Cannot load native dll in WebGL build

Hello, I'm trying to use NAudio to get a mp3 (using WWW) into an Audioclip. The thing is NAudio uses Msacm32.dll which I tried adding to the project, but the webgl build still cannot find it. The standalone build works well(it doesnt need this dll tho, because it gets it from the system). DllNotFoundException: Unable to load DLL 'Msacm32.dll': The specified module could not be found.
