Thing 14: Spectrogram Player v2

Yesterday, I tried to make a spectrogram-player that plays a spectrogram. See thing 13 It was pretty bad. Today I tried a second approach I learned of after making the thing yesterday. This time I use white noise and bandpass filters. I think it's much better than yesterday's. Feel free to compare using the same images in both.

Thing 13: Spectrogram Player

I tried to make a spectrogram-player that plays a spectrogram. It's pretty bad. Below are two hand-drawn spectrograms you can download and upload to try it on. You can also upload any image, but if the image doesn't look like this, then your ears may bleed even more.

The way it does this is it makes a pure sine wave for each row in the image and alters the volume according to the brightness throughout. I learned after making this there are better ways of doing this such as using a noise source with band pass filters. Oh well. Also, no idea how well this would work on an actual spectrogram. Will just have to wait until I make a spectrogram-maker I guess.
