Re: [LAU] Best practices when using jackd over a LAN.

by Len Ovens

It has been some time since I tried netjack (or zita-njbridge). At least one machine upgrade... Also, you may want to look into open AVB which has jack to jack capability and with the right nic will allow your audio stream to have priority over other network traffic. But it is more to set up. In any case, if there is more than one audio card some resampling will have to happen (even with AVB with most consumer AIs). In the case above, your hifi will have to be master I am not sure in that case why there would be a server in the middle, but it looks like you have the server getting it's sync from the hifi and then the laptop gets it's sync from that? Is the network used for other things besides sound? Is audio traffic prioritized? In all machines? In any switches? Looking into AVB and or AES67 and the requirements for no dropout sound may be helpful. Netjack is designed for single hop, no other network traffic, no switch, audio transport. zita-njbridge is designed to handle switches and some other traffic a bit better. The standard streamers like icecast, etc. use long latency end to end (500ms or more) to avoid dropouts. So in the end you have to choose your own priorities in sound quality and latency as well as how much money you want to spend and how much time setting it up. -- Len Ovens www.ovenwerks.net

[ANN] Vee One Suite 0.8.5 - An Autumn'17 release

by Rui Nuno Capela

Howdy! The 'Vee One Suite' of so called 'old-school' software instruments, synthv1 [1] as a polyphonic subtractive synthesizer, samplv1 [2] a polyphonic sampler synthesizer, drumkv1 [3] as yet another drum-kit sampler and padthv1 [4] as a polyphonic additive synthesizer, are here released for the seasonal greetings. All still available in dual form: - a pure stand-alone JACK client with JACK-session [5], NSM (Non Session management [6]) and both JACK MIDI and ALSA MIDI [7] input support; - a LV2 instrument plug-in [8]. The common change-log for this Fall goes like this: - Sample files are now saved as symlinks when saving to JACK and/or NSM session directories/folders (applies to samplv1 [2] and drumkv1 [3] only). - Opening multiple preset files is now possible, populating the preset drop-down listing, while only the first one is loaded effectively into the scene as usual. - Mono(phonic) "Legato" mode option introduced. - Desktop entry specification file is now finally independent from all build/configure template chains, whatever. - Updated target path for freedesktop.org's AppStream metainfo file (formerly AppData). And now, in reverse order of appearance: **padthv1 - an old-school polyphonic additive synthesizer [4]** padthv1 0.8.5 (autumn'17) released! padthv1 is an old-school polyphonic additive synthesizer with stereo fx padthv1 is based on the PADsynth algorithm by Paul Nasca, as a special variant of additive synthesis.

FWIW, I haven't used a FTP in Linux for some time, but when I did, occasionally I got the same thing: clean output, distorted input. I guessed that the endianness disagreed. But it was sporadic. So you're not crazy. It really does happen and it's not a hardware problem with the box. I don't have a solution, though. hjh

Re: [LAU] ffado and new PC

I did note on my other machine where this all works that alsa does see the AF12, as does jack. I rarely look at alsa, so I have no idea how to tell if the fw alsa driver is loaded. At least some part of alsa it is there since if I select it as the driver with jack_control and start jack it finds the sound devices on the MOBO. AS I said this behavior of UBS install is new to me, since it has always just found everything. Of course the only common things are the AF12 and UBS 16.04. The MOBO, fw card, etc. are new.

JACK netmanger to trigger the execution of a bash script on client connect/disconnect?

by Athanasios Silis

Hi all, after starting JACK2 manually (no DBUS, no KX studio session or anything automatic, other than starting it from /etc/rc.local on boot up) on jack master server, I also start the netmanager and wait for jack clients to connect. jack_load netmanager When clients connect I have them ssh to this jack master server and run a script about what connections are necessary between the master's sound card and the client's exposed ports. This is fine and works if jack clients lose lose connection and have to reconnect. This does not work well when something is wrong with the jack master and the audio is restarted. The clients will reconnect and the client will pop up (f.e. in qjackctl), but the necessary connections will not be reestablished. The ideal way to automate this would be to have jack master take care of all its connections and have netmanager trigger the execution of a script when a client connects. How can I do that without using application requiring an X server (thus a bash script)?? More specifically I want to know how I can trigger a script that carries out the connections, not what should the script contain... Thank you in advance for your help!

firewire-thunderbolt adapter?

by Bernardo Barros

Hello I have a quick question. I have an old MOTU Ultralite that works well with a thinkpad, which has a firewire I/O. Current Thinkpads don't have firewire, but some have thunderbolt. My old soundcard would work on a new thinkpad with an adapter, like it does with other OS's? Thanks! Bernardo
