issues with ears

[ghost]

i did the following:

• downloaded EARS
• installed python in ubuntu
• downloaded the requirements
• downloaded and installed anaconda x86_64
• added my audio driver
• started the server

i noticed the following:

• whenever I start the audio engine the bokeh server goes down

here's my console log:

New librosa versions have changed the API, so I will have to update it accordingly. For the time being you can rename the ref_power parameter to ref for newer versions or stick with the older version. As there were some other issues reported with more recent librosa, I've pinned it to 0.4.2 until I have enough time to revamp the whole EARS project.
