Abstract
Example embodiments provide a process that includes one or more of receiving an audio signal from a feedback path of a feedback compressor circuit, determining whether an auxiliary attenuation value applied to the feedback compressor circuit has changed since a last audio signal was received, responsive to determining the auxiliary value has changed, determining a current operational state value of the LPF needs to be modified based on the changed auxiliary attenuation value, modifying the operational state value of the LPF, and applying the audio signal to the modified LPF.
Claims20
A method comprising:
- receiving an audio signal from a feedback compressor circuit;
- responsive to determining an auxiliary attenuation value applied to the feedback compressor circuit has changed, determining a current operational state value of a low pass filter (LPF) needs to be modified;
- responsive to determining the auxiliary attenuation value has increased or decreased, changing the operational state value of the LPF by a value that is proportional to the change in the auxiliary attenuation value;
- modifying the current operational state value of the LPF;
- and
- applying the audio signal to the modified LPF.
An apparatus comprising:
- a receiver configured to receive an audio signal from a feedback compressor circuit;
- a processor configured to
- responsive to a determination that an auxiliary attenuation value applied to the feedback compressor circuit has changed, determine a current operational state value of a low pass filter (LPF) needs to be modified;
- responsive to a determination that the auxiliary attenuation value has increased or decreased, change the operational state value of the LPF by a value that is proportional to the change in the auxiliary attenuation value;
- modify the current operational state value of the LPF;
- and
- apply the audio signal to the modified LPF.
A non-transitory computer readable storage medium configured to store instructions that when executed cause a processor to perform:
- receiving an audio signal from a feedback compressor circuit;
- responsive to determining an auxiliary attenuation value applied to the feedback compressor circuit has changed, determining a current operational state value of a low pass filter (LPF) needs to be modified;
- responsive to determining the auxiliary attenuation value has increased or decreased, changing the operational state value of the LPF by a value that is proportional to the change in the auxiliary attenuation value;
- modifying the current operational state value of the LPF;
- and
- applying the audio signal to the modified LPF.
