I made a new CLI visualizer

I've recently made a CLI visualizer.

Spectrum in stereo mode

Spectrum in mono mode

Ellipse visualizer

Lorenz visualizer

This project was heavily inspired by https://github.com/karlstav/cava, http://rybczak.net/ncmpcpp/, and https://github.com/sickill/rainbow

If you want to install it, I've already made an AUR package.

yaourt -S cli-visualizer

The github link is https://github.com/dpayne/cli-visualizer

I don't know what this does or why... but I want it :-)

It's a cli visualizer. Currently it only support MPD.

Re: I made a new CLI visualizer

Looks great! If Cmus support is on the horizon I will definitely try it.

Re: I made a new CLI visualizer

Pulse support would be awesome! Anyway, lovely work, will give this a spin.

Re: I made a new CLI visualizer

I've been working on some experimental support for alsa and pulseaudio. In the alsa config created a default sink with a fifo file as output. Something like this

pcm.!default {
   type file               # File PCM
   slave.pcm "hw:0,0"      # This should match the playback device at /proc/asound/devices
   file "|safe_fifo /tmp/audio"
   format raw              # File format ("raw" or "wav")
   perm 0666               # Output file permission (octal, def. 0600)
}

It does not work directly with pulse audio, but it does work if alsa is installed with pulseaudio and alsa is then piped to pulseaudio. The full asound.conf examples are under https://github.com/dpayne/cli-visualize … r/examples The result is a fifo file exactly like mpd's fifo file which is nice since I'd prefer not to deal with alsa or pulse audios apis. The main issue is that it requires a helper program "safe_fifo" and as a result has proven to be very fragile. If anyone knows a better way let me know.

Re: I made a new CLI visualizer

I finally got the visualizer working with pulseaudio correctly on my computer. Much of the code was taken from the way CAVA uses pulseaudio, their way ended up being much simpler than the way I was trying. The instructions to enable it are here https://github.com/dpayne/cli-visualize … setup-easy

Re: I made a new CLI visualizer

Could you paste the output of `g++ -v` as well as the entire build output? It does appear to be building on my box but I think it's likely that something broke with the latest version of gcc.

Re: I made a new CLI visualizer

Ok, should be fixed now. The newer compiler, g++ 6, broke the build.
