If anyone is interested, I cloned the project over to Github, and modified it to read ~1MB of data from /dev/random and loop over that. It cut down on the cpu utilization significantly (from 5-6% on my macbook pro to 0.5-0.7%) You can get it from the download section of my project page, here: http://github.com/justfalter/noisy or you can download it directly here: http://cloud.github.com/downloads/justfalter/noisy/Noisy.app.zip

If you try to download Noisy from this page, it tells you that you are downloading Noisy, but in fact it tries to install some other software, not Noisy, which contains unknown content. Several sources have reported that "MacUpdate Desktop", the program it tries to trick you into installing, contains malware. Don't believe me, Google it yourself.

After some quick analysis, there seems to be a 3dB/Oct attenuation below 400Hz on the pink source?? Not sure what's causing this but it appears not to generate try pink noise.

Thanks for the update! What makes Noisy.app use 10% of my CPU while Noise.app (which still works for me under Leopard; 1.5GHz PowerBook G4) uses 1%?

Thanks for bringing this to my attention! I changed the random number generator from a simple mathematical formula to using the Unix /dev/random file. Although /dev/random produces more random data, it is also more computational intensive. I can't really hear a difference between the simple formula and /dev/random, so I will change it back in the next release :) It is also possible that the new CoreAudio APIs in Leopard are using more CPU. Let me check on that as well.

Just thought I'd check in to see if there is going to be another release sometime soon. Thanks!

Trying to get the original Noise.app to work once I upgraded to 10.5 was VERY frustrating. Thank you for this much needed update!

Version 1.2

Is it *absolutely necessary* for a white noise generator to be 10.5 only?? I find it pretty hard to believe that this is using any features of the OS not found in earlier versions.

Noisy is based on Noise's source base. Both use CoreAudio to generate the white/pink noise. However, the APIs used by Noise were deprecated in Leopard and replaced with new functions. Noisy could continue to use these old functions, but doing so might unexpectedly break Noisy in the future. If you want a noise generator for Tiger, check out Noise. I believe that somebody posted a link to a Universal version.
