Introduction to NCH Tone Generator
Introduction to 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. Tones created by nchtone can be used as a sound source to test equipment, to align equalisation, or to set recording levels.

To use the software follow these steps:

1. Select the desired wave form. The most commonly used wave form is the sine wav because it is the purest tone.

2. Enter the desired frequency. A range from 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 or press the enter key. 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.

If you use the software often you can add a shortcut to "c:\nchtone\nchtoner.exe" assuming that "c:" is your primary hard drive. If you want the tone to start automatically when the tone generator runs at the "/start" argument. For example create a shortcut to "c:\nchtone\nchtoner.exe /start".
