Audio Tone Generator Lite - Reference signal generator for Audio / Free of charge!

icon_atglite

"Audio Tone Generator Lite" is a free app that has simplified the sound generator function of "ATG - Audio Tone Generator", which creates the Audio Reference signals as Sinewave, Sinewave Sweep, White Noise and Pink Noise.

"Audio Tone Generator Lite" will help you to make the sound benchmark for your audio equipment and loudspeakers, your listening environment and room acoustics or your hearing.

The signals created by this app can be best used in conjunction with external devices, such as an audio spectrum analyzer or a sound level meter.

In addition, by having you to use it in conjunction with our Real-time Audio Analyzer app "fo-Kannon" or "Audio Frequency Analyzer", it can be easily measured the frequency response of your Audio system. Please use the "Audio Tone Generator Lite" app as the standard pink noise signal generator.

Top View

Top view has the operation setting area at the top, and the control area at the bottom.

In the control area, you can select one operating mode from Sine-wave mode(Sine), Sinewave sweep mode (Sweep) and noise mode (Noise) and Information view (Inform). In addition, you will be able to control the playback volume, Play/Stop.

In the operation setting area, you can see the parameter of the operating mode that has been selected in the control area.

At the first boot of this app, Information view is displayed, so please check how to use it.

Sinewave Mode

This is the Sinewave signal generation mode. It generates a single tone between 20kHz from 20Hz.

If you tap the frequency display monitor, it is possible to use the keyboard. In the keyboard input, you should set a frequency of 20kHz from 20Hz.

It should be noted that the initial application startup, the initial value does not set, it need to set an integer value of frequency.

Further, by tapping a preset frequency button can be set from four preset types. By tapping "PLAY" button in the control area, it generates a tone signal. It stops the signal generation by tapping "STOP" button.

Sweep Mode

This is the Sinewave Sweep signal generation mode.

It generates a sine wave of transitional frequency continuously in the frequency range of 20000Hz from 20Hz.

If you tap the frequency monitor display, it is possible to use the keyboard. In the keyboard input, you should set both the upper and lower limit frequency. It should note that the initial value is not set at the application startup, it need to set the integer value of both frequency.

In addition, by tapping a preset button, you can set from two types. There is two types of "PLAY" button that can be generated rising sweep and downward sweep. It generates a tone signal sweep by tapping "PLAY" button in the control area, and then sweep the full frequency range at 60 seconds. It stops the signal generation by tapping "STOP" button.

Noise Mode

This is Pink noise or White noise generation mode. At first select whether "WHITE" or "PINK" and tap the "PLAY" button in the control area, the noise generation will start. It stops the signal generation by tapping the STOP button.

White noise
The amplitude of white noise is constant throughout the audible frequency range.
Twice the power corresponds to 3 decibel increase, so white noise is said to increase 3 dB per octave in power.
Pink noise
Pink noise is filtered to give equal power per octave or equal power per 1/3 octave.
The power of pink noise per Hz of bandwidth decreases by 3 decibels per octave. When pink noise is chosen for equalizing auditoriums, the real-time analyzer can be set up so that they display a straight horizontal line when they receive pink noise.

Note

Please be careful that continuous high-volume and high-frequency signals can damage speakers, even if your ears don't perceive them as being too loud.
If the silent mode is turned on, all iPhone sound outputs are disabled. To enable the sound output, please be sure to turn off the silent mode in the iPhone' settings, "Settings/Sounds" or Control Center.
On the keyboard-input of frequency, please press the return key after entering a numeric value. Also, in the sinewave sweep mode, please press the return key after entering two numeric values continuously.
Wireless connection with Bluetooth equipment is not supported.
AirPlay data transmission is a wireless communication system using Apple's proprietary audio data compression. For this, there are cases where the random sound noise is generated by radio condition and the compatibility of AirPlay connection equipments. Note that it may occur at particularly high frequency band.
When using this application with wireless communication such as Bluetooth or AirPlay, there may be cases that limitation of the playback frequency, lowering the output level and irregular noise, etc., may occur under the influence of wireless environment, communication equipment and communication state. Please note that this is not to guarantee that this application operates as configured specifications under the wireless communication.
