[Feature] Option to exclude DRC audio from YouTube #412

Closed Comitant closed 3 months ago

Comitant commented 3 months ago

YouTube has new formats for DRC audio. Unfortunately, MPC-BE will randomly pick between DRC or no DRC.

Making an option to exclude it would be useful, because DRC (dynamic range compression) severely affects how the audio sounds. It is very bad for any kind of music, and drastically reduces the listening experience.

Example: YT audio format "251-drc" is for DRC, and "251" for no DRC.

Aleksoid1978 commented 3 months ago

As far as I could understand, YouTube does not provide any information regarding the DRC. How then can you distinguish ?

Comitant commented 3 months ago

Right clicking on a video and opening "stats for nerds" will show that you're being given DRC audio. In extreme cases it will show somewhere around 30db normalization.

You can only compare the difference by downloading the formats externally through yt-dlp.

Aleksoid1978 commented 3 months ago

There is no way to know that a particular audio stream is DRC. Well, it wouldn’t be bad to provide at least a couple of links from YouTube with DRC.

У меня нет никакого DRC на этом ролике, видимо еще и от региона зависит )

Comitant commented 3 months ago

It's extremely rare for the player to pick the DRC track but I still decided to give it a mention. It seems to be more common with non-music videos, though. With that being said, I couldn't actually replicate what had happened before to give a solid example.

The normalization is particularly aggressive on content like quiet songs, ambience and asmr, such as these: https://www.youtube.com/watch?v=_8ZcmsgK2Y4 & https://www.youtube.com/watch?v=gcnLYrxLlhU

How do you determine that a track with DRC is being used? I understand that you are using the yt-dlp parser?

Aleksoid1978 commented 3 months ago

Done - ignoring DRC audio for yt-dlp.

I can tell depending on if it is unusually loud at my normal listening volume, it also typically has amplified background static. I verify it by downloading both tracks with yt-dlp.

Awesome, thanks!
