Re: [LAU] Puredyne 9.11 (Carrot and Coriander+) - new release of realtime audio+video distro

I've been using Debian in the past, compiling kernels, JACK, ALSA, etc,etc from source, but recently switched to Gentoo. Then other things got in the way of setting up audio production software so have nothing running. I'm kinda sick of building stuff from source at the moment so (64bit) Pure Dyne looked like the solution to that, but without ardour2, it's just not. Disappointing. And why punish us with grub2? I had a hellish time trying to configure it a couple of months ago and gave up and installed legacy grub. james.

Hardware suggestions

by rosea.grammostola

Hi, I'm searching for a new second hand PC for my friend, around the 350 euro. Is it smart to buy this stuff as a whole or in components? It looks like 64bits has some advantages... What are good motherboards and what is good CPU? Thanks in advance, \r

StretchPlayer 0.500 - Audio player with time stretch and pitch shifting

by Gabriel M. Beddingfield

I am pleased to release StrechPlayer 0.500, a time-stretching, pitch-shifting audio file player. It is powered by librubberband, and also features an A/B repeat. This is the first release of StretchPlayer. LINKS ----- Home Page: http://www.teuton.org/~gabriel/stretchplayer/ Tarball: http://www.teuton.org/~gabriel/stretchplayer/stretchplayer-0.500.tar.bz2 Git: http://gitorious.org/stretchplayer git://gitorious.org/stretchplayer/stretchplayer.git USING THE PROGRAM ----------------- You will need at least a 1200 MHz processor to use this program. It also requires the following libraries: * Qt >= 4.4 http://qt.nokia.com * librubberband http://www.breakfastquay.com/rubberband/ * libsndfile http://www.mega-nerd.com/libsndfile/ * JACK http://jackaudio.org/ * CMake http://www.cmake.org/ After building, run the program like this: $ stretchplayer The GUI is pretty self-explanatory, and if you hover over the controls a tool-tip should appear. The GUI also has several keyboard accelerators. ACKNOWLEDGEMENTS ---------------- My sincere thanks to Chris Cannam for publishing the RubberBand library. I've wanted this thing since I was in High School. :-) Peace, Gabriel M. Beddingfield

M-Audio Audiophile 2496 on modern Ubuntu

by Joshua Boyd

Does anyone have a M-Audio 2496 card working in a recent Ubuntu distribution? What I'm finding is that it finds the card, but in the Gnome sound prefferences it only has profiles for the Digital ins and outs. If I use aplay -L, this is the output: front:CARD=M2496,DEV=0 M Audio Audiophile 24/96, ICE1712 multi Front speakers surround40:CARD=M2496,DEV=0 M Audio Audiophile 24/96, ICE1712 multi 4.0 Surround output to Front and Rear speakers surround41:CARD=M2496,DEV=0 M Audio Audiophile 24/96, ICE1712 multi 4.1 Surround output to Front, Rear and Subwoofer speakers surround50:CARD=M2496,DEV=0 M Audio Audiophile 24/96, ICE1712 multi 5.0 Surround output to Front, Center and Rear speakers surround51:CARD=M2496,DEV=0 M Audio Audiophile 24/96, ICE1712 multi 5.1 Surround output to Front, Center, Rear and Subwoofer speakers iec958:CARD=M2496,DEV=0 M Audio Audiophile 24/96, ICE1712 multi IEC958 (S/PDIF) Digital Audio Output This is what I see both on 10.04 i386 and on 9.10 AMD64. I know this card was previously working correctly under 6.06-7.something, and then I had it working happily in a mac for awhile before trying to move it to my new linux audio project machine. I really hope I can get it going happily.

How to handle large amount of pdf files (music sheets) for collaborative usage

by Nils Hammerfest

Hi List, This is a question what is the best way to make a lage amount of pdf files (hundreds of GB, more to come) and make them available for a Local Area Network of users to print and edit them. Make them searchable and get the file easily and send them per mail to print. There is currently a Windows solution including completly unfree tools so that not every computer can even do the work we are supposed to do because of license restrictions (at least its all legal). The current windows-based database is slow in access and has a heavy lag to snyc files, sometimes even hours. I don't have access to the servers so I can't check whats going on, but I want to know if there isn't a Linux way :) Where I work we prepare lots of notation for print and finally print them. There are sadly no source files: We get generated pdf files from various software from all OS and we produce scans of existing material. There are few meta information like Composer, Title and a serial number. Actual Questions: 1) What Database/Way and Frontend would you use to handle pdf files? (Filesizes per file >200 kb <200 MB, Multiple files per project/musical piece ) 2) Do you know any free PDF editor besides "PDFEdit" (which seemed fine from screenshots and descriptions, but first tries were not successful) Always this unfree binary crap, Nils

[problem] no sound from one channel, VIA Technologies Inc. VT1720/24

by Marcos Germán Guglielmetti

Hi I have this PCI soundcard (from "Encore" manufacturer) and I am using debian lenny lspci | grep audio 01:09.0 Multimedia audio controller: VIA Technologies Inc. VT1720/24 [Envy24PT/HT] PCI Multi-Channel Audio Controller (rev 01) I cant get sound of the 2 channels using neither an old 2.6.18 kernel or a new 2.6.32 from Debian or a 2.6.29 from Musix. There is no problem with the physical output jacks: all headphones play only one channel. Also i tried with all the mixers: alsamixer, gamix, gnome-alsamixer, kmix, etc. enabling and disabling all the things and it does not work well. Any clue? uname -a Linux musix 2.6.32-trunk-686 #1 SMP Sun Jan 10 06:32:16 UTC 2010 i686 GNU/Linux Regards, -- Marcos Guglielmetti www.musix.org.ar www.ovejafm.com

[Music] Another, very short, prog instrumental

by Q

So here I am once more... Hello everyone. First of all, advance apologies to people awaiting the next instalment of Lovatnet, which I posted in October – this isn’t it. Among other things, since that time I’ve been busy on a big project, collaborating with a friend – that will make an appearance at some point far in the future as there is much work still to do and work is currently on hold. To keep myself busy in the meantime, I decided to pick up an idea from about 12 years ago, which was thrown together (it doesn’t deserve the word written) on my old four-track with electric piano, bass, guitar and the drum machine on a Hammond organ (so obviously not a proper Hammond, sadly. I’ve had vague ideas in the past few year about doing something with the piece, but never got anywhere with it. I decided in December to try, once and for all, to get somewhere with developing it and it seems that in the past few months the time was right; the writing then turned into recording and mixing and so, three months later, here we are. I’m not even sure the original idea really deserved so much effort throwing at it, but it’s been fun progging it up a bit and hopefully turning it into something a little more interesting – it’s good to recycle :-) It’s a short piece of instrumental symphonic progressive rock, the opening section of what will be a longer piece – this part is finished and I have a vague idea what the next section will be like, I just need to put the work into writing and developing it. And after that, well, who knows… but as always with me, don’t hold your breath. I don’t think the mix could have been what it is without a few recently discovered effects that came to be of critical importance (thanks to Dave Phillips for the heads-up in LJ!), notably the EQ10Q and the Calf and Invada compressors especially, without which some desired sounds would have been impossible to achieve. It’s turned into a bit of a monster really: if I counted correctly late last night, the Ardour session has 50 active tracks and 28 busses, it takes a good minute or so to load – even the mixing has become overblown and pretentious, excellent! :-P It’s been an enjoyable pass-time and an interesting and useful learning process though. As always, general thanks to all Linux devs, but particular gratitude to those involved with Ardour, Hydrogen, Linuxsampler, Wine and all the LADSPA and LV2 plugins. Full, geeky details of instrumentation and equipment etc are below for anyone who might be interested. I’ve done no post-processing/mastering beyond limiting to raise the overall level a bit. I give you Beyond Triple Point (part 1): FLAC (14.6 MB): www.quirq.ukfsn.org/Quirq_Beyond-Triple-Point_Part1_16-03-10.flac OGG-10 (7.4 MB): www.quirq.ukfsn.org/Quirq_Beyond-Triple-Point_Part1_16-03-10.ogg And much as it pains me... MP3 (6.2 MB): www.quirq.ukfsn.org/Quirq_Beyond-Triple-Point_Part1_16-03-10.mp3 Anyway, I hope you might perhaps enjoy it, short as it is. Q CAUTION!

joining alsa devices (fasttrack pro)

by Dan S

Hi - I have an M-Audio FastTrack Pro with 2 ins and 4 outs, which shows up as two devices (hw:1,0 and hw:1,1) splitting the outputs. In trying to merge them back together to get 4-channel output, I used the .asoundrc given here: http://alsa.opensrc.org/index.php/.asoundrc#Joining_devices_to_make_multich… Now I'm unsure how to specify that this multi device should be used. alsa -l shows me: default:CARD=Intel HDA Intel, ALC662 rev1 Analog Default Audio Device front:CARD=Intel,DEV=0 HDA Intel, ALC662 rev1 Analog Front speakers surround40:CARD=Intel,DEV=0 HDA Intel, ALC662 rev1 Analog 4.0 Surround output to Front and Rear speakers surround41:CARD=Intel,DEV=0 HDA Intel, ALC662 rev1 Analog 4.1 Surround output to Front, Rear and Subwoofer speakers surround50:CARD=Intel,DEV=0 HDA Intel, ALC662 rev1 Analog 5.0 Surround output to Front, Center and Rear speakers surround51:CARD=Intel,DEV=0 HDA Intel, ALC662 rev1 Analog 5.1 Surround output to Front, Center, Rear and Subwoofer speakers surround71:CARD=Intel,DEV=0 HDA Intel, ALC662 rev1 Analog 7.1 Surround output to Front, Center, Side, Rear and Woofer speakers null Discard all samples (playback) or generate zero samples (capture) ttable4:CARD=Intel,DEV=0 HDA Intel, ALC662 rev1 Analog 4 channel multi route default:CARD=Pro FastTrack Pro, USB Audio Default Audio Device front:CARD=Pro,DEV=0 FastTrack Pro, USB Audio Front speakers surround40:CARD=Pro,DEV=0 FastTrack Pro, USB Audio 4.0 Surround output to Front and Rear speakers surround41:CARD=Pro,DEV=0 FastTrack Pro, USB Audio 4.1 Surround output to Front, Rear and Subwoofer speakers surround50:CARD=Pro,DEV=0 FastTrack Pro, USB Audio 5.0 Surround output to Front, Center and Rear speakers surround51:CARD=Pro,DEV=0 FastTrack Pro, USB Audio 5.1 Surround output to Front, Center, Rear and Subwoofer speakers surround71:CARD=Pro,DEV=0 FastTrack Pro, USB Audio 7.1 Surround output to Front, Center, Side, Rear and Woofer speakers iec958:CARD=Pro,DEV=0 FastTrack Pro, USB Audio IEC958 (S/PDIF) Digital Audio Output ttable4:CARD=Pro,DEV=0 FastTrack Pro, USB Audio 4 channel multi route ttable4:CARD=Pro,DEV=1 FastTrack Pro, USB Audio #1 4 channel multi route While "aplay somesound.wav" or "aplay -d default somesound.wav" is fine to play through the internal soundcard, I haven't figured out what arguments to use to play the sound through the aggregated device (one of the ttable4 entries in the above list). In fact "aplay -d hw1:0 somesound.wav" also simply plays through the internal soundcard so I must be doing something wrong. Any suggestions? Thanks Dan -- http://www.mcld.co.uk
