  • Applications for a two-way wireless speaker system
    Patent number: 9078058
    Abstract: The two-way wireless speaker system of this invention increases sound fidelity by enabling speakers to acknowledge receipt of audio data packets. This provides increased functionality because the audio hub can receive data not only from wired inputs, but also wireless transmission from computer, cell phone, and other sources. Audio hub can use information from speaker to customize/adjust audio signal for each speaker independently, giving better audio quality and synchronization among speakers.

  • Multi-stream audio level controller
    Patent number: 8724830
    Abstract: A volume level and crossfade controller with programmable fades and audio stream priority controls saturation for a multiple audio stream mixer. Start of fade and end of fade events trigger updates of relative volume level targets and volume ramps.

  • Beat Matching for Portable Audio
    Publication number: 20100251877
    Abstract: Beat matching for two audio streams extracts beats from each, computes a conversion ratio from one stream to the other stream by an initial beat alignment plus a stability-maintaining beat alignment. A variable resampling converter or time scale modifier adjusts one stream to align beats with those of the other (reference) stream. Thus for cross-fading two music streams the beats of the fading-in stream can be matched to those of the fading-out stream for a seamless transition.
