hey everybody! i'm new to this

trying to read an audio file from a simple path and i'm getting an error: 

audio_data = 'C:\\Python\\Music\\Hiroshi Suzuki-Romance.mp3'
x , sr = librosa.load(audio_data)

the error reads:

It looks like you don't have any decoders installed which can handle mp3.

You'll need to install gstreamer or ffmpeg to work with audioread. I generally recommend using the conda packages for this, though it looks like you're not in a conda environment.
