Audacity Forum

I am experimenting with eq-band now. I am filtering white noise and using spectrum analysis to see what the response is like. I thought it was supposed to have a broad, flat floor in the middle, but instead, with two octave width, I see a broad notchy shape. (More gradual than a "notch filter.") I c...

Some questions about Steve's suggestions... Would eq-band be a good choice to implement filtering of selected regions? It has hz, gain, and width parameters which can all be variable. Would it be enough to vary gain only? In the old deesser code you shared with me elsewhere, you used a combination o...

Also the slope function seems always to assign a zero start time, contrary to the documentation, which might matter in other programs, but not in the sound returned to Audacity, which ignores the sound's start anyway and only uses the sample sequence.

You may be losing less signal than you think. If you subtract the original from the modified signal, there may be phase shifts in retained frequencies, giving the false impression that you are subtracting some of the real sound. If original is a sine wave and modified is shifted half a cycle, for in...

Sorry, I must have misread member start dates for posting dates.

I have not read the whole thread from years ago about Trevor's idea of slope, clip, then integrate as a procedure for removing spikes. My first thought is that if the slopes of the two sides of the spike are not equal in absolute value, then a dc offset is introduced, until the next spike where the ...

waxcylinder, I made some improvement of progress bar behavior between my first and second versions but I know there is more I could do. If there are few or no clicks to detect at any one of the test frequencies, progress will still look erratic during the first half. I do not fully understand how th...

I understand that if my calculations make multiple passes over the sound, communicating intermediate results in lists, then progress will only indicate the first pass and stall during the others. Calling (snd-length s ny:all) early is the simplest example. If instead I reorganize them as interleaved...

How are calculations of my Nyquist script reflected in the progress indicator? How can I make its progress more smooth? I have inferred that progress through the first half reflects what portion of the input sound has been examined at least once. I am not sure how to interpret the other half. Someti...

Tell me too whether the tool worsens the sound more than it improves it.
