Yeah especially compatibility with Apple browsers was very important for them. I'd added functionality to normalize audio for verification but they removed it multiple times because it didn't work on Safari for various reasons. I ended up building an extension for Firefox that normalizes the audio on the website if installed: https://github.com/est31/vmo-audio-normalizer https://github.com/est31/vmo-audio-normalizer https://addons.mozilla.org/de/firefox/addon/vmo-audio-normalizer/ https://addons.mozilla.org/de/firefox/addon/vmo-audio-normal... In general I don't think normalization should happen at the backend. It's useful for training data to have multiple loudness levels, so that the network can understand them all.
