I have a recording from a lecture. It was recorded in a large
auditorium and of course it show in the recording. I'd like to process
the recording to get a more intimate sound. It there any way of
reducing that ballroom echo a bit? If it can be done with a ladspa
plugin so much the better.

This is what happens: the data is read from the file via the filesystem. The
IDE/SCSI/Firewire/USB controller will do error detection & correction when
data is passed from the disk to the controller. Through DMA, this data will
be stored in memory. This buffer is the buffer which your soundcard uses as
a memory mapped output buffer. (There might be DSP phases between reading
the signal and storing it in the output buffers, but let's forget about that
for now).
Now, this output buffer is the same place in memory where your DA unit reads
data to convert into an analog signal. The source of the data inside the
memory has no impact on where the data is. The jitter of the data source has
no impact on how the data is stored in the buffer. This is pure digital
copying, all done with error correction.
I can write a piece of software which will read a signal from file(s) to
this buffer, and compare them to eachother. If the files are copies of the
same data, the signal in the output buffer will not differ. At all.
After this phase, the DA unit will convert the data to an audible signal.
What the DA unit does with the data is totally independent of how the data
in the output buffer has been gathered. At this point, jitter or other
differences between data sources have no effect on how the DA consumes the
signal.
The hard drives do _not_ produce any reading or writing errors, because
otherwise your system would be totally unusable, as the programs you are
running to read this email would be broken and incapable of performing their
duties.
The whole of computerland depends on one thing: predictability. Without
this, no computer system would work at all. The same error detection &
correction which makes your software work, will keep the audio data (copies
or not) correctly on disk.
Let go of your anxieties. You can make perfect digital copies of your
sessions, and that will not make any difference in how they sound. Why do
you think the RIAA is after us all? :)

Hi.
I put I question the ardour-users list about running jack over a LAN
and the answers and some googling point me here.
I have two computers laptop and headless_server.
1) From laptop launch ardour on headless_server through SSH tunnel.
(Already got this part working)
2) Get ardour to output its audio to a jack server that is running on laptop.
I realize that jack.upd and jack.plumbing are involved in this second
step. But other than that I'm pretty lost. I've read the man pages but
have no idea what to do with the information.

...and you know what's really weird? The DeMudi used to
boot up OK with the same CD player, when I first burned it to CD - then it
began to hang at 'storing language'.
Anyway, think I should try a new CD player...

I upgraded to a Delta 1010 over the weekend (from a M-Audio 2496).
Everything works fine (didn't even need to re-install any drivers)
except that, with envy24control, the digital mixer doesn't work, when I
select it for output there is nothing going to my monitors. SPDIF in and
PCM out all work.

Very good. I applaud your choice. But, kindly remember, it is your choice.
You should have no right to decide what I do with my music or software. If you
share my music or software without my consent you are taking away my ability to
decide what to do with the fruits of my labors. For the puposes of this
discussion the fact that I do share my software and music under open licenses is
not really relevant.

I tend to think that sharing music over the internet is probably good for CD
sales but again, it's not our call to make. We didn't create the content and we
don't have the right to decide what can be done with it. I deplore what the RIAA
and the MPAA are doing but mostly because I think they're being amazingly stupid
about the whole thing.

The 'Musix031.iso' jack latency is impressive. I think it's gonna be a distro
to watch. It would be nice if Audacity was already jack'd though...
Best,

Hello *,
I am working professionel (not as musican) and like to use a program
like rosegarden, but without KDE and GNOME. Because I must maintain
all of my computers my self and make backports and own packages (I am
working under Debian) I do not want to maintain tonns (86 MByte) of
EXTRA packages from KDE, which deinstall in the same time my half
workstation (I hate those monsters of KDE and GNOME and using only
fvwm which works perfectly since 1999).
Is it possibel to compile rosegarden without KDE?
If not, is there another equivalent program?
Greetings
Michelle Konzack

Sure sure. Thanks for clearing that up, and sorry for continuing the
mis-information. ;-)
