Edge Silence Cropper

Introduction

This script allows you to trim silence from the edges of items using individual thresholds. It significantly speeds up work with voiceovers, impacts, and other sounds that often have silent tails or heads — especially when dealing with large batches. It can be used alongside Reaper's built-in Dynamic Split for more precise timing adjustments without silence.

Features

• Independent thresholds for the start and end of the item
• Additional margins and fades for item start and end
• Multiple cut detection modes: peak-based and RMS (absolute and relative values)
• Realtime preview mode directly in the Arrange View
• Support for saving and using presets

Installation

1. Install Core modules
2. Open Extensions -> ReaPack -> Browse Packages in the menu bar
3. Find and install ek_Edge silence cropper
4. Execute script ek_Edge silence cropper in the action list
5. Enter licence or start trial for 14 days and restart the script. You can get license key on Gumroad.

Modes

The script provides different crop modes, which should be selected depending on the type of audio material.

Absolute peak (in DB)

The mode searches for the specified peak value starting from the edges of the item and stops when the volume rises above it. This is the most basic mode and is convenient for simple cases where all selected items are normalized equally and have similar dynamics.

Relative peak from max (in %)

The mode first scans items to find the maximum peak value. Then, starting from the edges of items, it searches for a peak value specified as a percentage on a logarithmic scale. This mode can be useful when items have similar dynamics but are normalized to different loudness levels.

Absolute RMS (in DB)

This mode analyzes not the peak value, but the RMS within a specified window. This means it will ignore sudden volume spikes and stop at the point where the average RMS exceeds the specified threshold. It’s useful for longer audio material with uneven dynamics.

Relative RMS from max (in %)

The final mode is the most advanced. Like the relative peak mode, it first finds the maximum RMS value within the item, then searches from the edges for a point where the RMS exceeds a specified percentage of that maximum, calculated on a logarithmic scale. This mode is especially useful when the selected items have varying dynamics and loudness levels.

One more thing

• The script also features a real-time preview mode directly in the arrangement window, which is very convenient. However, when working with very long items, processing might take a bit more time.

• Additionally, it supports saving presets for different use cases.

• The script also comes with several versions for performing cuts without the GUI — either using the most recently applied settings or one of the first five saved presets.
