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.

Oscillometer is intended for real-time investigation of data accepted from any ADC you will want. Oscillometer consists of an oscilloscope and FFT spectrum analyzer. Maximum numbers of channels, sampling frequency, bit rate of data, frequencies range, precision are limited only by type of used ADC. The obtained data and images can be saved to files or clipboard. Oscilloscope modes (for dual-channel ADC): original signals, sum, difference, dependence of one channel on another, amplitude distribution of input signals. The synchronization is independent in each of panel. Spectrum analyzer works on algorithm of Fast Fourier transform (FFT). The size of the block a FFT is up to 2^20 (1 M) samples of an input signal. The processing of overlapped in time series of samples of an input signal for combination of high resolution of the analysis on time and on frequency simultaneously. Smoothing windows (weighing an input signal) - more than 50 types. Averaging of results of some FFT: equally weighted - scalar or vector; exponentially weighted - scalar. Number of averaging transforms is from 2 up to 20 or infinite. Synchronization of the spectrum analyzer is independent from oscilloscope. The following parameters can be measured in real time mode: Peak Frequency, Peak Amplitude, Total Power, Signal to Noise Ratio (SNR), Signal to Noise plus Distortion Ratio (SINAD), Spurious-Free Dynamic Range (SFDR), Effective Number Of Bits (ENOB), Total Harmonic Distortion (THD), Inter-Modulation Distortion (IMD), Direct Current Offset, Peak Phase Difference. Holding or decaying maximum values of spectra. The Demo version is a fully functional copy of OscilloMeter with the exception that input time is limited to 15 seconds after each "Start" button click. The registration removes demonstration limitation.

Sound Masker generates White, Pink, Brown , Purple and Blue noise. You can mix and match combinations and record the output straight to a .wav file, ready to burn to CD or Tape. You can save as many of your configurations as you like, so you may configure one to help you sleep at night and another to mask air conditioning noise throughout the day. The settings are totally configurable, so you can select exactly the right frequencies to acheive the best masking effect for your circumstance, then record the result. Uses include to block PC Fan noise, to block noise from air conditioning units and noisy neighbours. Can also be used as a sleep aid or to help keep conversations private in offices.

This Program can generate signals in accordance with the theories
of the researcher Royal Rife for use as a Rife Device.
Features:
- Uses standard sound card
- Generates Frequencies 20Hz-22kHz (sine/square/triangle)
- Pulsed signals with variable duty cycle 1-99% (R)
- Extensive scripting capabilities (Macros) (R);
- Preset storage and recall (now renameable!) (R);
- Change frequencies directly by keyboard, mouse button or slider
- Multi sound card support (R).
(R) = Registered version only
Scripting
Scripts (also known as Macros) are a powerful tool to program the Rife
Generator. Scripts are text files and can be written in any text editor (e.g.
Notepad). The text files should be saved with a .rts file extension.
Script Syntax Rules
Every Line is one command, and these commands exist:
Tone ? Generates a square wave signal
Pause - Pauses the sequence and waits for confirmation to continue from user
Rem ? For commenting, line will be ignored by the program
Delay ? Delays the script by a given number of seconds
Repeat - Repeats the complete Sequence (infinitely)
End - Ends the sequence
The last command of a script MUST be Repeat or End.

GlissEQ is an analog-style equalizer in PC VST plug-in format. The most
interesting thing GlissEQ offers is its dynamic equalization performance.
Using almost any existing equalizer, you always get what you have set:
e.g., if you specify a +6 dB boost at 100 Hz you get exactly a +6 dB boost
at 100 Hz, also visible on the spectrum analyser. GlissEQ offers a slightly
different approach. When you specify +6 dB at 100 Hz, you don't necessarily
get +6 dB of gain. Actual filter gain is adjusted dynamically according to the
program material you are filtering.
This `dynamic nature' of GlissEQ gives you a much more friendly, assisting
filtering experience. Boosting up the highs will not necessarily create the
fatiguing effect of overload. Instead, you will get a pleasant
transient-emphasizing effect bringing life and dimension to your track:
thus, GlissEQ sounds simply musical.
This transient emphasis works for every frequency you tune the filter
to: e.g., it can be useful at the lower and the mid frequencies to give more
punch to the track. Moreover, the strength of transient emphasis and the
overall filter gain adjustment can be controlled with a special 'Dyn'
control. In reality, this 'Dyn' control adds a whole new dimension to the
equalizer as you know it!
Beside this wonderful `dynamic nature' GlissEQ offers a built-in FFT
spectrum analyzer. Moreover, the spectrum of the track can be exported to
any other instance of GlissEQ thus making interchannel spectrum overlays
possible. This can help you to free frequency ranges in one track to allow the
instrument in another track occupying these frequencies breathe.

Voxengo is pleased to introduce a new PC VST plug-in called Soniformer. This plug-in is an innovative mastering tool for DAWs (Digital Audio Workstations) that allows the user to form and reform the sonic structure of any sound material. Many of our tests at Voxengo have revealed that even a professionally mastered audio track can be adjusted by Soniformer, resulting in a new level of sonic excellence.
The main idea behind Soniformer is a spectral balance. A perfectly balanced mix can be seen on a spectrum analyzer as a spectral curve with a downward slope towards the high end. There can be some deviations from this rule, but generally it always applies (at least the higher frequencies are usually less powerful than lower frequencies). Soniformer uses compression to adjust the spectral balance of any sound material being processed in a way that its spectral curve fulfills the aforementioned rule. Thus, Soniformer could also be called a spectral compressor.
Soniformer implements both compression and expansion, which allows a variety of different sound structures to be created, including classical tape compression, unobtrusive bass expansion, and general mix compression. And it all sounds pristine! One could say that Soniformer brings a classical warm analog compression to a digital workstation. This is true, because even at very subtle compression settings, Soniformer brings a strong feel of a professionally balanced mix. In fact, Soniformer allows the user to produce professional sounding mastering in a budget environment. Spectral balance is almost a universal thing, and every mastering engineer has to master it, while Soniformer brings it the easy way. Soniformer's adjustments of the spectral balance actually reveal details of the mix being processed.
