## Overview

Creates precise delay effects commonly used in music production. Adjustable delay time, feedback, and wet/dry mix for slapback, dotted, or rhythmic delays.

## Inputs

- **Audio File** (file): Select an audio file
- **Delay Time (ms)** (number): Time between original sound and delayed repetition. Common values: 100-500ms for slapback, 250-750ms for rhythmic delays.
- **Feedback (0-0.95)** (range): Controls how much delayed sound feeds back into itself. Higher values create longer decay tails.
- **Wet/Dry Mix (0-1.0)** (range): Balance between dry (original) and wet (delayed) signal. 0 = dry only, 0.5 = equal mix, 1.0 = wet only.
- **Tempo Sync** (select): Sync delay time to musical tempo. Useful for rhythmic delays in music production.
- **Output Format** (select)

## When to use

- When adding a slapback delay to vocals or instruments for a vintage sound.
- For creating tempo-synced rhythmic delays in music tracks.
- To experiment with feedback settings for long decay tails and ambient effects.

## How it works

- Upload your audio file in a supported format.
- Set the delay time in milliseconds or use tempo sync for musical timing.
- Adjust feedback and wet/dry mix to shape the delay effect.
- Choose an output format and download the processed audio file.

## Use cases

- Enhancing vocal tracks with a slapback delay for added presence.
- Adding depth to guitar solos with tempo-synced delays.
- Creating ambient textures with high feedback and wet mix settings.

## Frequently asked questions

### What delay time should I use for a slapback effect?

Slapback delays typically use 100-500ms for a quick, subtle repeat.

### How does the feedback parameter work?

Feedback controls how much of the delayed signal is fed back; higher values create longer echoes.

### Can I sync the delay to my song's BPM?

Yes, use the tempo sync option to set delay based on quarter, eighth, or other note values.

### What audio formats can I upload?

You can upload any audio file supported by your browser, such as MP3, WAV, etc.

### Is there a limit on file size?

Yes, the audio file must be under 200MB.
