How to generate audio test tones with NCH Tone Generator 3.02




To generate audio test tones with NCH Tone Generator 3.02, you need to follow these steps:


How to choose the waveform, frequency, amplitude, phase, and channel of the tone




To choose the waveform, frequency, amplitude, phase, and channel of the tone, you need to follow these steps:


  • Select a tone from the tone list or click on Add New Tone to create a new one.



  • Choose the waveform type from the drop-down menu. You can choose from sine wave, square wave, triangular waveform, saw tooth waveform, impulse sound wave, white noise, or pink noise.



  • Enter the frequency of the tone in Hz or use the slider to adjust it. You can also use the up and down arrow keys to increase or decrease the frequency by 1 Hz.



  • Enter the amplitude of the tone in dB or use the slider to adjust it. You can also use the up and down arrow keys to increase or decrease the amplitude by 1 dB.



  • Enter the phase of the tone in degrees or use the slider to adjust it. You can also use the up and down arrow keys to increase or decrease the phase by 1 degree.



  • Choose the channel of the tone from the drop-down menu. You can choose from left, right, or both channels.



How to add multiple tones and create harmonics




To add multiple tones and create harmonics, you need to follow these steps:


  • Click on Add New Tone to create a new tone with different settings.



  • Repeat step 1 until you have added up to 16 tones in total.



  • To create harmonics, you can set the frequencies of the tones to be multiples of a fundamental frequency. For example, if you have a tone with a frequency of 440 Hz, you can create harmonics by setting other tones with frequencies of 880 Hz, 1320 Hz, 1760 Hz, etc.



  • You can also adjust the amplitudes and phases of the tones to create different effects such as beats or interference.



How to play, save, or export the tones as wav files




To play, save, or export the tones as wav files, you need to follow these steps:


  • To play the tones through your speakers or headphones, click on Play Tones or press F5. You will hear the tones according to your settings. You can also pause or stop the playback by clicking on Pause Tones or Stop Tones respectively.



  • To save the tones as wav files on your computer, click on Save Tones As Wav File or press F6. A dialog box will appear asking you to choose a file name and location for your wav file. Click on Save and your wav file will be created.



  • To export the tones as wav files for other applications or devices, click on Export Tones As Wav File or press F7. A dialog box will appear asking you to choose a file name and location for your wav file. Click on Save and your wav file will be created.



How to use audio test tones for various purposes




You can use audio test tones for various purposes such as:


How to calibrate and test audio equipment or speakers




To calibrate and test audio equipment or speakers, you can use audio test tones to measure the frequency response, distortion, phase alignment, and other parameters of the sound system. You can also use audio test tones to identify any problems or defects in the sound system, such as noise, hum, crackle, or buzz. To do this, you need to follow these steps:


  • Connect your sound equipment or speakers to your computer or device that has NCH Tone Generator 3.02 installed.



  • Generate a sine wave tone with a frequency of 1 kHz and an amplitude of 0 dB. Play the tone and measure the output level of the sound system with a sound level meter or an app on your phone. Adjust the volume of the sound system until the output level is about 85 dB.



  • Generate a sweep tone that goes from 20 Hz to 20 kHz in 10 seconds. Play the sweep tone and observe the output level of the sound system with a sound level meter or an app on your phone. The output level should be constant throughout the sweep. If there are any dips or peaks in the output level, it means that the sound system has a poor frequency response or resonance issues.



  • Generate a square wave tone with a frequency of 1 kHz and an amplitude of 0 dB. Play the tone and listen to the sound quality of the sound system. The square wave should sound crisp and clear without any distortion or clipping. If there is any distortion or clipping, it means that the sound system has a high harmonic distortion or a low dynamic range.



  • Generate two sine wave tones with frequencies of 1 kHz and 1.1 kHz and amplitudes of 0 dB. Play the tones and listen to the sound quality of the sound system. You should hear a low-frequency beat that varies from 0 Hz to 100 Hz. The beat should be smooth and steady without any fluctuations or interruptions. If there are any fluctuations or interruptions, it means that the sound system has a poor phase alignment or a high intermodulation distortion.



  • Generate a white noise or pink noise tone with an amplitude of 0 dB. Play the tone and listen to the sound quality of the sound system. The noise should sound uniform and balanced without any hiss, hum, crackle, or buzz. If there is any hiss, hum, crackle, or buzz, it means that the sound system has a high noise floor or a low signal-to-noise ratio.



How to demonstrate audio principles to students or others




To demonstrate audio principles to students or others, you can use audio test tones to illustrate various concepts and phenomena related to sound waves, such as frequency, amplitude, phase, waveform, harmonics, interference, modulation, and effects. You can also use audio test tones to show how different types of sounds are perceived by human ears, such as pitch, loudness, timbre, and masking. To do this, you need to follow these steps:


  • Connect your computer or device that has NCH Tone Generator 3.02 installed to a projector or a screen that can display the tone settings and the waveform.



  • Generate different types of waveforms with different frequencies, amplitudes, phases, and channels. Explain how each parameter affects the shape and characteristics of the waveform.



  • Generate multiple tones with different frequencies and amplitudes. Explain how they form harmonics and how they affect the timbre of the sound.



  • Generate two tones with slightly different frequencies and amplitudes. Explain how they create interference patterns and how they affect the pitch and loudness of the sound.



  • Modulate the frequency or amplitude of a waveform with another waveform. Explain how this creates modulation effects such as vibrato, tremolo, chorus, flanger, phaser, etc.



  • Add effects such as fade in/out, echo, reverb, etc. to a waveform. Explain how they create spatial effects and how they affect the quality and realism of the sound.



  • Play different types of sounds such as music, speech, noise, etc. Explain how human ears perceive them differently based on their frequency spectrum and temporal structure.



How to perform hearing tests or acoustics testing




To perform hearing tests or acoustics testing (under medical supervision), you can use audio test tones to measure your hearing threshold or the acoustics of a room or a space. You can also use audio test tones to train your ears to recognize different frequencies and amplitudes. To do this, you need to follow these steps:


  • Connect your computer or device that has NCH Tone Generator 3.02 installed to a pair of headphones or speakers that have a good frequency response and a low distortion.



  • Generate a sine wave tone with a frequency of 1 kHz and an amplitude of 0 dB. Play the tone and adjust the volume of your headphones or speakers until the tone is barely audible. This is your reference level.



  • Generate a sweep tone that goes from 20 Hz to 20 kHz in 10 seconds. Play the sweep tone and listen carefully to the changes in pitch and loudness. Note the frequencies that are most audible and the frequencies that are least audible. This is your hearing curve.



  • Generate different types of noise such as white noise or pink noise. Play the noise and measure the sound level in different locations of the room or the space with a sound level meter or an app on your phone. Note the variations in sound level and the presence of any echoes or reverberations. This is your acoustics profile.



  • Generate different types of tones with different frequencies and amplitudes. Play the tones and try to identify them by ear without looking at the tone settings. Note your accuracy and speed in recognizing the tones. This is your ear training score.
