## Overview

Cleans remote podcast, interview, lecture, and call recordings with a practical de-reverb chain: high-pass cleanup, low-pass taming, low-mid room cuts, FFT denoise, gentle compression, and optional dialogue focus. It is not an ML source separator, but it is fast, offline, and predictable for everyday voice rescue.

## Inputs

- **Audio File** (file): Select an audio file
- **Rescue Preset** (select)
- **Dereverb Strength** (range)
- **Voice Focus** (checkbox)
- **Preserve Natural Room Tone** (checkbox)
- **Output Format** (select)

## When to use

- When a remote podcast guest records in an untreated room with noticeable echo and boxiness.
- When cleaning up online lecture or interview recordings that suffer from background noise and dull vocal clarity.
- When you need a fast, predictable, and offline audio restoration tool without relying on heavy machine learning models.

## How it works

- Upload your audio file in any standard format up to 100MB.
- Select a rescue preset, adjust the dereverb strength slider, and toggle voice focus or room tone preservation options.
- Choose your preferred output format, such as MP3, WAV, FLAC, M4A, or OGG.
- Process the file to apply the multi-stage cleanup chain and download the restored audio.

## Use cases

- Polishing remote podcast interviews recorded on laptop microphones in echoey rooms.
- Improving the intelligibility of recorded online lectures and webinars for students.
- Cleaning up voice samples and field recordings before importing them into a digital audio workstation.

## Frequently asked questions

### Does this tool use AI or machine learning to separate voices?

No, it uses a predictable, offline DSP chain featuring filters, FFT denoise, and compression rather than ML source separation.

### What audio file formats are supported for input and output?

You can upload standard audio files up to 100MB, and export the processed audio as MP3, WAV, FLAC, M4A, or OGG.

### What does the Voice Focus option do?

Voice Focus applies targeted equalization and filtering to emphasize the dialogue frequencies and reduce surrounding distractions.

### Can I keep some of the original background atmosphere?

Yes, enabling the 'Preserve Natural Room Tone' option prevents the denoiser from completely silencing the natural background environment.

### How do I fix a recording with severe echo?

Select the 'Echoey Room Voice' or 'Strong Rescue' preset and increase the 'Dereverb Strength' slider toward its maximum value.
