Ultracomb in Bitwig

Added 2024-06-25 15:18:12 +0000 UTC

In AU5's recent video, he introduces the Ultra Comp, a filter combination in Ableton Live using devices like a flanger, phaser, and frequency shifter. This summary will show how to recreate this in Bitwig Studio. The Ultra Comp creates a spectral filtering sound and a moiré pattern in the spectrum analyzer.

Overview

Device Creation: Starts with a flanger using two delays, then uses phase-inverted flangers for an All-Pass effect, ending with a frequency shifter for a Shepard tone effect.
Bitwig Implementation: Uses Bitwig's All-Pass modules to replace phase-inverted flangers, analyzes with EQ curve analyzer, and creates custom filters.

Key Points

Flanger Creation:
- Uses two delays to split the signal, achieving minimal delay for flanging.
- Combines the delayed signal with the dry signal.
All-Pass Filters:
- Create notches in the frequency spectrum.
- Mixed with the dry signal, they act like low-pass filters.
- Increasing poles adds more notches, creating complex filters.
Frequency Shifter:
- Adds a Shepard tone effect by shifting frequencies.
- Can create stereo effects by shifting left and right channels differently.
Bitwig FX Grid:
- Utilizes 50 All-Pass modules for extensive filtering.
- Adjusts phase relationships with a frequency knob.
- Blends dry, delayed, and dispersal signals for the final output.
CPU Considerations:
- More All-Pass modules increase CPU usage.
- Duplicating the effect amplifies it but also increases CPU load.
Alternative Method:
- Uses Bitwig’s frequency split for spectral filtering, less CPU intensive.
- Can add effects like flangers, phase shifters, or frequency shifters in FX boxes.
Sound Characteristics:
- Different methods produce distinct sounds.
- All-Pass method offers unique audio qualities.
Practical Use:
- Suitable for color-based producers.
- Allows for extensive sound modulation and customization.
