Realtime Audio Lab (Version 1.0)

This program is designed to analyze the performance of speakers realtime, by making a sweep. It also has a number of other cute features. You can see some examples here:
  • EJ Corvette Speakers
  • Utah Speakers
  • 1989 Ford Ranger with Boss radio

    This program can generate sweeps automatically by pressing the Sweep button on the right-hand side of the screen. You can control the volume of the output sinewave by moving your mouse over the area above it where it says "SIN". You can see VU, DB and Percentage info for overall amplitude. You can change the peak mode by clicking on the peak mode button. There also is a spectroscope available in the middle of the screen. You can alter its appearance to make it appear more visually attractive by pressing on Appear Alter. You can change the graph mode as well as view the current FFT, sliding FFT and a current oscilloscope.
