Abstract
A first device obtains first audio from one or more microphones. The first device generates a first audio signal from the first audio. The first device analyzes the first audio signal to determine noise associated with the first audio. The first device receives a second audio signal from a second device, and processes the second audio signal based at least in part on the determined noise by identifying one or more frequencies of the second audio signal that are between 1-2 Kilohertz. The first device then outputs a modified second audio signal to a speaker.
Claims20
A method comprising:
- obtaining, by a first device, first audio from one or more microphones;
- generating, by the first device, a first audio signal from the first audio;
- analyzing the first audio signal to determine noise associated with the first audio;
- receiving, by the first device, a second audio signal from a second device, the second audio signal not including the noise;
- processing, by the first device, the second audio signal based at least in part on the noise, wherein processing the second audio signal comprises spectrally shaping the second audio signal by identifying one or more frequencies of the second audio signal that are between 1-2 kilohertz based on the noise and increasing a gain for the one or more frequencies;
- and
- outputting a modified second audio signal to a speaker of the first device.
A non-transitory computer readable storage medium having instructions that, when executed by a first device, cause the first device to perform operations comprising:
- receiving first audio by one or more microphones of the first device and generating a first audio signal from the first audio;
- analyzing, by the first device, the first audio signal to determine noise information associated with the first audio;
- receiving a second audio signal from a second device not physically connected to the first device, the second audio signal not including the noise information;
- and
- processing, by the first device, the second audio signal based at least in part on the determined noise information, wherein processing the second audio signal comprises spectrally shaping the second audio signal by identifying one or more frequencies of the second audio signal that are between 1-2 kilohertz based on the determined noise and increasing a gain for the one or more frequencies.
A first device comprising:
- one or more microphones to receive first audio and generate a corresponding first audio signal;
- a receiver, to receive a second audio signal from a second device via a network connection;
- a processing device, coupled to the receiver, to:
- analyze the first audio signal to determine noise information associated with the first audio;
- and
- process the second audio signal based at least in part on the determined noise information, wherein processing the second audio signal comprises spectrally shaping the second audio signal by identifying one or more frequencies of the second audio signal that are between 1-2 kilohertz based on the determined noise and increasing a gain for the one or more frequencies;
- and
- a speaker, coupled to the processing device, to output the processed second audio signal.
