Hello,
I am using Debian GNU/Linux (Unstable) on my multimedia machine with a
M-Audio 1010LT and need to sample all 8 channels at the same time.
Which tool can I use for it?
I have tried Audacity but it does not work.
Note: I need the eight audiotrack in the same project and I must work
on them like in Audacity where I have all tracks togehther.
Thanks, Greetings and nice Day

Hi
I've just installed a RME HDSP PCI card and connected a Steinberg Nuendo
box "Multiface" but when i try to load the firmware i get following:
hdsploader - firmware loader for RME Hammerfall DSP cards
Looking for HDSP + Multiface or Digiface cards:
Card 0 : RME Hammerfall DSP at 0xdd000000, irq 3
Upload firmware for card hw:0
Hwdep ioctl error on card hw:0 : Input/output error.
Can it be caused by to long cables "my cable is round 4,5 meters" and
HOST indicator lights red ?

Hello list,
The situation is that I often transcribe audio signals (music of course,
but also spoken words like interviews) to my computer. Its a good
situation when your hands are free so you can use both hands to write.
I recently read about some expensive usb-footcontroller (USB) which
somehow connects to an audio program to send start/stop signals.
This cant be this complicated... there a plenty of midi controllers out
there which you controll with your food, even the sustain-pedal is
suitable for the start/stop job.
Do you have any Idea or know of anything which do the described? Just
sending a signal to a audioprogramm (audacious, audacity, xmms etc.) to
halt?
greetings,
Nils

I'm starting to enjoy glitchy percussion sounds I'm hearing in a lot of computer music these days, and want to experiment with those.
I've asked around about how people are making these sounds, and the answers I get are "Battery", "Redrum", and "Reason". All firmly wedged closed and proprietary. of course.
Are there any good free tools for making glitchy drum sounds, which do not require the use of WINE? If the answer to that is "SC/CSound/PD/ChucK", that's fantastic, can anyone point me to some particularly good source code or patches for glitchy drums in those languages that I could start experimenting with?
Thanks.

I experienced a strange problem in PHASEX where the BPM settings were saved in a patch file, but, when the file loaded, the BPM settings wouldn't.
The problem was that I had the "lock parameter" box checked in the MIDI map for that parameter (BPM). I don't remember if I set that, or if it is the default.
When "lock parameter" is set, not only will PHASEX ignore any updates from MIDI for that parameter, but also from the patch files. This could be kind of a useful feature, i.e. when playing a song and switching patches, often you don't want the BPM of the delay changing unexpectedly, just because you changed a patch.
However, when saving patches that go with a particular song project, you definitely *do* want the BPM to change when you load the patch. So I unchecked this, and I save that unchecked MIDI map with every project, so that the patch will load and have the correct BPM.
Saving MIDI maps along with the project is also a good habit to get into. It sucks to open a sequence and load a patch and the MIDI maps you'd recorded no longer do anything.

Fons,
Thanks for your reply.
Yes, the format is U8, it is a simple recording program to make '.wav'
files. The filtering does work when adjusting the 'silence byte'. It
appears that the device drivers are not consistent with this value?
So I will be adding an option to change the value of the 'silence byte'.
How do I use the RMS value to remove noise? A URL that I could read?
Thanks again for your time.

I need to write a small script to read all the metadata from a bunch of ogg files and save the exact same metadata into a bunch of corresponsing mp3 files of various bitrates.
I'd like to have this in either python or bash.
It seems there are about a dozen different competing tools and python libraries which may or may not be able to do this. If anyone can recommend one that will definitely do this, it would save me many hours of installing every possible option out there before finding the one that works.
Thanks!

Hello, This is my first post. I work everyday with
Linux at my job (Slackware). I was wondering what most
of the people on this list use as their main Distro
for Linux audio? I plan to use some form of multitrack
recording software as well as some sampling looping
software as well.
I have some older boxes that I was considering using
does anyone have advice on processor speed and system
configurations that work well?
I am also interested in knowing what hardware
interface work best for Linux audio?
Sorry for the fragmented post.
