point.
