At the top right, there's a globe icon, and you can choose English from the drop-down. Then, the search filters on the sidebar will all be in English. When you display search results, there's an option to include the waveforms. If you look at the waveform of the reference track, you'll see it's pretty percussive and quiet, so when you look at waveforms that have less variability, those can just be discarded visually without you having to even listen to it.
