Make the audio sound better

Speech Enhancement API

Like Adobe Podcast Enhance — but via API. Loudness normalization, level balancing across speakers, EQ, and dereverb.

Raw recording — dull and uneven

0:00 / 0:00

Same recording — raw vs. studio-enhanced. Switch mid-playback.

How it works

01

Get your API key

Create an account and copy your API key from the Cleanvoice dashboard.

02

Install the SDK

Use the official Python or JavaScript SDK. Alternatively, call the REST API directly.

03

Submit your file

Use a local file or url of your audio/video we should process.

04

Poll or Webhook

Jobs run async. SDKs handle polling automatically, alternatively use our webhook to upload the result to your s3 storage.

Example

Format

import { Cleanvoice } from '@cleanvoice/cleanvoice-sdk';const client = new Cleanvoice({ apiKey: process.env.CLEANVOICE_API_KEY });// Remove fillers, dead air, mouth sounds + denoise and normalize.const result = await client.process('https://example.com/episode.mp3', {  fillers: true,  long_silences: true,  mouth_sounds: true,  remove_noise: true,  normalize: true,});console.log('Cleaned audio:', result.audio.url);await result.audio.download('cleaned.mp3');
