Abstract
An audio processor generates a vocal-free audio signal from an audio signal received from an audio source, directs a cross-fader to fade from the audio signal to the vocal-free audio signal responsive to occurrence of a trigger condition indicated by a status signal, and directs the cross-fader to fade from the vocal-free audio signal to the audio signal responsive to the trigger condition no longer being present.
Claims20
A system comprising:
- an audio processor programmed to
- generate a vocal-free audio signal from an audio signal received from an audio source by removing vocal energy from the audio signal,
- direct a cross-fader to fade from the audio signal to the vocal-free audio signal responsive to occurrence of a trigger condition indicated by a status signal, the trigger condition indicating that a prompt including vocal content is to be provided,
- provide the prompt summed to the vocal-free audio signal for playback, and
- direct the cross-fader to fade from the vocal-free audio signal to the audio signal responsive to the trigger condition no longer being present.

A non-transitory computer-readable medium comprising instructions that, when executed by an audio processor, cause the audio processor to:
- generate a vocal-free audio signal from an audio signal received from an audio source by removing vocal energy from the audio signal;
- direct a cross-fader to fade from the audio signal to the vocal-free audio signal responsive to occurrence of a trigger condition indicated by a status signal, the trigger condition indicating that a prompt including vocal content is to be provided;
- provide the prompt summed to the vocal-free audio signal for playback;
- and
- direct the cross-fader to fade from the vocal-free audio signal to the audio signal responsive to trigger condition no longer being present.
