Hey everyone! I’ve been getting some questions about why the phase looks so unusual when measuring the Shape2 Advanced plugin in Plugin Doctor. To help explain what’s going on, I’m sharing a tool that I use in the video. It’s a special filter plugin I built for myself over a year ago—a unique linear-phase filter called SPLITT (it’s actually the same filter used in Shape2 Advanced).

And here’s the best part: I’m giving it away as a freebie for you all! 🎉 Even though it’s quite specialized, I hope some of you will find it useful. It’s not your everyday filter, but if you’re into sound design and need some creative control over your frequency bands, this might come in handy.

What SPLITT Does

SPLITT is a linear-phase filter designed for splitting a signal into two bands—upper and lower—so you can process each separately. It’s also great for combining two different masters in a weird and fun way: use the low-band from one and the upper band from another, for example. As you probably understand by now, this is not meant for typical filtering tasks, but it offers a lot of flexibility for unique use cases!

Quick Start Guide

Here’s a rundown of the controls to get you started:

• Crossover: Set the frequency where the split will happen. Lower frequencies can be tricky to set with the knob, but you can type the exact value by clicking on the number below the knob.

• Taps: This adjusts the steepness of the filter. Higher values make the filter steeper, but they can also be taxing on your CPU. For most tasks, staying between 200-900 should work well, though you might need higher values (up to around 8000) if you’re working with very low frequencies (0–60 Hz). Pro tip: The maximum value (20000) is extremely CPU-intensive—use with caution!

• Matrix Controls: These options let you route the low and high bands individually:

  • In LP (Low-Passed): Choose whether the low-band audio comes from the main stereo input (1-2) or the sidechain (3-4 input).

  • In HP (High-Passed): Choose whether the high-band audio comes from the main stereo input (1-2) or the sidechain (3-4 input).

  • LP Out: Set whether the low-band output goes to the main stereo output (1-2) or the 3-4 output channels.

  • HP Out: Set whether the high-band output goes to the main stereo output (1-2) or the 3-4 output channels.

I decided to only create a VST3 for now. I’m still figuring out signing and notarizing for Mac and won’t build any AU until I got that working.

The final update for today is for Nick’s Search and Bus script.

Updates v4.03:

• Added a loop that checks if a track (or tracks) are selected

• Added an error message if no track or all tracks are selected

• The selected track/tracks are not shown in the search results

• Made a blinking cursor to make it clear that it’s a search box

We all want Nick to use Reaper for mixing, don’t we? To make him do that he needs the script ‘Search and Bus’ that I just made (instead of watching Netflix during lunch).

This script is handy in large projects where you have 100+ tracks and want to create a send to one of your trillion FX buses.

Here’s how you use it:

• Select the track where you need to add a send.

• Run the script, preferably with a key shortcut that you created. You will now see a list of all available tracks.

• If you type a part of the receiving track’s name, such as ‘Reverb,’ the list will be updated to show only tracks with ‘Reverb’ in their name.

• Click the track that you want to create a ‘send’ to from the list.

• Done!

How to Use

• Download the attached Script 

• Load it into Reaper: Actions > Show Action List > ReaScript > Load.

• Add a short command to the script (optional)

• Run the Script: Start it to display the timers and new controls.

I added all the stuff I said I wanted to add in the initial video plus some extras, here’s BassGlove v1.50!

Changelog:

• Added a second experimental filter that ‘blurs’ the signal, it creates a deeper tone with more audible harmonics

• Added a control to fine-adjust the threshold

• Added a ‘Curve’ control. The ‘curve’ knob will change the envelope follower from linear to exponential

• Made a demo (attached below)

• Finished the manual

BassGlove applies an experimental filter at the transients / highest peaks of the signal. The result is a very natural punch in tracks that are a little thin. It’s made for mastering but as with any tool, you use it how and wherever you want! =)

Enjoy!

TALC has been updated to version 1.10 – TALC got mid/side!

Changelog:

• Added a mid (sum) / side (difference) slider

Talc will help you boost your high-end without making things sounding harsh or unpleasant. It does that by blending in a linear phase high-shelf boost dynamically. Two different dynamic engines control the amount of boost, they’re called “Dynamic Dry-Wet” and “Sibilance Protection”. The “Dynamic Dry-Wet” follows the overall envelope with a 10 ms attack and a 2-second release. It will make sure that your high-end follows the energy of your music. The other one, Sibilance Protection, protects the signal from boosts that may end up sounding harsh. It will bypass the effect as soon it detects sibilance or a sharp transient. The result is a smooth high-end boost hard to achieve using other tools.

Tip!

Even though TALC was made with mastering in mind; Try it as your high-end booster on vocals. I bet you won’t need a de-esser.
