## Overview

Creates discrete echo repetitions with adjustable delay, feedback, and mix. Simulates environments like canyons, tunnels, or large empty spaces.

## Inputs

- **Audio File** (file): Select an audio file
- **Echo Delay (ms)** (number): Time between original sound and first echo. Longer delays create dramatic canyon-like effects.
- **Feedback (0.1-0.9)** (range): Controls how much each echo feeds back into the next. Higher values = more echoes.
- **Echo Mix (0.1-0.8)** (range): Controls the volume of echoes relative to original sound. Lower values = subtle effect.
- **Number of Echoes (1-10)** (number): How many distinct echoes to generate. More echoes = longer decay tail.
- **Output Format** (select)

## When to use

- When you need to create dramatic echo effects for music production or sound design.
- To simulate acoustic spaces such as large halls, tunnels, or outdoor environments in audio.
- For adding depth and dimension to vocal recordings, podcasts, or video game sound effects.

## How it works

- Upload your audio file in a supported format like MP3, WAV, or AAC.
- Set the echo delay in milliseconds to control the time between the original sound and echoes.
- Adjust the feedback to determine how many echoes are generated and their decay.
- Choose the mix level to balance echo volume with the original, select the number of echoes, and pick an output format.

## Use cases

- Enhancing podcast audio with environmental echo effects for storytelling segments.
- Creating slapback echo in music production to achieve a vintage or retro sound.
- Designing sound effects for video games or films to simulate specific acoustic spaces like caves or stadiums.

## Frequently asked questions

### What audio file formats are supported for upload?

You can upload audio files in common formats such as MP3, WAV, AAC, M4A, OGG, Opus, and FLAC, as specified in the tool options.

### How can I make the echo effect more intense?

Increase the feedback value and the number of echoes to create a longer decay tail with more repetitions.

### Is real-time audio processing available?

No, this tool processes uploaded files and returns a new audio file with the echo effect applied; it does not support real-time preview.

### What is the maximum file size I can upload?

The maximum file size is 200 MB, as indicated by the file input limit in the tool options.

### How many distinct echoes can I generate?

You can generate between 1 and 10 distinct echoes, adjustable via the echo count parameter.
