Overview

Clean unwanted noise from an audio file with FFmpeg filters, including high-pass filtering and adjustable noise reduction, then export the result as WAV, MP3, FLAC, AAC, OGG, or M4A.

When to use

Remove low-frequency rumble, hum, and other background noise from recordings.
Improve the clarity of voice recordings, interviews, podcasts, or spoken audio.
Adjust noise reduction and output gain before exporting cleaned audio in your preferred format.

How it works

1Upload one supported audio file in MP3, WAV, FLAC, AAC, OGG, MP4, or M4A format, up to 50 MB.
2Set the high-pass frequency to reduce low-frequency rumble and hum.
3Adjust the noise reduction level from -10 dB to -50 dB, where more negative values apply stronger reduction.
4Choose an output volume gain and export the processed audio as WAV, MP3, FLAC, AAC, OGG, or M4A.

Use cases

Clean spoken-word recordings by reducing background noise and low-frequency rumble.
Prepare interview or podcast audio for clearer listening.
Restore more consistent volume after applying noise reduction.

Examples

1. Clean a voice interview recording

Podcast editor

Background

A podcast editor has an interview recording with low background rumble and a slightly reduced volume after cleanup.

Problem

The recording needs less low-frequency noise while keeping the spoken voice clear and audible.

How to use

Upload the interview audio, set the high-pass frequency to 80 Hz, use moderate noise reduction, and increase the output volume slightly.

High-pass frequency: 80 Hz; noise reduction: -25 dB; output volume gain: 1.5x; output format: WAV.

Outcome

The exported WAV file has reduced low-frequency rumble and a compensated output level.

2. Reduce noise in a field recording

Audio producer

Background

An audio producer recorded spoken material outdoors and needs to reduce a persistent background noise before editing.

Problem

The source audio contains noticeable noise that distracts from the main recording.

How to use

Upload the source file, increase the noise reduction strength, select an appropriate high-pass frequency, and export the cleaned result.

FAQ

What audio files can I upload?

You can upload MP3, WAV, FLAC, AAC, OGG, MP4, or M4A audio files up to 50 MB.

What does the high-pass frequency control do?

It filters low-frequency rumble and hum. Higher values remove more bass frequencies.

How strong can the noise reduction be?

The noise reduction range is -10 dB to -50 dB. More negative values apply stronger reduction.

Can I increase the processed audio volume?

Yes. Set the output volume gain from 0.5x to 3x to compensate for volume loss.

Which output formats are available?

You can export cleaned audio as WAV, MP3, FLAC, AAC, OGG, or M4A.

High-pass frequency: 120 Hz; noise reduction: -35 dB; output volume gain: 1.7x; output format: FLAC.

3. Prepare a compact cleaned audio file

Content creator

Background

A content creator has a noisy voice clip and needs a processed version in a commonly supported compressed format.

Problem

The original clip contains background noise and is not ready for publication.

How to use

Upload the clip, apply high-pass filtering and noise reduction, then choose MP3 as the output format.

High-pass frequency: 100 Hz; noise reduction: -25 dB; output volume gain: 1.5x; output format: MP3.

Outcome

The tool produces an MP3 version with reduced background noise and adjusted output volume.
