About ring modulation
A ring modulator produces the sum and difference of frequencies in multiple waveforms. This often results in 'robotic' sounds.
See Wikipedia's Ring modulation
article for more information.
FRACTAL AUDIO QUOTES
[1] I absolutely hate ring modulators so I was determined to make one that could actually be used in a musical context rather than making robot noises.
Ring Modulator types
The Ring Modulator block has three types:
- Classic
- SSB Upper
- SSB Lower
SSB Upper
and SSB Lower
select the upper and lower sidebands of the modulation.

Pitch tracking
When this is enabled, the frequency of the oscillator tracks the pitch of the notes on the fretboard. This works specially great with lower octaves, see below.
Tips, tricks and troubleshooting
Factory presets
The Ring Modulator block is present in a few factory presets. Search the Factory presets page for ring
.
Octaver effect
The Ring Modulator works great as an Octaver by adding a low octave:
- Enable Pitch Tracking
- Set FREQ MULTIPLIER to 0.500
- Turn down HIGH CUT FREQUENCY
For even more funky business add a Phaser or an Auto-Wah effect.
Add a fuzz after the Ring Modulator to create a filthy and fuzzy
low octave.
FRACTAL AUDIO QUOTES
[2] I've improved the Octave Divider quite dramatically. In my research, however, I discovered a better way to achieve this effect, IMO. Use the Ring Modulator. Set Track to On and FMULT to 0.5. Adjust Locut and Mix to taste. The only drawback is that it's only one octave but it tracks way better than any analog technique.
Tremolo effect
See Ring Modulator as a tremolo
for more information.
Phaser / Uni-vibe effect
You can also use the Ring Modulator as a phaser or uni-vibe
.
Pedal control
Attach a pedal to the FREQ parameter to create a special effect.
Multitap Delay
The Multitap Delay block can apply ring modulation to delay trails.
