[linux-audio-user] Testers for beta version of meterbridge wanted

by Steve Harris

this is not an offical release http://plugin.org.uk/meterbridge/meterbridge-0.9.2.tar.gz The release cycle has slowed down a lot, so I wanted to make sure there aren't any subtle regressions before announcing it. I've fixed a couple of major bugs, and reduced the CPU cost slightly, but there are no new features. - Steve

Re: [linux-audio-user] Laptop/Ozone usb keyboard

by Clemens Ladisch

The "Device Firmware Upgrade Specification" describes a vendor- and device-independent way of downloading a firmware image to a USB device. Older USB devices from Midiman (MidiSport interfaces, KeyStation keyboards) required a device-specific firmware loader, but when a device implements the DFU specification (such as the Sonica or the Ozone), it is possible to use one loader for all these devices, so user's don't have to wait until somebody manages to write a loader for their device. (Of course, now you have to wait for somebody to write the DFU loader, but that's only once. :) Regards, Clemens

[linux-audio-user] command-line recording software?

by Tim

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I want to record audio from my USB port and seek a command line or reliable and simple GUI app. Can anyone suggest what might suit me? I have Edirol UA-1A USB interface which is seen as /dev/dsp1. I intend to record 80 minutes of stereo music on my laptop. The laptop suffers overheating so I need something which uses minimal CPU activity. Otherwise I'd be using Audacity. I'm unable to even compile this software due to the overheating.

[linux-audio-user] looping music that i play

by Peter Jay Salzman

hi all, i'd like to: * record a single chorus of "girl from ipanema" on my accoustic guitar. * play it endlessly in a loop while i practise jazz improvisation. * it would be nice for my computer to provide a metronome while i play (and record that metronome over my recording), but that's not necessary since i can use a real metronome and have it play in the background. i went to dave phillip's site, and found a staggering number of recorders and players. can someone suggest a nice easy to use set of tools to do this with? as a first stab, i tried sound-recorder, but when i play the resulting wav file with wavp, wavp exits immediately. when i try to play the resulting wav file with "play", it complains about premature end of a wav file. i assume thousands of linux using musicians are doing exactly what i want to do. what are some good tools that i should look at? looking for ease of use rather than features, at least for now. thanks! pete -- GPG Instructions: http://www.dirac.org/linux/gpg GPG Fingerprint: B9F1 6CF3 47C4 7CD8 D33E 70A9 A3B9 1945 67EA 951D

[linux-audio-user] Laptop/Ozone usb keyboard

by Atte André Jensen

Hi I'm thinking about getting a laptop mainly for live performance using softsynths (PD, Csound, something like that), but would also like to be able to use it for multitrack midi and audio recording. I guess the answer to "what laptop to buy for softsynths" is "the faster the better". Unfortunately I'm on a budget, but I'm very interrested in what kinda performance I can expect from various processors, clock speeds, amount of RAM etc (very vague, huh?). For instance I sac a Fujitsu/Simens AMILO running 2.0 GHz Celeron with 256MB of RAM. Would that be an option? Also I'm interrested in the Ozone USB keyboard, since it's compact and would give me audio/midi interface and some kind of controller. How is this thingy supported under linux? Is there anything I overlooked? Aspects to take into account? Other software to look at? Webpages to go to? Thanks in advance for any feedback! -- peace, love & harmony Atte

[linux-audio-user] [ANN] QAMix - MIDI controlled Mixer for ALSA

by Matthias Nagorni

Hello, the first version of my new QT based mixer for ALSA is available from: ftp://ftp.suse.com/pub/people/mana/qamix-0.0.1.tar.bz2 The mixer GUI can be configured with an XML description file. Default files are provided with the tarball. See the README for more. At this occasion I would like to also announce QARecord, a simple but multithreaded stereo recording tool for both ALSA and JACK. Version 0.0.9 fixes a bug in the level meters. ftp://ftp.suse.com/pub/people/mana/qarecord-0.0.9.tar.bz2 Have fun !

[linux-audio-user] [PATCH] envy24control widget limits, version 2

by Ross Vandegrift

Hello, The first version of my patch had a few glaring errors. This update fixes the following issues: * HW In level meters were broken * The last PCM Out meter was broken * S/PDIF channels can now be controlled with -s, --spdif * The Patchbay/Router and Analog Volume tabs now accurately reflect the number of requested channels in all cases. This update does not include the requested vertical layout changes. If I have the time, this is on my TODO list. The patch against 0.9.3 is included below, and available from http://poplar.seitz.com/~ross/envy24control/envy24control-control-limit-v2.… Testers would be greatly appreciated - especially those with cards other than the Delta44. -- Ross Vandegrift ross(a)willow.seitz.com A Pope has a Water Cannon.

[linux-audio-user] Audio Prototyping with Pure Data

by Levi Burton

>From the Inside Gamasutra newsletter: "Audio Prototyping with Pure Data" by Leonard Paul http://www.gamasutra.com/resource_guide/20030528/paul_01.shtml Interactive game audio requires combining content and code. Unfortunately, composers often have little control over how the code works and thus how the audio will sound in the final game. What's needed are tools that let the composer prototype the audio and show the programmer. One such tool is Pure Data, an open source program that is extensible, powerful, and, well, free. -- Levi Burton http://www.puresimplicity.net/~ldb/
