I know the question What Resources Are Recommended for an Introduction to Signal Processing (DSP)? and I have already read some general DSP books, such as Rick Lyons’s “Understanding DSP,” and also have browsed through Oppenheim’s.

More specifically, **what (printed) book would you recommend for denoising techniques** in general?

Including techniques adapted for audio, spectral subtraction, Wiener filtering, etc. and if possible adapted to *discrete* signal processing with an algorithm/engineering point of view

(i.e. rather `x[k]`

than continuous `x(t)`

and integrals…)

I just ordered a used version of *Advanced digital signal processing and noise reduction*, Vaseghi, but I’m looking for other recommendations.
