Limiting distortion of acoustic rendering

A frequency-dependent signal limiter using a paired combination of a bandpass filter (or "selection filter") and an attenuating equalizing filter (or "cutting filter") limit the amount of distortion generated by an audio output device in an acoustic rendering system. A bank of on...

Beschreibung
Zusammenfassung:	A frequency-dependent signal limiter using a paired combination of a bandpass filter (or "selection filter") and an attenuating equalizing filter (or "cutting filter") limit the amount of distortion generated by an audio output device in an acoustic rendering system. A bank of one or more of these pairs in series can be used to limit selected frequencies identified as primary causes of distortion in the audio output device to specified levels that avoid distortion.
