What can you use a tone generator for? You can do a science experiment with resonance, tune a musical instrument, test your new audio system (how low does it go?), test the limits of your hearing (I can hear virtually nothing above 18,000 Hz, even at maximum volume), or figure out your tinnitus frequency to better target therapy. There are other tone generators on the Web, but they are not as cool (if I do say so myself) and/or they require Java or Flash. Works well on Chrome, Firefox & Safari – including mobile devices (iOS, Android) – requires a browser with support for the Web Audio API. JDiff is a Javadoc doclet which generates an HTML report of all the packages, classes, constructors, methods, and fields which have been removed, added or changed in any way, including their documentation, when two APIs are compared.Input frequency as a number (added Aug 2017).Choose sine/square/sawtooth/triangle wave (added Aug 2017) Other Android examples (source code examples) Here is a short list of links related to this Android ToneGenerator.Generate a link to a specific tone, so you can share it (added May 2016).Can change the frequency smoothly as you move the slider.Increase/decrease the frequency by one octave (added Aug 2015).Pick a music note from a list (added Sep 2014, revamped May 2016) I came across a similar issue while working on a project, I found that this assisted me tremendously: Beeping in Android (Custom Sound) Taking into consideration what they describe to you there, you can simply utilize a for loop, and execute the 'playAudio' function 3 times in order to get it to beep 3 times.


Fine-tune the frequency in 1 Hz, 0.01 Hz and 0.001 Hz increments.It’s basically a large logarithmic slider that allows real-time, smooth frequency changes. The results indicated that it is possible to execute an attack that intentionally increases the power consumption of Android devices and reduces the battery life. I made an online tone generator based on the Firefox Audio API HTML5 Web Audio API. As a result, we were able to reduce the usable time of the batteries of two Android devices to 3.1 h and 3.2 h, respectively.
