An audio system with a base station connected to multiple mobile devices. The base station and the mobile devices are configured to exchange data. The base station is connected to an audio mixer configured to receive multiple input signals from the mobile devices, mix them into a single signal, and provide it as an in-ear monitoring signal. This signal is then transmitted to a mobile device that includes an output amplifier and connected transducers. The mobile device receiving the in-ear monitoring signal has a volume control that allows the user to adjust the playback volume of the in-ear monitoring signal. The mobile device also has an audio compressor that compresses the input signal level of the in-ear monitoring signal as a function of the volume setting, ensuring that the output level of the output amplifier does not exceed a predefined limit.

A voice capture system including a first and second voice beamformer, a voice mixer, a voice rejected noise beamformer, a noise beamformer adjustor, a jammer suppressor, and a speech enhancer is provided. The first and second voice beamformer and the voice mixer generate a voice enhanced reference signal based on a first and second frequency domain microphone signal. The voice rejected noise beamformer includes filter weights and generates a noise reference signal based on the first and second frequency domain microphone signal. The noise beamformer adjustor adjusts the one or more filter weights of the voice rejected noise beamformer to account for fit variation. The jammer suppressor generates a jammer suppressed signal based on the voice enhanced reference signal and the noise reference signal. The speech enhancer dynamically generates an output voice signal by applying a dynamic noise suppression signal to each frequency bin of the jammer suppressed signal.

Systems and methods for routing audio and / or video streams and remote rendered video layout for conference side group conversations and voice assistant providers are disclosed. During a main conference comprising a plurality of users, a request is received to create a side group conversation comprising a subgroup of the plurality of users. A voice assistant provider is invited to the side group conversation. Users in the subgroup may be granted different permissions to query or receive responses from the voice assistant. Incoming audio and video streams from each user are demultiplexed and decoded. Decoded audio streams are processed by an appropriate audio mixer of the group and voice assistant. Decoded video streams are processed and rendered based on a video grouping render policies. Processed audio streams for each group and voice assistant and / or rendered videos are encoded and routed to each user through their dedicated multiplexer.
