vsergeev / audioprism Goto Github PK

It'd be cool if one could do --fullscreen (maybe with an optional screen-number).
I may implement this but at the moment, I don't have the time :(

Ps: This is a super cool project, thanks for making it!

Around the InterfaceThread, where new pixels are moved onto the texture, something goes way wrong..
Maybe it'd be easier to always draw using the vertical method and then draw the image rotated with SDL if horizontal option is chosen?

I'd like to keep an audioprism window open in the background, to go along with my music player window. I don't listen to music all the time, and I notice that audioprism has significant CPU usage, even when it's just displaying a black screen.

It would be nice if it suspended rendering (and DFT calculations?) when there is more than a user-defined level of seconds of silence or near-silence. I think that'd reduce the idle CPU to acceptable levels.

On ubuntu 16.04:

make fails:

But it works with -lpthread:

I have my monitor set as default but nothing is displaying in the audioprism window.

libpulse 12.0-1
fftw 3.3.8-1
sdl2 2.0.8-8
sdl2_ttf 2.0.14-1
libsndfile 1.0.28-1
graphicsmagick 1.3.30-1
audioprism 1.0.1-1

Is there the ability to focus on particular a frequency range, or set the binwidths of the filterbank elements? e.g., display a spectrogram from, say, 2 Hz-8 kHz with 24 bins. (i picked the bin count and frequencies semi-randomly)

Right now, it seems that these parameters aren't exposed to the user, but I could be missing something.

Would it be possible to add 4K scaling support? Either by a pixel scaling option or some other way? The graph is tiny on my 4K laptop display. I have 200% display scaling enabled but it doesn't seem to affect audioprism, probably because SDL works pixel-by-pixel (at least how I understand it). If you don't have the time/a 4K display for testing, it would equally be welcome if you could at least point me in the right direction to add this feature myself.

Thanks!
