14 Best Free White Noise Generator Software For Windows

Here is a list of Best Free White Noise Generator Software For Windows. These freeware use your PC’s sound card to produce White noise or other types of audio signals. While generating White noise, you can customize the sample frequency (Hz), sound level (dB), channels, volume, duration, etc.

In all of these White Noise generator software, you can play sound of White noise which is generally used to relax, sleep, or concentrate. In a few of these, you get flexibility to schedule events for playing White noise sound. Some of these freeware let you generate White noise signal to visualize it for real time analysis a.k.a. Real-Time Analyzer (RTA). You can visualize the White noise signal as Spectrum, Waveform, Oscilloscope, etc., for real time analysis. You can view the signal graph with statistics like data rates, actual frame rate, range, etc. In many of these, you will get both of the above options.

Apart from White Noise, you can generate other types of signals including sine wave, square wave, linear sweep, log sweep, etc. Also, you can play pink, blue, gray, brown, and violet noise sound in some of them.

To hear or analyze White noise sound, many of these let you import sound files in WAV, MP3, WNA, WMA, etc. formats. You can even record White noise sound and export it in WAV, MP3, etc. formats.
