Abstract
Systems, including methods and apparatus, for applying audio effects to a non-ambient signal, based at least in part on information received in an ambient audio signal. Exemplary effects that can be applied using the present teachings include generation of harmony notes, pitch-correction of melody notes, and tempo-based effects that rely on beat detection.
Claims20
An audio effect processing system, comprising:
- an input mechanism configured to receive a non-ambient audio signal;
- a microphone configured to receive an ambient audio signal;
- and
- a digital signal processor configured to apply an audio effect to the non-ambient audio signal based at least partially upon the ambient audio signal, and to create an output audio signal incorporating the audio effect.

A system for generating musical effects, comprising:
- an input mechanism configured to receive a non-ambient input audio signal;
- a microphone configured to receive an ambient input audio signal;
- a digital signal processor configured to identify a current melody note within the non-ambient input audio signal, to identify a current musical chord within the ambient input audio signal, and to determine a harmony note based at least partially on the current melody note and the current musical chord;
- and
- an output mechanism configured to provide an output audio signal including the current melody note and the harmony note.
2 more elements
A system for generating musical harmony notes, comprising:
- an input mechanism configured to receive a non-ambient audio signal including melody notes;
- a microphone configured to receive an ambient audio signal including accompaniment notes;
- and
- a digital signal processor configured to identify the melody notes, to identify a musical key associated with the accompaniment notes, to produce modified melody notes that have been shifted into the musical key of the accompaniment notes, and to produce an output audio signal including the modified melody notes.
