How to make multiple audio files the same volume
Have you ever listened to a playlist or a podcast and found yourself constantly adjusting the volume because some tracks are too quiet and others are way too loud? This is a common problem when mixing audio files from different sources.
Our Audio Normalizer uses advanced LUFS algorithms to make two or more audio files the exact same volume. Unlike basic peak normalization, which just looks at the loudest single spike in the audio, our tool analyzes the perceived loudness over the entire track, perfectly matching human hearing.
Step-by-Step Guide
Click the upload button and select multiple audio files at once. You can choose a target level, but the default is -14 LUFS, which is the industry standard for streaming platforms like Spotify and YouTube.
Click process, and our engine will analyze each track and apply a studio-grade filter to equalize their volume. As each file finishes processing, click the download button to save your perfectly matched audio.
Frequently Asked Questions
Will this distort my audio?
No. We use a high-end dynamic algorithm that also limits the true peak. This guarantees that your audio will not clip or distort, even when we boost the volume of very quiet files.
Can I match the volume of 50 songs at once?
Yes! You can select dozens of tracks at the same time. The tool will process them in a queue, analyzing each one against the target LUFS target you selected.
Does this change the EQ or bass levels?
No. This tool only adjusts the overall gain (volume) of the track. The frequency balance and the actual mix of the song remain entirely untouched.
