Vocal Compressor is a simple compressor plugin optimized for speech and singing voice.
It is heavily inspired by how mastering limiters work and features the same kind of lookahead (about 1ms) and program dependency but in a soft knee compression context.
Additionally, the "HF Sens" sidechain filter allows you to fine-tune the sensitivity to high frequencies. It is similar to what you can find on the back of a famous optical compressor.
