Free sound frequency software for pda

Family Radio Service (FRS) radios are now becomming more popular than ever. Originally found only at Radio Shack, they are found everywhere else, such as Wal-Mart, Fred Meyer, etc.
Recently, I was at a local Wal-Mart and decided to read the advertising on each type of FRS radio. These radios do NOT provide secret communications! Advertising shows info like Tones, Channels, Codes, etc.
Well, you can go to your Local Wal-Mart or Radio Shack or your favorite department store and buy a low-priced Radio Scanner... This database file reveals the actual frequency of each FRS channel. There are only 14 FRS channels. (One radio included a few GMRS channels)
Thanks for enjoying the benefits of the Palm Operating System!

Sound Grenade 1.2.1 is an open source tool which gives you instant crown control. That party get a little bit out of control. Sound Grenade is the answer. Plug your iPod touch or iPhone into some speakers and crank up the volume. Sound Grenade generates a really, really annoying, nauseating and headache producing high pitched sound.

Enhancements: Includes improvements.

Sound Tester lets you enter up to 10 sounds and play them one after the other.
Each sound is made by entering the frequency, duration and amplitude of the sound.
Enhancements:
- Added "Rest Note" and "Reset All Notes" buttons, and test a single note.
System requirements:
- Palm III
- Palm OS v3.1

Sound? by Questions plays songs defined as text.
Short and easy to use, but powerfull. No polyphony is implemented at the time.
Usage:
- Composing the music
- Creating music with running titles (song score)
- Generating tones - so you can use this like a tuner
- Generating beats - so you can use this like a metronome
- Testing sound efects for games
- Having fun.
Main features:
- Exact tempo generating (standard PalmOS note lenght setting in 1/100 of second is not exact enough).
- Double volume setting - you can set volume for each note separately (velocity) and for whole song - both are combined
- Music debugging - you can see what note is curently being played.
- Looping, playing selection.
- Powerfull phrase repeating
- Music titling - title is changed as music plays.
- You can use standard Cut/Copy/Paste operations - song is just a text. You can send it with mail.
- MemoPad support - songs are stored in MemoPad database, so you can synchronize them with desktop.
- Built-in help and command reference with examples.
- All this in less than 10 kilobytes of code.
System requirements:
- Palm III
- Palm OS v3.0

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.

This is a program for testing your pdas sound for errors.

This was a modified source code originally form HelloWorld included in the HsPascal Demo Folder.

Audio tone generator. Generates single frequency, sequenced, sweeping up or sweeping down audio frequencies, adjustable duration and volume. Possible uses: - audio circuit testing, PC sound card / DSP testing, effect generator, tuning of musical instruments and testing customer owned Outside Plant (OSP) cabling.
System requirements:
- Palm OS 3.0 or later
