NCH Sound Tone Generator is a software that allows users to generate audio tones, sweeps, or noise waveforms on a Windows PC or PocketPC handheld with a sound card.

The software features a range of waveforms including Sine wave, square wave, triangular waveform, saw tooth waveform, impulse, white noise, and pink noise. It also supports frequencies ranging from 1Hz to 22kHz bandwidth, subject to sound card. Additionally, users can create multiple simultaneous tones (1 to 16 tones) to generate harmonics, and choose between mono or separate stereo operation that is ideal for creating dual tones or 'beats'.
The software also offers the option of generating tone sweeps (log or linear), and users can choose to play the tone or save it as a wav file. Tone Generator is available from NCH Software for Windows, Intel Mac, PPC Mac, Pocket PC, and Palm OS, and it integrates with WavePad, RecordPad, and MixPad.
