Abstract
The present invention includes methods, circuits, devices, systems and associated computer executable code for acquiring, processing and rendering acoustic signals. According to some embodiments, one or more direction specific audio signals may be generated using a microphone array comprising two or more microphones and an audio stream generator. The audio stream generator may receive a direction parameter from an optical tracking system. There may be provided an audio rendering system adapted to normalize and/or balance acoustic signals acquired from a soundscape.
Claims24
An audio acquisition device comprising:
- a microphone array comprising two or more microphones positioned some distance from one another, wherein each of said microphones is adapted to convert acoustic signals into electrical signals;
- a directional audio stream generator (DASG) adapted to convert electric signals output by one or more of said microphones into a first direction specific audio signal corresponding to acoustic signals having a first direction of arrival;
- and
- a tracking system comprising:
- (a) a sensor configured to detect electromagnetic energy reflected from a sound source;
- and (b) signal processing circuits to process signals generated said sensor responsive to detection, wherein said tracking system is adapted to:
- (i) identify at least one feature of a sound source within a field of coverage of said sensor, (ii) estimate a relative direction of the sound source, and (iii) generate at least one direction parameter used by said DASG to generate the first direction specific audio signal.
