# Diopser

You were expecting Disperser[¹](#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. If you are experimenting
with those kinds of settings, then you may want to consider temporarily placing
a peak limiter after the plugin in case loud resonances start building up.

This is a port from https://github.com/robbert-vdh/diopser with more features
and much better performance.

### Building

After installing [Rust](https://rustup.rs/) with the nightly toolchain you can
compile Diopser as follows

```shell
cargo +nightly xtask bundle gain --release --bundle-vst3
```

If you don't have access to a nightly compiler (`rustup default nightly && rustup update`),
then you can compile a version without SIMD at a 2x penalty by disabling the
SIMD feature:

```shell
cargo xtask bundle gain --release --bundle-vst3 --no-default-features
```
