I just learned how to convert an audioclip from a 33.3 rpm vinyl record to 78 rpm, here: https://community.adobe.com/t5/audition/converting-33-recording-to-78-how/td-p/9448709?page=1 What I need is similar but probably harder. I am developing a web application based on a segment from a 2013 TV program. Only the first seconds are relevant: https://www.youtube.com/watch?v=8MF04X2aLBw T...

Forgive the ramble but I don't have to problem pinned down completely: I'm curious about the mathematical relationship between the harmonic series= and equal temperament. I'd like to write a program that quantizes glissa= ndos into the harmonic series similar to birdsong but, of course, by defini= tion, you can't transition between equal tempered intervals with the harmon= ic series. =20...

I ran across a problem in a DSP book that got me to thinking (the best kind= of problem). The author suggests that we can illustrate aliasing by sampl= ing an audio signal at a high frequency and then replacing samples with zer= oes to get a lower effective sampling frequency. For example, if we sample= at fs1 =3D 32 kHz and then keep every M =3D 4th sample (replacing the othe= r samples ...

I hope everyone is well. This one is long and possibly boring. Since now we are apparently all epidimologists I thought I'd give it a try along with everyone else. And I have three technical questions in the below. USA total, and USA by state statistics are available at the COVID Tracking Project among other places. I've seen a lot of actors draw conclusions from such data using pure...

I've been pleased with ease of use of the scipy.signal package for implementing bandpass filters: the `signal.butterworth()`, `signal.sosfilt_zi()` and `signal.sosfilt()` functions do just what I expect for a filter with constant center frequency and bandwidth. But now I'd like to make the frequency and bandwidth settings be time varying functions themselves, and I'm not sure how to
