[linux-audio-user] Using Terratec DMX 6Fire

by Sergi Roig

Hi, I'm new to the list so... hi to all. I decided to migrate 100% to linux from windows recently, just because I did't want to depend on commercial software anymore. I checked those hundreds of projects at sourceforge / freshmeat, and though that would fit my needs. I didn't say it would be easy though... :-P Mainly, besides normal desktop applications (OpenOffice, internet browser, and so on), I use my computer to transfer my old vynils to CD. My soundcard is a Terratec DMX 6Fire 24/96, which is exactly what I need (high resolution recording + preamplified phono input); the problem is that I can't manage to find out how the envy24control and alsamixer work. I don't know how to select the phono input for recording, and usually when I play music (even a CD or mp3 using xmms) it sounds distorted, kind of too "saturated". Is anyone using the same card? Would anyone give me a hand please? Thanks!

[linux-audio-user] ecasound 2.2.1 released

by Kai Vehmanen

1. A short summary of changes The JACK slave mode code has been completely rewritten. As a new feature it is now possible to use libsamplerate for resampling. Using JACK has been made more user-friendly as ecasound can now automatically configure the runtime parameters to match the current server settings. And thanks to build system and signal handling updates, it's now possible to compile ecasound for win32 under Cygwin. --- 2. What is ecasound? Ecasound is a software package designed for multitrack audio processing. It can be used for simple tasks like audio playback, recording and format conversions, as well as for multitrack effect processing, mixing, recording and signal recycling. Ecasound supports a wide range of audio inputs, outputs and effect algorithms. Effects and audio objects can be combined in various ways, and their parameters can be controlled by operator objects like oscillators and MIDI-CCs. A versatile console mode user-interface is included in the package. Ecasound is licensed under the GPL. The Ecasound Control Interface (ECI) is licenced under the LGPL. --- 3. Changes since last release * If configured with JACK-support, ecasound will now fetch the correct buffer size and sampling rate parameters from the JACK server when connecting a chainsetup with JACK inputs or outputs. In other words you don't have to manually match these settings between the JACK server and ecasound. * Support for Erik de Castro Lopo's libsamplerate resampling library added. If libsamplerate is not installed, ecasound will fall back to the old resampling algorithm. * Rewritten the code that handles JACK slave-mode operation. Ecasound is now able to more quickly and reliably follow transport state and position changes, as initiated by the current JACK timebase master. * Ecasound for Windows! :) With help of the Cygwin environment, you can now compile win32 ecasound binaries straight from the standard source package. As of 1.3.1, Cygwin also contains basic /dev/dsp emulation, so even audio playback works. * Fixed many, more or less serious, bugs. The most annoying ones were incorrect handling of the '-t' option, excessive DBC warnings with JACK inputs and outputs and failing to properly reset the terminal after a CTRL-C while in interactive mode. Full list of changes is available at <http://www.wakkanet.fi/~kaiv/ecasound/history.html>. --- 4. Interface and configuration file changes None. --- 5. Contributors Patches Junichi Uekawa (build system) Kai Vehmanen (various) Bug Hunting (items closed) Janne Halttunen (2) Eric Amundsen (1) Antti Boman (1) William Goldsmith (1) Andrew Reilly (1) Oliver Thuns (1) --- 6.

[linux-audio-user] Which soundcard?

by Robert Epprecht

I want to build a small home studio. I'm planing to record electrical and acoustical instruments (including voice). I already do have an external mixer (with mic preamplifiers). I do need MIDI and (maybe) SPDIF I/O. While I do think that about 6 analog inputs will do, I know that some more could become handy some day... Looking around in the net I have got the impression that both RME Hammerfall (PCI Interface + Multiface) and the Midiman Delta 1010 would be good (but expensive) choices and about equally supported in Linux. Do you think that these cards would be comparable regarding quality and Linux compatibility? Are there other suggestions to consider? I have seen some complaints about RME MIDI timing problems, but I do not think it was the PCI Interface + Multiface combination. Is that right? BTW: how long is the cable between PC and Midiman Delta 1010? How is the collaboration between M-audio/RME and the free software community? (we should honour this ;-) I know websites for Linux printer recomandations and such, but did not find something similar for sound equipment. Pointers welcome. Thank you for taking your time to share your experience, Robert Epprecht

[linux-audio-user] Non-low latency "playing around"

by Lonnie Borntreger

Before I go "all out" and build a low-latency kernel, shutdown 90% of my system, and run jackd and ardour as root.......... I would like to be able to just familiarize myself with the tools and technology. So, is it possible, and if so, what are options to give jackd for things like sample rate and such, that would work for a user in a non-low-latency environment that would allow me to run some of the plug-ins, ardour, and other jack enabled tools... kind of "test drive" if you will... without causing a system crash. Obviously, I wouldn't attempt to do any serious stuff until updating the kernel and all the other stuff. Thanks. Lonnie Borntreger

[linux-audio-user] Re: [Audacity-devel] Audacity supports jack in Agnula?!

by Daniel James

> Everyone needs jack, they just dont know it yet ;) Surely if Audacity is the only audio app running then it would be more efficient to access the alsa drivers directly? > If this is your feeling > then the right thing to do is to fix jack to make it less arcane. Ideas > welcome. It would be good if it could start and run as easily as other daemons - I know there are attempts being made to address this, such as jackstart. I guess it will be better when jack is fully integrated into distros, with the necessary kernel patches for capabilities etc. One of the main things that put me off using jack with audacity is that with the standalone program I didn't think I had any latency problems. I tried running jack and it told me I have xruns... Can jack verbose output be directed to a console so that you could check for xruns with ctrl-alt-f7 or whatever? I seem to remember trying this and it made the xruns worse! Cheers Daniel

i got my new Audiophile 2496 installed with Alsa 0.9.0rc5. i have an external A/D converter and the SPDIF light is lit, meaning that the card is working. alsamixer shows *lots* of controls. What do they all do? Can someone post a working /etc/asound.state? -- Victory to the Divine Mother!! after all, http://sahajayoga.org http://why-compete.org

RE: [linux-audio-user] Interuptions While Recording

I simply added -z:db (no numerical perimeter) and was able to produce 5 tracks of 16,2,44100 (5 minutes long) without a single interruption. > PS Sorry for not answering sooner to your query. I did read > your original mail on ecasound-list, but just didn't have > time to answer it... :( I've always trusted that you were just busy. Besides, I'm just greatful that you took the time (and continue to upgrade) ecasound.

[linux-audio-user] Sound on Sound, and Home Recording Magazine

by Darren Landrum

Two little things to tell everyone. First, I finally got my copy of the February issue of Sound on Sound. The Linux article is there, and I was very impressed with it. Plus, this issue has a great how-to on micing drums for studio recording. The surprise was the copy of Home Recording I picked up on a whim today, because it has an article on DIY surround sound. In the back, under the Computer Central heading, is an article called "The Other Operating System," by Thad Brown. I'll give you three guesses which one he's talking about. :-) It's a very positive article, saying that he ultimately thinks that Linux will be a serious competitor to MS and Apple for music production. The article also mentions a company called Digigram who has released drivers for their audio hardware under an Open Source license (does anybody know anything about Digigram?). He does say, though, that there seems to be no real replacement in the works for the likes of ProTools and Cubase, so I think somebody needs to point him to Ardour and Rosegarden. Just thought you all would like to know. :-) Regards, Darren Landrum
