Josh Westberry (ID: 000000d52e5a0841) Voted 4 ★ - Updated 02/28/2024 I couldn't tell if it was working at first, but I watched several videos back to back with different volume levels and I could tell it did something. Where I noticed the most change was on quiet videos when an add would start playing that normally blasted my ears out, it bumped the level down significantly. I noticed when the video started back, it would take a second or two for it to catch up and normalize. Overall I am happy with how it works....beats getting blasted out by adds.

Jorge Díaz (ID: 000000e0eaa02127) Voted 1 ★ - Updated 01/31/2024 Funciona bastante bien, lo instalé para normalizar el audio de mis listas de reproducción (algunos vídeos están demasiado alto y otros demasiado bajo) y lo hace sin problemas y sin que tenga que estar interviniendo el volumen cada vez. Cumple perfectamente lo que promete en ese sentido 👍 Edit: Funcionaba perfecto, pero con la nueva política de adblockers de youtube, ya no se pueden ver los vídeos, por lo que tuve que eliminarlo. Por mi parte solo me interesa la normalización del volumen, así que si pueden dejar opcional el bloqueo, seguiría utilizándolo.

Павел «Dark Paul» Бугров (ID: 000000703f60fba4) Voted 3 ★ - Updated 10/31/2023 Нормализация работает нормально, полезно для тихих видео, НО ломает отображение чата, например если смотреть запись стрима. и добавляет неактивную кнопку для скачивания видео. Если это поправить, будет хороший плагин

Radio Silence (ID: 000000c9e4739107) Voted 5 ★ - Updated 10/06/2023 Normalizer is a bit glitchy. you might wanna turn it on and off a few times. My usecase is the opposite from the most folks here. I use it to make the sound louder. You know how sometimes you listen to a great song and want to have it louder, and despite you maxing the volume setting on YT, it's still only half or even quarter of the max sound level even according to Windows audio settings. This extension fixes that. Great job!
