Output is 16 bit for each left and right channels and at 44.1kHz. Output will depend on your device hardware. Some device hardware may may filter out the DC bias and low frequency signals. At high frequencies, the waveforms will be distorted due to limited number of samples for each waveform (for example at 4.41kHz, a sine waveform will be approximated by only 10 points). Therefore this is for fun/educational use, for critical applications use a real calibrated function generator.
Left and Right audio channels can be assigned to either channel 1 or channel 2.
Sine, Square & Triangular waveforms.
Frequency range from 1 mHz up to 22 kHz.
Amplitude as percentage 0-100%.
Set duty for square waveforms or skew triangular waveforms to get saw waveforms.
Offset the phase of waveforms.
Sweep frequency or amplitude (Single, Repeat & Bounce modes).
Amplitude Modulation (AM).
Frequency Modulation (FM).

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!
Users are able to play custom synthesizers using the x-y axes of the touchscreen. The x-axis corresponds to amplitude (volume) and the y-axis corresponds to frequency (pitch). Playback can also be looped, recorded, and EQed using a Parametric EQ.
On top of performing, Users are able to create their own custom synthesizers, which consist of a custom timbre and user-defined effects. A small variety of timbres are included: Sine, Square, Saw, Pulse, Noise (white)*, Theremin, "Singing Saw", "Electric Eel", and "Starslide." These, as well as any user-created synths, can be mixed and matched at different harmonics, amplitudes, and phases to create custom sounds.
Each synth has customizable fx parameters as well, including Envelope (ADSR - attack & release), LFO (rate & depth), Delay (rate & decay), and Note Lag.
-Choose scale: Pentatonic, Major, Minor, Blues, or Chromatic
-Choose the base note for the pad.
-Control the grid size.
-Record to the SD card.
-Toggle visualizations. More to come here.
*I fully intend to make noise scale with frequency and actually become useful (e.g. "Red" Noise).
- SD card access: for saving instruments and recordings.
- Vibration: For haptic feedback.

SynprezFM 2 is also a Yamaha DX7 emulator, that can render with accuracy the sysex files you upload into an external storage directory setup by menu, in order to extend the experiment. You can also create and save your own patches, either by editing one of the (willingly) unsorted builtin ones, or starting from scratch with the "init voice" function.
It is possible to record WAV, connect a MIDI keyboard with split capability (an experimental feature for Android 3.1 and above, using USB OTG cable), and take advantage of a small step sequencer. Even small devices can now leverage 2 synthesizers thanks to an optimized layout. To simplify the classic usage, complex functions are now only available in "expert mode" (activatable in the setup page): this regards the patch editor and the new micro-tuning feature.
While you play, you can trigger an after-touch vibrato effect by dragging your fingers on the active keys or shift the keyboard to different octave. Other performance parameters can be accessed above the keyboard, including 2 types of portamento, a sensitivity range for pitch or volume modulations, and some effects that give a sense of depth when using a headset, especially on plucked sounds. You can also adjust the polyphony to adapt to your device capabilities. Thanks to an optimized core, you can hear up to 16 channels playing together, even on mid-range devices.

Features 1/1, 1/3 & 1/6 octave RTA modes, Leq (wideband, Octave, variable duration), RT60 (wideband, Octave), Spectrogram, Peak frequency, Fast, Medium & Slow filters, Flat & A/C Weighting and film industry X Curve, Averaging, SPL Chart Recorder, Noise Criteria, White/Pink Noise, Sine, Square, Triangle, Sweep, Ramp and Impulse signals & loudspeaker polarity checker, L/R select. RTA Store & Load, Hann windows, "Keep Screen On", pinch to zoom, scroll to center.
Exclusive ISO 1/3 Octave Calibration - correct for your phone's microphone response. Octave calibration discs are moved up or down to obtain a flat response, and match the overall SPL to that of an external meter. Save/Restore of Cal files (Dayton Audio iMM-6 also supported).
Use: home theater, audio engineer, car audio, etc
AudioTool FFTs sets of samples recorded at the microphone. Aliasing reduced by Hann windowing. SPL calculated in realtime. Spectra may be saved as files on the SD card, then loaded and displayed with the live spectrum. The "Store" button stores the current live spectrum - "Load" shows a list of stored spectra to select.
To hide the buttons, tap the screen. To restore them, tap again. To zoom the scale, pinch the screen. To move the scale, drag it up or down (left or right).
The deciBel meter uses IIR filters and exponential averaging to calculate Flat, A and C weighted response at speeds of Fast, Medium and Slow speeds.
A pair of cursors can be shown on the RTA and Chart Recorder displays: each can be moved to any position, and will display the SPL & time/frequency values there. Initially, both cursors are positioned mid-screen - simply drag them to a new position with the fingertip. The cursors can be turned on and off in the Menu.
The loudspeaker polarity checker can be used to check whether a loudspeaker is wired in phase: connect the AudioTool output to the speaker under test, select "Polarity" from the signal generator screen, then return to the RTA screen. If the speaker is out of phase (polarity reversed) AudioTool will show "Pol ---", otherwise "Pol +++" if the speaker is in phase.
The Noise Criteria (available from the Menu) function shows a set of NC contours overlaid on the 1/1 Octave RTA display and the calculated real time current NC value is also shown.
The Chart Recorder shows a moving trace of the SPL measurements over the last few minutes.
RT60 measurements can be made by starting the RT60 component using the "RT60" button, and then using a loud clap (or similar) to trigger the measurement. RT60 can also be used with Pink Noise from the AudioTool generator. RT60 times measure how much reverberation or echo there is in a room or auditorium.
The Signal Generator generates White and Pink Noise, Sine, Square, Triangle and Ramp waves, Sine Wave Sweeps and Impulses. The generator uses multiple cycled buffers, refreshed randomly so ensuring truly random White/Pink noise. Pink Noise algorithm uses Kemmet's method to adjust White into Pink.
The frequency accuracy of the generated periodic signals is typically around 1%. Sine wave fidelity is good throughout most of the audio range. Other signals' leading and trailing edges show ringing and decreasing frequency response artifacts in the upper ranges, depending on the Android used.

Welcome to Haunted, a massive multiplayer online lovecraftian ghostbusting game of horror!
Huge worldwide location base based on Google Places API.
Cooperative multiplayer combat.
Geolocation (GPS or network) powered.
Otherwise classic RPG :)
beta version (tested on Samsung Galaxy S1 and Note)
Players now receive xp reward for combat assistance. Also, the latest assists log may be viewed with "Show assists" button.
Mystery cases, superbosses, haunt percentage and the number of agents present on a location are now displayed on the map.
The nearest mystery cases are now listed as AGENCY RADIO when in map mode. You may also click on them to zoom the map on the location.
The fog may now only be encountered in the deepest level of the dungeons that has been discovered so far on the location.
Skill checks and other kinds of random events are now tougher and more rewarding in lower levels of the location.
Ectotraps may be used to trap a (single) phantasm and handcuffs may be used to arrest a (single) mortal enemy. If more in a group, you may only attempt that after reducing the number to one. Arresting a mortal now renders you a written or recorded confession and 1 or 5 (rare) glory points. 5 glory points for trapping a phantasm, 15 for trapping a rare phantasm (actual numbers subject to change in the future). Trapped phantasms and confessions also gain more mystery points when analyzed.
Arresting/trapping is done in the following way. Use the ectotrap or handcuffs respectfully to trap a phantasm or arrest a ghost, while in combat. You may only attempt that when no more than one enemy is still standing. Also, using an ectotrap or the handcuffs will imediately eliminate them from your inventory. Until the end of that combat, your attack will be less efficient, but if you defeat the enemy, it will be trapped or arrested. However, the final value (in terms of mystery points upon analysis, or any other effect they may have) of the confession or the trapped phantasm will depend on how many health points it has left the moment when the trap/handcuffs are first used.
A powerful trapped phantasm or superboss remains may now gain you a permanent extra skill point instead of mystery points when analyzing them. The chance is slim but increases with more
Instead of mystery points reward, certain kinds of evidence (rings, daggers...) may turn out to be rare items upon analysis. This will also depend on relevant player skills, like investigation, occult or science.
"Analyze all" converts all your evidence into mystery points in a single analysis sweep. If any of the evidence turns out as some other kind of reward (item, skill point etc) the sweep analysis is halted at that point, so no more than one such event will be reported at the same time.
New kinds of mysteries, such as celestial, weather and paranormal sighting events.
More ways to combine mysteries, new kinds of combined cases (conspiracies, infestations...).
Superboss banishings, arresting rare mortal enemies and trapping rare phantasms are now reported in the news.
