About Audio Volume Booster
OptiPix Audio Volume Booster lets you adjust the volume of any audio file from -20dB to +20dB directly in your browser. Use the auto-normalize feature (loudnorm) to bring your audio to consistent broadcast levels. Enable the limiter to prevent clipping when boosting volume. Visual warnings appear if your boost level risks distortion. Export in MP3, WAV, OGG, FLAC, or AAC with adjustable bitrate. Uses FFmpeg.wasm for professional-grade audio processing.
How It Works
The tool uses FFmpeg.wasm's volume filter for manual adjustment, loudnorm filter for automatic normalization, and alimiter filter to prevent clipping. All processing runs locally.
