| brycebudd | hey all, can someone point me to a url that will list what services I can safely disable for recording with ardour? | 16:13 |
|---|---|---|
| holstein | services? | 16:14 |
| holstein | like ssh and the like? | 16:14 |
| holstein | you need JACK running | 16:14 |
| brycebudd | correct system services | 16:14 |
| brycebudd | understood | 16:14 |
| holstein | i dont see any reason why you should disable any services though | 16:14 |
| holstein | i mean, disabling what you arent using is safe of cours | 16:14 |
| holstein | e | 16:14 |
| brycebudd | Let me phrase it a different way...what are the essential system services to safely run an ubuntu system and gain maximum system performance and memory? | 16:16 |
| holstein | that all depends | 16:17 |
| holstein | are you using USB? | 16:17 |
| holstein | firewire? | 16:17 |
| holstein | do you need networking? | 16:17 |
| holstein | is this an audio production rig only? | 16:17 |
| holstein | i would start with this... what do you *not* need | 16:17 |
| holstein | like maybe bluetooth | 16:17 |
| ailo | brycebudd: My experience is that you don't gain a lot as long as you have a good kernel. Even not installing the entire desktop makes little difference | 16:17 |
| holstein | i say, at the end of a few hours of tweaking, you will really reclaim nothing useful | 16:17 |
| brycebudd | yes, audio only... | 16:18 |
| holstein | theres no reason to disable a bunch of services for doing audio | 16:18 |
| holstein | *maybe* doing video, you *might* notice | 16:18 |
| holstein | audio really isnt all that hard on the sytem | 16:18 |
| holstein | system* | 16:18 |
| brycebudd | ailo: thanks for sharing your experiences...that's exactly the kind of feedback I'm looking for! | 16:19 |
| ailo | It's not so much about cpu and RAM, more about priorites | 16:19 |
| ailo | And the kernel handles that + jack + settings | 16:19 |
| brycebudd | so in your opinion what are the best ways to measure and reduce latency, reduce xruns etc. Is it just playing with settings or are there "magic settings" that generally work. | 16:20 |
| holstein | that depends on the hardware | 16:20 |
| brycebudd | I usually use Jack, Hydrogen, Seq24, Patchage, and Ardour | 16:21 |
| holstein | if you are using an internal soundcard, i wouldnt expect under 20ms latency | 16:21 |
| brycebudd | unfortunately...only USB. No native cards | 16:21 |
| holstein | USB is sometimes better | 16:21 |
| ailo | brycebudd: Just make sure you have realtime priority for the user. Other than that, it might mostly depend on the type of kernel, as well as the kernel version | 16:21 |
| holstein | and at least its external, and typically cleaner | 16:21 |
| brycebudd | I've been getting 11ms reported in JACK using M-Audio | 16:21 |
| holstein | 11 is pretty good | 16:22 |
| holstein | tolerable | 16:22 |
| holstein | depends on what you are doing | 16:22 |
| brycebudd | recording drum tracks with a Roland TD-20 | 16:22 |
| holstein | if you do no live instruments, or effects processing.. who cares if it takes 70ms for the sound to come out the speakers | 16:22 |
| ailo | brycebudd: Is that an external synth? | 16:22 |
| ailo | alsa midi is really lousy when it comes to external midi gear | 16:23 |
| brycebudd | no electronic drum kit. I can sync to Seq 24 via MIDI. | 16:23 |
| brycebudd | ailo: what is better? | 16:23 |
| ailo | jack midi is better | 16:24 |
| ailo | Not all apps support it yet | 16:24 |
| brycebudd | ah...I will play around with that tonight. Thanks for the tip!! | 16:24 |
| ailo | brycebudd: Choose "seq" as the midi driver in qjackctl | 16:24 |
| brycebudd | good! that's what I'm using (I just didn't know it) *blush* | 16:25 |
| ailo | brycebudd: If you're using the lates jack, alsa midi will still be active | 16:25 |
| brycebudd | ailo: should I disable? if so how? | 16:26 |
| ailo | Jack midi supported apps will appear in the "MIDI" tab, and not the "ALSA" | 16:26 |
| ailo | Just make sure the app you use is set to jack midi, and not alsa midi | 16:26 |
| brycebudd | ailo: I get it...understood. thanks! | 16:27 |
| brycebudd | byebye | 16:29 |
| neyder_ | hi!, in precise, how can i install the audio metapackage ober an edubuntu installation' | 16:31 |
| holstein | neyder_: i would just open the package manager of your choice, and search "ubuntustudio" | 16:32 |
| holstein | i would also consider just installing what you are wanting to use.. JACK, ardour... hydrogen... for example | 16:32 |
| holstein | sudo apt-get install ubuntustudio-audio should get you the metapackage you are looking for though if you prefer | 16:33 |
| neyder_ | gret, i was asking because "apt-cache show ubuntustudio-audio" tells me that is a transitional package to Audio Seed | 16:38 |
| neyder_ | *great! | 16:38 |
