    Update:
    The hardware is done. Now what is the hard part are the sound files. Will place a youtube link when complete from start to finish.

    I am very interested in your sound project. Just look at what DCC++ has already accomplished. Open-source experimentation is a great way to get improvements into the hobby, keep cost down, and most importantly bring new and younger people into the hobby.

    Just so happens that I have bought steam locomotive with a tender that is designed for sound installation. I plan on initially putting a cheap ($4) Bluetooth-sound-board in with the OS-DBTC hardware.

    Sounds like fun! (pun intended)
    I think the youtube link got munged - it shows Kanji characters

    For starters there are many libraries of sound effects. With more effort you might clip sound bytes from youtube. Not the decoder manufacturer videos, that would be wrong.

    OK, I made my last comment in early August, 5 months ago.

    So, now you say the hardware is finished, so you can answer these questions:

    1. What "quality" of sound are you going after?
    2. Your system MUST be polyphonic to some degree, so how many independent channels are you using?
    3. What power output and type of amplifier are you using?
    4. What bit rate are the sounds running at?
    5. How do you handle changes in load being reflected in the sound?

    All of this is hardware, so I'd like to know, or did you really build a "glorified MP3 player" with no ability to change speed, attack rate, synchronize with speed etc.

    It has been a while. Methinks he ran up against a problem he could not solve.

    Hey All,
    I did NOT hit a wall. One member rubbed me the wrong way and I took my toys and went home. In addition I work in the medical field. I am a home hobbyist and a new father. I've ran into several old guard electrical theoriest of days long past that can't wrap their head around all the new possibilities out there. I'll post some stuff upcoming to help people along using open source. That way nobodys work goes to spoil. The most difficult aspect I can say in this project or anything to do with sound is the coding. Everything requires condensing. If you are looking for help with animations or sound, please PM me.
