Linear regression. The linear model Y = Ax + B

SynthPad Preview is a simple audio sampler for the PalmOS. You can record a single short sample, and then SynthPad will use simple synthesis techniques to let you play the sample back on any key of a one octave piano. SynthPad Preview can only run on Palm OS 5 handhelds (Does not yet work on Sony NX or NZ Clies).
To use SynthPad Preview, tap the "record" button in the top right corner. You will then hear a countdown to prepare you for recording (set countdown volume with "Game Sound" settings in your system Prefs). A dot appears next to the "record" button while recording. SynthPad Preview can currently record only a few seconds of sound.
A progress bar will then appear as SynthPad calculates new waveforms for each piano key. This version of SynthPad uses a simple linear interpolation process without filtering. Future versions may offer more sophisticated methods and may include "native arm code" to allow real time synthesis (no waiting!).
The original waveform will appear in high resolution. Once that waveform has appeared you can play the piano. Only a single channel is currently used, so you can not overlap notes, instead each note will interrupt the one currently playing.
You can also trim any "dead air" (silence) off of the beginning of your sample. Tap the pen where the sound begins in the waveform to set a "trim point". When the trim point is set (youll see a vertical line) a scissors icon will appear next to the "help" button. Tap the scissors and SynthPad will remove everything to the left of the trim point.
This is a free technology preview of products still to come from miniMusic. SynthPad requires a handheld or phone with a microphone. It has been tested on several Palm Tungsten and Treo models, but may not be compatible with some handhelds. This is a free sneak preview of products still in development, and we cannot guarentee it is error free (but we do have some experience with this sort of thing!).

You are FBI special agent Wolf Mouldie, and together with your partner Scowler, you must uncover the truth about paranormal activities.
This is a game of exploration, puzzles and paranoia! Less linear than Time Fracture with a limited amount of fighting. Three different but equally valid ends depending on the choices you make.
Requires Kyles Quest v3.2 to run. Level designed by Jane Britt.

EZConcept (Handera version) is a palm software to capture ideas, concepts and just about anything in linear or non-linear form.

It is specifically tailored for Handeras users to work with the larger and hires virtual screen.

It is designed to work with any handheld keyboard such as Pocket keyboard or Type N Go keyboard.

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.
