Help me with some Audio filters

It's a toss-up between putting this in Help Desk or here. But since this forum is dedicated towards all things audio, I thought I'd try here.

I'm basically trying to improve a keyboard recording, and I want it to sound less 'electronic' and more like a piano. The ideal situation is to grab hold of the MIDI files and apply suitable soundfonts, but it seems the raw source is WAV.

So, here is my question.

What is the best combination of filters I can use (in Audacity) to improve this kind of file? My goal is to make it sound more like a piano than an electronic keyboard.

Thanks in advance!

Jam it back in, in the dark.

Well, can't say I'm not disappointed that it's nigh near impossible. But I appreciate your feedback.

Assuming I ditch Audacity and declare that the sky's the limit, what's the best way I can modify this recording?

There's nowhere I can't reach.

So it all goes back to MIDI. Oh well.

I'm not too keen on having audio-to-MIDI conversion, packrat, since my sibling is the performer. So, why bother converting when all we need is an appropriate electronic keyboard that outputs to MIDI instead of WAV

Thanks for your inputs, anyhow. I'll try a low-pass filter to remove the high electronic frequencies and hope the resulting muddy sound will pass for a piano =O

How ya doing, buddy?
