Weiss Compressor/Limiter: Transparent Digital Mastering Compressor by Softube

The compressor focuses on transparency. Softube says the Weiss digital compression algorithms are designed to keep dynamics processing clean, including at high loudness levels where limiting can introduce artifacts.

The main controls cover attack and release times, knee settings, ratio and threshold. Low pass and band pass filters let you limit the processing to a specific frequency range. The default faceplate is kept clean, and the more detailed expert controls sit in a hidden side menu.

Because it is a plug-in, you can run as many instances as you need. A common approach is to apply the filtered mode to individual tracks. For example, a low pass filter can restrain only the lowest frequencies of a bass part, similar to a multi-band compressor. On vocals, it can be paired with Softube's Weiss Deess to handle dynamics across the frequency range separately.

The visualisations show where the signal is being compressed heavily and where it is barely processed, which helps with decisions about how much compression is appropriate.
