Will increasing volume cause distortion?

SnapOtter includes clipping detection to warn you if the gain would cause distortion. Moderate boosts on quiet recordings are generally safe. If clipping occurs, consider using the normalize tool instead. Processing happens on your own server.

How is this different from normalization?

Volume adjust applies a fixed gain to the entire file uniformly. Normalization analyzes the audio and adjusts dynamically to reach a target loudness. Use volume adjust for simple corrections. Both tools run locally on your server.

Can I adjust volume for specific sections only?

This tool adjusts the volume of the entire file by a fixed amount. For section-specific changes, trim the file first, adjust each part, then merge. All processing happens on your self-hosted instance.

Volume Adjust

Increase or decrease the volume of an audio file by a fixed decibel gain. Useful for boosting quiet recordings or reducing loud audio to a comfortable level. SnapOtter processes the adjustment on your own server, keeping your audio private.
