SweepGen - Sine Wave Sweep Generator
This program uses your windows sound card to generate a swept sine wave using parameters you input. Includes ability to pause and step frequency up / down. Also, the program simultaneously records using the sound card, plotting an amplitude versus frequency graph. I wrote this for people who want to test the audio response of hand-made musical instruments. The instrument's plate is excited using the swept sinewave output through a transducer, and a microphone is used to record the resulting amplitude of the plate's response. Now includes ability to save data to file.
NOTE: To perform both the sweep and analysis functions simultaneously requires a sound card capable of Full Duplex operation. If your card does not work, try getting updated drivers. SweepGen is a 32-bit program for Windows 95 or Windows NT.
