No I am not asking if audio over WIFI is a good idea :) But I thought some might be interested in this: https://www.kickstarter.com/projects/432967670/jack-the-wifi-guitar-cable I note that the actually latency as a number is not mentioned anywhere. There are this many times shorter than something else kinds of things, but not a number of ms from end to end. They suggest that they have "a total re-engineering of Wi-Fi to suit real time audio" yet at the same time they managed to "keep it compatible with existing devices meaning no changes to your PC or mobile device." BTW, Linux is not mentioned anywhere and neither is open (source or otherwise). However, I posted this because someone was asking about running a few more audio lines wirelessly and the common thought is that it can't be done with reasonable latency for monitoring. These people seem to think it can. They are talking compatible with a wide range of devices (android included) so the drivers are not being redone either. Auto-seeking low traffic wifi channels might be a part of it, but from what I have seen, scanning channels takes more time than anyone wants for a gap in audio. -- Len Ovens www.ovenwerks.net

new laptop configuration

by daniel gomez

Hello I am an Ubuntu 12.04 user in an 7yr old laptop. At this moment I urge a hardware improvement for my work which is: sound synthesis and processing controlled by external data via USB (kinect sensor and customa arduino based sensors) and WiFi (osc data). So i have to make an investment in a powerful laptop with the proper configuration for my needs which could be translated into: * very powerful processor for the dsp algorithms * 3+ usb ports (not hubs) so i can connect the external sensors and an external soundcard * a good wireless card that would not use any resources from the main processor * a video card that would not interfere with the main processor Although I think i know the basic needs, I can not name the manufacturers or models of the processor, board, video and wireless card that would make my system work the best. It would be of great help if you could help me choose these elements based on your positive experience on any of them and even more it would be great if you could recommend a specific commercial laptop that could have these features/elements already packed. Thanks for your help Daniel

Re: [LAU] LAU] Audio over WIFI

I guess most people think that tubes are as big as a bulb, actually some tubes are not much larger than a few transistors. While I don't remember the type designation of those tubes, I still remember the awesome audio sound quality.

Guitar strings and whammy bars

by Ralf Mardorf

The WiFi thread reminds me of another E. Guitar issue. In my experiences thick steel wounded strings produce the best sound, but thin nickel wounded strings better keep in tune when using old school whammy bars of the pre Floyd Rose area. Any reports about different experiences are welcome.

Korg microStation editor and Wine

by jonetsu＠teksavvy.com

Hello, I am trying the KORG microStation editor (Windows app with Wine on Linux Mint 17) and it has a connection with the synth and can change some params, so that looks not too bad. I have a question regarding those kinds of apps: it comes in one fix screen size. Is it possible somehow with Wine to have it full screen or larger at least ? Cheers.

Prog-rock album

by Ben Bell

Hi all, This month I released my first solo album. It's been five years in the making and recorded entirely with Ardour on Linux. Much like every other artist I don't really like labelling myself but reviews so far usually refer to it as Symphonic Prog like early Genesis, Yes and Camel. Preview sampler: http://music.benjamesbell.com/patchwork.html Now, I doubt this is going to raise much money, but as a thank you to the Linux and Ardour communities and developers I've generated to discount codes on Bandcamp. They're for a measly 5% off which is neither here nor there, *BUT* more to the point, I'll track the sales which used it and donate $2 for each one to the Ardour project at the start of January. The codes are "lad2014" for the digital version and "lad2014cd" for a physical CD, and can be entered during the bandcamp purchase process. The whole thing is also currently available for streaming if you're interested but don't want to pay: http://patchworkcacophony.bandcamp.com/ Best of wishes, Ben

Headphones

by Ralf Mardorf

Hi, I wonder what headphone has a better sound quality than the AKG K 240 DF and at the same time is that robust as this headphone. I got my AKG around 30 years ago, when it was the most used and IMO best studio headphone used in Germany. Within those decades there were several better sounding headphones used in professional studios here (but not in my home studio). All of them had a weak point. While you can play soccer with the AKG K 240 DF without damaging it, those headphones with a better sound quality, that still is relatively neutral, so that they can be used for recording in addition to monitors (not as a replacement for monitors ;), cause broken noise, once they fall down from face value. Is anybody aware about a modern headphone, that doesn't suffer from fragileness and anyway sounds better than a 30 years old studio headphone. IIRC I asked this a few years ago on this list or somewhere else. It's not Linux related, but at least related to audio production, so I guess it's a valid request for this list ;). I'm aware that the AKG K 240 DF and AKG K 240 still are used as headphones in studios for the folks that make the music, but usually it's not used by audio engineers any more. I can't pay for one of those modern headphones that are often used, but get broken by soft physical accidents. Regards, Ralf PS: This request is related to a question from an audio consumer from another Linux mailing list, asking me off-list, who wants to get a hint, what headphone is a good headphone. In my experiences reliability and best sound quality be in contrast. I don't know what headphone to recommend. I stay with the AKG K 240 DF, if it should get broken, I would buy the same headphone again, unless there's a headphone with a better sound quality and that is as stable as old headphones are. In my experiences the weakest point often is the headphone amp, not the headphone, so what headphone to recommend might also be related to the used gear.

LS compatible octoban samples

by F. Silvain

Hey hey everyone, I'm looking for samples of octobans[1] in Gigastudio/Gigasampler 2 or 3 or SFZ format. I have only found Epic Toms Ensemble[2], which is recorded in a large hall more suited to big film score type of music. Does anyone know of other drumkit libraries containing octobans? Thank you!

oscilloscope like wave display for jack?

by Ede Wolf

Happily I just realized, that after ~six years xoscope has it's new version announced a couple of hours ago, though not yet downloadable. But it now offers alsa support. That makes me wonder, wether there is a (lv2) plugin or jackified programm, that is capable of live displaying of audiowaves in an oscilloscope like fashion, even overlay two channels? I would not mind if it is limited to audio use/range at all. The Calf plugin suite has a nice analyzer, but it lacks this oscilloscope like display of waveforms. And since I only need it for audio, I would rather not buy a real one Sure, I now could always dedicate the onboard soundcard to xoscope, but maybe there is a more integrative way with the convenience of jack routing. And I might want to use onboard sound for smpte one day as well.
