Dattorro Plate Reverb
A classic plate reverb implementation based on Jon Dattorro’s renowned algorithm from the 1997 paper “Effect Design, Part 1: Reverberator and Other Filters.” This algorithm is celebrated for its lush, smooth sound quality and has become a reference standard in digital reverb design. Perfect for adding rich, shimmering ambience to your music.
Routing note: Dattorro Plate Reverb is a stereo plate model. When routed with more than two channels, all routed input channels feed one shared mono-to-stereo plate, but the wet/dry mix is written only to the first routed stereo pair. Additional channels contribute to the plate input and otherwise pass through unchanged, including when Dry Mix is 0%; they do not receive a wet return and are not independent plate tanks.
Listening Experience Guide
- Lush Plate Sound:
- Classic plate reverb character
- Smooth, dense reverb tail without metallic artifacts
- Beautiful shimmer and warmth characteristic of plate reverbs
- Versatile Ambience:
- From subtle room enhancement to expansive halls
- Works beautifully with any music genre
- Adds smooth polish and space to music
- Natural Movement:
- Modulation adds organic life to the reverb
- Prevents static, artificial-sounding tails
- Creates a breathing, living space around your music
Parameters
- Pre Delay - Initial silence before reverb begins (0.0 to 100.0 ms control; use values below 100.0 ms for effective pre-delay)
- 0-10ms: Immediate reverb, intimate feeling
- 10-30ms: Natural sense of space
- 30-99.9ms: Creates impression of larger spaces
- Avoid exactly 100.0ms when you want maximum pre-delay; the current implementation treats that endpoint like no effective pre-delay
- Bandwidth - Input signal filtering (0.0 to 1.0)
- Lower values: Darker, warmer input tone
- Higher values (near 1.0): Brighter, full-frequency input
- Default 0.9995: Optimal as suggested by Dattorro
- Input Diff 1 - First stage input diffusion (0.0 to 1.0)
- Controls initial smearing of input signal
- Default 0.75: Recommended value from Dattorro paper
- Higher values: More diffuse, smoother early reflections
- Input Diff 2 - Second stage input diffusion (0.0 to 1.0)
- Further spreads the input signal
- Default 0.625: Recommended value from Dattorro paper
- Works with Input Diff 1 to create complex diffusion
- Decay - How long the reverb tail lasts (0.0 to 1.0)
- Low (0.1-0.3): Short, controlled decay
- Medium (0.4-0.6): Natural room-like decay
- High (0.7-1.0): Long, expansive tails
- Decay Diff 1 - Decay diffusion in the tank (0.0 to 1.0)
- Controls density during decay phase
- Default 0.70: Recommended value from Dattorro paper
- Affects the smoothness of the reverb tail
- Damping - High frequency absorption over time (0.0 to 1.0)
- 0.0: No damping, bright reverb throughout
- 0.0005 (default): Very subtle, natural damping
- Higher values: Darker, warmer decay
- Mod Depth - Amount of delay modulation (0.0 to 16.0 samples)
- 0.0: No modulation, static reverb
- 1.0-4.0: Subtle movement, adds life
- 8.0-16.0: More noticeable chorus-like effect
- Mod Rate - Speed of modulation (0.0 to 10.0 Hz)
- 0.5-1.5Hz: Slow, gentle movement
- 2.0-4.0Hz: More active modulation
- Higher values: Fast, shimmering effect
- Wet Mix - Amount of reverb added (0 to 100%)
- 10-30%: Subtle enhancement
- 30-50%: Noticeable presence
- 50-100%: Dominant reverb effect
- Dry Mix - Amount of original signal (0 to 100%)
- Usually kept at 100% for normal listening
- Reduce for special effects or ambient washes

Quick Start Guide
- Set the Basic Character
- Start with Decay to control reverb length
- Adjust Pre Delay for perceived distance
- Set Wet Mix for desired reverb presence
- Shape the Tone
- Use Bandwidth to control input brightness
- Adjust Damping for high frequency decay
- Fine-tune diffusion parameters for density
- Add Movement
- Set Mod Depth for subtle variation (try 1.0)
- Adjust Mod Rate for speed (try 1.0Hz)
- These parameters add life to the reverb
- Final Balance
- Adjust Wet/Dry mix to taste
- Trust your ears for the final settings
- The default values are a great starting point
