YouTube normalizes uploads to -14 LUFS, so anything you publish too quiet gets boosted (and anything too loud gets pulled down). Matching your levels before upload gives you control over the result. Beyond that, YouTube is forgiving on input format. But a clean WAV master uploaded once beats a re-encoded MP3 uploaded multiple times.
Compress WAV to high-quality 320 kbps MP3.
Convert lossless FLAC to portable MP3 for any player.
Turn AAC files into MP3 for universal playback.
Trim silence and dead air from any audio clip.
Stitch multiple audio files into one seamless track.
Normalize loudness to a consistent target level.
Explore acoustic indicators. Not proof of AI origin.
Create lyric videos with editable timing.
-14 LUFS integrated. YouTube applies this normalization automatically; pre-mastering to that target means your video plays back at the loudness you intended, not what their algorithm decides.
WAV preserves the most quality through YouTube's re-encoding. If your video editor can't take WAV, an MP3 at 320 kbps is essentially the same in practice. Avoid going below 256 kbps. YouTube's encoder will compound the loss.
