That's right, no more of that using your microphone stuff. This uses one main sprite (the other is just for visualizing) for the code and you can easily use it yourself. All you need to do is upload your audio, take a screenshot of it and make it a costume. Then run the detect audio custom block with all the information needed and your all set. Use the list to replay your audio by making an index variable and then sort through the list. As easy as that! Check out SmartDetect+ for a more complex version with a more precise end result (recommended for longer audio tracks): https://scratch.mit.edu/projects/955285040/
