I built this as a christmas fun project, so feel free to ask if you'd like me to explain something.

Have you got an example file - ogg/mp3 to listen ?
- fxtentacle 12y ago
  No, because I'm afraid that providing one would cause me quite some legal problems. Over here (in Germany), a lot of movies / sounds get blocked by GEMA or you have to pay horrendous fees to be allowed to use them. But for development, I used this 5.1 YouTube video for testing the surround simulation: http://youtu.be/juIJGBxj-4w http://youtu.be/juIJGBxj-4w And for testing the music enhancer module, I used Far Too Loud, Circle of Alchemists and OVERWERK. So these should sound pretty cool with my app: https://soundcloud.com/overwerk/conquer?in=overwerk/sets/conquer https://soundcloud.com/overwerk/conquer?in=overwerk/sets/con... https://soundcloud.com/far-too-loud/far-too-loud-doomsday-machine https://soundcloud.com/far-too-loud/far-too-loud-doomsday-ma...

    Use some creative commons songs.

      Great idea, thanks :) I used my favorite CC song, which is Pocketpod - Hybrid: Original: http://www.hajoheadphone.com/assets/417586_hybrid_orig.mp3 http://www.hajoheadphone.com/assets/417586_hybrid_orig.mp3 Virtualization: http://www.hajoheadphone.com/assets/417586_hybrid_hahe.mp3 http://www.hajoheadphone.com/assets/417586_hybrid_hahe.mp3

        Thanks for letting the non OS-X'ers in! :)

        There's lots of distortion (like digital clipping but low-passed, if that makes sense) at the louder parts of the song. It also seems that the processed sample has its dynamic range reduced by a lot.

    It seems like there's a possibility you could work with one of these artists in some kind of promotion deal. You could have limited distribution of their track as a test app, and they could get a little promotion along with your cool space-age idea. I bet a nice email to their PR people would be worth it.

      I am not from Germany, but I seem to remember reading that the GEMA licensing is mandatory even for bands that give their music away for free. Can anyone clarify if that's the case?

    For my own project (much simpler—only deals with stereo audio), I used this: https://www.dropbox.com/s/t5dvah8zke3uky8/HellOfAGuy_demo.mp3 https://www.dropbox.com/s/t5dvah8zke3uky8/HellOfAGuy_demo.mp... Audio came from here, with a very open license: http://www.audiogroup.web.fh-koeln.de/anechoic.html http://www.audiogroup.web.fh-koeln.de/anechoic.html.

Did you look at creating a user-space audio driver instead of the kernel one? 10.9+ only, but if you built this recently it probably makes a lot more sense. https://developer.apple.com/library/mac/samplecode/AudioDriverExamples/Introduction/Intro.html https://developer.apple.com/library/mac/samplecode/AudioDriv...

  Thanks for the link. I went with a kernel driver because I knew that approach would work on old OSX (starting with 10.5), but since i'm delivering two kexts anyway, switching to an user-space driver for 10.9+ would probably reduce CPU usage :)
