OT? Downloaded youtube videos with subtitles

by Ivan K

I was very excited to find a video of the complete Tristan and Isolde on YouTube recently, complete with English subtitles. I used the youtube-dl utility to grab the video, but when I began playing the copy on my hard-drive with totem, to my horror, the English subtitles were not there! To repeat, the subtitles are on youtube.com but not in the .webm file that I downloaded with youtube-dl. Can someone coach me how to download a version with the English subtitles? Or are there subtitles in my downloaded version and totem is just not playing them? Thank you for your help. P.S. On the totem menu under View, there is a command called Subtitles but this prompts me for another file. Is there a subtitle file in addition to the video file that I need to download from youtube? Thanks again.

re Zoom R16

by reSet Sakrecoer

Hi all! I found this old discussion about the Zoom R16 in the archive of LAU. http://linuxaudio.org/mailarchive/lau/2012/3/14/188926 Strangely, in that archive there is a missing reply from Mr. Brett McCoy. (You can find the missing one a the bottom of this archive: http://linux-audio.4202.n7.nabble.com/Zoom-R16-td7748.html ) Mr. McCoy claims to have enabled the Zoom R8 (yes, there is quite a difference between r16 and r8) as a multi-input soundcard for ardour and also as a control surface in 12.04 64bits. There is no information as to which driver is being in use in his post. And searching the web only leads me to various WIP to get the R16 running on linux. My question is, has anyone got any news about this device and a possible drivers? Specifically to Mr. Brett McCoy: what driver did you use to make jack aware of your r8? Thank full for any hints, yours, -- Set Hallström AKA reSet Sakrecoer http://sakrecoer.com

Laptop soundcard

by Peter O'Doherty

Hi, My laptop (running ubuntu) has the following (audio) specs. I know it's probably subjective, but is this considered "good enough" for pro audio work or should I invest in an external sound card? (Or for that matter a better laptop?!) And if so, which soundcard is recommended? Thanks a lot, Peter Memory: 3.8 GiB Processor: Intel® Pentium(R) Dual CPU T3400 @ 2.16GHz × 2 00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03) Subsystem: Toshiba America Info Systems Device ff66 Flags: bus master, fast devsel, latency 0, IRQ 46 Memory at d6700000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel 00:1c.0 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 1 (rev 03) (prog-if 00 [Normal decode])

Which kernel do you use?

by Hermann Meyer

I've get a new (used) mobo, and played with the kernel version to use. So far I've tested all from 3.19.0-rc5 down to 3.4.104 Those, were rt-patches available I test as rt-kernel. Best results, I only get with the 3.4 series, all later kernels introduce Xruns here, sporadic, unrelated to the dsp load, even, when just jack is running. I build then all with the same configuration, play a bit with configurations deselect hyper-threading on the latest kernels, use threadedirqs, all to no avail. Only 3.4.xxx-rt kernel run absolute smooth. So, which kernels with witch configuration do you all use? System: Host: box Kernel: 3.4.105-rt129 x86_64 (64 bit gcc: 4.9.2) Desktop: Cinnamon 2.2.16 (Gtk 3.14.5) dm: lightdm Distro: siduction 14.1.0 Indian Summer - cinnamon - (201411230307) Machine: Mobo: Intel model: DG965MQ v: AAD37419-302 Bios: Intel v: MQ96510J.86A.1250.2006.1005.1532 date: 10/05/2006 CPU: Quad core Intel Core2 Quad Q6600 (-MCP-) cache: 4096 KB flags: (lm nx sse sse2 sse3 ssse3 vmx) bmips: 19200 clock speeds: min/max: 1596/2394 MHz 1: 2394 MHz 2: 2394 MHz 3: 2394 MHz 4: 2394 MHz Graphics: Card: NVIDIA GT216 [GeForce GT 220] bus-ID: 01:00.0 chip-ID: 10de:0a20 Display Server: X.Org 1.16.1.901 drivers: nouveau (unloaded: fbdev,vesa) Resolution: 1600x900(a)59.98hz GLX Renderer: Gallium 0.4 on NVA5 GLX Version: 3.0 Mesa 10.3.2 Direct Rendering: Yes Audio: Card-1 NVIDIA GT216 HDMI Audio Controller driver: snd_hda_intel bus-ID: 01:00.1 chip-ID: 10de:0be2 Card-2 Creative Labs SB Audigy driver: snd_emu10k1 port: 1000 bus-ID: 07:00.0 chip-ID: 1102:0004 Sound: Advanced Linux Sound Architecture v: 1.0.25 Drives: HDD Total Size: 164.7GB (26.4% used) ID-1: /dev/sda model: HDT722516DLA380 size: 164.7GB serial: VDK71CTCEBBN5X

Updated Ardour Tutorial

by Bruno Ruviaro

Hi all, Sorry for cross-posting. I just finished complete update to the old and good Ardour FLOSS Manual from 2009. All new screenshots (Ardour 3.5.403), and I updated the text wherever necessary: http://brunoruviaro.github.io/ardour3-floss-tutorial/ A few cosmetic changes still to be done, like removing the date from the header of every post, but overall it's ready to use. I'm using GitHub Pages, so it should be relatively easy for others to contribute, fork, and remix the manual. In the near future I plan to add a page explaining how to do so. Enjoy! Cheers, Bruno

HDSP Multiface: s2ram and resume?

by Peter P.

Hi, is anyone able to suspend a laptop computer with an active HDSP multiface soundcard (hdsp firmware loaded, hdspmixer running, jackd running)? My card is unusable when I resume the computer from a s2ram (S3) state. Hdspmixer is locked, jackd has died and I have to unplug and replug the ExpressCard, and restart hdspmixer and jack to get things back working. Does anyone have any similar or different experiences? This is on a Lenovo X220s with Debian testing and kernel 3.14-2-r best, Peter

[ANN] Qtractor 0.6.5 - The Fermion Ray beta is out!

by Rui Nuno Capela

Spread the word, Qtractor 0.6.5 (fermion ray beta) is out! Release highlights: * MIDI clip record/overdubbing (NEW) * Extended track multi-selection for mute/solo (NEW) * VST-shell sub-plugins support (NEW) * JACK transport start/stop resilience (FIX) And still, Qtractor is an audio/MIDI multi-track sequencer application written in C++ with the Qt4 framework. Target platform is Linux, where the Jack Audio Connection Kit (JACK) for audio and the Advanced Linux Sound Architecture (ALSA) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio. Website: http://qtractor.sourceforge.net Project page: http://sourceforge.net/projects/qtractor Downloads: http://sourceforge.net/projects/qtractor/files - source tarball: http://download.sourceforge.net/qtractor/qtractor-0.6.5.tar.gz - source package (openSUSE 13.2): http://download.sourceforge.net/qtractor/qtractor-0.6.5-15.rncbc.suse132.sr… - binary packages (openSUSE 13.2): http://download.sourceforge.net/qtractor/qtractor-0.6.5-15.rncbc.suse132.i5… http://download.sourceforge.net/qtractor/qtractor-0.6.5-15.rncbc.suse132.x8… - quick start guide & user manual (see also: the wiki): http://download.sourceforge.net/qtractor/qtractor-0.5.x-user-manual.pdf - wiki (help really wanted!): http://sourceforge.net/p/qtractor/wiki/ Weblog (upstream support): http://www.rncbc.org License: Qtractor is free, open-source software, distributed under the terms of the GNU General Public License (GPL) version 2 or later. Change-log: - Connections lines now drawn with anti-aliasing; connections splitter handles width is now reduced; the MIDI connections splitter pane sizes are now saved and restored properly. - Extended multi-selection is now featured on the track-list (main left-pane), primarily allowing for group mute/solo (and monitor) switching. - Track-list (left pane) header column widths are now saved and made persistent across application power cycle (double-click reverts to the old original default). - Minor fixes on the MIDI clip event list editor, also making sure the current event is visible on the piano-roll view. - As long to prevent asynchronous mistakes to JACK transport state changes, an internal slack-delay is now introduced after self-initiated transport commands (eg. start/stop). - The MIDI clip editor (aka. piano-roll) was missing to clear or reset the current selection when no shift/ctrl keyboard modifier is in effect. - VST-shell sub-plugins are now supported (as suggested by abique aka. Alexandre Bique, thanks). - MIDI clip record/overdubbing is now possible (Clip/Record on the main menu or File/Record from the MIDI clip editor. - Make sure some audio sample file encodings (eg. old Ogg Vorbis) does not head-start on audio peak generation.

Convert Hydrogen drumkits to sf2? hydro2sf2 doesn't work on Mint 17.1

by Artem Vakhitov

Hi, is it currently possible to convert Hydrogen drumkits to sf2? It doesn't work for me on Mint MATE 17.1. I downloaded the script and its associated .py files, checked for flac and sox being installed, and tried to use the script on a drumkit. It created an output file but it doesn't see to contain sounds. I received the following error in the console: ./hydroToSf2 3355606kit.h2drumkit bank name: 3355606kit designer: Artemio <http_//artemio.net> copyright: 2006, David Konsumer <david.konsumer(a)gmail.com> comment: Based on sounds from famous and classic beatboxes of 1970s and 1980s - Roland TR-606, TR-33 and Boss DR-55.
