Audio issues on DataFrames tutorials?

I’m delighted to see that JuliaLang is posting some DataFrames materials, and will have a Q&A later today!

However, both this new video and the last set of DataFrames tutorials have some major audio issues. Any chance the people working with Bogumił on this could help figure out audio issues?

Moving this to DataFrames issues…

Also seems like video quality doesn’t allow code to be read. :frowning:

But maybe someone with audio processing experience could remove the echo in the audio at least?

EDIT: Youtube was just slow posting higher quality versions. Video is fine!
