Audio for YouTube Creators

YouTube measures the integrated loudness of your uploaded audio and normalizes it to approximately -14 LUFS for desktop and -13 LUFS for mobile. If your audio is louder than the target, YouTube turns it down. If it is quieter, it gets turned up. This means there is no benefit to uploading audio that has been heavily limited to -8 or -10 LUFS — YouTube will turn it down, and you will have sacrificed dynamic range for nothing. Target -14 LUFS for YouTube uploads. Use a loudness meter in your editing software (Audacity, Adobe Premiere, DaVinci Resolve) to measure integrated loudness before export.

YouTube accepts AAC, MP3, WAV, FLAC, and most other audio formats inside video containers. The recommended approach is to embed AAC audio at 320 kbps inside an MP4 container. AAC is what YouTube re-encodes to anyway for delivery — uploading AAC avoids a double-transcode from MP3 or WAV. For speech-heavy content (tutorials, vlogs, educational videos), 128 kbps AAC is sufficient. For music-heavy content or videos where audio quality is the primary content (music videos, audio reviews), use 256-320 kbps AAC. Never deliver at below 128 kbps for any public YouTube content.

The most common audio mistake on YouTube is poor recording quality. A mid-range USB microphone (Rode NT-USB Mini, Blue Yeti, Elgato Wave 3) dramatically improves audio quality compared to a laptop built-in microphone. Record in a treated space — a room with carpets, curtains, and soft furniture reduces echo. Position the microphone 15-20 cm from your mouth. Use a pop filter or foam windscreen. Record dry (no reverb or processing), then apply processing in post. Leave headroom of -6 to -3 dBFS on your recorded peaks to give yourself room to work with in post-processing.

A simple processing chain for YouTube voiceover: high-pass filter at 80-100 Hz (remove rumble), gentle noise reduction (reduce constant background noise by 6-10 dB), compression (2:1 to 3:1 ratio, fast attack, medium release, 4-6 dB gain reduction), and a limiter at -1 dBFS true peak as a safety ceiling. Then measure and adjust to hit -14 LUFS integrated. Most modern video editors (DaVinci Resolve, Adobe Premiere) include loudness meters. Audacity is free and includes the Loudness Normalization effect that targets LUFS directly. For music, use the same processing chain but set a higher compression ratio for the limiter stage.

Room echo and reverb: a reverberant room makes speech sound distant and muddy — treat the room or use a reflection filter behind the microphone. Over-compression: heavy compression flattens your voice and sounds fatiguing over time. Uploading too-loud masters: they get normalized down, sacrificing dynamic range. Ignoring background noise: HVAC hum, keyboard clicks, and mouse clicks are all audible on a sensitive microphone. Inconsistent levels across a video: normalize each segment to the same LUFS before cutting. Music mixing too loud relative to voice: background music should be 10-20 dB quieter than the primary speaker. Mono audio: YouTube expects stereo — a mono audio track plays only from the left speaker unless properly processed.
