Increase Volume: MP3 Booster

Increase Volume makes quiet audio files louder. Open a song, a voice recording, a podcast or a lecture, raise the volume up to 200%, shape the sound with the equalizer, and save a louder copy you can share anywhere.

Everything is processed on your phone. Your audio is never uploaded.

BOOST AUDIO VOLUME
• Increase the volume of an audio file up to 200%
• Fix recordings that are too quiet to hear
• Make MP3s, voice notes and podcasts louder before you share them
• Preview the boosted sound before you save it

5-BAND EQUALIZER
• Adjust five bands from 60 Hz to 14 kHz
• Add low end with the 60 Hz band or make voices clearer in the mids
• Presets for Rock, Jazz, Hip-Hop, Classical and Electronic

SAVE AND SHARE
• Export the boosted audio as a WAV file
• Share it by email, messenger or cloud storage
• Keep your original file untouched

HOW IT WORKS
1. Open an audio file from your phone
2. Set the volume boost and the equalizer
3. Play it back, then export and share the louder version

GREAT FOR
• Quiet voice recordings and interviews
• Lectures and meeting recordings
• Podcasts and audiobooks
• Songs that are mixed too low
• Audio you want to send to someone else

GOOD TO KNOW
Increase Volume works on audio files you open in the app. It does not change your phone's system volume or the sound of other apps. Very high boost levels can cause distortion, so raise the volume step by step.

FREE AND PREMIUM
You can boost and play audio for free and export your first file. Premium removes the export limit.

QUESTIONS
How do I make an MP3 louder?
Open the MP3 in Increase Volume, move the volume slider above 100%, play it to check, then export.

Does it upload my files?
No. All processing happens on your device.

Listening at high volume for a long time can damage your hearing. Increase the volume gradually.
