New low-cost DSP platform in development
- Thread starter bachatero
- Start date
The only other dynamic (ie automatic, level-dependend) loudness feature I've seen was on an active speaker (Buchardt, I think). I've heard JRiver can do it, but I'm not sure how the level-sensitivity could be programmed.
Roon bridge is Linux, tho, right?
I see conflicting things about Roon Bridge (not Roon) being open or closed source.

I think all the room software is closed, I thought the RAAT protocol was open, but when I looked yesterday I now think I made that up. There are open source airplay projects.
While it is true that there are open source airplay projects (the best known is probably shairport-sync), they are based (at best) on reverse engineering Apple protocols. The result is a limited feature set (see for example https://github.com/mikebrady/shairport-sync/blob/master/AIRPLAY2.md) and - if you were to use it in a commercial product - legal risks.
My DIY DSP rig is in a 3d printed enclosure. But I used petg and a fan. No problems.
If you expect things getting hot, abs is even better, but it is not that easy to print. If you aren't adding an amp inside I wouldn't bother.

There may also be a cheaper, bare bones version available with just the built-in stereo audio, and you use the USB port to plug in "real" hardware that you already have. So why not just buy a Pi Zero instead in that case? Because like the regular version with optical in/out, this will be a "complete" solution with a pretty enclosure and everything for those too lazy to make their own.

My original hype post
Myself, I don’t do Linux based DSP because I’m not a big Linux fan, and I like near-instant boot times.

There is a huge difference between "desktop Linux" like you might use on a PC or Raspberry Pi and "appliance Linux" where you see nothing except the appliance functions. The idea is that my DSP devices would have the latter so you don't have to worry about "Linux stuff" at all 
Not totally the same, but may I introduce you to one of my favorite open sourced projects?
3D printed parts, custom electronics, a big ol' discord, incredible value. They are very successful in their little circle and I bet there's a lot to learn from how they handle such an unuruly project.
FWIW, a reliable RPi 2x4 or 4x8 hat that remained in stock with like 90dB SINAD would be a game-changer.

You will notice, if you haven't yet, what 100 potential users will have 100 different requirements when it comes to audio inputs and outputs. If it was me, i would leave a header in the basic module to which one can later attach different audio i/o hats. keeping the USB of course.

Of course, because otherwise anybody could just mess with it if it's on a shared network.
Here is a mockup of the home screen:
Any thoughts on it?
