Sonnox Pluings Peaking DSP?!

General
1

Hello!

I was wondering why pretty much all my Sonnox plugins seem to peak the DSP when the GUI is open… DSP usage is quite high for a single plugin, but when i open the GUI the DSP Meter starts peaking.

Very significant with Sonnox Inflator and Reverb.

Using TF 1.6.16 with 64 Samples on 48khz.

Thanks!

I use Sonnox Reverb quite a lot, but have never seen this problem.

That sounds like the GUI/meter path may be doing more work than the audio path, rather than the DSP suddenly becoming heavier. As a quick A/B, compare CPU with the editor hidden, then disable the analyser/visualiser if the plug-in exposes that option; also try a larger buffer and watch whether the peak follows the window repaint rate. If the meter is reading host callbacks, checking the same input with a lightweight external meter can separate a display issue from real processing load.

For a controlled check, you can feed a few known tones and octave steps through the same chain and compare the result: frequency and octave test tones.

I tried that, does not change any. Even going from 64 to 256 samples did not help it. when i open the gui for certain plugins, for example bx_digital v3 is also affected, the dsp goes bonkers

Yep, I’ve noticed the same with inflator! Fine to have the plugin running, I just can’t open the teleported view!

Hi all,

If there are specific plugin issues, please always reach out to support as well as here if that’s ok. We can track easier and push towards manufacturers if fixes are needed, but always welcome discussion here.

@cny we have seen this specifically when you have the graph open in bx_digital v3 (TF-4784), if you close that (click button in top right corner), I assume the issue goes away? We are in touch wth Plugin Alliance but haven’t got anything further to add yet.

Sonnox side (TF-3613), we have reached out to them but have yet to get updates or fixes on it. It’s specific to the plugins.

We explicitly show all DSP overloads in the transform.client, a couple spikes here and there are very unlikely to affect audio but we want to be transparent. There could be issues on our side with DSP spikes, but in these instances, we are fairly confident we need the manufacturer to fix it, we’ll keep pushing for fixes.

Thanks,

Elliot
