What is an Audio Reverb Processor?

A lightweight, privacy-secure online tool designed to add professional-grade reverb effects to audio. No software installation or file uploads required—all operations occur locally within your browser, eliminating any risk of privacy leaks. Features multiple scene presets (e.g., Vocal Reverb, Cathedral Reverb) and advanced parameter customization capabilities, catering to both beginners and professional users.

Key Features

  1. Multi-Scene Presets: Instantly apply 9 professional reverb effects, covering everyday to specialized scenarios.
  2. Deep Parameter Customization: Adjust core parameters like Reverb Strength, Room Scale, HF Damping, and more.
  3. Local Processing: Audio files never leave your device; processing is fast (e.g., 8 seconds for a 3-minute track).
  4. Real-Time Preview & Compare: Audition segments and instantly compare original vs. processed effects.
  5. Strong Format Compatibility: Supports input/output of mainstream formats (MP3, WAV, AAC).

How to Use?

1. Upload Audio File

  • Click “Choose File” or drag a local audio file (MP3/WAV/AAC) to the workspace.

2. Select & Customize Reverb Effect

  • Choose Preset: Quickly match scenarios from presets (e.g., Vocal Reverb, Cathedral Reverb).
  • Basic Adjustment: Drag Reverberance to fine-tune intensity.
  • Advanced Settings: Click Show Advanced Settings to customize:
    • Room Scale: Simulates room size (higher = more spacious).
    • HF Damping: Accelerates high-frequency decay (higher = softer sound).
    • Pre Delay: Time gap between dry sound and reverb onset (higher = stronger spatial depth).
    • Stereo Depth: Difference in reverb between L/R channels (higher = wider soundstage).
    • Wet Gain: Dry/wet signal volume ratio (higher = more pronounced effect).
  • Click Process to start.

3. Preview & Download

  • Preview & Compare: Click the waveform to audition original/processed segments.
  • Export: Select output format (MP3/WAV) and click “Download” to save locally.

Preset Descriptions

Parameters are calibrated based on acoustic characteristics (e.g., Bathroom Reverb’s high reflectivity, Cathedral Reverb’s long decay) for authentic scene reproduction.

PresetScenario Description
CustomFreely adjust all parameters.
Vocal ReverbMedium reverb + HF Damping for vocal clarity.
Bathroom ReverbHigh reflectivity, short reverb (simulates tiled-wall echoes).
Small Room ReverbShort reverb + low Room Scale for intimacy (e.g., bedroom).
Medium Room ReverbBalanced reverb and space, ideal for dialogue or solo instruments.
Large Room ReverbLong reverb + high Room Scale (simulates concert hall acoustics).
Church Hall ReverbStrong reverb + Pre Delay for solemn ambience.
Cathedral ReverbExtreme duration (>3s) + high Stereo Depth (simulates dome resonance).
Plate ReverbDense, uniform decay from metal plates (ideal for vintage vocals/drums).
Spring ReverbUnique “bouncy” tone from mechanical springs (common in guitar effects).
