This project demonstrates how you can synthesize complex sounds using multiple sine wave tones. This project manipulates the tones in Scratch, which has its limitations. I also made a version using BeepBox, which is much closer to the original sound: https://scratch.mit.edu/projects/779705874/ ☛ Click the green flag to listen to a synthesized version of the Scratch Cat Meow, produced by manipulating the pitch and volume of four sine wave tones. The upper spectrogram shows the original meow sample. ☛ Click it to listen to the sound. The lower spectrogram shows a recording of the synthetic meow produced by this project. ☛ Click it to listen to the recorded sample I used to make the spectrogram. ☛ Click the buttons to the left to mute specific tones, and then click the green flag to listen to the result. ☛ Click the buttons to the right to play each tone with the original pitch and volume.
