LUFS measures perceived loudness. -16 LUFS is the standard for podcasts and YouTube. Spotify uses -14, broadcast TV uses -24. We target -16 as the best general-purpose level.

No. MiOffice uses dynamic loudness normalization, not simple gain. It adjusts the overall level without clipping peaks.

This is exactly what it is built for. Normalize to -16 LUFS and your podcast will sound consistent across Apple Podcasts, Spotify, and YouTube.

MP3, WAV, M4A, AAC, OGG, FLAC, and video files (MP4, MOV, MKV, WebM) up to 2GB.

Currently one file at a time. Each file is normalized to the same -16 LUFS target for consistent output across all your content.

Yes. The audio is processed at full quality. For lossless formats like WAV and FLAC, the output stays lossless.
