[linux-audio-user] asoundrc for delta 66

by rob

Hi, Can someone show me an example asoundrc for the delta 66 I can't get mine working (everything works fine using oss emulation so I'm pretty sure this is were the problem lies at the moment mine looks like this. pcm.via { type hw card 0 } ctl.via { type hw card 0 } pcm.ice1712 { type hw card 1 } ctl.ice1712 { type hw card 1 } And if I try using it with aplay -D ice1712 it complains thusly: aplay: set_params:805: Sample format non available -- rob <mailingLists(a)pangolin.org.uk>

[linux-audio-user] recording problem with arecord / asound.conf issue?

by Akos Maroy

I'm still playing around and trying to get my Delta 1010LT to work, so I can record from the different input channels. I'm now simply trying to record using arecord, but I can't seem to record anything but silence. the specific problems I get: - I can't recrod from the hardware device as configured /etc/asound.conf I try: $ arecord -f cd -d 5 -D hw test.wav Recording WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo arecord: set_params:805: Sample format non available or $ arecord -f cd -d 5 -D ice1712 test.wav Recording WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo arecord: set_params:805: Sample format non available where $ cat /etc/asound.conf pcm.ice1712 { type hw card 0 } ctl.ice1712 { type hw card 0 } is the config that was hinted at the 1010LT ALSA driver installation page. BTW, $ arecord -l **** List of CAPTURE Hardware Devices **** card 0: 1010LT [M Audio Delta 1010LT], device 0: ICE1712 multi [ICE1712 multi] Subdevices: 1/1 Subdevice #0: subdevice #0 anyways, what does it mean by "Sample format non available", as the sound card supports this format? also, how do I list the available formats? - I can record from the 'default' device, but only silence I can succesfully run: $ arecord -f cd -d 5 -D default test.wav Recording WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo but, it only records silence, even though all my channels are _not_ muted, and I have input running in to the sound card at hardware inputs 3 and 4. I can see this from envy24control. I also experimented with default:0,1 ... 0,3 and default:1,0 ... 3,0, but the same occurs. what am I doing wrong? Akos

[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. Debian 3.0r0/Linux 2.4.18 TIA, Tim -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQE+2nYSsUUdIDHrdAURAuA1AJ92JjXQ3EE7wESOv6SRgfgcF5yppwCgoLEh exSzf48csmGri6QMoerd9Sw= =MEy8 -----END PGP SIGNATURE-----

[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 !
