the prompt it was given

I run a café and I recorded the background music we play, but the espresso machine was going the whole time and you can hear it over the music. The recording is cafe.wav. Take the coffee machine out and leave the music as it is. Save the result as clean.wav, at the same sample rate and length.

Frozen at v1. This model got this and nothing else.

ground truth

cafe.wav is 18.2 s of the Espresso Rag with a CC0 recording of a Nespresso pump 6 dB under it, and the checker holds the music and the pump apart. The pump is a vibration pump on 50 Hz mains: lines at every multiple of 50 Hz up past 14 kHz, which carry 89% of its energy, and a rush of water that is loudest in the first four seconds.
