  • Publication number: 20130003991
    Abstract: Disclosed is a system and method of adjusting a volume level for an audio signal for a communication device to comply with a quality threshold. The method comprises: monitoring for an increase in the volume level; and upon determining that implementing the increase in the volume level would produce an output that would exceed the audio frequency pass mask, processing a digitized signal value of the audio signal to produce a first output signal value for the audio signal implementing the increase in the volume level utilizing a digital signal processing (DSP) device in the communication device, a processing filter defined in the digital signal processing device, a first set of adjustment parameters and the digitized signal value.

  • Patent number: 8300848
    Abstract: Disclosed is a system and method of adjusting a volume level for an audio signal for a communication device to comply with a quality threshold. The method comprises: obtaining a digitized signal value of the audio signal and monitoring for an increase in the volume level. In the method, upon determining that implementing the increase in the volume level would produce an output that would exceed the quality threshold, processing the signal value to produce a first output signal value for the audio signal utilizing a digital signal processing (DSP) device in the communication device, a processing filter defined in the digital signal processing device, a first set of adjustment parameters and the signal value.

  • Patent number: 7574010
    Abstract: Disclosed is a system and method of adjusting an audio signal for a communication device. The method comprises: identifying a characteristic associated with the signal and identifying its quality threshold; identifying a first set of adjustment parameters for the signal when the threshold is exceeded; and identifying a second set of adjustment parameters when it is not exceeded. Also, the device: monitors for a current setting value for the characteristic; and detects whether the current setting value is above or below the quality threshold. If the value is above, then the device produces a first output signal value utilizing a DSP, a processing filter defined in the DSP, values of the first set of adjustment parameters and the signal value. If the value is below, the device produces a second output signal value utilizing the DSP, the filter, values of the second set of adjustment parameters and the signal value.
