What is -14 LUFS?

-14 LUFS is the loudness standard for streaming platforms (Spotify, YouTube, Apple Music). Normalizing to -14 LUFS ensures consistent playback volume.

How many dB should I boost?

+6 dB doubles perceived loudness. +10 dB is a significant increase. Above +20 dB risks clipping without compression.

What is audio normalization?

Normalization raises the overall volume so the loudest peak reaches a target level (e.g., -1 dBFS) without distortion.

Can I increase MP3 volume without losing quality?

The output is a lossless WAV file, so no compression quality is lost during boosting.
