And the EQ is out to the public :)

Congrats!

I'll give it a try. Thanks.

Great 🙂

I would also be glad for some serious feedback.

So you finally uleashed it on KVR. 🙂

Don't forget to look at more options to get your plug-in exposed.

Cheers!

Hey Mo!!!!

I almost forgot to credit you for the asm help. But I ended up not using any of them any way. But still TNX! You are now also mentioned on my web site.

Regards

Ah no problem. I haven't had time to test yet, but will soon.

Thank you.

Ok,

The GUI and big display is nice but also uses a lot of CPU. When closing the GUI, i notice the CPU use drops. Optimizing the GUI and maybe make it smaller will make it more usable on more computers and laptops. As it is now you'll need a heavy gamer rig to run stable with more instances and other plugins. The CPU use when closed is also too much, so optimizing is needed for your stream processing also IMO. Here 12-15% CPU and other EQ's is max 2%. On the sound side i'll say OK for low and mid, but for high frequencies it is not amazing. Running 44100 Hz and compared to analogue EQ's you'll here the difference, as yours sounds more digital/undefined in the high frequencies. It's better in 96000 Hz but thats normal as the algorithm problems is pushed to 20-48 kHz where its not as audible. Typical the coefficients can become "weird" when boosting or lowering near Nyquist frequencies (up between 10-22 kHz in 44100 Hz). Time travel seems to do nothing.? -Great idea BTW. I like the GUI but the fact you can get better sound for 1/10 CPU use with existing 64-bit intern (but some is expensive) plugins, makes it not a keeper here so far. That said, keep on doing. Looks good.

Thanks Mo for your nice review. I have to comment what you state. Here we go:

-The GUI... yes I think this needs optimization. I get the same CPU rise in task manager aswell. Did not think of check that before 🙂 -Optimizing the streams is harder because double precision is not yet possible in asm or code. In my pc (three years old Core 2 Duo at 2.4) it use prox 3-4% cpu @ 44.1and 14% @ 192kHz SR in Reaper. But I will have to keep looking for optimizations. -About the sound... I am planning to implement allpass filering to compensate for phase issues and I guess the only other way to do it better is to do oversampling at 44.1 and 48kHz. But it costs even more CPU and in not possible alongside double precision in SM yet. 🙁 The benefit of double precision is rated as better than oversampling regarding quality. 😉 -Time travel does several things. It adds some noise. Changes the frequency response. Adds harmonics. All in a dicreete way. Maybe I'll have to make it more evident. But it is not ment to destroy the sound. There was some good stuff back in the 50's aswell. Try stting up two tracks in your DAW and phase invert them. Set the slider at 2010 on one and 1950 on the other. Then you hear the difference 😉

Just have to keep working on this thing 😀
