Increase Audio Volume Online - Free
Make a quiet recording louder by a specific dB amount. The tool multiplies every sample by the gain value you set. +6 dB roughly doubles the perceived loudness. You can boost the entire file or just a selected region.

Problems This Tool Solves
My recording is too quiet but boosting makes it distort
A single loud spike limits how much you can boost. Use the Compressor to tame peaks first, then boost volume safely.
Background hiss gets louder when I increase volume
Volume boost amplifies everything, including noise. Run Noise Removal first, then boost the cleaned audio.
My podcast is quieter than other shows on the same platform
Platforms normalize to loudness standards (LUFS), not peak volume. Use Compressor + Normalize for consistent perceived loudness.
Common Use Cases
Boost a quiet voice memo
Recorded too far from the mic? A +6 to +9 dB boost can bring a faint recording to a usable level.
Match volume for social sharing
Make a clip loud enough to compete with other audio on Instagram, TikTok, or YouTube.
Raise one section of a recording
Select a quiet passage and boost just that part without affecting the rest.
Fix a low interview recording
Phone interviews and meeting recordings often come out too quiet. Boost by +3 to +6 dB to make the speech clear.
Boost a Twitch or Discord notification sound
Stream alerts and notification sounds need to punch through gameplay audio. A +6 to +9 dB boost makes them audible without being jarring.
How to Increase Audio Volume Online
- Upload your audio file by dropping it into the editor or clicking Upload.
- Set the volume boost amount in dB. Start with +3 to +6 dB.
- Click Apply to increase the volume. Preview the result before exporting.
- Export as WAV for full quality or MP3 for a smaller file.
Increase Volume vs Normalize - Different Approaches
Increase Volume
You set the exact dB amount to add. Manual control. Can cause clipping if you boost too much.
Best for: boosting by a known amount, adjusting a specific section, quick loudness fixNormalize
Automatically calculates the boost needed to bring the loudest peak to your target level. No clipping risk.
Best for: maximizing volume safely, matching levels across files, preparing for exportCompressor
Reduces the gap between loud and quiet parts. Does not simply make everything louder.
Best for: evening out volume in podcasts, taming peaks, making speech more consistentSafe Boost Ranges by Use Case
| Scenario | Starting boost | Watch for |
|---|---|---|
| Slightly quiet recording | +3 to +6 dB | Check peaks stay below 0 dBFS |
| Very quiet recording | +6 to +12 dB | Background noise gets louder too. Consider noise removal first. |
| Match another file’s volume | +1 to +3 dB | Preview both files to compare |
| Notification / alert sound | +6 to +9 dB | Keep short. Distortion is more noticeable on alerts. |
Quick Tips
- Start small. +3 dB is a noticeable bump. +6 dB roughly doubles perceived loudness.
- If the audio clips (distorts) after boosting, use Normalize instead. It calculates the maximum safe boost automatically.
- Boosting also amplifies background noise. For very quiet recordings, run Noise Removal before boosting.
- You can use negative dB values to reduce volume. Handy for taming a loud section before merging.
Common Misconceptions
Myth: Louder is always better
Reality: Digital audio has a hard ceiling at 0 dBFS. Pushing past it causes clipping distortion. Perceived loudness depends on dynamic range, not just peak level.
Myth: You can go above 0 dB without problems
Reality: Samples above 0 dBFS are clipped flat, creating harsh buzzing distortion. Use a limiter or normalize to keep peaks safely below 0 dB.
Common Problems and Fixes
Audio sounds distorted after boosting
You boosted past 0 dBFS and the audio is clipping. Undo, then either reduce the boost amount or use Normalize to bring the volume up without exceeding the limit.
Background hiss got much louder
Volume boost amplifies everything, including noise. Use the Noise Removal tool first, then boost the cleaned audio.
One loud spike prevents me from boosting enough
A single loud peak (laugh, cough, door slam) limits the room for boosting. Use the Compressor to tame that peak first, then boost volume.

Frequently Asked Questions
How much should I boost?
Start with +3 to +6 dB and preview. +6 dB roughly doubles perceived loudness. If the audio distorts, you have gone too far. Use Normalize instead for automatic safe leveling.
What is clipping and how do I avoid it?
Clipping happens when the audio exceeds the maximum digital level (0 dBFS). The waveform gets chopped flat, causing a harsh buzzing distortion. To avoid it, boost in small steps and preview, or use Normalize which cannot clip.
Should I boost volume or normalize?
If you know exactly how much louder you need the audio, use Volume. If you want the audio as loud as possible without distortion, use Normalize. For uneven recordings where some parts are loud and others quiet, use the Compressor.
Will boosting an MP3 make the quality worse?
The boost itself does not degrade quality. But if you export back to MP3, the file gets re-encoded, which adds a small amount of compression artifacts. Export at the same or higher bitrate as the original.
What is the difference between volume and loudness?
Volume is the raw signal level (measured in dBFS). Loudness is how loud something sounds to your ears (measured in LUFS). A recording with one loud spike and quiet speech has high peak volume but low perceived loudness. To make something sound louder, you often need compression before boosting.
One loud spike prevents me from boosting the rest
A single loud peak (laugh, cough, door slam) limits how much you can boost before clipping. Use the Compressor first to tame that peak, then boost the entire file safely.
Will boosting an MP3 make the quality worse?
The volume boost itself does not degrade the audio. But exporting back to MP3 re-encodes the file, which adds a small layer of compression artifacts. Export at the same or higher bitrate as the original to keep the difference negligible.
