I found that Ableton may have an issue supporting offline oversampling settings in plugins. I tried with Voxengo Tube Amp and your Chow Tape Model, both which allow to set an oversampling rate that is supposed to be applied in the exporting stage.chowdsp wrote: ↑Wed Sep 08, 2021 3:19 pmThanks! I had some users requesting a linear phase option, and since I was overhauling the oversampling menu anyway, it seemed like a good time to add it. I use the oversampling implementation from the JUCE framework which has easy-to-use options for choosing between a lower-latency polyphase IIR anti-aliasing filter or an linear phase FIR filter.heavymetalmixer wrote: ↑Wed Sep 08, 2021 3:12 pmYou're welcome, your plugins are awesome and more people should know about them.
Also, what was the idea behind the Linear Phase oversampling?
I did run a test signal (a sine signal at around 8 khz) through the effect that would deliberately cause aliasing at 44.1 khz project sampling rate, but where aliasing should pretty much be reduced to irrelevant amounts once the offline oversampling setting has been applied properly. I double checked by manually setting the realtime oversampling rate up to 8x and 16x and the aliasing wouldbe drastically reduced. However, exporting with only offline OS set to these higher rates would output a signal with heavy aliasing, equivalent to no OS applied.
This seems to be caused by Ableton not reporting the status to the plugin, at least that's what Voxengo's developer Aleksey explained.
