Chorus Crisp

A Vegas Pro script for creating punchy, layered vocal chop effects commonly used in Sparta Remixes.

What It Does

Chorus Crisp automates a technique where each audio clip is:

1. Split at a tiny offset (20-60ms from the start)
2. Overlapped - the second clip is extended backwards to layer with the first
3. Crossfaded - smooth transition between the overlapping sections
4. Ducked - the second clip's volume is reduced to let the attack punch through

This creates that crispy, doubled vocal effect that's signature to Sparta Remixes.

Before & After

Before

After

Notice how each clip now has an overlapping section with crossfades, and the second portion of each clip shows reduced volume (the percentages like 57.4%, 46.1%, etc.).

Installation

1. Download ChorusCrisp.cs
2. Place it in your Vegas Script Menu folder:

   C:\Users\[YourName]\Documents\Vegas Script Menu\
   

   Or create a subfolder:

   C:\Users\[YourName]\Documents\Vegas Script Menu\ChorusCrisp\ChorusCrisp.cs
   

3. In Vegas Pro, go to Tools → Scripting → Rescan Script Menu Folder

Usage

1. Select the audio clips you want to process on the timeline
2. Go to Tools → Scripting → ChorusCrisp
3. Choose a Preset or adjust the parameters manually:
   • Splice Position: Where to cut each clip (20ms - 60ms)
   • Volume Duck: How much to reduce the second clip's volume (0 to -15 dB)
   • Offset: How much the second clip overlaps with the first (0% - 100%)
   • Crossfade Curve: The easing type for the crossfade
4. Click Apply Crisp

Presets

Preset	Splice Position	Volume Duck	Offset	Crossfade Curve
Jario Style	50%	-3.0 dB	80%	Smooth
Standard	40%	-3.0 dB	90%	Linear
Snappy	35%	-5.0 dB	95%	Fast

Select a preset from the dropdown to instantly apply these settings. If you adjust the sliders manually, the preset will automatically switch to "Custom".

Parameters

Parameter	Range	Description
Splice Position	0% - 100% (20ms - 60ms)	How far into each clip to make the cut. Lower = tighter attack.
Volume Duck	0 dB to -15 dB	How much quieter the second clip should be. More negative = more ducking.
Offset	0% - 100%	How much the second clip overlaps. Higher = more overlap and layering.
Crossfade Curve	Linear, Fast, Slow, Sharp, Smooth	The shape of the crossfade between clips.

Saved Settings

Your settings are automatically saved when you click Apply Crisp and restored the next time you open the script. Settings persist even after closing Vegas Pro.

Settings are stored in:

%AppData%\ChorusCrisp\settings.txt

How It Works

For each selected audio event, the script:

1. Calls Split() at the splice offset to create two events
2. Adjusts the second event's Take.Offset and Start position to extend it backwards
3. Sets FadeIn on the second event and FadeOut on the first event
4. Applies volume reduction via AudioEvent.NormalizeGain on the second clip only

All operations are wrapped in an UndoBlock so you can Ctrl+Z the entire batch.
