There is better software, although it might not meet OP's goal. There's e.g. Melodyine, which can identify (and change) notes from individual instruments in polyphonic passages, and there are also tools to estimate and remove reverb and other forms of processing. Those are based on classical DSP. OP just wanted to use "AI".
