Thanks for the comments! How in the world are you able to clean it up? What software?
I'm not sure if it's just me, but a couple parts sounded very odd -- there was a random noise in one portion (1:12) that wasn't in the original.
I have used IZotope RX. I may have misused this tool at some points. Just let me know precisely where so that I can check and possibly improve the correction.
Does 1:12 means 1'12" ? I do not hear anything special here.
Here attached two fully processed files. file_2 is the same like the one in my previous post but with the removal or attenuation of the transient noises completed up to the end.
file_3 has in addition background noise attenuation and a slight equalization.
The recording ends abruptly. Is it for the pedal release noise not being included ? This could also be arranged better.
