Re: Dynamic Wave-Table OSC

Awsome - Thanks!

Seems that this is quite near to this what i was thinking about.

Did you already try shorten the distance between 2 wave points and using a wave that ist "shaped" over time?

is it sounding useable?

Kind Regards!

Re: Dynamic Wave-Table OSC

Hello!

Thank you for the massive input - yes it seems that i realy failed explaining at some point

dynamic is not suposed to be "dynamic wave size" - the wave-table size is fixed

Why not just read both wavetables and crossfade then
Yes this is what i asked for.

As i experimented with FFTs ...

Dynamic Wave-Table OSC

Hello!

Just wanted to know if anyone did experiments with a wave-table-osc that is changing the wave-form by time by interpolating between 2 waves?

Thank you!

Re: Module Name

Hi!

There is something (I hope i got you correct)
It is a quite old post so i needed some time to find it:

Example attached in this post.
But: I found no way to get the parent's parent module name ...

Re: Question FFT spectrum rebuild and result interpretation

Thank you!

Got it now and marked many example-schematics as "wrong" (as it just was the nyquist wrong)

Re: GUI's

Good idea - i am missing some gui with advanced properties in FS.
There were a lot in SynthMaker - but since there is ruby they got missing in ruby.

It should also be a little standardized in basic things like preset, midi cc, min max and maybe the gui in ruby.

i'd like the idea and help i i can ...

Question FFT spectrum rebuild and result interpretation

Hello!

I did a research again on some FFT things i did in the past and grabbed some older examples. But i always had an little error at iFFT that gave me a wron signal back (Not that wrong that you just notice it fast)

So i just to ask if someone can confirm this:

If you do a FFT with let's say ...

Re: Ruby Complex FFT CPU speed

Hi!

Thanks.
In the link there is now this code:
https://blog.mro.name/2011/04/simple-ru ... transform/

I just implimented it at it realy runs much faster than the rosetta-code FFT.

The problem is that i realy do not understand asm in any case if i have no debugger that is able to do step by step.

This code fits my needs for the moment.

Ruby Complex FFT CPU speed

Hi!

The last days i made some tests about doing FFTs and iFFTs in ruby.

I've tested those FFT codes in ruby:
m
m
m

All seem pretty to be the same - the fist is a little faster because it creates a storage-map
Both are also reversible - so calculating an iFFT brings up most the original signal ...

Re: HFSoundRestore: restore high frequenzies in your audio f

Hi Thank you for your review!

At the moment i am traveling to several places with good sound-systems and trying to compare.
I did notice some points and i am researching now by splitzting the full track into FFT optimice it and do an iFFT operation. It realy sound more interesting cause the ...
