[linux-audio-user] Sub-harmonic generator? (LADSPA or VST)

by Tim Howard

Hello, Does anyone know of a good plugin that will generate subharmonics? I would like to put a little more low frequency "oomph" into my bass track. Preferrable LADSPA, but VST would work, too. Thanks for any help! -TimH

NAMA, non-distructive?

by Hart Larry

Thank you MR Hawaii, I forgot I had installed that, but looking in its man-page, makes references to non-distructive editing. If I understand the concept, I would think editing out portions of sound would certainly be destroying an orriginal. Meanwhil, if I run nana -t and a file name, I get the following error: Found config file: /home/chime/.namarc YAML::Tiny found bad indenting in line ' consumer:' at /usr/share/perl5/Audio/Nama/Assign.pm line 283. So please, how do I fix this-and-would NAMA be an interactive editor? Thanks in advance Hart

Alternative FluidSynth GUI?

by Dan Capp

Research tells me that QSynth seems to be the only currently available/usable GUI for FluidSynth, but I get big xruns whenever I try and use it. FluidSynth itself doesn't cause me problems (I know because I'm able to use the FluidSynth-DSSI plugin fine in Rosegarden etc). The problem is that I want to use FluidSynth with Ardour3, but Ardour3 doesn't support DSSI plugins yet. So the only solution I have is to find a standalone interface for FluidSynth and then to link up using Jack. I looked at the old GUI 'FluidGUI' but it seems to be so old that it won't properly install on recent versions of Ubuntu. So does anyone know of: 1) A GUI for FluidSynth other than QSynth and FluidGUI?... or 2) An application other than the above 2 which would allow me to load soundfonts? Thanks in advance. - Dan

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

New hardware setup for recording (not same as existing threads)

by Martin Cracauer

I am also looking to have a conversation about recording hardware, but not quite the same as the PCI one. Short story: If I wanted to have a combination of two separate devices, analog->ADAT unit and ADAT->Linux@computer, what would I buy? Long story: The way that I did quality recordings so far: - use a quality preamp from mic to S/PDIF optical - use a USB soundcard with (under Linux) working S/PDIF in - jackd of course - depending on hardware there might be a separate piece in front that converts symmetric microphone level to line out, but right now my first thing does both mic level and line level well I really like how this is separating out the [analog part, A/D converter] and the [thing that needs a Linux driver]. Now I can change one or the other and don't get utter breakdown on software changes. I have hardware pieces for which this works great... ish except for some USB unreliability. Now, the careful observer will notice that this is limited to 2 channels due to S/PDIF. While I could have more USB soundcards that does not satisfy synchonization since the stupid things with S/PDIF don't take world clocks. My attempts to link multiple jackds have been, well I think everybody here knows that this exactly working well. So I want to get the concept of separating this out further. Now I need: - analog part is a few line in or mic level inputs to ADAT - a "soundcard" that takes binary ADAT and gives me Linux-able input. Ideally I would like this to be 24 bit capable (I don't need > 48 MHz but I'd like > 16 bit) - once there I could add more sync ADAT takes a world clock I wonder whether somebody has recommendations for these two parts. Digital part with great Linux support, and what do I use for analog to ADAT? My computers still have native PCI, but... well to be honest PCI sucks, USB sucks, Firewire is old. Is anything Thunderbolt out yet that does ADAT to Thunderbolt with open source Linux drivers? Haha, very funny. Can we make one? Sorry for the long post. I hope the concept makes sense. I really like this more modular setup that allows you to toss one thing at a time and don't sit there with nothing on changes.

jalv.select

by Hermann Meyer

Some of you knows my little python script which act as a GUI for jalv, to select and run LV2 plugins with a selectable jalv interpreter. Now, I realize that debian didn't include the lilv python wrapper any more, and the script wont run without it. So I decide to port this script to C++ / gtkmm. It's now a regular desktop application with makefile, menu-entry and such. Get it here: https://github.com/brummer10/jalv_select Features: select jalv interpreter from combo box, select LV2 plugin from list, search plugins by regex, reload lilv world to catch new installed plugins, simple and lightweight in old unix style, load plugin on single click.

Searching for audio interface with software-controlled mic gain

by Thomas Janu

Hi List, for a project at work (nothing to do with music, sadly, but at least audio) I'm looking for an audio interface that supports at least 16bit/48kHz (24bit/96kHz would be even better, we're potentially looking for rather high frequency signals...) for two mics that need phantom power and where the preamp gain can be controlled remotely by software, as this will be used as follows: The whole setup will be mounted at a remote location inside a larger machinery for audio surveillance of said machinery (fault detection etc.). The larger machinery of course may not be running while opened to install our setup, thus setting the gain has to be done remotely. The PC in this setup has an x86_64 CPU running Ubuntu 12.04 LTS, but the case is too small for PCI(e) solutions, doesn't have firewire, so the only option is USB. For our current setup we have a Focusrite Scarlett 2i2 here, but there's no way to set the mic gain via software :-/ Researching so far led me to the RME Babyface that is said to be supported when in class compliant mode - but you seem to need to hold down buttons while turning it on, which is a problem as we can't open up the larger machinery every time the hardware needs to be restarted. Is anyone here aware of something we could use here? Thanks in advance, Thomas

Re: [LAU] An Easier mp3Editor?

by Karen Lewellen

Hi Larry, i actually thought most mp3 editors worked as you described...but I do not normally edit mp3 files or not this way. does not audacity have a command line component to it?
