List of the 14 Best Free Signal Generator Software for PC – DinoTechno

In this article, we are going to list some of the best free signal generator applications for Windows operating systems that you can use for making signals or frequencies.

In addition to introducing the best signal generators for the Windows operating system, we also introduced two free online signal generators that can be used on any device regardless of the operating system.

The signal generators, or frequency generators, can be used to make signals using your sound card directly from your local computer without needing to have any other media hardware.

You can use the signals generated using the signal generators for other applications. For example, you can use them for processing by other software that you have installed on your computer. For example, you can use them for signal processing or you can connect and use them with your other electronic devices like earphones, speakers, etc.

As the human ear can hear from low frequencies like 10 Hz to 20 kHz, this software usually generates signals within this range because this kind of signal within this frequency is mostly used for analyzing.

Depending on your needs, you can either go for the simple ones that let you generate signals quickly without needing to go through complex configurations, or use an advanced signal generator that has a lot more configurations and customizations that you can use for making more customised signals.

For example, one of the customizations you can make using an advanced signal generator is setting different frequencies for the left and right channels.

For example, you can make different types of signals; for example, the most popular signal is sinus, but in some of the advanced signal generators you can have some other first two, for example, a square triangle and some other signals that can be used for special purposes or as an input for signal processing in some of their software.

Here we are trying to give you a list of some of the best signal generators for the Windows operating system that can be used on your PC for generating different signal waves that have different frequencies as well.

List of the Best Free Signal Generator Software for Windows

If you need to generate a single-ended signal or a double-channel signal, you can use this Windows signal generator tool.

Using this tool, you can measure the parameters of the audio signal you have, in addition to enabling you to generate new signals.

The double-channel signal is referred to as the signal that has both left-hand side channels but a single-ended signal as either left or right channel. Each of these signals can be made using these signal generator tools according to the requirements you have.

Using this useful signal generator software, you can make signals with different frequencies and amplitudes, and you can also set the waveform of the signal you are going to generate, in addition to some other customizations you can make for generating signals.

The signal generator tool can make different waveforms, such as the popular sinus, triangular, sawtooth, and rectangular signals. You can generate one of these four different waveforms according to your needs.

Some of the the characteristics that can be customized using the signal generator are the frequency of the signal, which can be within the range of 20 Hz to 20K Hz, and the other one is the amplitude of the output signal. If you would like to set a phase angle for the output signal, it’s also possible using this signal generator software.

In addition to generating signals using this software, you can also use it as a spectrum analyzer and a frequency response analyzer tool too.

Tone – Signal Generator Tool

Tone is a free and useful signal generator software for the Windows operating system that allows you to make signals with a frequency of 2 to 20 kHz with different waveforms. For example, you can have sinus, pulses, impulses, linear sweep, logarithmic sweep, white noise, sin bursts, sawtooth waveforms.

You can use this free signal generator software if you need to make simple signals quickly without going through the difficulties of dealing with more advanced programs.

Using this signal generator, you can delay the right channel by any number of milliseconds that you can set within the program’s interface.

SweepGen – Signal Generator Tool

This is another great signal generator software for the Windows operating system that allows you to generate signals with different output characteristics for them.

You can say that the frequency of the output signal is from 20 Hz to 20 KHz, and you can make signals at different frequencies too using this tool. For example, the speech frequency can be made using this tool that has a frequency range of 300 Hz to 3 kHz.

This signal generator only allows you to have 2 different waveforms of signal. The first one is sinusoidal and the other one is a squared signal.

SweepGen transforms a PC into an audio oscillator and signal generating tool for audio testing and education purposes in a simple and effective way. 

SweepGen generates sinius waves that have the properties you’ve specified for them.

In fact, the sound card’s quality is more likely to be the limiting factor than the code in SweepGen.

SweepGen allows you to generate accurate signals and the only limitation you could possibly have is the quality of your sound card, which is the only restricting parameter when you use this program.

The sweet mode feature in this signal generator tool allows you to have both linear and logarithmic ones.

The output level of the signal can be selected in any range between -40 to 0 dB, and the good thing about this tool is that it enables you to use different output levels for left and right channels.

There’s also a growing collection of macro examples and mini-apps. You can use them as-is or make changes to them as needed.

If you need an advanced signal generator tool that allows you to have more than 2 channels, you can use this signal generator, which allows you to have 8 channel signals.

You can specify different output characteristics for the output signal you’re going to make using this tool.

Using this signal generator tool, different characteristics can be applied to both the left and right channels.

The frequency of the signal, the amplitude of the signal, and the signal modulation are some of the customisations you can make using this signal generator software.

If you want to add or subtract an offset from the output generated signal, you can do this using this signal generator tool.

This tool can generate a variety of waveforms, such as sins, squares, ramps, triangles, and pulse signals.

The possibility of adding noise to the output is another property of these tools, which allows you to add pink noise, Gauss or white noise to the output signal.

This software has both free and pro versions, and the possibilities of the pro version are much higher. The pro version allows you to generate signals with any custom properties you want.
