Subject: Re: [AUDITORY] Neutral sound for a relaxation experiment From: Bob Masta <audio@xxxxxxxx> Date: Tue, 19 Sep 2017 08:11:37 -0400 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>How about "surf" sound, such as white noise with a slow AM modulation? Easy to generate "live", and can run for as long as you want. More soothing than continuous white, pink, or "colored" noise. If you don't already have a suitable system, the signal Generator in my Daqarta for Windows software can do this with any Windows sound card. Let me know if you are interested, and I can get you started with a Generator setup which you can easily modify to change AM depth or rate, etc. Since it only uses the Generator, it's free! (Keeps working even after the trial period expires.)
