RedCrab SonoG

Audio tone generators can be very helpful for testing specialized equipment, and you can even have a bit of fun listening to sound at various frequencies across the human hearing range.

RedCrab SonoG is a relatively simple application that provides you with two tone generators, which can be used simultaneously. It can also generate DTMF signals, and it is not difficult to use.

The application allows you to use two identical tone generators, which are displayed in the main window side by side. You can use the number pads to enter values, and the sound frequency can be fine-tuned using the dials.

RedCrab SonoG can generate audio tones between the 1Hz – 20 kHz range. The lower limit is well below the human threshold of hearing (around 20 Hz), but most people should be able to hear sounds with frequencies close to 20 kHz.

In addition to generating simple tones, the application allows you to choose between multiple types of waveforms, such as sinusoidal and rectangular. It also supports, tone-burst, modulation, sweep and DTMF pulses.

If you aren't entirely sure how the program should be used, you can check out the online user manual, which provides helpful explanations.

You can select the right frequency either by moving the dials or entering the values directly, which can be done with the help of the two keypads or using your keyboard.

Overall, RedCrab SonoG is a lightweight application that can be both useful and fun. It is designed to generate audio tones at various frequencies, enabling you to test both your hearing and sound equipment. What's more, it comes with an extensive user manual that can help you get started.
