SoundTraxx brings more FUN to your model railroad through the magic of sound! Regardless of your scale or prototype, we have a sound system for you! We manufacture all of our digital sound decoders in the USA, right here in Durango, Colorado. Our professional sound engineers record and edit our sound files and test our decoders multiple times before we ship to ensure top quality.

Imagine a world where your model trains come to life with the most realistic and immersive sound experience. Blunami is a cutting-edge decoder that opens the door to customized operation. It's not just a decoder; it's a symphony of sound packed into a tiny package. Control with your favorite DCC command station, use the Blunami App, or ditch track power all together. Run your trains your way with Blunami!
