Use it to test your measurement equipment, apply signals as input to your electronic circuits. It doesn't end with electronic applications though. Use it to map the resonance pattern of a room, to calibrate a microphone setup or just to annoy your friends! It features all important functions of a real waveform generator.
-Friendly user interface: Similar to well-known professional hardware waveform generators.
-On the fly generation: No need to pause and restart the signal in order for changes to take effect!
-Sine, Square, Triangle and Saw waves
-Frequency Range: 1 Hz - 22050* Hz
-Save/Load waveform to/from internal memory, infinite slots!
-Request your own feature
-Square & Triangle wave Duty Cycle control
-Random Noise: White (Gaussian), Pink, Brown
-AM (DB and DSB-SC) / FM with Modulation Frequency and Level control
-Sine Sweep with Repeat and Ping-Pong
*Quality of high frequency waveforms might vary across devices.

Melody Generator uses a new theory of melody to automatically generate melodies, providing quick and easy assistance to composers and songwriters who need quick melody ideas, or to any music lover who just wants to play around. The current version of Melody Generator (Version 1) includes the following features:
- 8 bar melodies
- Time signatures: 4/4, 3/4, 2/4, 6/8
- Random chord progressions
- Random or custom key signatures (A, Bb, B, C, Db, D)
- Random or custom tempos
- Use of whole notes, half note, quarter notes, 8th notes, and 16th notes
The Melody Generator saves melodies as short MIDI files to your SD card, and allows you to browse through and listen to them after they are generated. Check out our website for sample output. Of course, more features are in the works!
Easy and fun method of creating music sequence with visual control!
- random tone patterns
- nice visual effects
- three samples (simple echo, piano and rock)
- faster and slower playback mode
- record and playback music (first version does not allow to save to files yet)
- zoom and pan support for smaller screens
Circularity does away with cumbersome user interfaces, keeping it to a bare minimum in order to maximize the work area. Notes are generated by circular beacons as they intersect each other's origins, based on the current radius of the triggered beacon.
The user may cycle through the three types of beacons by pressing down(and holding) any beacon.
Blue - expands and triggers sounds from blue and red beacons, then disappears
Red - has a fixed radius, can be triggered by any beacon, but can not trigger others
Green - similar to blue, but offers a steady pulse, can not be triggered
Three layers with different sounds are available and can be cycled through by pressing the rectangular corner buttons.
The tempo of each individual layer may be adjusted by pressing the circular corner buttons.
Circularity 2 has an organic theme featuring bells, drums and a chorus.
The features of the paid version are:
- no ads
- multitouch enabled
- multiple simultaneous sounds
Warning. Android devices can generate high volumes. Don't do anything foolish.
Launch the AudioGenerator application. The initial settings are for a sine wave at 440Hz with a 50% amplitude. The Play/Pause button can be pressed and a 440Hz tone will be generated. Pressing the Play/Pause button again will stop the output. Playing or paused, any slider or button can be adjusted to change the frequency, waveform, or amplitude. Note that audio outputs are AC coupled. The output creates a network with external devices such as ear-buds or amplifiers. The interaction with the devices and internal coupling is evident when a square wave

Now you can not install the player and use the standard system. For Xperia x10mini.., but the fit and the other.
Works only with external memory (sd-card).
Supports extensions: mp3, aac, 3gp, ogg, wav, wma, mp2, mp4, ape, flac, 3gpp.
It's is a simple sound generator that generates simple sine wave (20Hz-20kHz) or noise (white, pink and brown) that enables you to test the quality of the speakers (given that you know how a sine/noise should sound). Just connect your phone's headphone output with the amplifier input and press the play button.
The generator makes mono sound with support for various sample rates (8000-44100Hz) and sound buffer sizes.
NOTE: If you hear dropouts, that might mean that either your CPU is too slow (choose smaller sample rate) or you're out of memory (increase the buffer size). If you hear dropouts even on the most conservative settings (8000Hz sample rate, +100% buffer size), please let me know.

SOON TO COME: log scale, stereo sound, phase testing support, other generators, UI redesign.
-can cover a frequency range from 10Hz to 20kHz (actual range dependent on your audio hardware),
-exact tone generation, no messy approximation,
-*new* toggle for logarithmic slider,
-multiple wave types! Choose from sine, square, sawtooth and triangle,
-setting the frequency down to a single Hertz (and not 10 Hz, like in some other applications),
-connect external speakers to your device for even better sound and frequency range!
-Easy way to contact the developer: just press the "Report Bug/Suggest Feature" button and type away!
-option to keep the app running indefinitely,
-adapted for accessibility applications - easier to use for the vision-impaired.
Note: you can set the volume simply by using the buttons on your phone.
Internet permissions are needed for:
-ads (this is an ad-supported ad),
-feedback (you can report a bug or suggest a feature directly from the app),
