(This is a DOS program and is not supported any longer) Now you can view the audio signals with this audio spectrum analyzer. Audio Analyzer will display the change in frequency in relationship to time, so you can "SEE" what SLOW SCAN TV, RTTY, PACKET, WEATHER FAX, and other tone based audio signals 'look like'. The waveforms can be view in a REAL TIME snapshot mode, or recorded to VOC (voice) file for viewing over and over. A TIME MEASUREMENT feature has been added to be able to measure sync pulses, etc. in milliseconds. You can download your copy HERE today for FREE, but NO SUPPORT!
