Linux based Frequency Generator
We need a simple program that will generate frequencies to run on Linux with x-windows/KDE/Gnome/Xfce., through the computer's sound card.
Generate Sine, Square and Saw Tooth waves
Frequency range from 0.1Hz to 20kHz
Ability to Pulse the signal - for example, generate 2750Hz while pulsing at 20 Hz.
Adjustable Duty Cycle
Frequency sweep - Run from one frequency gradually moving to the second, adjustable in seconds.
Example: Set frequencies 2550hz 2555 Hz 50 seconds. It would generate 2550 and gradually move to 2555Hz over 50 seconds.
Sweep needs to be selectable - Linear or logarithmic
Adjustable duration in seconds
