Abstract
An apparatus including circuitry configured to: obtain at least two audio signals; determine, with respect to the at least two audio signals, an audio object part and an ambience audio part; determine a level parameter based on the ambience audio part; apply a noise suppression to the audio object part, wherein the noise suppression is configured to be controlled based on the determined level parameter; and generate a noise suppressed audio object part based on the applied noise suppression.
Claims20
An apparatus comprising:
- at least one processor;
- and
- at least one memory storing instructions that, when executed with the at least one processor, cause the apparatus to:
- obtain at least two audio signals;
- determine, with respect to the at least two audio signals, an audio object part and an ambience audio part;
- determine a level parameter based, at least partially, on the ambience audio part and the audio object part;
- apply a noise suppression to the audio object part, wherein the noise suppression is configured to be controlled based on the determined level parameter;
- and
- generate a noise suppressed audio object part based on the applied noise suppression and the audio object part.
A method comprising:
- obtaining at least two audio signals;
- determining, with respect to the at least two audio signals, an audio object part and an ambience audio part;
- determining a level parameter based, at least partially, on the ambience audio part and the audio object part;
- applying a noise suppression to the audio object part, wherein the noise suppression is configured to be controlled based on the determined level parameter;
- and
- generating a noise suppressed audio object part based on the applied noise suppression and the audio object part.
A non-transitory computer-readable medium comprising program instructions stored thereon for performing at least the following:
- obtain at least two audio signals;
- determine, with respect to the at least two audio signals, an audio object part and an ambience audio part;
- determine a level parameter based, at least partially, on the ambience audio part and the audio object part;
- apply a noise suppression to the audio object part, wherein the noise suppression is configured to be controlled based on the determined level parameter;
- and
- generate a noise suppressed audio object part based on the applied noise suppression and the audio object part.
