Hello there,
So, I know that mp3 is slower (cuz it needs decoding) to play in Unity as the article below says.
[http://docs.unity3d.com/Manual/AudioFiles.html](http://docs.unity3d.com/Manual/AudioFiles.html)
Is this still true when I use Fmod to play sounds? Would it still take more processing power to play mp3 in Fmod versus wav?
Thanks!

Yes. See [http://52.88.2.202/documentation/#content/generated/platform\_windows/performance\_reference.html](http://52.88.2.202/documentation/#content/generated/platform_windows/performance_reference.html) for comparison of PCM (wav) vs Vorbis (compressed format similar to MP3).

Vorbis in the case means our own encoder/decoder. Use the fsbank or studio to compress the files.
