If you set up and use the oversampling correctly, you should not hear a low cut. Just load your plugin into Plugindoctor with oversampling only. Here is what I got:

- I haven’t used `addOversamplingStage` before. If you want different oversampling rates, try this:

```c++
        for (size_t i = 0; i < numSamplers; ++i) {
            overSamplers[i] = std::make_unique<juce::dsp::Oversampling<FloatType >>(
                    spec.numChannels, i,
                    juce::dsp::Oversampling<FloatType>::filterHalfBandFIREquiripple, true,
                    true);
            overSamplers[i]->initProcessing(spec.maximumBlockSize);

```

- I would suggest using `useIntegerLatency=true` to make your life easier (`setLatencySamples` only accepts integers!). And don’t forget to report the latency after changing oversampling rates.
- You should also pay attention to the `processSamplesUp` and `processSamplesDown`. See the discussion here
