[amsat-bb] Spoutnik41: FFT under Windows

["Peter Guelzow" <pg@xxxxxxxxxxxxxx>]

Hi All,

For those who want to make accurate Temp measurements on 
Sputnik41/RS18, the "Spectrogram Program" running under WIN95/98 might 
be a perfect choice and it's *free*..

We used this program during the Thermal-Vac test of AMSAT P3D
to measure the maximum speed of the Wheels with some sort of
microphone mechanically coupled to the spacecraft frame...
It was realy fun!!!

Spectrogram version 4.2.7 is a freeware dual channel audio
spectrum analyzer for Windows 95/98/NT which can provide either
a scrolling time-frequency display or a spectrum analyzer scope
display in real time for any sound source connected to your
sound card. Spectrogram allows unlimited recording and playback
of the sounds from the audio spectrum display and can provide
very high resolution spectrum analysis of wave files with a wide
choice of frequency bands and frequency resolution and either
linear or logarithmic frequency scales. Spectrum data logging
capability is also provided. Version 4.2.7 replaces all earlier
versions and provides improved audio quality, print-window
capability, spectrum averaging for noise reduction and detection
of weak signals, and more flexible scanning and recording
capabilities. Spectrogram is ideal for any purpose related to
sound spectrum analysis including

   Analysis and identification of biological sounds 	 	 	
   
   Analysis and identification of human speech 	 	 	
   
   Analysis of musical performances 	 	 	
  
   Tuning of musical instruments 	 	 	
   
   Evaluation and calibration of home audio systems 	 	 	
   
   Ham Radio audio reception and tuning 	 	 	
   
   Analysis of radio interference including atmospheric 	 	
   electromagnetic effects

Spectrogram requires Windows 95, at least 16 mbytes of RAM, and
a Windows compatible sound card.
