About This Tool

Audio Volume Changer — Adjust Volume Levels Easily

Audio volume that is too quiet, too loud, or inconsistent between files is a common problem. Our Audio Volume Changer lets you precisely increase or decrease audio volume, normalize levels, or adjust gain — all without complicated audio editing software.

Volume Adjustment Modes

Increase volume: Boost the audio level by a specified number of decibels (dB). Ideal for quiet recordings that need amplification.

Decrease volume: Reduce the audio level for tracks that are too loud or clipping.

Normalize: Automatically set the peak volume to a standard reference level (typically -1 dBFS or 0 dBFS) without distortion. Normalization makes audio as loud as possible without clipping.

Loudness normalization (LUFS): Match audio to broadcast and streaming standards:

-14 LUFS for YouTube and Spotify
-16 LUFS for Apple Podcasts
-23 LUFS for broadcast television (EBU R128)

Custom dB adjustment: Enter any positive (louder) or negative (quieter) dB value for precise control.

Use Cases

Podcasters: Normalize your voice recordings so all episodes have consistent loudness that meets platform requirements.

Video creators: Adjust background music volume to be significantly quieter than dialogue so it doesn't compete with speech.

Musicians: Adjust demo tracks to a reference level before sharing with collaborators.

Archiving: Normalize old recordings that were captured at inconsistent volume levels.

Audio sync: Match the volume of multiple recordings before merging them into a single track.

Understanding Decibels

Decibels (dB) measure audio levels on a logarithmic scale:

+3 dB doubles the perceived loudness
+6 dB doubles the power (amplitude)
-10 dB makes audio about half as loud to human ears

Clipping Prevention

The tool warns when the requested volume increase would cause clipping (distortion above 0 dBFS). Use the limiter option to automatically prevent clipping while maximizing volume.

❓ Frequently Asked Questions

Normalization adjusts the volume of an audio file so its peak level reaches a reference point (usually -1 dBFS or 0 dBFS). This makes the audio as loud as possible without causing distortion.

LUFS (Loudness Units Full Scale) measures perceived loudness. Streaming platforms like Spotify (-14 LUFS), YouTube (-14 LUFS), and Apple Podcasts (-16 LUFS) normalize uploads to their target levels. Matching these targets avoids your content being turned down automatically.

You can boost by 1-20 dB. Note that increasing above 0 dBFS causes clipping distortion. The tool warns when boosting would exceed safe limits.

Clipping occurs when the audio signal exceeds 0 dBFS, causing distortion. Enable the limiter option to automatically prevent clipping while maximizing volume.

Yes. Upload multiple files and apply the same normalization settings to all of them in one operation.

Peak normalization sets the loudest moment to a reference level. RMS normalization targets the average loudness. LUFS is an advanced form of average normalization that correlates closely with human perception.
