To enhance vocals with a modulated, ethereal quality for podcasts or songs.
For sound design in film or games to create dynamic, atmospheric audio textures.

How it works

1Upload an audio file in a supported format like MP3, WAV, or AAC.
2Adjust parameters such as input gain, output gain, delay, decay, speed, and phase type (Triangle or Sine).
3Select the desired output format from options including MP3, WAV, FLAC, and more.
4Process the file to apply the phaser effect and download the result.

Use cases

Enhancing guitar solos in rock music with a classic phaser sweep for added depth.

Examples

1. Guitar Solo Enhancement

Music Producer

Background

A producer is working on a rock track and wants to add movement to a static guitar solo.

Problem

The solo sounds flat and lacks the dynamic, swirling quality needed for the mix.

How to use

Upload the guitar solo audio file, set speed to 0.5 Hz for a slow sweep, select Sine phase type, and output as WAV.

{"inGain": 0.4, "outGain": 0.74, "delayMs": 3, "decay": 0.4, "speedHz": 0.5, "type": "s", "outputFormat": "wav"}

Outcome

The processed solo has a rich, spacey effect that adds expressiveness and fits seamlessly into the track.

2. Vocal Modulation for Film Score

Sound Designer

Background

A sound designer is creating an eerie atmosphere for a horror film scene using vocal samples.

Problem

The vocals need to sound distorted and otherworldly to enhance the scene's tension.

How to use

Upload the vocal audio, increase decay to 0.8 for a longer trail, set speed to 1 Hz for faster modulation, choose Triangle phase type, and output in AAC format.
