Boost Audio Volume Online: Make Quiet Recordings Louder
Nothing ruins a listening experience like straining to hear a whisper-quiet podcast or having one song in your playlist sound significantly lower than the rest.
If you have an audio file that is just too quiet, you need a Volume Booster.
Why Is My Audio Quiet?
- Poor Microphone Placement: The mic was too far from the speaker.
- Low Input Gain: The recording level was set too low during capture.
- Dynamic Range: The file has very loud peaks but quiet averages, causing playback devices to lower the overall volume.
How Volume Boosting Works
Our tool applies "gain" to the digital signal. Think of it like a multiplier.
- 1x: Original volume.
- 2x: Twice as loud.
Warning: Clipping and Distortion
You can't just maximize volume forever. If the sound wave hits the digital "ceiling" (0dB), it gets chopped off, creating harsh distortion known as clipping.
- Our Solution: We use intelligent limiting algorithms to boost the perceived loudness while preventing harsh distortion as much as possible.
Step-by-Step Guide
