I told some friends to come over tomorrow to make a recording ... and, of course, I can't get things to work on the computer. Hope someone can set me straight. I'm using pulse and audacity ... yeah, I know someone will tell me that will never work, but it's worked just fine in the past. So, lets continue :) I'm using a Audiobox USB interface with a single mic. I have tried different mics and cables, so I'm pretty sure that's not the problem. In the pavucontrol program the audiobox shows and I select Analog Stereo Output + Digital Stereo (IEC958) Input Now, when I bring up audacity I have 3 inputs available. Well, this time ... sometimes I have a list as long as my arm. But, for now lets use the short list: HDA Intel ... Pulse Default Both Pulse and Default appear to work as recording devices. Funny, though is that at other times I've gotten a raft of HDA lines, USB lines, etc. Doesn't seem to make sense to me. First off, lets test playback of a track in audacity to phones. Great ... perfect. Audacity (and everything else on the system)plays though the device into the phones. I'm happy. Now, I will record. I get the waveform. I speak into the mic ... and then I play back ... and it is just awful, scratchy crap. So, if you've read this far my problem is that I am getting crappy, very crappy, recording quality with the audiobox interface and audacity. Suggestions? I should add this output as well: arecord -l **** List of CAPTURE Hardware Devices **** card 0: USB [AudioBox USB], device 0: USB Audio [USB Audio] Subdevices: 0/1 Subdevice #0: subdevice #0 card 2: PCH [HDA Intel PCH], device 0: ALC887-VD Analog [ALC887-VD Analog] Subdevices: 0/1 Subdevice #0: subdevice #0 card 2: PCH [HDA Intel PCH], device 2: ALC887-VD Alt Analog [ALC887-VD Alt Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 4: U0x46d0x802 [USB Device 0x46d:0x802], device 0: USB Audio [USB Audio] Subdevices: 0/1 Subdevice #0: subdevice #0 Thanks to all. -- **** Listen to my FREE CD at http://www.mellowood.ca/music/cedars **** Bob van der Poel ** Wynndel, British Columbia, CANADA ** EMAIL: bob(a)mellowood.ca WWW: http://www.mellowood.ca

[Off topic] DIY Theremin

by Dominique Michel

I was very busy for a few months with the transformation of an old vacuum tube radio into a Theremin. The result is really amazing and very fun to play. It is documented here: https://github.com/domichel/black_star_theremin I post it here because I think (wrongly or not...) than some of you may be interested by such a vacuum tubes project. The audio part makes also an outstanding guitar amp. Cheers and Happy New Year to all, Dominique -- If you have a problem and you are not doing anything to fix it, you are at the heart of the problem.

for sale: "vintage" RME interfaces

by Paul Davis

It's bonanza time for anyone interested in some RME gear for use with "vintage" computers (defined as ones with a PCI bus. Yes, PCI. Not PCI(x) or PCI(e) or other later variant. Just PCI). What's available: RME Hammerfall 9652 3x ADAT in/out Daughterboard for word clock Breakout cable for 9-pin Sony protocol & S/PDIF Little-endian ROM chip installed, Big-endian enclosed RME HDSP9652 3x ADAT in/out (missing MIDI I/O breakout cable) RME Digiface half-height PCI card External breakout box, 3x ADAT in/out, S/PDIF, MIDI, word clock (nice long) Cable to connect Bonus: PCMCIA card for digiface, with required cable 2 x ADAT cables I fully understand that these are now all legacy products, but they also all continue to function at the highest levels. If you have the right bus, and want/need the I/O configurations that these devices offer, you still cannot get a better device, even 20 years (in some cases) after their original release. I'm not looking to make money on these devices, but I don't want to give them away either. I'd prefer to ship them all as a single package (anywhere in the world). So, make me an offer. All were working the last time I used them; if any are not working when you receive them, I'll refund you an appropriate part of whatever you paid. I'm listing them here first because of the importance of this crowd and these interfaces to what I've been doing for the last 20 years. Make me an offer. For history buffs, the RME Hammerfall 9652 was the interface that made me write Ardour.

Still trying to record

by Bob van der Poel

Just tried a 2nd test method: "pasuspender audacity" Now I get "proper" input/output listing in audacity. The recording quality is worse or no better. -- **** Listen to my FREE CD at http://www.mellowood.ca/music/cedars **** Bob van der Poel ** Wynndel, British Columbia, CANADA ** EMAIL: bob(a)mellowood.ca WWW: http://www.mellowood.ca

Looking for voice recording suggestions

by hollundertee＠gmx.net

Hi there, I'm currently taking part in a game jam and I'll have to do a whole lot of voice recordings tomorrow. I have barely any experience with that. I do have a laptop, USB audio interface, mic, stand and a bunch of questions. 1) Room: Besides corridors and such I have access to a roughly 2x10 m room or a bigger room, I guess 10x20 m. I guess go for the bigger one? They are both rather empty, safe for tables and chairs. 2) Recording software? Ardour, something simpler? 3) Post processing, normalization of some sort. I'll have at least four total amateur voice actors and all in all hundreds of lines. 4) What did I forget? Thank you in advance for any suggestions. Best regards, Philipp

Re: [LAU] Linux-audio-user Digest, Vol 142, Issue 14

by Open Source Music Production House

Mmm ... i have an old machine here like a pent up 75mhz or such it has my old awe 32 as a soundcard just needs some ram .... kind of like that idea having a separate recording box with RME cards. No idea what that should cost though but willing to sign in blood ;) they would be in good hands and treated like historic valuables in a working museum. No im not begging no... :) Have a great weekend all On Fri, Dec 14, 2018, 9:25 PM <linux-audio-user-request(a)lists.linuxaudio.org wrote: > Send Linux-audio-user mailing list submissions to > linux-audio-user(a)lists.linuxaudio.org > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.linuxaudio.org/listinfo/linux-audio-user > or, via email, send a message with subject or body 'help' to > linux-audio-user-request(a)lists.linuxaudio.org > > You can reach the person managing the list at > linux-audio-user-owner(a)lists.linuxaudio.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Linux-audio-user digest..." > > > Today's Topics: > > 1. for sale: "vintage" RME interfaces (Paul Davis) > > > ---------------------------------------------------------------------- > > Message: 1 > Date: Thu, 13 Dec 2018 17:15:16 -0500 > From: Paul Davis <paul(a)linuxaudiosystems.com> > To: linux-audio-user <linux-audio-user(a)lists.linuxaudio.org> > Subject: [LAU] for sale: "vintage" RME interfaces > Message-ID: > <CAFa_cKn0vgVCWvX300MTAFE7= > ytnSwU0wmdOo797rMkHkhO9kA(a)mail.gmail.com> > Content-Type: text/plain; charset="utf-8" > > It's bonanza time for anyone interested in some RME gear for use with > "vintage" computers (defined as ones with a PCI bus.

Problems delivering mail to certain mail providers

by David Runge

Hey all, some of you (e.g. users of free.fr [1]) are currently seeing problems with the LAD/LAU mailing lists. It seems to be triggered by those mail servers still trying to negotiate handshakes using obsolete and unsafe SSLv3 ciphers. Several of you might have received an unsubscription notice from the mailing list. Please note, that this is not done out of malice, but because after several connection drops, mailman will automatically kick subscribers off the list - which is usually good for non-existing mail hosts or mail addresses. However, in this particular instance I think it is due to us not allowing those SSLv3 ciphers anymore (most mail providers actually don't) and have not done so since the beginning of the year (configuration-wise nothing has changed significantly in quite some time either, which is even more pointing in an outwards direction). The only solution to this - to my opinion - is to fix your mail server setup (if you operate your own mail server) or ask your mail provider to fix theirs (if you are using someone else's services). You can validate the functionality of your TLS setup [2] before and/or afterwards. If both are non-viable options for you, I suggest switching to a mail provider, that has a more well-maintained and configured mail server setup (as we're able to deliver to other mail providers just fine). Best, David [1] https://ssl-tools.net/mailservers/free.fr [2] https://ssl-tools.net/mailservers/ -- https://sleepmap.de

[ANN] Vee One Suite 0.9.4 - A Late Autumn'18 Release

by Rui Nuno Capela

Greetings! The 'Vee One Suite' of so called 'old-school' software instruments, synthv1 [1] as a polyphonic subtractive synthesizer, samplv1 [2] a polyphonic sampler synthesizer, drumkv1 [3] as yet another drum-kit sampler and padthv1 [4] as a polyphonic additive synthesizer, are all being released for the late in Autumn'18. All still available in dual format: - a pure stand-alone JACK client with JACK-session [5], NSM (Non Session management [6]) and both JACK MIDI and ALSA MIDI [7] input support; - a LV2 instrument plug-in [8]. The changes for this special season are the following: - Make sure all LV2 state sample file references are resolved to their original and canonical file-paths (not symlinks). (applies to samplv1 [2] and drumkv1 [3] only) - Fixed a severe bug on saving the LV2 plug-in state: the sample file reference was being saved with the wrong name identifier and thus gone missing on every session or state reload thereafter.(applies to samplv1 [2] only) - Sample waveform drawing is a bit more keen to precision. - Old deprecated Qt4 build support is no more. - Normalized wavetable oscillator phasors. - Added missing include <unistd.h> to shut up some stricter compilers from build failures. The 'Vee One Suite' are free, open-source Linux Audio [10] software, distributed under the terms of the GNU General Public License (GPL) [11] version 2 or later.

Acid December 2018

by Set Hallstrom

Hi all, As happens every year with very special winters, the thousand year old tradition of Acid December takes places this year! What is special with this years winter you may ask: there is Acid December! Some of you contributed delicious acid in 2015 and perhaps you want to do it again? For those of you new to this, it is very simple: every day during December a track is released on acid.datapop.se Depending on the amount of contributions, this can last long into the months after. The music should be acid (https://en.wikipedia.org/wiki/Acid_house https://en.wikipedia.org/wiki/Acid_techno ). You may include a picture, a text and a link to wherever on the interwebs you'd want to be found. Or stay anonymous. Obviously your tracks need to be licensed in a way that permits being freely distributed in a non-commercial context. Please submit reasonably sized mp3/ogg files. Looking forward to listen! Yours, -- Set Sakrecoer
