Re: Clear Sound Quality Techniques........questioning equipm

The first thing I'm questioning is are all parts of any computer already automatically supporting clear sound quality? The inside of a computer is a hostile environment for audio. All of the electronics produce electrical "noise" which can leak through into the analog components of the so...

Re: noise reduction in 2.1.1 version

The Noise Reduction effect in 2.1.1 is the same as in 2.1.0. It is likely to also be the same in 2.1.2 though the default settings may be tweaked a little. The current defaults has "Frequency smoothing" at zero, but reports indicate that a higher value will often give slightly better resul...

Re: Waveform antialiasing

How many - two votes? I think this has also been asked for before a couple of times by others. I think I might have voted against it last time round (due to concerns about speed). I'm now in favour if it can be drawn efficiently enough to not impact on audio performance (which I suspect it can, but...

As Gale said.
The max duration is about 10 million samples.

Re: Shaded waveform view (when zoomed out)

Each "band" goes down/up to the DC offset and the "bands" are added up on the z-axis. How are you measuring "DC offset"? I thought that you were taking the mean of samples within each pixel width, but if that is the case you cannot determine that it is "DC offset&...

Re: Shaded waveform view (when zoomed out)

Pretend we released this as an alternative waveform that does not show RMS. How would the one sentence in the release notes describe it, so that anyone would want to use it? Say in another sentence - does the top of a pixel width ever show values above the peak? Say in another sentence - if a zoome...

Re: Static Noise (T Bone SC 440) Please help me :)

Here is a short sound test where i am talking loud (without audition and vac) firsttrack012.png As you can see, the waveform is now slamming into the top and bottom of the track, causing the waveform to be "clipped". If I amplify the waveform by a small negative amount and then zoom in ve...

Re: Shaded waveform view (when zoomed out)

First, I wan't to add some more to the first post. Please don't change the content of older posts after there has been a reply. It is very confusing to do so. Fixing spelling errors is of course OK, but if the content is changed then that demands that everyone engaged in the topic has to re-read th...

Re: Waveform antialiasing

Now that we have a fresh proposal, I think yes.
There may be some votes to count for drawing zoomed in samples with a curved line joining the dots (sinc interpolation) rather than straight lines (linear interpolation).

Re: Numeric text input widget for Nyquist plug-ins

The only thing I would change: take a somewhat catchier name, without dashes, like - intbox - floatbox - realbox Thanks for the suggestion. I'm not overly keen on the names either, but this was my reasoning: If it were C++ we would almost certainly CamelCase it as one compound word, but Nyquist alm...
