[LAU] Ardour3: selecting the rest of a track

by jonetsu＠teksavvy.com

Hello, See attached. Is there a way to select everything after the reading point (the red line) ? There is a selection option (right-clicking on that track) that exactly sounds like it, but it acts on all tracks and, it does not select only after the reading point. I'd like to delete everything after that line - is this the way to do it ? - thanks.

[LAU] Ardour3: hiding/showing groups

by jonetsu＠teksavvy.com

Hello all, I've browsed the Ardour3 on-line manual 'Tracks and Bus groups' and although it mentions that operations can be made on hidden groups, it does not tell how to hide/show groups. At least not in there. Once a group of tracks is created, right-clicking on the group's 'tab' at the far left of the editor does not yield any option to hide it. I'd like to use that to cleanly make several sketches inside one session, each group of tracks being a sketch. How are groups hidden and then showed again ? - thanks.

The file is very easy to read and change. From reading the release notes on the developers page, it appears he expects it to auto save. I now have phasex starting with the light theme and a 9 point font. -- Len Ovens www.OvenWerks.net

[LAU] Ardour: does not create in specified directory

by jonetsu＠teksavvy.com

Hello, This is Ardour 1:2.8.14-1 (Linux Mint x86_64). I have now created three new sessions, and at first I thought I did somethign wrong, but now after creating another one I see that the specified directory I indicate for a new session in the opening dialog shown when Ardour starts was rightly chosen from the directory dialog box but still, the session was created in the home directory instead. A simple file-creation test in the specified directory is OK: % touch test % ll test -rw-rw-r-- 1 user user 0 avr 6 08:27 test % mkdir Test drwxrwxr-x 2 user user 4096 avr 6 08:29 Test/ Is this a bug in that version of Ardour or is there something else ? Creation of new sessions like this has always worked in the past. Thanks.

[LAU] ABX test invite

by Peder Hedlund

In view of the recent debate regarding the alledged "crappiness" of MP3 I thought it would be fun to see if the LAU society can tell lame (v3.99.4) MP3s from the original. Everyone is invited to download the testfiles from http://www.musikhuset.org/~peder/AxelF.zip , see if you can ABX them and post the result. There's one original WAV file and then 3 MP3s of various bitrates, which have all been converted back to WAV. The 165 MP3 was created using "-V4", the 124 "-V6" and the 108 "-V8 --resample 44.1" (since it wanted to make a 24 kHz file otherwise). - Peder

[LAU] Nano-Basket python version issue fixed

by Ralf Mardorf

Hi :) some days ago somebody from this list mentioned that Nano-Basket never worked. It always worked for me, but today I got an issue for my new Arch Linux. I could solve it, perhaps Roy or somebody with access to the git could update Nano-Basket, assumed it should be an issue for many distros. [rocketmouse@archlinux Nano-Basket]$ pacman -Q python python2 pygtk python2-pyalsa python 3.3.0-3 python2 2.7.3-4 pygtk 2.24.0-3 python2-pyalsa 1.0.26-2 [rocketmouse@archlinux Nano-Basket]$ diff nano_basket_main.py nano_basket_main.py.original 1c1 < #!/usr/bin/env python2 --- > #!/usr/bin/env python [rocketmouse@archlinux Nano-Basket]$ ./nano_basket_main.py.original Traceback (most recent call last): File "./nano_basket_main.py.original", line 23, in <module> from nano_basket_gui import * File "/usr/src/Nano-Basket/nano_basket_gui.py", line 23, in <module> import pygtk ImportError: No module named 'pygtk' [rocketmouse@archlinux Nano-Basket]$ ./nano_basket_main.py and the GUI started :), until now not tested if it works ;).

[LAU] Interacting with external audio/MIDI devices on Linux

by Ralf Mardorf

Don't know if it ever was announced at LAU, regarding to the blogger's name it's likely that it already was posted, however: http://prokoudine.info/blog/2010/10/interacting-with-external-audiomidi-dev…

[LAU] What is the best MP3 encoder?

by Jostein Chr. Andersen

Hi, I do have what I consider as a big problem with MP3 encoding, and that is artifacts and degenerated sound quality. End results are things like stronger esses, more "noise" (IE. something like schhhhhh upper overtones on disted guitars) and a loss of clarity. The thing is that a finished 320 kbps MP3 should not sound (significant) different than an original wave file IMO. Note that this artifacts are usually quite subtle, but very audible for the person(s) that recorded it and the mixer. I usually do mixes in 24/44.1 and I'm using dithering when exporting to a 16-bit stereo file. The artifacts, especially stronger esses are more audible without dithering and it should really not matter. I'm using Mixbus (Ardour) for exporting the wav files to 16-bit waves and Audacity for converting the file to a MP3. If I upload a lossless file to soundcloud, then the same problem comes there when Soundcloud converts it to it's player. Unfortunately, I don't have a raw 24/44.1 file and a MP3 I legally can post right now. But I hope that someone have suggestions about how to make the best possible MP3 files from a wave file. :-) Thanks, Jostein

They have a very live sound, I think because there is a very thin coat of finish. I have both classical and folk instruments. I have a more expensive Yamaha 12 string that sounds no better than the $100 El Degas plywood model I had when I was 16.

Re: [LAU] Any HW and SW based backing-band solutions?

by Ralf Mardorf

"Impedances Mic in: 3.4 kilohms Channel insert return: 5 kilohms All other inputs: 20 kilohms or greater" - http://www.mackie.com/products/802vlz3/pdf/802VLZ3_OM.pdf "Nominal Output Level PHONES/LINE OUT jack: -14 dBu Output Impedance PHONES/LINE OUT jack: 22 ohms" - http://lib.roland.co.jp/support/en/manuals/res/62121932/BR-80_e04_W.pdf This is as wanted, a low impedance output -> high impedance input, since the mixer and the BR-40 do work, it must be the cable. Unlikely that the cable is to long, but many jacks tend not to fit to many sockets. Even if it should be the correct cable and even if it's not broken, it could be, that the jack must not go completely plugged in. I experienced often that 1/4 jacks have different construction forms, so that they don't fit to each other.
