  • •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.

Examples

1. Slapback Delay for Vocals

Music Producer
Background
A producer is mixing a vocal track and wants to add a classic slapback delay for warmth.
Problem
The vocals sound dry and need more character.
How to Use
Upload the vocal file, set delay time to 150ms, feedback to 0.2, mix to 0.3, and output as MP3.
Outcome
The vocals now have a subtle delay that adds depth and a vintage feel.

2. Tempo-Synced Delay for Guitar

Guitarist
Background
A guitarist is recording a solo and needs the delay to match the song's tempo.
Problem
The delay effect is out of sync with the music.
How to Use
Upload the guitar audio, select tempo sync to '1/8' for eighth-note delays, set feedback to 0.5, mix to 0.4, and output as WAV.
Outcome
The guitar solo has a rhythmic delay that enhances the groove and timing.

FAQ

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.
