  • These filters are awesome .They come in handy once in a while !!

    Used it today , for very cool vibe!

  • I agree with Tim. These have been quite useful to me, particularly for percussion. Shakers, tambourines, etc., can be nicely ‘tuned’ to avoid conflicts. You can get that old ‘Motown’ kick sound with ’em too. These filters are very unusual, but nothing else I’ve used can do what they do, when needed.

  • Agree with Rex, very unusual and unique tool that won’t necessarily work on every sound but is absolutely perfect in some situations! Another top-notch release.

  • I got that filters recently and I find them raising level near the freq marked, apart from the cut they do.
    Cutting in 10 k causes a raising level over 8 or 9k, is a normal behaviour?
    Please, could you give me info about the best use of the filters?

    • Yes this is normal. Filters have what is known as a “resonant peak” near the cutoff frequency. These are best used for any musical HP/LP tasks.
      I recommend playing with a filter plugin with resonance/Q control to get your head around the functionality.

  • Thank you, Eric.
    I’ll try them in the next project.

  • King Tubby Filter , use like a phaser !
    Dubwise mixing
    Very cool stuff

  • never heard an analog filter in a computer, untill now, just slams all over other vst filters
    sounds analog, no mistake about it, great on drums and synths

  • Hello , can you tell me how input impedance ( source ) and impedance destination you use for the sampling please ? I know this filter is reactive to both impedance and change this unique cutoff in different way …so if you can tell me ?

  • How to contact you ?

  • Hi Eric, thanks for this sampling. I bought it some years ago but I never checked the transfer function. I have found some strange curves on Vintage Langevin LF filter, surprisingly in some cut frequencies it is working as a broad notch filter. I could upload some screenshots but you can checked with easily with Voxengo SPAN and a pink noise generator.

    Here the strangest one, for the second cut frequency:

    Can you confirm if that is normal in Langevin filter? I expected for a passive 4th-order LPF?
