How do I make an audio file louder?
Updated:
Open the Volume Booster, drop the file and press Apply and save. It normalizes the audio and raises it by 6 dB to start, and a limiter stops the loudest parts from distorting. The Volume Booster is part of AudioCutter Pro.
What are the steps?
- Open the Volume Booster (Pro) and drop an MP3, WAV, M4A or other audio file.
- Keep Normalize first on and choose a target: loudest peak at −1 dB, −14 LUFS for Spotify and YouTube, or −16 LUFS for podcasts.
- Move the Volume slider if you want more; it goes up to +24 dB.
- Press Preview 10 seconds to hear the result from the playhead.
- Press Apply and save, then download the louder file.
Will boosting the volume distort the sound?
The limiter turns down only the loudest moments, so nothing clips. Very large boosts, above about +12 dB, squash the dynamics and can sound flat, so preview before saving.
What is the difference between normalizing and boosting?
Normalizing sets the whole file to a target, such as its loudest peak at −1 dB or an average of −14 LUFS. Boosting then adds level on top, with the limiter catching the peaks.
How do I make a quiet voice recording clearer?
Tick “Remove background noise (best for voices)” next to the volume. Removing hiss and hum first means the boost raises your voice, not the noise.
Can I make audio louder on my phone?
Yes. The Volume Booster runs in Safari and Chrome on phones. The file is processed by the browser and saved back to your downloads.
Can I make audio quieter?
Yes. Turn Normalize off and move the slider below 0 dB.
