Is the dnoise utility up to scratch (at least with 'csound64 -U dnoise')?

I am getting a sort of ring-modulated result out of it, even with the 
default settings. I can send some examples if needed.

Best,

Peiman

I guess I should be more specific with my question, has anyone ever use 
this utility with good results? Maybe I need to tweak the settings but I 
can get rid of this buzzing sound in the output file.

Hi,

I haven't looked at it, but you can get good results with the pvs
opcodes. There's an example showing noise reduction in QuteCsound (I
think it's in the miscellaneous category).

Cheers,
Andres

Thanks Andres,

Yes I have also had very good results from the pvs opcodes (inspired by 
the QuteCsound example I went ahead and added an averaging algorithm to 
the noise print). However, it would be much quicker to run it form the 
terminal with dnoise (e.g. for batch processing and all that). But if it 
comes to it I'll write a csd for batch processing.

Best,

Peiman

dnoise was written by Mark Dolson a long time back, and adjusted to
csound5 by me.  I never tested it extensively, and personally i have been
using the dnoise in Audacity and/or GWC

Would be nice to have more reports

Thanks John,

Here is an example

peimankh$ csound64 -U dnoise -A -i "guit 81_selection.wav" -otest.aif 
"guit 81.wav"
PortMIDI real time MIDI plugin for Csound
PortAudio real-time audio module for Csound
virtual_keyboard real time MIDI plugin for Csound
0dBFS level = 32768.0
Csound version 5.13 (double samples) Jan 17 2011
libsndfile-1.0.21
util dnoise:
Infile set to guit 81.wav
audio sr = 96000, stereo, reading both channels
opening WAV infile guit 81.wav
analysing 497965 sample frames (5.2 secs)
audio sr = 96000, stereo, reading both channels
opening WAV infile guit 81_selection.wav
analysing 75307 sample frames (0.8 secs)
writing 22528-byte blks of 24bit ints to test.aif (AIFF)


You can download the results here

It sounds like some sort of windowing discontinuity.

Best,

Peiman
