View Full Version : aacplus streams

We just got a fantastic new radio station here in Minneapolis (this is a
truly rare event in the U.S. since the corporate ClearChannelization of
America).
http://minnesota.publicradio.org/radio/services/thecurrent/

I can tune it in on my radio, but naturally I want to stream it on out
my squeezebox as well. The high-quality stream from "The Current" is
being done in aacplus. I've been poking around the web trying to figure
out how to make that work, but have run into nothing but dead-ends.

Anyone have any experience with this technology? Specifically, where to
get codecs for it? I'm running Linux, but I'm interested in feedback
regardless of OS.

cheers,

follow-up on my own post:

I can get aacplus streams to play locally on my Linux machine with VLC
(http://www.videolan.org/vlc/), but I'm stuck as to how to get the codec
from the VLC packages working with slimserver...

the quality of this low-bandwidth aacplus stream, btw, is exceptional...

cheers,

Ben,
I've also been listening to the new station today - great format and NO
commercials! I can get the feed to play in Winamp, but like you, no luck with
slimserver/squeezebox. Hopefully someone can figure it out, I was really
surprised how good the stream sounds.

Great station! Now the big question is how do we stream it to the
slimserver. On OS X I found only VLC to be able to decode aacPlus and I
assume it should be able to do the same on Linux. VLC can run without a
GUI and also stream so I wonder if it can be used in combination with
Slimserver. The secret is probably how to set the decoding in
convert.cnf. I hope someone can figure this one out.

Wow! That's some station. Holy cow!

They just came off a Nina Simone singing "My Baby Just Cares for Me" and
went straight into Radiohead's "Optimistic". They promise the new
Chemical Brothers single in a little while. Meanwhile they're playing a
track by Mum, an electronica group from Iceland, a track called "Green
Grass Of Tunnel". And now some Nick Cave.

Holy cow! This is what an alt-rock station is supposed to sound like.

I'm going to set up my usual Rube Goldberg system to stream it to my
Squeezebox (Winamp tuned to the station then feeding a local Shoutcast
server to reencode it at 320kbps MP3, then tell the Squeezebox to
connect to the Shoutcast stream). And then I'm going to send them some
money, become a member of Minnesota Public Radio. Something. This is
just too good.

Anyway, I concur: a more direct route to the Squeezebox would sure be
appreciated.

Does mplayer know how to play AAC streams?

FWIW, it is the FAAD2 package within VLC that provides the decoding of
aacplus streams. There is an xmms plugin for aacplus as well, but I
can't get it to output any audio...for now it's VLC. I have no doubt
there is a suitable stream to get piped out slimserver, it's just a bit
beyond my skills to figure it out.

FAAD2 is what I need for my Linkstation, any hints on how to
compile/install would be appreciated, my Mac has made me forget
whatever I knew about Linux. The source code for FAAD2 is available
at http://www.audiocoding.com/modules/mydownloads/

I gotta check out that station, thanks for the info about it.

I have faad2 installed but that is not enough. I also modified the
convert.conf file as described in the Wiki for aac files and added the lines

mov aif * *
faad -w -f 2 $FILE$


but that doesn't do it. I wonder if the entry "mov aif" needs to be
changed to something else to work with aacPlus vs aac.

convert.conf functions for files, not for streams. the handling of streams is
prgressing but it is much more complex as evidenced by the amount of
peoplehours invested in AlienBBC.

Umm... There are plenty of people who believe that Minnesota Public Radio is
responsible for the "ClearChannelization" of public radio. See:

Gordon-

I respect your opinion, and have followed this story closely as well.
However, I can't feel like MPR is a villain in this. St. Olaf decided
they didn't want their station any more. Want villains? Start with their
Board of Regents. MPR wanted to find a slot for a station with this
format in a totally jammed FM band, and they found it.

Also, it is a major, major stretch to say that non-profit public radio
is doing the same thing as Clear Channel. If you want to really get
incensed, I can send you a bunch of URLs offline about that company's
practices.

Sorry, Ben. I know that this isn't the forumn for this, but as an ex-WCAL
employee, and with lots of friends who still work in the non-MPR public radio
world in Minnesota, I couldn't resist.

Here's a recent article on the cost-driven growth of the format:

Try this stream to access The Current:

mpr-wm.streamguys.com/mpr?MSWMExt=.asf

It's not aacPlus but you can check out a great station.
