Ideally, I would like to make something else based on this algorithm that would allow me to leave my work first. Like maybe some fancy 2D/3D visualisations. I want to then open-source the core algorithm. Maybe I should do it sooner though. I don't know, any advice?

I will download your app later.

It’s interesting as I just worked on FFT and sound visualization with Python, Seems quite troublesome to circumvent the need for a sample buffer or time-windows.

If you see a way to monetize I would definitely do so. Only you can decide how unique your method is. If it is very unique, patent it? Perhaps Shazam or other apps could use your method?

It is really hard with FFT to get a good frequency representation. I've described a bit more on the app website why on front page. It's basically like deciding whether you want to detect the frequencies well, and loose time resolution, or if you want better time resolution, loose the ability to detect low frequencies :) What I've done is kind of like wavelet transform, but "real-time", and I have one extra feature for "high-resolution" frequency detection that goes in addition, and I've done the math for that myself, I haven't seen it anywhere... Wouldn't have time to do the patent at all, I have another main job :) Ideally, I would rather make something more impressive with it, and then "sell out" :)

Multi-Resolution FFT and Short-Time FFT (STFT) is commonly used to avoid the frequency/time resolution tradeoff. Example here https://ccrma.stanford.edu/~jos/sasp/Multiresolution_STFT.ht...

That looks good!

I would love to use your algorithm for a personal hobby project. So far I’ve ported other similar algorithms such as Colorchord but this seems like an interesting take on getting data out.

Being able write a lib to plug into TouchDesigner or OF would make it fun to write other kinds of visualisations.

I am definite considering releasing the algorithm, it's currently in C++. But I want to build something on top of it first, so that its application can attract more attention. I've tried releasing the "algorithms" before -- nobody cares if you first don't show something cool can be made with it...

I'm open to help write bindings or cool demos if you're interested.

thank you! I can clearly see the interest among people now! I will think what's the best strategy. Definitely be releasing the core algo open source, need to prepare, figure out what's the best way to do it. Thanks again!
