Make your audio files louder and clearer.
It often happens that a voice recording, a phone interview, or a podcast is barely audible due to a poorly adjusted microphone. Our audio amplifier re-encodes your audio file by multiplying the amplitude of the sound waves.
You can double or even triple the baseline volume. Since this process runs entirely within your browser's CPU, your personal audio files stay strictly on your device, completely safe from data leaks.
Import the specific audio file (podcast, voice memo) that sounds too quiet during playback.
Choose how much you want to amplify the sound waves (x1.5, x2, or x3).
Our local algorithm recalculates the file's amplitude and prepares it for immediate download.
It often happens that a voice recording, phone interview, or podcast is barely audible because the microphone was placed too far away, incorrectly set up, or the person was whispering.
Our sound amplifier mathematically re-encodes your audio file by multiplying the overall amplitude of the sound waves. This 'zero upload' processing guarantees that your private conversations stay strictly on your device, completely protected against data leaks.
By drastically increasing the volume, you risk saturating the audio (Clipping) if the file already contains sections that are somewhat loud. This will result in a crackling and distorted sound. It is generally safer to try a moderate boost (x1.5) first.
Yes, this is a global mathematical amplification. While the voice becomes louder, ambient wind noise or air conditioning hums will be boosted too. If your audio track has a heavy hiss, we recommend using our 'Noise Reducer' tool before amplifying it.
