Is there any software that shows the frequency of audio input as digital display?Tuner softwares can not read frequencies above 1 khz regularly.The following link is an example of a tuner screenshot. http://www.techmind.org/audio/mustun.gif
I am looking for a relation between electromagnet (or permanent magnet) and frequency.For example what is the frequency of an electromagnet that has 45000 gauss electromagnetic field?
Thanks.
