Abstract: Individual adjustment of audio volume and video properties in a computer network conference environment is provided. For audio adjustment, a buffer collects incoming streams; a stream decoder decodes the buffered audio streams, a gain adjustment applies a gain increase or decrease to the individual audio stream, and a mixer combines each of the individual signals together. The gain adjustment module receives input from a user interface control associated with each participant, and adjusts the volume of that participant's stream accordingly. If a requested increase in gain would cause an overflow of the signal, only a gain increase that will avoid such overflow is applied. Video properties such as brightness, contrast and saturation are also adjustable. Properties of the user's transmitted audio and video streams are also adjustable.

Abstract: The invention includes a method, apparatus, and computer program to selectively suppress wind noise while preserving narrow-band signals in acoustic data. Sound from one or several microphones is digitized into binary data. A time-frequency transform is applied to the data to produce a series of spectra. The spectra are analyzed to detect the presence of wind noise and narrow band signals. Wind noise is selectively suppressed while preserving the narrow band signals. The narrow band signal is interpolated through the times and frequencies when it is masked by the wind noise. A time series is then synthesized from the signal spectral estimate that can be listened to. This invention overcomes prior art limitations that require more than one microphone and an independent measurement of wind speed. Its application results in good-quality speech from data severely degraded by wind noise.

Abstract: Power reduction through clock management techniques are disclosed. In one aspect, the clock management is applied to a clock signal on a SOUNDWIRE™ communication bus. In particular, a control system associated with a master device on the communication bus may evaluate frequency requirements of audio streams on the communication bus and select a lowest possible clock frequency that meets the frequency requirements. Lower clock frequencies result in fewer clock transitions and result in a net power saving relative to higher clock frequencies. In the event of a clock frequency change, the master device communicates the clock frequency that will be used prospectively to slave devices on the communication bus, and all devices transition to the new frequency at the same frame boundary. In addition to the power savings, exemplary aspects of the present disclosure do not impact an active audio stream.

The device may create a state of the media data specifying the type of media processing. The device may communicate the state of the media data and an output version of the media data to a recipient device in the media processing chain, for the purpose of supporting the recipient device's adaptive processing of the media data.
