Volume Booster FAQ
Are my audio files uploaded?
No. The booster runs locally in your browser, so your audio is not sent to NeuralSound servers.
Can I make audio quieter?
No. V1 is boost-only and starts at 100%, which preserves the original volume.
Will boosting cause distortion?
Large boosts can still sound aggressive. Enable limiter protection to reduce clipping risk, or leave it off when you want the raw boosted signal.
Which format should I choose?
MP3 is the best default for compatibility. M4A and OGG are available for specific playback or web workflows.
