Hello,

if i understood right, you say AutoPre, set -db when there is a +db in Filtersetting and some db ( -2) on top to save for Clipping?
But when there is no +db in Filtersetting, will the AutoPre set -db for save to, or will it be not?
Sorry for that Englisch

I am asking, cause i use a Low Cut Buterworth at 49HZ with 8. In Pipeline on CamillaDsp seems no Overhanging about 0DB, but with AutoPre there is Clipping shown in CamillaDSP.
No big Problem for me, i could handle it manually, but maybe the Info helps.

Hello,
When I try to install the FusionDsp plugin ,it displays an error message:

An error occurred while installing the plugin Plugin failed the dependency check Volumio version 3.211.0 not usable with plugin. The plugin cannot be installed on this version of Volumio.

I have tried all the proposed versions of FusionDsp: 1.0.45, 1.0.47 ,1.0.48.

Thanks

Hello,
Volumio >v3.236 is required to install FusionDsp. Earlier versions are missing mandatory components.

Can you explain why you are using a such old version?

[Bob755]

I installed volumio for the first time à few days. I used the image from the website.

[balbuze]

version from this official site is v3.449. Where did you get yours?

[balbuze]

I moved this thread in this category Plugins to be coherent with other threads.

[Bob755]

I thought I got it from that site but not sure why I got an older version.
Updated to 3.449.
All ok now. Thanks

Hi,
When only negative values are found -2dB is set because even in that case clipping may occur due to phase rotation.
But I need to check in your case with the kind of filter you have.

Edit : I made some test and I can’t get clipping even at 0dB. Auto preamp in V1.0.48 set -0.05dB with your filter though

[Flames]

Hm ok,

could be that some Radiostations has a higher output?
For the test i heard 80s80s DarkWave (sorry ) , and 1.FM Blues.

[balbuze]

Even with it I can’t get it to clip! Do you use an other filter?

Fusion DSP Auto Pre-Amp Setting?

Can anyone explain what this setting is actually doing? I believe it is on by default. When I turned it off, I felt like the loudness went up substantially at all frequencies. It mentions clipping but I am curious to understand what is actually happening. Is this a safety feature to protect your speakers? Thanks [Screenshot 2023-05-30 124350]

hello, There is no problem and nothing to fix… let me explain… A max level in digital domain is 0dB When you set a positive value in the EQ (ex 3dB) for a frequency, it means increase the signal here. As it is not possible to go above 0dB, to get the same relative effect, everything is set 3dB lower exept the frequency you choose. If you don’t do that, signal will be clipped! With a very bad sound. FusionDsp auto adjust this level by default according to EQ settings. You can disable this in …

Thank you for this response, very informative and helpful.

Hello

I discovered that when creating filters using rephase that .txt format is accepted by fusiondsp but there is no change to the sound as evidenced by before and after sweeps with REW. Using 32 bit LPCM .wav format worked correctly. I haven’t tried any of the other options.
Cheers and thank you for your work.

[balbuze]

Hello
Can you please share your txt filter in order I test?
Thanks!

[balbuze]

Hi!
I tested filters made in Rephase, exported as txt and everything works as expected…
Are you sure you use Paragraphic Gain EQ and not Paragraphic phase EQ ?

[TomSy]

When I enable the Fusion Dsp plug-in, the sound goes off. That’s why I want to install this Volsimpleequal

[Wheaten]

peppy (unvalidated plugin) and FusionDSP won’t work together. Either use Peppy or FusionDSP.

[orchardaudio]

Is there a step-by-step guide on how to do DRC with this plugin and REW?

[orchardaudio]

I was able to get a room eq from REW (see below), now how do I load this into Volumio and Camilla? Thanks.
