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 !

[heda]

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.

@Veto

The colors are hard-coded

You can keep this mod, it make sense, especially if you master groups tracks that are not colored, but a toggle allowing custom colors would be nice :P Companion scripts to set this colors from selected tracks or palette or whatever could be made with access to color sliders.

but would result in lesser contrast in any case.

User problem. We can think about a master Saturation slider but this is really low priority I think. Personally, I only use vibrant colors already.
There is some situations where we don't want contrast (like if yo master several tracks from a drum kit against another instrument, you may want all your drums tracks to have same colors).

That depends on the FFT settings. You used a window size of 1024 (set by default).

Indeed, my GFX analyser and Span FFT didn't match but that didn't change the FR :P

Having slope may not be "accurate" but allow to have something that matches more "how we feel the sound".
In this Linkin Park song, I find bass is nicely balanced with medium and heigh. Span slope at 4.5 shows a curve globally flat. If I set it to 0, then I get the same results as the GFX analyser: a bump in bass display.



Here is with Sines at various octave from a 440hz (I just see you made a track template, I can remake the gif is needed):

In this case, it does make sense to have slope at 0, but in mixing context, I think slope at 4.5 (or custom) is more useful.

From Span manual:

Note that by default SPAN uses 4.5 dB per octave
slope for the spectrum display
which makes it look considerably “elevated” towards the higher frequencies in
comparison to most other spectrum analyzers available on the market.
This setting
can be changed in the “Spectrum Mode Editor” window

Note than SPAN is free and cross platform is you want to test Great plugin, really smooth display! But I'm really curious what a JSFX version can do At least being able to have 16 channel (or even more by modding) is really interesting :P

Thanks again for your consideration

[heda]

this is pink noise generator jsfx routed to it. the average should look horizontal line. This would be very useful.

[FnA]

Nice!

Slope sounds good. Other things span has that I have found useful are zoom feature and +- cents by the note number.

But doing great regardless.

Yep. I sometimes use pink noise to adapt equalization to a room/Loudspeaker by sending the microphone signal to SPAN and set the slope so that pink noise is an horizontal line.

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.

[skippertag]

Many thanks Veto!!

[heda]

Thank you Veto.
It's perfect
and wonderful

[X-Raym]

Oh yes, Reapack release, awesome ! Thanks !

Here is a screenshot of v0.2



I can see indeed it missed the vertical scale and also that there is now up to 40hz bandwith (not sure if that is necessary in most cases ?).

The script to set color from tracks, but maybe a button to reset colors right on the window can be nice too.

Compared to SPAN, the X-axis scale seems to be different:

The 20-70hz scale seems a bit compressed in the JSFX. How come ?

Very good work anyway :P Having such plugin as JSFX allows to bring a lot of customization possibility !

You're right Michael, I really should look into Reapack.

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)

-Michael

[Winfield]

This is great, thanks!

Excuse my ignorance, but how do I set it up as shown above - with inputs from other tracks?

Thanks

[RCJacH]

Hey this is a great one!
As a feature request, is it possible to implement RMS (or some sort of averaging) and peak hold?

[RCJacH]

Originally Posted by Veto

Just out of interest, what would RMS make different for you compared to that?

Freeze/hold is on the list (Skippertag would like to have it too I think) only need to find a little time.

Oh, I'm sorry, I didn't see that integration time setting. That is indeed what I meant.

and when you somehow find even a little more time it would be soooooooo cool to save and load reference curves (although I know this is gonna be a problem because of the different timing options..)

Anyhow...thanks again and a very merry christmas time to you and y'all

[G-Sun]

Very impressive!

[Robert Randolph]

I do not see Veto_gfxanalyzer in Reapack with the repository added. I only see Set colors of focused Veto_gfxanalyzer to tracks sending on channels 1-16

Should that be the case?

[Robert Randolph]

I just added a section for this awesome script on my Reaper Scripts Showcase page

http://admiralbumblebee.com/ReaperSc...lyzer---thread

Thanks!

Anyways I just posted a question in the ReaPack thread.
It might also be of interest which OS version you do have.

Thanks for the feedback btw Robert!

EDIT:
Strange issue, fwiw it works on cfillion's mac.

I don't see it in Windows either. I made sure I have the latest reapack.

Is there anything specific I should be looking for here? I am searching by package, sorting by author... nothing.

edit: AH! It's "Multi Channel Spectrum Analyzer" under "Cockos/Vento".

That totally evaded my searches. Everything is ok!

[skippertag]

I just recognize something that may not be intended...

currently the floating gfx window is just behind my browser screen where I'm typing now..

what happens is, that the cursor (who is of course active in the firefox browser) is also active on the floating gfx window in reaper although it is not active as I'm typing in Firefox. That is of course only happening when the cursor comes into the range of the opened floating window.

Doesn't that waste resources and I'm afraid that I might change things that I'm not willing to change actually while typing in firefox ..

Would you mind checking that Veto? :-)

The loss should be negligible. On my (quite underpowered) system it's not even measurable (below 0.01%).


That won't happen. If not focused or covered by another window the JS only tracks mouse cursor x- and y-position, never mouse clicks, drags or keyboard events


Possible workarounds I could do (but would rather not to):

• disable graphic processing when transport is stopped/paused:
  impractical because there are situations where one would use it on stop/pause too (i.e. input monitoring)
• disable graphic processing if any of the active inputs are below a threshold x after some time t:
  I'd like to avoid that because if t is too small it would cause flicker with standard usage and if it's too big it would confuse users ("why the readout was visible a second ago and now it is not?")

If this still bothers you (I honestly can't see why though) you'd need to switch to edit mode in the analyzer (click the surface) before you switch to other windows.

Hey thank you for your fast response...it's not bothering at all... it just flipped to my eyes today and I thought "man, that's not the case with other windows applications :-)

[skippertag]

You're most welcome, but I (We) are the ones to thank YOU! :-)

[mrelwood]

Oh man, magnificent work, Veto!

Regarding the Slope: I noticed that while higher pitched tones from the tone generator are now shown as louder in gfxanalyzer, Voxengo SPAN shows them as flat.
So pink noise is flat on both, tones flat in SPAN but sloped in gfxanalyzer!

I couldn't wrap my head around this until now: I had a 1/6th octave smoothing enabled in SPAN.

I modified the original gfxanalyzer to reduce graph opacity at high frequencies (FFT size dependent ;o) to see more precisely what's going on within the
big yellow blob instead of being blinded by it... But smoothing at the analysator level would solve these both issues!



I recently dipped my toes into modifying JS plugins without previous coding experience beyond Excel, so I don't have the slightest idea how one would go about this.
I think Smoothing would be a marvellous addition to the Veto Analyzer!

[Ozman]

Looks like the Reapack Repo is gone now.

Ah, hm, I just noticed this thread. I worked on something pretty similar for my needs not so long ago. I've uploaded it in case anyone is interested:
Repo: https://github.com/JoepVanlier/JSFX
Reapack: https://raw.githubusercontent.com/Jo...ster/index.xml

There's also a lua script that automatically links all your top level tracks to the analyzer. I mostly use it for the last steps when I'm putting a track together.

I see the buttons for the "channels" can "solo" the view of a particular channel. That's a nice touch, and so is the smoothing.

I was initially confused by the "16 channels" of the plugin thinking it meant channels 1+2 (3+4 etc.) of the plugin were representing stereo audio input pairs. I realized later each "channel" 1-16 of the plugin must be a L/R sum of audio input channels. (So you can feed it 16 stereo pairs of audio inputs.)

Oh also I realized if I right-click on the channel number it makes it "bold" but it doesn't seem to affect whether the channel is displayed or soloed. Is there a function that happens when right-clicking the channel number?
