With a lot of help in the forum thread you mentioned, I did a rather large project with fft_real() - including a spectrum analyzer view - and it does work as expected.

I'm pretty sure you're getting different values with some offsets because the FFT buffer crosses the 65536 boundary (per the documentation you quoted).

Try adding this line immediately above the loop() that prints the results:

((in_buf/65536)|0) != (((in_buf+fft_size*(real?1:2) - 1)/65536)|0) ? gfx_printf("would give bad results\n") :

(that will print an error message rather than results if in_buf crosses a boundary)

really quite nice Veto... thanks

Looks perfect !

Any chance you provide it via ReaPack (please including a decent "About" section) ?

Thanks a lot !

Interesting ! This is an ambitious project !

It could have been nice to have a toggle for having tracks colors instead of predetermined one but it's not possible via JSFX to get track color...

... but what is possible to add JSFX sliders for INT colors of each tracks, and altered this with a script (scripts can set FX values), like "Set Veto's freq analyser JSFX color to their track receive" (I assume you put the analyses on a dedicated analyzing group). :P

More complex but very useful would be to have a Slope settings, like there is on Voxengo Span.


As you can see the GFX version looks more 'bassy' than the voxengo one. (in fact it is pretty harsh electric guitar signal, Span slope gives me a more accurate (to what I hear) analyses by showing this bump in the highs.

Thanks for your work !

I agree with X-Raym to be able to customize the colors
Slope would be nice too.
Very cool Veto!

Yes.
A common setting (which I also use) is a slope of 3dB/octave so that pink noise shows flat.
Span uses 4.5dB/octave as default.

Nice work on the analyzer btw.

It should be included into Reaper installer.
Nice plug-in! Thank you for the good job!

[mschnell]

As already stated I would appreciate buttons to set the slope to zero and to pink noise compensation (I don't remember the value for that)

Very, very cool!! Thanks a lot!

With regards to Span - I had always the feeling that it shows something to me that wasn't really helpful..

I mean...how can you get used to a curve when you always have to adjust the slope/tilt to make it show different signal levels every time?
Is it really useful to adjust something to show you what you wanna see instead of adjust the sound to make the given analyzer show what is "real"?

Would something like iZotope's Balance Control or Hofa IQ-Analyzer or anything simliar really be of good reference help it you don't know what the analyzer is currently showing because you always have to check and adjust the slope for that special task that you're observing?

I personally need one Reference to which I can get used to where I see directly if my sound curve is within the ballpark or not..

Thanks again Veto for that great mod!!

For me that greatest feature you may want to take into account is the ability to load and save reference curves and maybe to show a weighted curve in addition to the peaks like the great IQ-Analyzer does with its Energy Curve :-)

While I think that slope is important, at least two slope setting (flat and "pink noise") should be available by direct buttons.

Many thanks Veto!!
