>> AlexB - Filtek BP1 HP LP Filter : new life for Reverb/Delay and Mastering tricks <<

Post by AlexB » Wed Sep 05, 2018 11:22 pm

Hi,

the vintage BP1 released.

BP1 : Magic Happens!
High Quality Vintage German Broadcast Equipment, the BP1 is a LP and HP filter with either 12dB 18dB or 24db per octave. It is perfect for filtering duties during mixing to cut unwanted frequencies in precisely the low or high ranges. Thanks to the varied filter gradients and overlapping frequency ranges, it is possible to work very surgically in the frequency spectrum. It sounds fantastic on Reverb and Delay giving depth and 3D ambience. It’s a perfect addition in mastering for external sidechaining a compressor to allow the compressor to respond only to a specific frequency range. But real Magic happens when you use it in the M/S technique* by use it flat for the mid - it just cut at 18Hz with natural 6dB slope - and at taste on the side: your mix will sound more finished and tridimensional with more punch and definition.

* the library is not implemented with M/S features, you can use any plugin to do it as the good free MSED by Voxengo.


Two units, previously refurbished, have been sampled in stereo.


. High Quality programs with full dynamics and harmonic content
. Special light edition "le" programs (CPU friendly)
. High Pass Filter 30 40 58 80 112 160 225 320 450 640 900 1300Hz 12/18/24dB oct
. Low Pass Filter 0.7 1 1.4 2 2.8 4 5.4 8 10 14 18 kHz 12/18/24dB oct.
. Generic new AlexB skin for N3 and N4

Please, check the website and download the user manual and try the ABBEY ROAD Classic Preset in the Demo: your REVERB will come back to life, despite what reverb you use: hardware, plugin or Nebula/Acqua ! (Remember to bypass internal eQ/Filter and insert the BP1 preset before the Reverb/Delay)

Oh my. What is this I see? :x Nice to see all the freq settings in one instance!

Here's the demo courtesy of Plugin Doctor. Nice stuff Alexb!

The charts are, in order top to bottom, frequ response, phase, THD, IMD.

Oh and the forum attachement process is messed up. I had to edit the post and and one pic at a time because doing all 4 in one go didnt work.

If you mean one preset with combo HPF/LPF ok but it's not possible in Nebula by too much samples.

Hi Alex. You said the below "cut at 18Hz @ 6dBoct. But the HPF doesn't have 18Hz nor 6dB slope....?? Am I missing something? :geek:

"by use it flat for the mid - it just cut at 18Hz with natural 6dB slope -"

Sorry I can't say more clear... Just insert the preset HPF and leave it flat = slope controls to zero.
The unit has a "natural" HPF at 18Hz 6dB slope due to in/out Haufe transformers.

Ok I understand now. When the HPF is set "flat" its actually not flat, its a 18Hz 6dB/oct filter. :geek:

Yes, it's the trick used at Abbey Road Studios - London.

You are right but what I mean is:
Control is flat, the sampled units was flat. The 18Hz 6dB/oct is NATURAL Roll-Off (HPF) by the transformers and not and internal setup. Every component has NATURAL filter characteristics, even an insignificant electrolytics alone.

So, try to pass a sweep audio into any hardware with flat controls and you'll see some HPF. This is the natural HPF of the gear.

In the early era the tape machine were revered even for their HPF at 16Hz in the line amp.
The same happens with N-eve console as N-eumann, A-PI end so on.

"Technically" only a straight wire of pure silver is almost "flat" as you mean. ;)
