I’m the developer of Transitions DJ ( https://dj.app/ ). If anyone can connect me with the team at Apple Music, I would be interested in doing an integration.

Music is separated into stems using a version of Demucs modified to support streaming. Pitched stems are then processed by a machine learning model trained to detect the fundamenta…

Wavacity developer here. I released this a year ago under the name "wavvy" but needed to rename the project because of a trademark conflict. https://news.ycombinator.com/item?id=32…

On the M1 Mac I actually measured lower CPU usage during audio playback on WASM compared to the native desktop version which uses Rosetta. I'm not sure if the slowness is due to Ro…

It's probably the most visible project using the wxWidgets framework and in the audio domain which fits well with my experience building the DJ app.

It is rendering using the 2D canvas API. There's a device context class (wxDC) for each wxWidgets port that implements primitive drawing ops (DrawLine, DrawText, etc). For the WASM…

I originally developed a WASM port of wxWidgets for https://dj.app/ . When it came time to open source wxWidgets-wasm, I decided to port another complex app as a test case, and Aud…

For a simple and straightforward FFT implementation, I would recommend taking a look at the Kiss FFT source code. http://sourceforge.net/projects/kissfft/

Regardless of whether the building looks dumpy, the view of Midtown is magnificent: http://picasaweb.google.com/lh/photo/iU0pdqJt5xOtzMhGIbrfbg?...

And another: Algorithm to predict football scores.

I believe they are using a non-standard crossover operator in this implementation. A standard crossover operator will generate some permutation of the genes of the two parents: eit…

I would target people who are not completely satisfied with the competitor's product. If I see people tweeting competitors asking for feature X, where my product already has X, I w…

I haven’t tried a Bloom filter, but I think for my application, the simple bit array might give better performance. The nice thing about the bit array is it works great on the wors…

I recently used this algorithm for speeding up an iTunes style search function. Originally I did a strstr over every item in the database, but it wasn't quite fast enough. I precom…
