Ooof, I’ve been busy. Family was in town, finals are looming, and I had to finish up my PhD proposal. I have two new music related posts to get up.
The first is my audio effect. I had to implement an audio effect from scratch. I decided to try making something that sounds like the batman voice, from Batman Begins and The Dark Knight. I ended up implementing a real time version of an effect called a Whisperizer. This was fairly non-trivial, as it required a Fourier Transform to create, and the FT mathematically requires a lot of time samples, which makes real time very difficult. I got it to work using a short time fourier transform (STFT) with some windowing and overlapping, and it sounds pretty decent.
I originally wanted to run it on a sample of Adam West, saying that line about on coming thrust of manhood from the campy 60s show, but I couldn’t find a sound clip. So here is me saying it:
And here is that same sample after I ran my effect over it. This actually works in real time, although it’s hard to show that with a browser post.
My next post, which is probably not gonna be today, is going to demonstrate the synthesizer i made.
