Why your audio is quiet on YouTube

You upload a video, play it next to somebody else's, and yours is the quiet one. So you go back, push the levels up, and export again. It arrives at exactly the level it arrived at before.

Platforms and players handle loudness differently. A louder export may be turned down, while excessive compression can remove useful dynamics. Check the destination and keep the voice clear within the mix.

Why is your video quieter than everybody else's?

Start by comparing the exported file with playback on YouTube at matched settings. Source level, mix balance, export gain and player controls can each affect what you hear.

What differs between two files arriving at the same measured level is what is inside them, and that is decided in the mix.

What does the platform do to your file?

It performs loudness normalisation, which is worth spelling out because the name hides how simple it is. The platform measures how loud your file is across the whole of its duration, rather than at its single loudest instant, using the same algorithm the industry measures with, ITU-R BS.1770. Then it turns your file down if it is louder than a target of its own. That target is not a single fixed number for everyone: some destinations publish theirs and some leave you to measure it, and it can differ between platforms and change over time. Because the platform re-levels your file on playback anyway, it is a figure to master towards with headroom rather than one to land on exactly, so what stays fixed is the measurement and the method, not the destination.

The reason is the viewer. Listeners should not have to reach for the volume control between videos, and before normalisation they often did.

YouTube's Stable Volume is a separate playback feature that evens out loud and quiet passages. It is on by default where available, but is not available on every video and is off for YouTube Music and official music videos. Check its state when comparing playback; it does not replace a careful master.

Why does making it louder not make it louder?

If both versions are reduced towards the same loudness reference, extra compression may bring little useful level advantage. It still changes the dynamics and perceived sound, so compare at a matched playback level.

The difference is what each of them spent getting there. One arrives with its quiet moments and its loud moments intact. The other arrives with everything at one height, having thrown away the differences that made it worth listening to.

Raising gain and compressing dynamics are different operations. Set an appropriate delivery level without flattening the recording merely to compete on loudness.

The cost of pushing

Dynamics help speech and music keep their shape. Excessive compression can make listening tiring, but a listener leaving is not by itself evidence that the audio caused it.

There is a second cost. Heavy squashing lifts everything, including the parts you did not mean to lift. Your room, your fan and your breath all come up to meet the voice, so a push for loudness quietly undoes the cleaning you did earlier in the day.

How do you check what happened?

Judge it after the upload, never before.

Upload it unlisted, watch it on a phone, and play it back to back with a video you think sounds right. Then go and change the mix rather than the export. Almost everybody makes this judgement in the editor, which is the one place in the chain where the platform's decision has not happened yet, so the editor is showing you a version nobody else will ever hear.

Do it once for a video you have already published and you will learn more about your own audio than any meter has taught you.

What to do instead of competing on level

Four things, in the order they pay.

1. Capture a clear voice with manageable background sound. 2. Balance quiet and loud passages while keeping useful expression. 3. Check loudness and true peaks against the destination's requirements. 4. Listen to the export and uploaded playback at comparable settings. If using a limiter, set it deliberately and check what it changes.

The expensive advice: do not buy a mastering plugin for this. Nothing added at the end of the chain buys back a voice recorded across a room, and most of them flatten the file while failing to.

Where the level stops being an export setting

When an upload sounds quiet, compare the original export and online playback first. If the speech itself is uneven, correct those passages in the mix, then check the new export before uploading.

That is the change the platform will not undo, because you have not asked it to be louder. You have asked it to be more evenly itself, and that is the version a viewer hears as loud.

Sources and evidence

What here is a platform fact and what is our own method. Platform behaviour was checked live on 28 August 2026.

Platform facts. Loudness is measured with ITU-R BS.1770-5 (2023), the industry algorithm. What platforms do with that measurement varies, and it is documented unevenly. Spotify publishes its targets on Spotify for Artists: about -14 LUFS by default, -11 for its loud setting and -19 for quiet, with a true-peak recommendation alongside. YouTube publishes no upload target in that way; its normalisation is established by measurement, and its Stable Volume feature is a separate, viewer-side playback control, on by default unless a viewer switches it off, not documentation of how uploads are levelled. So some destinations hand you a number and some leave you to measure it, and because each re-levels on playback anyway, the target is one to master towards with headroom rather than one to land on.

Our method. Mastering for intelligibility and headroom, then reading the playback after upload, is how this studio works rather than a rule any platform sets.
