Frequently Asked Questions
View All FAQsIs my audio track uploaded to a server when normalizing?
No. Audio peak scanning and gain processing execute 100% locally in your browser memory.
What is the difference between Peak Normalization and LUFS Normalization?
Peak normalization scales maximum volume to 0 dBFS without clipping, while LUFS normalization balances perceived loudness for streaming platforms.
Will normalizing audio introduce distortion?
No. Peak limiting guardrails prevent digital clipping and inter-sample distortion artifacts.
Can I normalize multiple audio files to the same volume?
Yes. Normalizing audio tracks ensures consistent volume levels across different voice takes or playlist files.
