Sound Forge 17 Pro - Fx Plugin render adds 170ms to end of track

FB33 wrote on 11/22/2023, 10:18 PM

Hello,

I am having an issue when I apply an Fx_plugin_chain to an audio sample.

I am using Fab Filter Pro-Q3 to run a Low Pass Filter on my audio samples and after completing the task, I am noticing that Sound Forge keeps adding 0.170ms to the end of the file for some reason.

Does anyone know of a fix to stop Sound Forge from doing this, as it is a nuisance having to constantly delete this after every FX_Plugin_Chain render. Or is it an issue with Pro-Q3?

I never had this problem using Sound Forge Pro 12, so was wondering if it is a settings fix or something wrong with the program. A friend of mine is having a similar issue, except the extra audio is being added to the beginning of the file as opposed to the end of the file with mine.

@FB33 In case you edit compressed audio files make sure to activate to always proxy compressed audio files in the program preferences.

Hi

In addition to @SP.'s comment, is the low pass filter set with a 'brick wall', ie high rate of cut-off slope, if so this can cause a resonance which may extend the audio by a very small amount.

In this case, try changing the cut-off so that it is 'eased in and out'

If you are saving the audio as an MP3 , the encode process inherently adds a space the head and tail of the file, but usually only a few milliseconds. I have not used FabFilter plugs.

Hi johnebaker, unfortunately this did not work either, tried to low pass at -6db all the way through to brickwall with all settings, and still get the extra 170ms after the render. I am rendering as 48Khz 16Bit WAV files.

Thanks for the help though.

Hi SP,

This didn't work either. I have tried both yours and johnebakers solutions but nothing seems to work. Thanks for the help though!

Just a follow up, I have noticed that this only occurs when using the VST3 instance of the Plugin. I just downloaded and tried the VST2 instance and it worked perfectly. Does anyone know why VST3 and Sound Forge do not like each other?

Thanks for the help in trying to figure out the issue. Greatly appreciated.

I cannot duplicate the behavior with the VST-3 plug-ins I have. Does the behavior exist when using the plug-in singularly as well as in a plug-in chain? It may have something to do with the FabFilter plug-in(s).

Contact Magix support to find out what the deep-thinkers there have to say.
About the only thing I can think of is to disable 'Zero Crossing' Snapping In the 'Options' menu. You could also try resetting SF (Flie menu).

It appears to only be an issue with FabFilter ProQ (VST3). Even running it as a singular plugin it still creates the issue. I have contacted Magix and am waiting for them to get back to me. Thanks for the input!

@FB33

Perhaps it would also be worth contacting the plugin's developers to request their input?
