Overview

The Audio Chorus tool applies a chorus effect to audio files, using ffmpeg to add multiple modulated delay voices that thicken and enrich the sound. It supports various input formats and allows customization of chorus parameters for precise audio enhancement.

When to use

When you need to add depth and width to vocal tracks in music production.
To create a richer sound for podcast intros, background music, or video game audio.
When processing audio to achieve a modulated, layered effect for instruments or ambient sounds.

How it works

1Upload an audio file in a supported format, such as MP3, WAV, or AAC.
2Optionally configure the chorus voices by entering a JSON array with parameters like inGain, outGain, delay, decay, speed, and depth.
3Select the desired output format from options including MP3, AAC, OGG, FLAC, and WAV.
4The tool processes the audio using ffmpeg's chorus effect and provides a downloadable file.

Use cases

Enhancing vocal harmonies in home studio recordings for a fuller sound.
Adding modulation to electric guitar tracks in indie or rock music production.
Creating atmospheric soundscapes for meditation apps or video game backgrounds.

Examples

1. Thicken Pop Vocal Backing

Music Producer

Background

A producer is mixing a pop song and wants the backing vocals to sound more present and layered.

Problem

The raw vocal tracks are thin and lack depth in the mix.

How to use

Upload the vocal audio file, use the default voices configuration or adjust parameters for more depth, and select WAV output for high quality.

[{"inGain":0.5,"outGain":0.9,"delay":40,"decay":0.4,"speed":0.25,"depth":2}]

Outcome

The processed vocals have a rich, chorus effect that blends seamlessly with the lead vocals.

2. Add Dreamy Chorus to Guitar

Background

A guitarist is recording an acoustic track and wants to apply a subtle chorus for a warm, ambient tone.

Problem

The guitar sound is too dry and needs modulation to fit the song's mood.

How to use

Upload the guitar audio file, configure voices with slower speed and moderate depth, and output in MP3 for easy sharing.

Outcome

The guitar now features a smooth, modulated chorus that enhances the track's atmosphere.
