Abstract
Techniques for frame-based noise reduction and other signal processing techniques are provided that are able to reduce latency below the frame length. This may be accomplished by using an asymmetric trapezoidal (or quasi-trapezoidal) filter. Instead of cross-fading between successive frames taking up half the frame length, the cross-fading between successive frames is reduced to 10-25% of the frame length, for example. This allows the latency to be reduced to 60-75% of the frame length (plus the signal processing time) instead of the full frame length (plus the signal processing time) in prior techniques.
