One more:

The convert.conf file is the basic rule file. It will be overwritten with every update/upgrade, which makes sense, since options of the used programs such as Sox and mplayer are changing once in a while.

BTW: The Squeezebox Server Package carries some binaries, such as Sox. This way they can guarantee that the rules work. However this can also mean that the SB server is running a different binary from your distro supplied binary.

You'll find the binaries here: /usr/share/squeezeboxserver/Bin/i386-linux

Now: To avoid that your settings are overwritten all the time, you put above 3-liner "ogg pcm," rule into a new file called /etc/squeezeboxserver/custom-convert.conf
instead of putting it into convert.conf.

That should be it.


Another one: It is obvious that you could even use brutefir to run convolution in a squeeze network following the same method. You just hang brutefir into any of the
pipes/rules.

Cheers

Interesting product at that price level. Still it has quite some limitations. The first two that hit my eye: samplerates x*48, slopes 24db only.

This little board you could perfectly combine with a Squeezbox Receiver ( even via I2S header) to build an active crossover - if 44,1 would be supported.

You need to edit /etc/convert.conf and add:

Code:
ogg pcm * *
  # R
 [mplayer] -really-quiet -vc null -vo null -bandwidth 10000000 -cache 128 -af volume=0,channels=2 -ao pcm:nowaveheader:file=/dev/stdout $FILE$
..
Thanks for this tutorial, I was struggling with these streams before, want to report here, that I managed to make it sing on XP PC via SqueezeSlave (ASIO) as well, used mplayer executable for windows (SMplayer package), followed these instructions: SlySoft Forum - View Single Post - ReClock chitchat


Since you are such a resourscefull bunch of audio fans here, I'd like to ask you about another very related topic, is there an easy way to make SqueezePlay (and possibly Squeeze Server web interface) show cover art pictures, which are regularly being updated on radio streams? What exactly is needed, a plugin, or config tweak, more?

Let's take example of this fine swiss radio (128k mp3): LOUNGE-RADIO.COM ...this is how we lounge !
Here is the frame which updates the cover art: http://www.lounge-radio.com/code/pushed_files/now.html

If you look at the source of this frame, the images are loaded in the following format:
Code:
 
<div id="covercontainer"><img src="playlist_sam342/az_B7202206_dub philosophy_alpha & omega.jpg" width="125" height="125" title="Album: dub philosophy by Artist: alpha & omega"></img></div>
So, what we need is just take the non-changing address: "http://www.lounge-radio.com/code/pushed_files/"

and now add the filename of covert art from the currently played track located here under id="covercontainer", for our example:

+ "playlist_sam342/az_B7202206_dub philosophy_alpha & omega.jpg"

=> so these two combined result in the full path to cover art in full available
resolution (~300x300) for a given track:

"http://www.lounge-radio.com/code/pushed_files/playlist_sam342/az_B7202206_dub philosophy_alpha & omega.jpg"

Click the image to open in full size.

Any ideas? Thank you

FYI, Daniel Mack is actively working on USB audio 2.0 alsa drivers, the progress is fast.

[alsa-devel] usbaudio: Support for USB audio v2.0 devices

Jaroslav Kysela has introduced an alsa upgrade script, and asks for testing the script on various distributions

Great! eagerly waiting for it...

BTW: is USB 2.0 audio always async or are there more than one option?

Anyone here try Linux Mint? It is the newest music friendly Realtime Kernal to my knowledge. I iso'd a dvd and wish to install it on a 640 gig HDD.

Hi Al.

I do run Mint. And promote it since quite some time.
I still consider it the best entry into the Linux world. Even experienced Linux people can pretty well live and enjoy Linux Mint - I do.

However.

Mint neither comes with a default realtime kernel nor it is optimized for audio as you'll find it with e.g. Ubuntu Studio.
What it comes with are so called non-free codecs ( medibuntu repository), which you' won't find on a basic Ubuntu system.
Regarding audio and codecs you can consider Mint Plug'n play. ( as long as your soundcard is supported)

It is no rocket science though to install features and applications and a new kernel on a Linux system, if it is available in the so called repositories.
You can easily install all software by the Software manager resp. Package Manager if available in the respective repos.

It just takes some pretty simple configurations to get Mint up to speed for rt-kernel scheduling and performing equally good ( I think even better) then e.g. Ubuntu-Studio.

To take advantage of a realtime kernel you

a. have to install it first (package linux-rt)
b. you need to grant the users rt-permissions
c. you need to have an app supporting rt-scheduling.

E.g. Jack, ecasound, VLC, pulseaudio, brutefir, xmms perform best under realtime conditions. they all support a scheduling variant called SCHED_FIFO.


Cheers

Thx for the info.

I just had a quick look at it. It seems to be done for designers from a designer.
There is only very limited use ( if any use at all) for a normal user.
From that perspective I consider it pretty useless for us. That's really a pity.

Lets hope that this is just the beginning of this exercise and of getting Alsa upgrades disconnected from the kernels. Hope that one day Alsa gives the distro maintainers reasonable tools at hand to do the upgrades easily without messing with the system.

Nevertheless, things are going into the right direction. Let see how things are developing.

(BTW: Do you know Jaroslav?)

Cheers

Default Thanks for your reply

I am building a new rig soon and want to dual boot windows and Linux, Windows first, I'm still researching how to dual-boot. I had openSuse 11.0 on my last rig but it wouldn't play nice when I tried to install Vista Ultimate. I have the 64 bit Vista Ultimate and will use it on my next rig. I run 32 bit for now. Any tips on dual-boot?
