Abstract
A method and apparatus comprising computer code configured to cause a processor or processors to receive multiple audio signals obtained from ones of a plurality of microphones of a microphone array, implement an audio zooming based on the audio signals by selectively focusing and enhancing first ones of the audio signals and by attenuating other ones of the audio signals, and control an output of audio based on the audio zooming, and the audio zooming includes a consolidating of a plurality of directional features of the first ones of the audio signals within a field around the microphone array and a countering based on determining directional aspects of the other ones of the audio signals from outside of the field.
Claims20
A method of audio processing, the method performed by at least one processor and comprising:
- receiving multiple audio signals obtained from ones of a plurality of microphones of a microphone array;
- implementing an audio zooming based on the audio signals by selectively focusing and enhancing first ones of the audio signals and by attenuating other ones of the audio signals;
- and
- controlling an output of audio based on the audio zooming,
- wherein the audio zooming comprises a consolidating of a plurality of directional features including first frequency bands of the first ones of the audio signals within a field around the microphone array and a countering based on determining directional aspects including second frequency bands of the other ones of the audio signals from outside of the field.
An apparatus for audio processing, the apparatus comprising:
- at least one memory configured to store computer program code;
- at least one processor configured to access the computer program code and operate as instructed by the computer program code, the computer program code including:
- receiving code configured to cause the at least one processor to receive multiple audio signals obtained from ones of a plurality of microphones of a microphone array;
- implementing code configured to cause the at least one processor to implement an audio zooming based on the audio signals by selectively focusing and enhancing first ones of the audio signals and by attenuating other ones of the audio signals;
- and
- controlling code configured to cause the at least one processor to control an output of audio based on the audio zooming,
- wherein the audio zooming comprises a consolidating of a plurality of directional features including first frequency bands of the first ones of the audio signals within a field around the microphone array and a countering based on determining directional aspects including second frequency bands of the other ones of the audio signals from outside of the field.
A non-transitory computer readable medium storing a program causing a computer to:
- receive multiple audio signals obtained from ones of a plurality of microphones of a microphone array;
- implement an audio zooming based on the audio signals by selectively focusing and enhancing first ones of the audio signals and by attenuating other ones of the audio signals;
- and
- control an output of audio based on the audio zooming,
- wherein the audio zooming comprises a consolidating of a plurality of directional features including first frequency bands of the first ones of the audio signals within a field around the microphone array and a countering based on determining directional aspects including second frequency bands of the other ones of the audio signals from outside of the field.
