hw9 - issue with convertToWave function

[t-a-trahan]

Hi friends,

I'm having an issue with the convertToWave function defined early on in the hw9 notebook.

When I try to run it on the audio sample given at the top of the notebook, I get a 'file not found error.'

I definitely have defined the correct path for the sample file.

Thanks in advance for all help!
