AVB on linux: drivers?

by Bearcat Şándor

With regards to Moshe Werner's post on the Motu 1248 working on Linux, it seems that AVB (AES67) works on Linux as well. This is a dream come frue for me. What i'm confused by, is where the drivers are. I can't find the drivers in the linux kernel or on alsa, but maybe my Googlefu is weak today. I do note that the Digigram LX-IP Digigram LX-IP RAVENNA, 128 in/out RAVENNA/AES67, PCIe Sound ... <https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=4&ved=0ahUKEw…> suppots Linux but i don't know wether it's a binary driver on an open standard, or a specialized driver for that card. In short, where does one get Ravenna drivers? Thanks, -- Bearcat M. Şándor, CEO Feline Soul Systems LLC Voice: 872.CAT.SOUL (872.228.7685) Fax: 406.235.7070

Looking for digital mixer for church use

by Bill Purvis

This is not really a Linux audio question, but I'm sure some of you will have suggestions for the following: I'm currently looking into providing the Audio system for our new church building which is expected to be handed over soon. At present I'm using a Soundcraft Ui16 digital mixer, but that only has 12 real inputs. I'm thinking ahead and would like something similar but with twice (or more) as many inputs. Any suggestions welcomed, Many thanks Bill -- +----------------------------------------+ | Bill Purvis | | email: bill(a)billp.org | +----------------------------------------+

Motu 1248 - Full success

by Moshe Werner

Hi Folks, after a long period of being distracted from doing sound work I'm getting back into business. I needed a solid solution for Audio Interface, so I started researching. I must say that from my perspective a lot has happened in the past three four years. More class compliant interfaces enter the market and the horizon widens regarding hardware in Linux. I came across the new Motu AVB devices and could'nt believe that they would be the solution to my hardware problems. The point is, my old studio and travelling interfaces are RME HDSP9652 and TC Impact twin, respectively. The RME always just worked. Pretty low latencies and with the right configuration zero xruns. The TC has a little bit higher latency but also pretty solid. But... they are old interfaces and the time will shortly come when I will not be able to buy a new PC/laptop with PCI or Firwire ports. So I looked for other options... Rme new stuff is mostly class compliant but has proprietary drivers and that means no control over certain features. So I got a pretty good deal on a Motu 1248 and went for it. Here are my first impressions from half a day of testing. First and foremost, the interface just works! Out of the box. I plugged it in configured Jack and got sound. Great... and non trivial for Linux. After a bit of fiddling around with my Network settings I got the control software to work, and I must say it's just amazing to have a piece of equipment that I can fully use under Linux. There is a full featured mixer in the DSP that's also a nice addition, but the main thing for me was the routing matrix, which is pretty cool to have. Latency - The latency in CC mode is better than my Firewire interface, but still a bit worse than the rme. For now I succeded to run a medium session (25 Channels with processing and fx) at 64 frames buffer size with 3 buffers. Certainly not bad. While playing guitar and singing I didn't feel any of this annoying delay that you sometimes get when the latency is bad. Sound quality - Pretty good. I have nothing to complain about... Though I can't really hear the supposedly amazing ESS converters stand out from the other professional DAC crowd... To be honest in the Studio I'm working happily with the old Alesis HD24xr AD/DC to make 1/0 out of my precious electrons... The Preamps are pretty clean sounding from my firswt impression, but I really didn't have enough time to toy with them. The channel count is huge for my terms. 64 in and out... That should be enough for me. Though I didn't get around to check if the AVB connection does really work on Linux. To summarize I'm feeling that we are moving in the right direction here... I hope other manufacturers will follow and make Interfaces and software that work with Linux... Cheers Moshe

DrumGizmo v0.9.14 (LAC2017 version) released

by Bent Bisballe Nyeng

DrumGizmo version 0.9.14 now available! Get it at http://www.drumgizmo.org/ DrumGizmo is an open source, multichannel, multilayered, cross-platform drum plugin and stand-alone application. It enables you to compose drums in midi and mix them with a multichannel approach. It is comparable to that of mixing a real drumkit that has been recorded with a multimic setup. This is a bugfix release fixing a lot of bugs as reported from our last release 0.9.13[1] which was the first drumgizmo version ever supporting diskstreaming. The release bears the version number 0.9.14 and can, as always, be downloaded here[2]. For the full list of changes, check the roadmap for 0.9.14[3]. The release of 0.9.14 is also known as "LAC2017 here we come!" As is a bit of a tradition for the DrumGizmo team (and many other fine open source projects), we have prepared a special release for the upcoming Linux Audio Conference[4]. This year the conference takes place in Saint-Etienne, France from May 18-21 2017. And we'll be showing up! So be sure to take note of “The cool guys with the drumsticks”. You might just secure yourself one with a nice DG logo on it done with the custom made lasercutter of Open Space Aarhus[5]. See you at LAC! :) [1]: http://www.drumgizmo.org/wiki/doku.php?id=roadmap:features_roadmap#version_… [2]: http://www.drumgizmo.org/wiki/doku.php?id=getting_drumgizmo [3]: http://www.drumgizmo.org/wiki/doku.php?id=roadmap:features_roadmap#version_… [4]: http://lac.linuxaudio.org/2017 [5]: http://osaa.dk

Re: [LAU] Motu 1248 - Full success

by Anders Hellquist

I just bought a couple of Ultralite AVBs the other day since I got a really good offer. Have not received them yet so I have not tested them. I have been following for some time the development of the openAVB project and I really hope this standard is getting more widely spread. What I cannot understand (well I can understand but not embrace) is the fact that every vendor except AVB-switch vendors have their own implementation and by design make their products compatible only with its own brand. The point with a standard is IMHO to make products able to talk to each other. Motu apparently enabled talking to some Avid equipment some time ago with a new firmware but non-Avid brands are not compatible AFAIK. I guess this is only marketing trying to protect their own brand more than a pure technical decision but correct me if I am wrong. Do you guys think that AVB devices "firmware" easily cold be changed by the vendor to accept and cooperate with other avb streaming equipment ? Do you think it is possible to reverse engineer the vendor specific protocols like for instance the FFADO project has been doing with firewire to make future openAVB implementations for the linux kernel if one is using appropriate hardware (intel i210 or similar) ? Or is this already possible ?

Realtime sound level measurement with logging

by Jonathan Gazeley

Hi folks, I'd like to set up sound level monitoring for my office, with periodic logging. I have a handheld meter but I'm really looking for a way to use a traditional condenser microphone and USB audio interface to measure the level with some kind of windowing, and log it periodically to a file (maybe once per minute). Is there a decent application that can monitor and log data in this way? I'm also open to the idea of just recording a WAV file over 24 hours and doing the analysis afterwards, with periodic readings from the file. Is my approach reasonable, to set up a microphone and use the gain knob to calibrate it against the handheld meter? I don't need amazing accuracy. We've just moved into a large open-plan office for the first time and it is very noisy (handheld meter says about 50dB of air handling noise measured at my desk, rising to 60dB when there is background talking). I want to monitor sound levels throughout the day to test my theory that people are more noisy in the afternoon, and to get an overnight control reading with the people gone and only the air handling and computers running. Thanks, Jonathan -- Jonathan Gazeley Senior Systems Administrator IT Services University of Bristol

LAC2017 special edition :) Some highlights. We now implement the fairly new LV2 StateChanged message. The current MIDI- learned list is now included in state saves. MIDI- learned NRPNs can now be set as 7bit Lots of info and an updated "Short Yoshimi Guide" in the tarball doc folder. Many 'switches' are now learnable. To build yoshimi fetch the tarball from either: http://sourceforge.net/projects/yoshimi Or: https://github.com/Yoshimi/yoshimi Our user list archive is at: https://www.freelists.org/archive/yoshimi -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.
