Features:
- Sinewave signal generation : Preset / 500Hz, 1kHz, 4kHz, 16kHz
- Frequency Sweep of Sinewave signal generation : Preset / 200Hz - 4000Hz, 20Hz - 20000Hz
- Direct frequency input from keyboard. (in 1Hz accuracy)
- White Noise and Pink Noise generation.
- Supports of frequencies range between 20Hz to 20000Hz.
- Output Gain Control.
- CD Quality Output.

Applications:
- Testing for Loudspeakers and Headphones.
- Testing and tuning for Audio amplifiers, Equalizers and many other Audio equipments.
- Acoustics testing.
- Frequency response measurement for Audio systems using White noise and Pink noise.
- Sound Masking.
- Relaxation and Meditation by using 1/f noise (White noise).
- Hearing Test to find the maximum frequency that you can hear.
- Mosquito sound creation for teenagers.

Note:
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 continuously two numeric values.

Please be careful that the high-frequency signals of high volume in continuous may damage the loudspeakers, even if your ears do not perceive it as being too loud.

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.
