No worries at all – and sorry, I assumed you were using Logic based on the thread topic.

In FL Studio, the simplest approach is to insert Scaler Audio 3 (Audio FX) directly onto an audio track.

If you’d prefer to detect audio using the Instrument Plugin version of Scaler 3, there may be a way to route audio via sidechaining — similar to how it’s done in Ableton Live — however I’m not an FL user myself, so I can’t say for sure.

If you haven’t watched them already, I’d recommend checking out the [Audio Detection Introduction](https://youtu.be/V9yfiu_OA-8?si=KOoS6y2QcrL9IIsN) and [Plugin Types Overview](https://youtu.be/aMP0lle2yS0?si=6QaOeYK0Ds470mfS) videos. Cheers!
