It is useful for:
- Testing subwoofers, speakers and amplifiers for frequency range and frequency response.
- Taking a hearing Test (test your friends and family).
- Testing your new headphones (can they output 20Hz as written in the box?)
- Sound Wiki: The app teaches the user the use and names of the various sound ranges.
- Some users use it to treat tinnitus !
- 16bit PCM encoding (CD quality)
- Sampling rate at 44100 (CD quality) or 48000 Hz (on supported devices)
- Tone generator
- Sweep tone generator
- Time span select-able
- No ADS!
- No PERMISSIONS !!
The KISS Principle (Keep It Simple Stupid):
My goal was to design and program a simple app that does the job, and not full off options that would introduce bugs and turn the app difficult to learn an use. But this not means that this kind of app if easy to do.
Test your phone's speaker, headphones, subwoofers, speakers and amplifiers.
Test your hearing.
- Variable frequency tone generator
- Sampling rate at 44100 (CD quality)
- 16bit PCM encoding (CD quality)
- Time span selectable
Extra features: Anti Mosquito and Dog Whistle (or Cat Whistle).
Anti-Mosquito: the ultrasonic Mosquito repellent generator emits a very unique high frequency sound (ultra sound) that most mosquitoes find distasteful and prevents you from getting bitten by mosquitoes.
Dog Whistle: train your dog to do tricks, train your dog to stop barking, or if there is a dog next door, use this app to make it silent.
Test the bandwidth of your phone's speaker (or your ears...), create true uncorrelated noise.
Make sure to check out our Spectral View, RTA and other apps in the Market.

Additionally these carrier signals can be AM, FM or PM modulated or swept in frequency. The modulations can be enabled on their own or in any combination.
The square and triangle signals have a duty-cycle that can be set from 1% to 99%.
The ArbGen app adds frequency resolutions below 1Hz, automatic and customized saving of all parameters and the arbitrary function generator.
The app is bilingual in German and English and has App2SD, where the app is very small.
It is possible to save the 5-tone combinations.
Now: Save as wav-File, register und use als ringtone!

Is easy to tune the instrument.
Various experiments with a wide band of frequencies is available.
Frequency setting: C, C #, D, D #, E, F, F #, G, G #, A, A #, B
Warning: This sound by the frequency of the sine wave is generated in real time. So the sound is very large.
(Not a wave file.)
Do not close your ears to the sound.

You need to dial number then press the button "Dial"
1. Dial the number
2. Put your smartphone near the microphone of your phone then press "Dial"
If it doesn't work, plug earphone on your smartphone, put an earphone near of the microphone and press "Dial" again.
*** OUTPUT ***
Visualization is done on real like device that shows:
- Audio level
- Noise Level
- Current frequency
- Frequency oscilloscope
- Time to Frequency chart
*** ACCURACY ***
Application is calibrated with real tone generator. Internal microphone limit is around 1800 Hz, but under this frequency accuracy is very respectable +/- 0.5 Hz.
*** NOISE LIMIT ***
You can easily set a limit that removes noise treshold with included trackbar.
*** EXPORT ***
You can export TTF chart to comma-separated file that you can later analyze with MS Excel or other table processor. Application has file directory browser with Save and Overwrite feature.

please dont be so harsh on the rating i am trying my best and spending alot of time on it also keep mind that google has made it really hard on jellybean devices to make changes to its audio download send me feedback on my email firstname.lastname@example.org thank you for downloading.
- Sine, square, triangle, sawtooth waves and linear, cubic, exponential sweeps and white, pink, blue noise.
- Rectangular, wedge and circular enclosures, sealed or ported, calculates dimensions given the material thickness, volume and port specs
Enclosure response graph
- Determine the relative gain of the enclosure, based on the T/S specs of the subwoofer.
- Gives values and schematics for crossovers given load and frequency (High, low, bandpass, narrow bandpass crossovers and Zobel filters).
Wire Gauge Calculator
- Automatically calculate length, load, gauge or number of runs by inputting 3 out of the 4. Also includes a list of wire specs for common gauges.
- Calculate the relative decibel level around the device.
(PLEASE NOTE: This is limited by the hardware. The microphone is designed for capturing voices (300-3400Hz). Outside this range, the microphone is not as responsive.)
Amplifier gains calculator
- Given the rated specs of your amplifier, you can properly set your line output to eliminate any clipping.
Ohm's Law Calculator and Common Equations
- Calculate Voltage, Amperage, Wattage or Resistance by inputting 2 of the 4. Includes most common equations for car audio (components in circuits, area and volume of shapes, enclosure specs, waves, etc)
Resistor value finder
- A visual tool to calculate the resistor value given the resistor band
LED resistor calculator
- Find the correct resistor for an LED to run on any voltage circuit
Speaker wiring calculator
- Find the final load of any series/parallel speaker circuit, given the voice coils and impedance. Wiring diagrams for most common setups.
Audio Control has 5 components: Profiles, Schedules, Exceptions, Quick and custom Vibration. Each provides a unique way to control how your phone sounds and behaves.
A complete tutorial with screenshots and videos can be found at: http://www.mobiletrialware.com/audiocontrol
The purpose of Audio Control is to allow you to create and manage unique audio profiles and switch between them with ease. When a profile is applies all the sounds of the device will change to match that profile.
Three optional plugins are also available for purchase: Location, WiFi Access Point, and Charging. These plugins will give you the ability to apply audio profiles in the most simple ways possible.
★ Separate Notification and Ringer volumes for ICS/JB devices (turn on this feature in settings)
★ 13 Widgets that are completely customizable
★ Schedule all device sounds by day and time
★ 10 Shortcuts to access any part of Audio Control or apply a profilep quickly
★ Profile widget that is resizable and can have multiple instances
★ Download FREE custom widget background or make and share your own from the developers website
★ A separate speakerphone volume for when the speakerphone is too loud or quiet
★ Profiles for Headsets (Bluetooth and Wired)
★ Locale and Tasker support for scheduling by location and more!* (Requires Locale or Tasker app)
★ Complete Tutorial so you don’t miss out on anything
★ Tablet optimized
★ Car Mode Profile
★ Never miss a text or phone call "Exceptions" which will auto adjust the volume
★ Adjust the device volume settings for a short period of time with "Quick" great for meetings or naps!
★ Custom vibration patterns for any installed application (ICS+ only)
★ Attach a ringtone to an Audio Profile
Profiles are a way to save and restore audio profiles, with one tap put your phone on Silent, Vibrate, Loud, Sleep, or whatever you can imagine.
Schedules provide a way to apply your audio profiles by day and time. For example apply a Sleep profile every night before bed. Or a work profile before you arrive to work.
Quick will apply a profile for a short pre-determined time and then apply a different profile when that time is up. Useful for those quick meetings the boss surprises you with.
Exceptions are a great way to never miss a phone call or SMS (Text) message. Add a contact to exceptions and when they contact you a profile will apply just moments before so you don’t miss them. "Go SMS Pro" not supported.
Widgets and Shortcuts are a great way to access any part of Audio Control from your home screen. Apply a profile with only one click! There are lots of widget and shortcut options to choose from, so don’t miss out!

The arbitrary signals are built from basic mathematical functions and operations. All entered functions and options are automatically saved and recalled. Additionally they can be saved and recalled in user defined profiles.
The free FuncGen app has most of the same functionality except for the arbitrary signals and the save and restore functionality.
