For mirophone, both single ended inputs and differential oputs are supporied. ‘To maintain a high quality signal, a stable biss voltage source to the condenser miczophone‘s FET is provided. The DC blocking capacitors can be used at both positive and negative sides ofa input. Iternally, this analog nignal is converied to 16—bit, 8/16 kz linear PCM data. 2.1 Digital Signal Procemsor ‘A Digital Signal Processor (DSP) is used to perform speech and muiio procersing. The advanced epeech features, sich ss scoustic echo cancellation and noise reduction are inbuilt. To reduce noulinear distortion and to help echo cancellation, an outgoing signal level to the speaker is monitored and adjusted to avod saturation ofspeaker output or microphone input. Adspive ftering is also applied to tack the ocho path impulse in response to provide ocbo five and. fulldoplex user experience, ‘The embedded noisereduction algoritim helps to extract cleen speoch signals from the noiy inputs captured by the 1microphones and improves mutnal understandting in communication. The advanced andlo fetures, such as multi—band dynamic range control, parsmetric mult—band equalizer, sndlo widening and virtual bass are inbullt, The sudio effect algoritims are to improve the user‘s audio listening experience in terms ofbetter audio quality after audio signal processing.
