摘要： Systems and methods for a headset adapter circuit are disclosed. The headset adapter circuit generally includes a maximal length sequence generator circuit coupled to the adapter transmit signal line for injecting a maximal length sequence signal. A maximal length sequence cross-correlator circuit is coupled to the adapter receive signal line for capturing a receive signal sample and convolving the receive signal sample with the maximal length sequence signal to generate a host phone sidetone path impulse response.

摘要： The present invention provides an echo reduction apparatus, system, and method that advantageously reduces echo when communicating over packet-switched networks. An echo reduction apparatus, including echo reduction circuit, operably couples a headset or handset device to an audio source that is capable of transmitting a sound signal. The echo reduction circuit receives the sound signal from the audio source and a transmit signal from the headset or handset device and provides an adjusted sound signal to the audio source. Advantageously, a variety of headsets and handsets may be used in accordance with the present invention with reduced caller echo and without the need to purchase new headsets or handsets.

摘要： A method of enhancing the intelligibility of speech sounds in a communications headset, includes: detecting an incoming signal with speech content; based upon detectable parameters in the incoming signal, determining a combination of signal processing parameters including a high pass cutoff frequency value and a low pass cutoff frequency value for a filtering function, and an expander threshold level, an expander attack time, and an expander release time for an expander function; and sequentially applying the filtering function and expander function to the incoming signal so that the degraded sound quality of the incoming signal may be modified real-time to increase intelligibility as variations occur in speech sound quality of the incoming signal.

摘要： Sound pressure level limiter with anti-startle feature for audio systems are disclosed. The anti-startle feature may be implemented with a delta incident detector for detecting delta acoustic incidents that exceed a predetermined acoustic startle boundary, a delta limiter for determining an anti-startle gain, and an amplifier to apply the anti-startle gain to the input signal. The delta incident detector may detect delta incidents based on an estimated true SPL delivered by a transducer to a predetermined datum point. The estimated true SPL may be determined by based on a measured receiving frequency response of the transducer. An SPL limiter may also determine an SPL gain in response to detecting an SPL acoustic incident that exceeds a predetermined SPL threshold, and an amplifier may apply the SPL gain to the input signal to reduce it below the threshold.
