    Hi,

    Just want to ask about the latest DDMF Superplugin latency that I found a little strange when real-time oversampling is activated inside the plugin. The higher the oversampling, the lower the latency gets which I believe is kinda the opposite to what we all used to. If this is normal why would all other plugins do it the other way around ? Just wondering if this is a bug, I've roughly tested it but no phasing issue occurred in case the plugin mistakenly reporting the latency to the host. Maybe someone could explain why it behaves that way.

    WIN11, Cubase.

    Thanks.

    EDIT : Added screenshots

    Here's an example of Superplugin with Waves API EQ and 2500 in it.

    1) No OS

    2) 2x OS

    3) 16x OS

    This is normal with fixed sample size latency. Because the higher the samplerate and the more samples per second, the shorter the same sample size would be in time.
    Latency isn't introduced by upsampling/downsampling anyways, but by antialiasing filters and whatever else devs implement in the process.

    This is what I meant :
    1. The plugin introduces no latency at no oversampling

    2) at 2x oversampling, the latency added is 1.0ms

    3) and at 8x oversampling the latency increases to 3.1ms

    This is what I believe every other plugin doing.

    Why do they make such high latency plugins? if it effects the playback
    i remember bouncing wavs, when using high latency fx! then resync them after
    i have some old vst DLL files with no latency & run great!

    It differs from plugin to plugin. Some increase by like 1 sample. Some increase twofold. Some decrease.
    The other decreasing one I can think of is FabFilter Pro-L.
    As I said, latency isn't caused by upsampling/downsampling itself, but by what else is implemented. And, strictly speaking, is being set by the devs following reasoning they only know. Maybe they just want to be safe knowing audio is the same between different samplerates in realtime. Maybe they use different filters for different oversampling rates. Maybe some other antialiasing or optimization is going on.
