Wire Grind has released Rasp, a free VST3 effect plugin for Windows that adds noise to audio. They say:
Rasp's sound ranges from subtle grittiness to extreme noisy fuzz. Rasp does not clip waveforms, however, the sound is similar to distortion.
Subtle grittiness has a variety of uses, for example, making vocals and drums sound more rough. As for adding higher levels of noise, music makers may wish to do this prior to modulated and automated filtering effects.
Generally speaking, making a track noisier widens its spectrum, and this gives filters more information to respond to. Currently, modulated filtering is popular in various genres of electronic music. Automated filtering is also relatively widespread in electronic music. For example, it is often used to create a "builds up" effect just before a new section of a song begins.
Selected applications:
- Adding grittiness to vocals and drums.
- Preparing a track before modulated and automated filtering.
- Making pad sounds.
Price: Free.
