NOISE / SOUND MACHINE RECOMMENDATIONS

There are several free software programs that usually outperform
any of even the expensive sound machines (or audio generators).

One of my favorites is:
Aire Freshener 2.0
It's a neat little program that has a bunch of ambient noises/windchimes / white and pink noises. It runs out of the toolbar with a console for picking over 100 sounds (e.g., Day Surf and Thunderstorm, hearbeat), and includes adjustments. It has some nice white and pink noises, and there is even a rock star crowd noise...
It can be downloaded from numerous sites. Use the Link above, or copy the following address into your browser window:

EZAir :Here's a link for EZAir, a neat paced breathing program...
It a multipurpose program that allows selecting sounds that it provides (white noise sounds), or using your own (many can be downloaded in links below), coordinates it to a breathing pattern that you display with a customizable bar graph and pictures, and it interfaces with bioexplorer and other good biofeedback software as well.

There are many other freeware or shareware (small contributions accepted or requested

if you like the software) programs as well.
