Unity download audio

I have a project where I need to download and store audio file from a website. I have tried it using .mp3, but as it turned out, it doesn’t work on webplayer (the project is developed for android and webplayer).
I have found a similar post here, which adived to use .ogg, but it didn’t work either. Ogg streaming was not supported (I have tried it on the android version). The only format I could use on both versions was the .wav, but it is extremely big, around 10 times bigger than .ogg.
Do you have any suggestions what I could do?

You could have a .mp3 and an .ogg (which should be supported by the web player) and then use




and put the url for the .mp3 in android and the .ogg in webplayer
