AudioThing has introduced a new audio plugin developed in collaboration with Hainbach. A passive bandpass filter, Octaves is modeled on the portable Brüel & Kjaer 1613.
Octaves is our latest collaboration with Berlin-based composer and YouTuber Hainbach. It is a filter plugin designed to take apart the audio spectrum in spreads of octaves, allowing for unique and enchanting spectral sound design effects. Octaves gives you a retro-scientific approach to sound that echoes the timeless productions created in the BBC Radiophonic workshop or the WDR Studio für Elektronische Musik by the Avantgarde masters, and modern places like Willem Twee, Strøm, and Hainbach’s own laboratory.
Octaves features
- Passive Bandpass Filter.
- 10 + 1 Bands.
- Oversampling up to 16x.
- Impedance and Artefacts controls.
- Resizable Window.
- Preset system with randomizer.
- Brightness and Contrast Controls.
Octaves for Windows, macOS, and Linux (VST/VST3, AU, AAX, CLAP) is on sale for the intro price of $19 USD / 19 EUR at the AudioThing store and from Plugin Boutique until April 30th, 2026 (regular 39 USD/EUR).
