icon_atglite

"Audio Tone Generator Lite" is a free sound generator app. It creates the audio feference 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.

With the latest version, the UI design has been revamped to a brighter and more visible image, and stability has been improved.

Sinewave Mode

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

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.

Further, by tapping a preset frequency button can be set from four preset types. By tapping "PLAY" button, 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 can generate a sine wave of transitional frequency continuously in the frequency range from 20Hz to 20kHz.

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 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, 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 "PLAY" button, the noise generation will start. It stops the signal generation by tapping "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.
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.
