The most efficient (in terms of memory footprint and resources used) audio player ever designed

Spoon's been at it again. Clicky here for details...

Thanks Struts.

Asset Control does indeed look promising and if it delivers the instant response Spoon promises it might be a killer app.

Looks like it may have a few icons you have to hover over which could put some off.

I see it's not yet fully developed but have you time to play with it any?

'Fraid not. We're out at the summer house now so I'm online via my daughter's netbook. I might have a play with it when we return to town in a month-or-so although as always there are several other projects that beckon!

My pleasure John.

While I have your attention I sent you a PM on the subject of hi rez downloads back in February but you never replied. Did you see it?

Also, I'd really love to hear your response to the comments and suggestions a few posts down in this thread.

Thanks in advance.

With apologies, but I think Music Player Daemon (MPD) has gotten it beat by more than a few years. Link: http://en.wikipedia.org/wiki/Music_Player_Daemon

Hey nyc_paramedic,

Wondered if you had any experience with or thoughts on XXHighEnd? There are now so many of these things that I for one have a hard time keeping up!

Re: The most efficient (in terms of memory footprint and resourc

struts,

Sorry for the late reply. I did not get an email that you had replied to one of my posts.

As for XXHighEnd, my household is strictly Linux, so i can't comment on any of the wares available for Windows or Mac.

Personally, I'm using Voyage Linux (based on Debian Linux) on a small single board computer that runs MPD (Music Player Daemon). Feeds a USB DAC. It's about as minimalist as you can get without going to an ARM architecture and using something like this: www.picotux.com/pt200/picotux200.pdf

Hardware Links:
http://www.pcengines.ch/alix3d2.htm
http://www.pcengines.ch/alix2d2.htm

Boards have no extraneous peripherals, i.e., no VGA, PS/2, parallel ports, etc. No need for an ATX supply either. Runs off any 7v to 20v supply. One can use a custom linear or batteries. I once powered the thing, playing FLAC, for over 8 hours using 8 AA Lithium cells. My Kill-A-Watt meter reads 3 watts when decoding FLAC.

Software Links:

MPD: http://mpd.wikia.com/wiki/Music_Player_Daemon_Wiki
Voyage Linux: http://linux.voyage.hk/

MPD is unique among the audio players because it uses the client/server model. That is, my mpd server daemon runs on the headless Alix board, and I control it from another device on the network. Thus, I can have a minimal amount of services running on the Alix and let my Nokia N800 tablet or Thinkpad worry about drawing a GUI and fetching album art. There are clients for Linux, Windows, Mac, Android, Android phones, Bluetooth, iPhone/iTouch ( http://www.katoemba.net/makesnosenseatall/mpod/), etc.

Voyage Linux was developed for small boards like the Alix. The entire OS loads from a 256Mb compact flash and runs entirely in RAM. My FLAC files are stored on my bedroom computer (Debian Linux), which acts as a simple NFS server. Voyage also keeps Debian apt package management system; no need to compile software. Just use the apt command to install your software.

I brainstormed this idea a few years back after Pascal Dornier (designer of the PC Engines boards) started releasing boards with USB functionality. I had already been using his Wrap network boards as a custom router/firewall. To me, the boards are a perfect fit for computer audio: dead silent; headless; runs the entire OS in RAM; low power/efficient; probably a lot less EMI/RFI compared to standard desktop boards/switcing supplies.

It's not terribly difficult to get all of this running. Nor is it expensive. This guy was a total newbie, and I got him up and running in a few hours: http://cheap-silent-usb-linux-music-serv...p;max-results=4

The future of computer audio is Linux. In one form or another.

Cheers,

Nick

P.S. I just picked up a new QB-9 from my local dealer. The one with the USB Audio Class v2.0 board installed. MPD, with a recent Alsa snapshot, plays 176/192khz flawlessly and beautifully. On the fly sample rate conversion from 44khz to 192khz.
