Quicktime 7 features and compatibility

I particularly admire and use Quicktime 7's ability to adjust pitch and tempo when playing back audio files (I'm a singer). But I can only do this on my badly outdated MacBook Pro. I want to enable this ability on my M1 MacBook Air running Ventura and QT Player 10.5. But the more modern QT version lacks these to-me-essential features. Might I install and use my old QT7 on my MacBook Air? If not, is there another simple way to regain these abilities
