You gotta hear this to believe it! Penguin will let you tune his
creative international internal digital Penguin Band Scanner Radio.
It's a lot like Short Wave Radio, only the waves are Peguisonic.

Be a PWL'r (Penguisonic Wave Listener). Can you find Penguin
Newscasts in Penguinese? The blue display will show the radio band
numbers. It's fun to tune the random digital air waves! Every band
is different. What will you find tonight? - a goldmine or static?!

Hey! Where's the tuning knob? This is a VR radio! The tuner is all
Virtual Reality. Tuning is by turning Penguins body!

All of the Penguin stations are very unique! To vary Penguisonic
frequencies, use the virtual control knob, by moving Penguin around
in various cardinal directions. This will directly tune the bands.

The reception is proportionally directional. There's roughly a new
radio band scanned every 20 degrees. That's 18 bands of the most
unusual Penguin Radio!

humanoido -- your SEROUT for sound work is clever. I'm guessing you have more details about that elsewhere in some of your many penguin programs. Could you either point me to other programs that might have a detailed explanation of how you choose values for this kind of sound out, or explain it here, whichever is easier? Coo-el.

What the Smile does this program do? Use a digital compass as a 'tuner dial', and play funky sounds depending on what heading the compass is turned to?

Zoot, my only information regarding the SEROUT and various sound work can be found in the code comments for the various posted programs, and the Short Sound Tutorial information included here. There's over 550 sound related programs so far in the Penguin program suite, and most are posted. It's a lot to sift through so I've compiled a partial list given below.

A Short Sound Tutorial by Humanoido

Background into Sound Creation
A little background into sound creation - an important element is the waveform. Set up a Sound Oscilloscope to study and examine various sound waveforms and the effects of multiple channels with sound mixing. Multiple sound channels are created. A sound mixer is added. The resulting sounds are set by various baud rates to closely control the waveforms.

Sound Waveform Comparisons & Formation
Actual sounds can be recorded, played back, and the resulting waveform captured. This captured image is then compared to the code waveform formants and adjusted.

Methods of Sound Generation
For other methods of sound generation, not using the VSC Virtual Sound Chip, or otherwise, the baud was simulated. These techniques include FREQOUT, TOGGLE, SEROUT, code commands, nests, pauses, and other methods of making sounds and regulating the essential timing.

Keys to Complex Sound
The key to creating more complex sounds rests within these multiple channels and mixers.

The Nested Subroutine
Another key feature to mixing sounds is the nested subroutine because it has the capacity to regulate the timing to close tolerances and increase the number of sound channels. Be aware that anything placed within the nest is effectual to the waveform. It may be handy to create a timing guide to various code statements that will be located within the nest(s).

Sound and the Basic Stamp
Each basic stamp is a little different. So the sounds will be particular to the version of Basic Stamp microcontroller used. Not only the speed of the processor is a controlling sound element, but the statements execution time as well. These programs are particular to the Basic Stamp 2px and the Penguin Robot. There are Parallax manual guides for doing the conversions from one Basic Stamp to another.

The Sound Oscilloscope
There's a forum thread describing the sound oscilloscope and building a computer interface for it that should help. The sound oscilloscope is a virtual instrument free of charge that installs into a PC computer and has a speed range within the limits of the sound spectrum.

A Challenge
One posed challenge is to create sound that closely resembles the human voice. Penguinese includes such a subroutine. However, more work is needed to refine the results, making the effects more intelligible. In the future, a human speech language processor, created from these sound basics and a Basic Stamp microcontroller, is entirely possible.

More Information
For more information, consult the code comments and examine the sound code structure in the following programs:

This is an add-on note about compass calibration and
operating, which applies to all software utilizing the compass.

Within a 3-foot radius, the compass may report false
readings when near the following items:
computer, radio, speakers, and telephone, plus any
devices generating electromagnetic fields such as
electric cords, motors, disk drives, lights, etc.

When programming Penguin, it's a good idea to stretch
out the USB cable to the maximum length and locate
Penguin away from the computer using the radius rule.

A good tip is to use a simple analog compass to "explore"
the surrounding region and note any deviations in the
needle direction readings.
