Get .mp3 files from PCL on each platform

Hi

I have a PCL with a subfolder Data/Sounds where i have 360 soundclips

I will play the sound on each platform (Android, IOS and Windows Phone) using DependencyServices.Get<>....
But how can i get the soundclips from my PCL, i've made it earlier in Windows universal apps like this.

`
StorageFile file = await StorageFile.GetFileFromApplicationUriAsync(new Uri(@"ms-appx:///Data/Sounds/" + f));
using (IRandomAccessStream stream = await file.OpenReadAsync())
{
...

`
Thanks
