About the Stereo Enhancer block
The Stereo Enhancer increases stereo imaging. It's NOT a double-tracking tool.
More information about stereo enhancement and double-tracking is available in:
- The forum's
Live double tracking
thread. - Wikipedia's
Out of Phase Stereo
article. - Sound On Sound's
Classic Stereo-widening
page.
Input and output: mono or stereo
While a stereo INPUT signal works best with the Enhancer, the Enhancer can also stereoize
a mono input signal.
Regarding the OUTPUT: Using the Enhancer makes sense only when the output is stereo. Also, don't use it if you only use one channel, either left or right, of a stereo output signal.
Read Mono and stereo signal for more information.
Enhancer types
- Modern
- Uses multi-band techniques for a natural effect. It widens stereo signals and “stereoizes” mono signals. Low Cut and High Cut parameters allow control over the region of influence. The effect is mono-compatible: there are no phasing problems when summing to mono.
- Classic
- Uses old Haas effect delay-based processing. One channel is delayed by a very small amount to increase the apparent stereo separation between the left and right channels. Try a setting of 35% = 7ms (100% = 20 ms).
- Stereoizer
- While the Classic and Modern types rely on micro-delays and inversions to create artificial stereo, the Stereoizer type uses multiple high-order filters to create a realistic stereo image. The effect is mono-compatible: there are no phasing problems when summing to mono. Don't use this type if just using one side (left or right) of a stereo output, because phasing effects may be encountered.
FRACTAL AUDIO QUOTES
The algorithm is such that when Width is zero there is significant cancellation in the right channel that will cause a shift in the balance.
[1] Classic enhancer mode is just a delay on one side (adjustable from 0 to 20 ms) plus pan & phase adjustment. The non-delayed side will tend to seem louder, just like if you used a delay block to get the same delay time.
[2] An allpass filter is a crude approach and will create comb filtering when collapsing to mono. The Stereoizer is expressly designed to prevent this.
The stereoizer rocks! Try this approach:
- Set Width to 100%.
- Set Depth to 0%.
- Gradually increase Depth.
- When you find a setting you think you like, set width to taste.
See the forum's Understanding the Enhancer block
discussion for more information.
Enhancer block position on the grid
- Place the Enhancer block at the end of the chain, before the Output section.
- Place the Enhancer block after all mono blocks, before stereo effects.
- Place the Enhancer block after mono blocks, and split its output into two mono blocks that each process a side of the stereo image (left or right), like Drive or Amp blocks.
Tips, tricks and troublehooting
Factory presets
The Stereo Enhancer block is present in some factory presets. Search the Factory presets wiki page for enhancer
.
Create a global Enhancer effect
To create a global Enhancer, add the Enhancer block to selected presets and assign Bypass to an External controller. Now use the Initial Value parameter for that external controller in the MIDI/Remote menu to engage or bypass the block in all those presets.
Avoid phase cancellation
When summing a stereo signal to mono, the Enhancer in Classic mode can cause phase cancellation. Use the Modern or Stereoizer mode instead which are mono-compatible to prevent this.
FRACTAL AUDIO QUOTES
[3] Never put the enhancer in parallel or you'll get phasing problems. That's why there is no bypass mode because it should always be in series.
[4] The Modern Enhancer will survive collapsing to mono but any enhancer should be used judiciously, especially for recordings.
Read Mono and stereo signal
for more information.
Widening the Panner
Make the Panner effect in the Tremolo/Panner block appear fuller and wider by adding the Enhancer.
Alternative: Delay block
FRACTAL AUDIO QUOTES
[5] Another way would be to use the Delay block. Set the Mix to 100%, dial in the desired amount of delay and set Balance to full right.
Alternative: Pitch block
Use the Pitch block with modifiers, as demonstrated in the Petrucci Rig factory preset.
