Reply To: Noise shaped dither – Does it cause issues with DSP-based volume controls?

    Bob Olhsson: Good question….  What Alex discovered (and which I’m working on demonstrating in a power point using his research) is that the original random noise in the original noise shaped dithered source helps to modulate and disguise the distortion due to truncation in the DSP processor. It’s not “self-dither” but it does help. So, in other words, noise shaped dither helps deal with defective (undithered) digital monitor controls. It’s not a solution, but it is a kind of bandaid.

    Therefore, equalization, compression, crossovers, I think any kind of processing common in consumer A/V receivers, will be helped by noise shaped sources.

    I’m sure Alex will elaborate here on this discovery and his thoughts on the matter.
