Many thanks, Alex. I'll use this instead. Researching the whys of midi
not playing in Firefox etc can wait ;-)

You reach the point, when I'm unable to resist to reply ;).
1. The German Wiki about this bullshit says, that "Dolby-Surround" "is"
compatible to everything, e.g. stereo. It "will" sound as wanted, when
played in stereo.
http://de.wikipedia.org/wiki/Dolby_Surround
2. ½ of 180° phase shift * (1,41/2) should be ok in stereo :D? That's
theory.
Anyway, among other jobs I worked as an video and audio engineer for a
well known German filmmaker and professor. "Dolby Laboratories" are a
mafia. If you make movies using light audio for cord ("celluloid" or
equivalent material ;) you'll notice some un-shy wow and flutter. You
need to pay a lot of money to use Dolby to avoid this issue, no sane
film maker does, excepted of those who are antisocial and take all the
money they can get from furtherances. Dolby comes back for more, to
cheat people, so they invented all that surround bullshit, that does
sound odd.
Any "material" encoded by that kinds of "film Dolby" belongs to /dev/0.
I experienced Dolby C as a very good procedure for maintained analog
homerecording audio equipment, but that's another story.
Dolby for audio is the equivalent to Apple and Microsoft for computers.
They are robbers. They do some good jobs, but most they do is
"business".
This CD belongs to the hazardous waste, it's that simple.
2 Cents, YMMV,

Hello everyone!
I've got a CD, which says, it's mastered for dolby surround. When I ripped
it and listened to it, some passages sound very quiet. Is there a way, to rip
or encode the tracks to 5.1 or whatever they would be, so I can have a better
listening experience? Please don't suggest any GUI-software, since I CAN'T use
it. Thank you.
Kind regards
Julien

If so, the signal wouldn't be compatible to mono ;), everything would be
lost in "2 channels added to mono" and they claim to be backward
compatible. Just playing one channel can't work, since they do hard
surround effects, so there's the need to add both channels to mono.
The whole theory is grotesque. Dolby surround can't sound good, since
there's no way to handle all the standards that way.
Just got one -_- it works out of the box in usb 1.1.. in theory it
should also work in usb 2.0.. or that depends, what is the state of
usb2-audio on linux? if it's ok this litle thing should work in some way..
It's a real nice piece of hardware, the smell off quality is allover..
the only bad thing is that -15dB PAD's and phantom power is controlled
with dip switches wich aren't really accesible by hand..
So, does anybody know the state of usb2 audio on linux? it's supposed to
work in usb2 on newer macs without 'external' drivers...
And does anybody know how to set the default soundcard by name rather
than a number on archlinux. I've tried this;
https://wiki.archlinux.org/index.php/ALSA#Random_Lack_of_Sound_on_Startup but
I really can't seem to get it working..
Does anybody have any idea for a device
(smartphone/tablet/netbook/mini-pc...) that could run jackd and thus be used
as an effects processor or synth module?
I really don't know where to look, but the idea intrigues me. It should
probably be something with a usb port, in order to connect midi stuff or an
external audio card.
Any idea?
Hello,
Funny how topics will intersect sometimes (referring to the Dolby
thread). Poking around on my drive yesterday, I found some old files
someone must have given me claiming to be DTS, but with a wav extension.
File, sndinfo, and ffmpeg all claim the files to be 16bit 44100 stereo
files, but playing them only results in a burst of noise. Is there a way
to transcode these files so that they might become just plain stereo?
Looking around brings up ffmpeg as the way to do it, but, as I said
earlier, ffmpeg doesn't seem to recognise these files as DTS.
Thanks.
Cheers,
S.M.

Hi all,
I've had a lot of little problems with my ubuntu recently so i decided to
get it reinstalled.
First I went for the last version but I didn't really like the unity
desktop. Had a lot of little annoying things on my laptop such as not being
able to set a brightness setting that wouldn't be reset at boot. All in
all, i decided to go back to gnome.
As I didn't know what older version to chose and as I was pretty pleased
with my Lucid, I went back to Lucid;
Now my problem is I need a rt or lowlatency kernel (2.6.32 or higher) to be
able to set up my laptop properly because I use some pretty original
settings to make the best out of my machine.
But now I can't find any... :(
I looked in abogani's and falktx's ppas but nothing there.
So my question is simple, which version of ubuntu should I choose to be
able to enjoy a good audio workstation with a corresponding rt or
lowlatency kernel ?
Second question, if I wanna stick with lucid where can I find the
lowlatency or rt kernel (2.6.32 or higher) I'm looking for ?
Thanks in advance

Hello!
In a month or so I'll for the first time in my life attempt to master two
smaller EPs (my own music should be added). I've worked up a fairly good
skillset with some parts of the mastering (multiband compressing etc) but I
need some major help with tips for what I'm trying to accomplish, which is:
* I want a similar soundlevel throughout the whole of the EP, eg. I want
the songs to be similar in strength even if they are dissimilar in
dynamics/type of song. Some songs are naturally more "aggressive" and thus
will be a bit stronger, but I want the climaxes in the more easy going
songs to be as strong.
I realise that most of this will be done through the traditional "just
listen and compare", but I'm wondering if there are any other
analyzingtools that might ease my work a bit? Like analysing RME for the
whole song, will that give a fair indication that can be compared amongst
songs? Fatigued ears and the need for alot of small breaks is calculated
with, but those difficulties will be pretty testing for me I think with my
low patience lol, so anything that makes the process easier is good stuff!
Mastering on my own like this probably isn't that good, I know, but I'm
looking at it as an opportunity to learn some tricks of the trade.
I will be using plugins from linuxDSP together with a few Calf ones and the
Foo Limiter, so no Jamin etc.
Do you have any general tips for me etc? All tips I can get are greatly
appreciated!
Thanks in advance, regards,
