It's not a finished work, just a show off of what I've been working on in the last two weeks. It is meant to be a part of a more complex device.

The range is 6Hz to 96kHz. I always wanted to see what's beyond the audible range.

The resolution is 2x that of Reason's SA. First I tried to make it evenly dense on the logarithmic frequency scale, and it even worked, but the latency at the low frequencies was too high (3 seconds). I had to make it the usual way. There is still a use for that evenly dense approach, in a spectrogram device, for example, where the latency does not matter.

Looks good and the gfx are quite fast

hello,

i'm an instabuy when you release this RE

at around 2 minutes: i love the ocean wave sounds

would be great for a ringtone on the phone

it is neat to see what you can't hear

cheers and eat well,

j

any idea of a release date?

will it work with R10 / windows 7?

1) Too many ideas, I'm not telling so as not to get you confused. I'm already confused myself.
2) Definitely.

i have often wanted to see a spectrum analyser go higher than 20k. this def has my interest

would not mind to have this as a dedicated Analyzer RE.

Do not forget to have multiple inputs...Sadly you cannot automatically do this in RE as you can in a VST via static data...

Yes, multiple inputs/thrus with curve differences being shown in two colours for +- differences, like ADPTR Sculpt does.

You mean, multiple live spectrum graphs on the same plot? Is it really of any value?

I thought of a spectrogram device, where you could record and store multiple spectrograms and then compare them, placing them over each other. But it's next in line, now I'm busy with another thing. As for multiple inputs, an external input switch would do.

Yes I´m talking about two curves simultaneously playing and being displayed with colouring for differences between the two like here in Sculpt. Blue stands for negative and brown for positive changes:

Where do those two signals come from that they are so similar? Please don't get me wrong, I'm not trying to argue, I just want to evaluate how often there is a need to use the feature.

1. For newbies. It seems to me that it would be a good idea to color the scale to indicate the frequency spectrum of the instruments.

2. For mastering. Store in memory a preset - pink noise (popular opinion is to reduce by pink noise), or other presets for different genres.

Sculpt is sort of a bus dynamics device, saying it´s the displayed combination before and after the shaping. And that´s exactly what I would like to do universally. Like feeding one input with an audiosignal before and the second input with the signal after an arbitrary effect, though especially suited for EQing and Dynamics. And thus being able to see how a whatsoever device alters the frequencies across the spectrum, not necessarily to compare two different bassdrums or synths e.g., though it could be interesting aswell.

Simply for visual impression deliverance (had to lower the quality for the GIF to stay within the maximum upload filesize, hence the lossy display of the greyish area beneath the curves):

Oh and I really like the gridline design in Sculpt. At the size of the original screenshot they are merely 2 pixels wide and differ through transparency aswell,
Delivering a quite clean view. Less fighting over visual foreground for the curves :-)
