The NCH Tone Generator

By Ken Adachi, Editor

If your computer has a sound card, this NCH audio tone generator can play audio tones through your computer speakers or earphones. You can set the frequency from 1 hz to 20,000 hz. Certain specific tone frequencies can modify and improve all kinds of health conditions. It's called Sound Therapy. If you wish, you can greatly augment this therapy by simultaneously applying Light Therapy, which is also simple and easy to set up.

I've included Frequency List 1 and List 2 with various health conditions and their associated tone frequencies that help improve those conditions. Just run down the list for the condition you want and make of note of the frequency or frequencies that you should apply. Set the generator for that frequency and press the start button. The volume dosen't have to be loud, just enough to hear it.

I've also added here a frequency chart of all the musical notes so you could also use an accurately tuned musical instrument as a source of  frequencies even if you don't have a frequency generator or a tone generator (

Instructions included with the NCH Tone Generator

Thank you for installing the NCH Tone Generator. The NCH Tone Generator (nchtone) is a simple but useful utility that lets you play tones using a Windows 95 or Windows 3.1 computer with a sound card.

To use the software follow these steps:
1. Select the desired wave form. The most commonly used wave form is the sine wave because it is the purest tone.

2. Enter the desired frequency. A range or 1 to 20000 is acceptable (1Hz to 20Khz). Note that the frequency is not relevant if the "White Noise" wave form is selected.

3. Select the sound card to be used to play the sound. If you have more than 1 sound card in your computer, select the appropriate sound card for the pull down list below the start button.

4. Press Start. The tone should play.

5. If necessary, adjust the Mixer Settings to change to volume of the tone. In Windows 95 run the mixer by double clicking on the speaker icon on the task bar. In Windows 3.1, run the mixer software supplied with your sound card.

This software is part of the NCH Audio Action set of utilities. These are a set of useful audio related tools for studio use, multimedia or business audio. Please visit our web page at or email us at for more information.
