Making sure file has audio before trying to read from the audio buffer.
Removed smoothing function cause that just makes no sense over here.
Added a method to check if the audio is fully loaded.
Switched back to using floats. But this time our asset reader makes sure to give us LPCM 2-channel 32-bit interleaved little-endian floats, no matter what the input audio is.
Added multi-channel support.
Fixed a bunch of silly bugs.
Added a fun example showing how to access all the audio data.
