# Diopser You were expecting Disperser[ยน](#disperser), but it was me, Diopser! Diopser lets you rotate the phase of a signal around a specific frequency without affecting its spectral content. This effect can be used to emphasize transients and other parts of a sound that in a way that isn't possible with regular equalizers or dynamics processors, especially when applied to low pitched or wide band sounds. More extreme settings will make everything sound like a cartoon laser beam, or a psytrance kickdrum. Because this plugin lets you crank every parameter up to 11, you may want to avoid rapidly sweeping the frequency parameter down all the way to 5 Hertz when you have many filter stages enabled. Because of the way these filters work, this may cause comparatively loud resonances in the 0-15 Hertz range. In that case you may want to use a peak limiter after this plugin until you understand how it reacts to different changes, or maybe you'll want to check out [Safety Limiter](../safety_limiter), which is made for this exact purpose. This is a port of https://github.com/robbert-vdh/diopser with more features and much better performance. ![Screenshot](https://i.imgur.com/QLtHtQL.png) *Disperser is a trademark of Kilohearts AB.

Or if you're not signed in on GitHub, then you can also find the latest nightly build [here](https://nightly.link/robbert-vdh/nih-plug/workflows/build/master). On macOS you may need to [disable Gatekeeper](https://disable-gatekeeper.github.io/) as Apple has recently made it more difficult to run unsigned code on macOS. ### Building After installing [Rust](https://rustup.rs/) with the nightly toolchain (because of the use of SIMD), you can compile Diopser as follows: ```shell cargo +nightly xtask bundle diopser --release ```
