Yes Richard, the audio is coming from the amp/speaker on the Woody... generated from the computer. Free wave files. Electronics are 'off the shelf' digital (no tuning) wireless. The crummy radio crap amp/speaker is needed to boost the volume. i have about $80.00 in it. Unlimited audio files. Will play anything you have on your computer... Plug it into your computer headphone output jack.
The real treat is playing multiple audio files at the same time..... That takes a bit of software... nothing ground breaking, just a pretty fast puter that can play 4 or 5 audio files at the same time and a little code.
Collect all the egg liner audio files you can find that you might want to play..... send them from your computer to the egg liner.
Like I said in an earlier post.. You want to play Christmas music from your train? Halloween? Well, wireless digital audio has been around for some time..... Anything you have on your computer will play through a wireless digital receiver on your train. I did not invent it. I just like to have fun with it.
I picked the ole Woody because I am also digitally running it from the computer. The audio is synced to some of the operations....
Next? Bring video and audio back from the train to the same program through a wireless video camera and frame grabber...... Nothing ground breaking... Been doing it for automotive customers for years.
Why buy all those speciality control /audio functions.... all the power you will ever need is right under your mouse....... mouse click , whole different train, same electronics... different audio and control.
Think about it......
