[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

[LAU] 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

[LAU] 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.

[LAU] 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

[LAU] 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.

[LAU] Renoise Redux

by Kaza Kore

Sorry for posting on something non-FOSS but there has been enough talk on Bitwig over the years and that piece of software costs five times as much for me to not feel guilty... Anyway I noticed Renoise has brought out Redux fairly recently. Thought I may have seen some chatter about it already as there is at least one Renoise user on the list and sure some of you used trackers back in their hayday. Unfortunately Linux VST only but still maybe of interest to some of you... http://www.renoise.com/products/redux

In general, the big thing with a digital mixer is lots of mic pre. You have 16. The motu 8M has only 8 but is a class compliant USB2 IF and can be controled by OSC (I downloaded the OSC spec out of interest) or by browser. More pres could be added, but at the expense of lugging more stuff around. I agree that for your purposes The digital mixer is probably better. Certainly the remote gui for linux has got to be better than a browser interface. I have tried the linux mixer gui for the xr18 and it is better than any of the browser gui I have tried. The android version is not as nice :P -- Len Ovens www.ovenwerks.net

[LAU] [ANN] setBfree v0.8

by Robin Gareus

G'day. setBfree is a MIDI-controlled, software synthesizer designed to imitate the sound and properties of the electromechanical organs and sound modification devices that brought world-wide fame to the names and products of Laurens Hammond and Don Leslie. http://setbfree.org https://github.com/pantherb/setBfree It's been over 18 months since the last release and setBfree just reached another major milestone: It now features a proper GUI that allows to configure various aspects that have previously only been accessible via text config files (the config and program file-format itself has not changed). The GUI is available as LV2 and standalone jack application and the old tcl/tk prototype UI was removed for good. visit https://vimeo.com/130633814 for a demo. The 2nd big change was reworking the Leslie: The horn now spins counter-clockwise (same as the real thing) and we finally managed to track down the aliasing noise that was audible during acceleration and deceleration. Since various users play guitar and some even cello through it, an animated LV2 GUI was added for the whirl-speaker emulation and it has also been made available as standalone jack client. Advanced settings such as microphone angle, position, horn radius, etc are now also exposed (both for the organ as well as the LV2). The UI looks like https://raw.githubusercontent.com/pantherb/setBfree/master/doc/b_whirl.png Other notable changes include new addition of presets for Kurzweil and Korg CX3 and updates to portability (ARM-CPU/RPi, Windows + OSX versions). The full list of over 300 changes since 0.7.5 is available as git log. Binaries for Intel platform, GNU/Linux, OSX and Windows are available from https://github.com/pantherb/setBfree/releases/latest though for Linux most distros will pick this up as usual. Many thanks to Axel 'the C.L.A.' Müller and Jean-Luc Nest who provided valuable feedback and inspiring music during the development cycle. happy playing, robin + will
