Tone Generator
By NCH Swift Sound Software
NCH Sound Tone Generator lets you create audio tones, sweeps or noise waveforms using a Windows computer with a sound card or a PocketPC handheld. Typical Applications include test tone generation in studios for the alignment of levels, calibration and testing of audio equipment or speakers, tuning music instruments as an accurate reference tone, demonstration of audio principles to students and more. Features ~ Sine wave, square wave, triangular waveform, saw tooth waveform, impulse, white noise and pink noise. ~ Supports frequencies from 1Hz to 22kHz bandwidth (subject to sound card). ~ Multiple simultaneous tones (1 to 16 tones can be created at the same time) (useful to create harmonics). ~ Mono or separate stereo operation (ideal to create dual tones or ''beats''). ~ Tone Sweeps (Log or Linear). ~ Plays tone or saves as wav file.
Soundmasker
By Vectormedia Software
Sound Masker generates various types of noise and is a complete replacement for hardware noise masking products. You can mix and match combinations and playback the output in realtime, or alternatively you can record the output straight to a wav or mp3 file, ready to create your own custom white noise masking CDs or MP3s to listen to anywhere. You can save as many of your configurations as you wish, so you may save one to help you sleep at night and another to mask noise throughout the day. Sound Masker is completely customizable and is ideal for home or office sound masking. Soundmasker is extremely easy to setup and use - no previous experience is required, yet is powerful enough to rival professional hardware noise masking solutions costing hundreds of dollars.

White Noise Player
By Sardine Software
If you have ever been in a situation while using your computer where the background noise in the room makes it impossible to work then White Noise Player is a very useful too. White Noise Player will play any .wav file on your computer you choose on a continuous loop cycle from your system tray. This allows you to choose any sound you like from simple white nose to a relaxing rainfall and at the same time, reduce the noise you hear that may distract you from your work.
Really Random Numbers
By Sunny Beach Technology, Inc.
Really Random Numbers provides an alternative to pseudo-random number generators. Really Random Numbers uses a real-time number generation process based on white noise in energy from the PC''s sound card. The result is random data that passes virtually all statistical tests of randomness and improves significantly over biased and predictable pseudo-random number generators. The software operates efficiently in the background with low memory and CPU usage. Random data is buffered for delivery in memory for delivery to other applications via an API and can also be written to file. Using either the data files or its simple programming interace, Really Random Numbers allows you to quickly retrieve high quality random data for use in your own applications. Sample applications and code are included for Visual Basic / VBA, Visual C++, and Microsoft Excel. The software is compatible with all versions of Windows 95 through Windows XP. A sound card and possibly a microphone are required.
Virtins Pocket Instrument
By Virtins Technology
Virtins Pocket Instrument is a powerful Pocket PC based virtual instrument software. It consists of a real time oscilloscope, a real time spectrum analyzer and a signal generator, and can run them simultaneously. Unlike most of the sound card oscilloscopes in the market which search trigger event after data collection, it features a specially designed data acquisition approach which is able to monitor the input signal continuously without missing any trigger event before the frame of data is collected. As a result, Virtins Pocket Instrument boasts a very fast screen refresh rate and thus a truly real time response. It supports sophisticated triggering method including pre-trigger and post-trigger which are generally missing from other sound card based instruments. Virtins Pocket Instrument features zooming and scrolling function and allocates most of the screen for data display, all of which are essential for you to exploring the fine details of the measurement data. In contrast, most of other sound card based instrument spent much precious screen space to simply mimic the panel of the conventional instrument. Virtins Pocket Instrument provides a comprehensive range of functions including wave form addition, wave form subtraction, Lissajous Pattern display, transient signal recording, RMS amplitude spectrum display, Relative amplitude spectrum display, phase spectrum display, auto correlation coefficient display, cross correlation coefficient display, function generation, arbitrary waveform generation, white noise and pink noise generation and sweep signal generation, etc. Virtins Pocket instrument stores data in either standard WAV file or TXT file. It supports WAV file importing and BMP file exporting and printing. Visit www.virtins.com for further details.
