Reference Audio Test Signal tools. Try to check your sound system by your iPhone!"Audio Tone Generator" is a high quality Reference Audio Test Signal Generator application for the iPhone. This app is the high precision edition of "Audio Tone Generator Lite" app. It creates the reference Audio test signals as Sine-wave, Frequency Sweep, White Noise and Pink Noise, and has a high precision of CD quality and a frequency accuracy of 0.1Hz. Frequency Sweep time can be altered as desired by the user. From the version 3.0, it has been added a new feature of the band-pass filtering on NOISE generation mode. It will help you to make the 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", it can be easily measured the frequency response of your Audio system. Please use the "Audio Tone Generator" app as the standard pink noise signal generator.TOON,LLC is a company that seeks the comfort of sound environment based on our acoustic proprietary technology, and we will provide tools for audio professional, sound technology, home theater installer, and anyone who loves audio.

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.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.Please visit our iOS App Support page for more information on this app.
