Title: My VJ apps [pc][audio][vj]
Post by: kotu on April 13, 2017, 02:52:52 am
Ok so haven't really shown my VJ apps on here before, although they have always been on my website. There are two ;)

The first tries to generate live visuals in response to the music. It only works with certain types of music :( , but is not too bad. Here is the page ------ > 
http://futurerave.uk/imager.php (http://futurerave.uk/imager.php)
It is currently a free download (and although it just says 'supports windows 10', supports backwards to XP as well)
here is a pic of it working.... you might need to play with your soundcard mixer settings (the record settings - even though this program doesn't actually record audio, but it does capture it)

*EDIT*
Forgot to add my second VJ program - this one is just for displaying text on the screen - but it could be pretty useful for a VJ, or a promoter, or a DJ! It was made in response to a 'how do I do this' thread on a music/dj forum. Again, a free download....... page here ----------->>>>

Interesting. You should add in the topic title  that it's for audio, for more exposure. I didn't notice this until now. I'll check it out this weekend or monday.

8) Well @Juju , I will help as much as I can. Did you get the .exe to run? I can't remember (you had errors?). There is a new build up there now so try downloading that.

If the exe runs but no nice graphics... then..... look at the following.

- press the plus symbol - this will give you debug graphs, however, these may be blank, such as the following.....

(https://s15.postimg.org/tqa9dnv63/image.png)

(You should have music playing on your PC) - the black top two sections show the program has no audio being captured, that it can work with. This normally means you have to change your sound card settings, to capture from say 'Stereo Mix' instead of 'Line In'

Then you should get the full experience :D  ......... which looks like this in the debug window - those little curve shapes are kick drums. Yay!! Good luck juju :)

that audio visualisation tool is really interesting ^.^
are u only scanning for changes in volume? or for changes in frequencies, repeating patterns like the beat, or maybe even changes in these repeating patterns? ^^
nice work  :thumbsup:

Thanks

I perform an FFT to split the music into 512 frequency bins, and analyse the bottom 8 of those to detect kick drums. As my website says, the program works best with hardcore music, and only looks for 4/4 kick drum patterns.

Yeah, it works now in XP, but nothing shows up in debug mode.

Like I said, you probably need to change your soundcard settings.
Title: Re: My VJ apps
Post by: Juju on May 08, 2017, 10:46:43 pm
Yeah, the stereo mix did not work.

Well, it might be a problem with DirectSound audio capture not working correctly because it is on a virtual machine.

Can you record the audio that is currently playing (ie. in Audacity or Soundforge) ? That would be key information
Title: Re: My VJ apps
Post by: Juju on May 08, 2017, 11:07:42 pm
Yeah, tried Audacity, not working.

Hmm

Looks like you need to install Windows 10 over your Linux partition  :P

Virtual sound card worked.

Something I discovered the other day - having 2 open at once is better than just having once

*edit*
something like this

and for bonus points, anyone that can correctly name/guess the [carefully camouflaged, GIMP] dj effects unit in the background, will receive one bonus karma point from me, also, if anyone does this within 3 minutes, i will risk TAKING MY OWN LIFE by minus-repping @DJ Omnimaga , for no reason, less than once

thanks bye

In the thing that says 215.3 BPM, is it possible to change that setting to a different BPM or to beatmatch the current playing song?

I am not sure wat u mean  - is it stayed on 215.3 for long ??
that is very unlikely unless you are playing a minimal track  with a bpm of 80.749 _, 161.499, or 322.998

is this a trick

The BPM never changed during the entire time I played any audio. It remained stuck at 215.3 BPM, even before I started playing a song.

I just tried this again and it worked. For some reasons, my playback device was set to Microphone even though in Audacity it was set to Stereo Mix.

you ran the program then

Post by: DJ Omnimaga on May 10, 2017, 03:41:52 am
Of course I did, both times, and I even tried  multiple times.

I suspect that the culprit was the recent Windows 10 update, because it resetted many of my audio settings, like it does on every single Windows 10 update
