Free 2.1 surround sound systems software for pda

OL Systems 1r1 is a potential and easy to use tool to create minimalistic 0L Systems on your Palm PDA. A 0L System, or more formally a L System, is a string rewriting system which produce a long string to be interpreted as commands for a LOGO turtle.

Sound building tool to create a series of sounds and build sound effects of unlimited duration.

Input the Frequency, duration, and volume and simply add them to a list. It is extremely simple and time effective.

Not only does it let you design your own sound effects faster but it has a tool to help you find system sounds and track them.

Also in v1.5 a new feature is a wav player to play/test your wav files for your benifit.

Sound tester 1.5 is a must have for frequency based sound design

Untested on lower resolution

This app is freeware so feel free to share it with anyone.

I would love for you to email me with reports and requests. Thanks and have fun!

0L Systems is a simple implementation of a 0L System renderer. A 0L System, or more formally a L System, is a string rewriting system which produce a long string to be interpreted as commands for a LOGO turtle.

Some sound files in WMA format are included to help you calibrate your headphone, loudspeaker, headphone, Hi-Fi and related audio equipment.
"ever_rising1.wma" and "freq_sweep.wma" consists of a tone that increase in pitch endlessly. The harmonics are designed to fade in from the bottom and fade out at high pitch. It is the equivalent of the visual ever rising staircase. An audio perception paradox. Its application is in the checking of audio equipment frequency response. As the harmonic peaks sweep through the spectrum, you can see the locations of resonant peaks. A peak profiling line that holds the most recents spectral peaks for more than 3 seconds will give a stable peaking envelop which is the frequency response curve of the loudspeaker system.
"intermodulation.wma" consists of two sine waves of 1KHz and 1.1KHz. If the amplitude response of the loudspeaker system is perfectly linear and there is no saturation or amplitude distortion in any part of the system, then there are only spectral peaks at 1KHz and 1.1KHz. Other wise, you will find other spectral peaks, notably at 1-n*0.1KHz, 1.1+n*0.1KHz, 2.1KHz, 2.1+/-0.1KHz, +/-0.2KHz etc..
"sine_all522.wma" consists of sine waves of 1KHz, 2KHz, 3KHz, 4KHz and 5KHz having same amplitude. Under ideal condition, they should create 5 equal spaced spectral peaks in an audio spectrum analyzer. For the overall system having flat response, the 5 peaks should have the same height. If it does not, the problem may be due to one or more of the pocketPC output, any external amplifier, speaker, microphone, signal amplifier, and analogue to digital converter. It is also possible for one part in the system to compensate for imperfection in another part, such as the equalizer or equalizing amplifier.
"square.wma" is a simple 100Hz pulse. It can be used to see the step response of the overall system. A stable triggering of the waveform is needed.
To use the files, select it in a MediaPlayer. Also select looping or repeating mode of playback. Then you can begin to play the sound file. Most players create an artificial silent time between repetitions. The ears can detect this easily. But the program can skip over the silent period if we choose the long-time average mode. For accurate frequency measurement, the narrow band analysis should be used. However, the wider shape of spectral peaks for wide band analysis makes peaks easy to identify and measure.
Normally, you will connect your earphone output to the audio equipment under test. Then you bring the pocketPC near the speaker of the system, and run a spectrum or spectrogram display porgram while the Media or MP3 Player is running in the background. Some Media Players amy not be able to produce continuous sound even within the time span of the sound file, which cannot be used.

For everybody convenience, we prepared additional Sound Packages that allow you to add more fun sounds in the one Setup program.
All packages are ready to download from the above servers, all of them are password protected (password is the same like TurnMeOn registration code and case-sensivity).
Dla wygody kazdego, przygotowalismy dodatkowe wersje tzw. Pakietow Dzwiekow, ktore pozwalaja w latwy sposob dodac caly zestaw dzwiekow do programu.
Wszystkie Pakiety sa gotowe do skopiowania z powyzszych serwerow i sa zabezpieczone haslem (haslo jest takie samo jak Kod Rejestracji zakupu pelnej wersji program TurnMeOn Pro 2.0.) The Polish Movies Package:
Panie no i kto za to placi?
Malzonka sie niepokoi!!
Na pieszczote to trzeba zasluzyc.
Pociurlalibysmy se, co?!
O! O! Czlowiek!
System requirements:
- Any Pocket PC, TurnMeOn Pro 2.o.

Reversi or Othello is a well known boardgame. Its easy to play, but a challenge to win - and this version is a real challenge!
The board consists of 8x8 fields, the two players alternately put white and black stones onto the board. Your goal is to have the most stones at the end of the game. To do so, directly enclose your white opponent horizontally, vertically or diagonally.
All surrounded stones become yours - change to your black color. If you cannot surround stones, you have to pass. The game ends if the board is full or you and the computer have to pass.
The program individually fits boardsize to your Phones screensize, works in color, grayscale or black/white, playable on each Java Phone with at least 200 KByte Heapmemory (and 64 KByte linear accessible, older Siemens not). You can use 2,4,6,8 or joystick to move the cursor, press 5 or fire to place your black stone.
Main features:
- 6 different levels (Weak, Moderate, Normal, Good, Strong and Hard, the "Normal" level was tested with many other Phone Reversi Games without losing)
- shows your Move- Possibilities (optional)
- shows last Computer- Move
- animated stones (optional, if you have problems deactivate it)
- first Move for Computer or Player (startposition commutable too)
- really quick calculation and strong AI
- shows Time- Bar during calculation
- really small, only 16 KByte
System requirements:
- Symbian devices.

This application allows you to set or record your tones and system sounds easily. Tones can be set from any folder on your phone or storage card
