Tap the Play button to generate a tone signal, and the Stop button to stop playback. This mode generates a pure tone signal with a sine wave.īy tapping the frequency button, you can set from 4 different frequencies with a single touch. In the operation setting area, you can set the parameter of the operating mode that has been selected in the control area.Īt the initial startup of this app, product information (Info) will be displayed, so please confirm how to use it. In addition, you can control the playback volume (Volume), Output channel (LR/L/R), Preset settings (Preset) and Playback control. In the control area, you can select one operating mode from Sine wave (Sine), Sweep signals (Sweep), Chirp signals (Chirp) and Noise signals (Noise) and Information view (Info). Top view has the operation setting area at the top, and the control area at the bottom. Burn-in for Audio equipment, Loudspeakers and Headphones Acoustics testing Frequency response measurement Sound insulation level measurement Indoor sound field distribution measurement Reverberation time measurement Sound masking Relaxation and meditation Hearing Test Top view This app can be very useful for a variety of applications including: Testing for Loudspeakers and Headphones Testing and tuning for Audio amplifiers, Equalizers and many other Audio equipment. Output channel selection: LR/L/R Output phase control: 0/180 degree - In-phase/Out-of-phase. Playback time control: 30sec/60sec/2min/3min/15min/60min Output gain control. Chirp signal generator (Chirp): Short-time sweep signal (transition time: 0.1 - 1.0sec, start delay time: 1 - 10sec, frequency variation curve: Linear/Exponential) Configurable frequency range: 20Hz - 21kHz Frequency input by keyboard in units of 0.1Hz. Octave band noise generation by 1/1 or 1/3 octave-band filer (center frequency: 63Hz - 8kHz / 50Hz - 10kHz), burst playback with duty ratio of 10/25/50/75%. Sine wave Sweep tone signal Warble tone signal Chirp tone signal Colored White Noise (White noise, Pink noise, Brown noise, Blue noise, Purple noise, Gray noise) Octave Band Noise (1/1 octave band, 1/3 octave band) Features Sine wave generator (Sine): Sine wave signal (Preset frequencies: 200Hz, 1kHz, 2kHz, 8kHz) Frequency Sweep generator (Sweep): Sine wave frequency sweep/warble signal (Preset frequencies: 20Hz - 20kHz, 200Hz - 2kHz, 2kHz - 8kHz, transition time: 30, 60, 120, 180sec), up-sweep/down-sweep playback Colored Noise generator with Octave-band Noise (Noise): White noise, Pink noise, Brown noise, Blue noise, Purple noise and Gray noise. This app can generate the following signals. Products Information Version : 3.0 Release date : OctoUTC Size : 0.7 MB Category : Utilities, Music Recommendation : Compatible with iPhone. App Store is a service mark of Apple Inc. iPhone, AirPlay is a trademark of Apple Inc., registered in the U.S. It will be open the download page on AppStore TM.Ĭommunications charges when connecting to the App Store will be borne by the customer. Please to click the following link to see the app information on AppStore TM. 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. It will help you to make the benchmark for your audio equipment and loudspeakers, your listening environment and room acoustics or your hearing. The latest version supports iOS 17 and improves stability and performance. ![]() ![]() Chirp signal generation time and start delay time can be adjusted. Frequency Chirp generator: It is short-time sweep signal with linear or exponential frequency change, and adjusts start and stop frequencies by 3 presets and keyboard input. Burst noise can also be output with 4 different duty ratios. Multiple selections of arbitrary bands are possible. It can also generate 1/1 and 1/3 octave band colored noise with user-configurable frequency octave-band filter. Colored Noise generator with Octave-band noise: It produces White noise, Pink noise, Brown noise, Blue noise, Purple noise and Gray noise. Frequency Sweep generator: It has linear sine wave frequency sweep/warble signal, and adjusts start and stop frequencies by 3 presets and keyboard input. ![]() Sine wave generator: It includes sine wave generator that generates a pure tone with a high precision of DVD quality and a frequency accuracy of 0.1Hz, and sets a frequency by 4 presets and keyboard input. It has four types of signal generators as follows, and can generate sine wave signal, frequency sweep, chirp signal, colored noise with octave-band noise. This app can be used in a wide range of fields as a reference sound source for audio system testing, sound tuning, hearing testing and more. "Audio Tone Generator Plus" is a new integrated sound signal generator application that produces a variety of audio test tones.
