US 2016/0079947 A1 · MULTIBAND DUCKER

Abstract

A multiband ducker is configured to duck a specific range of frequencies within a music signal in proportion to a corresponding range of frequencies within a speech signal, and then combine the ducked music signal with the speech signal for output to a user. In doing so, the multiband ducker separates the music signal into different frequency ranges, which may include low, middle, and high-range frequencies. The multiband ducker then reduces the amplitude of the specific range of frequencies found in the speech signal, typically the mid-range frequencies. When the ducked music signal and the speech signal are combined, the resultant signal includes important frequencies of the original music signal, including low-range and high-range, thereby allowing perception of the music signal to continue in relatively uninterrupted fashion. Additionally, the combined signal also includes the speech signal, allowing for the perception of intelligible speech concordant with the perception of music.

Dependent claims

A method for generating an audio signal, the method comprising:

receiving a first signal associated with a first frequency range;
receiving a second signal associated with a second frequency range;
adjusting an amplitude associated with the second signal and corresponding to the second frequency range in inverse proportion to an amplitude associated with the first signal and corresponding to the first frequency range to generate an adjusted second signal;
combining the first signal with the adjusted second signal to generate a combined signal;
and
causing an output device to output the combined signal.
