Hainbach And Audio Thing Octaves Bandpass Filter

Hainbach has released a new plugin with Audio Thing that emulates a Brüel & Kjaer 1613, a 2kg piece of test gear once used for "portable" use  when combined with a a2203/2204 sound level meter for checking noise levels. 
Essentially its a passive bandpass switchable filter with unique characteristics.

Its a piece of hardware Hainbach uses in the studio (one of his worst kept sound design secrets!) and now you can access the sounds i can create it via the new Octaves Plugin.

They've modeled the original hardware with all of its foibles, including poorly serviced switch clicking, and added some additional features.

• Exact emulation of a passive octave filter, originally built with massive metal coils for each frequency band 
•  "Pinging" capabilities: use the "artifacts" control to creatively exploit switching clicks or pair with pulses to create percussion 
•  Hidden "back panel" offers an impedance knob that functions as a resonance control and can turn the unit into a full filter bank
•  Input, output, mix, and soft saturation controls allow you to overdrive the circuit for added color
•  Oversampling options (up to 4x) to manage CPU load and aliasing artifacts
•  Cross-platform support: macOS, Windows, Linux (VST3/AU/CLAP) and iOS/iPadOS (AUv3)

Available now:
VST2, VST3, AU, AAX CLAP
Intro price of €19 from €39
