i am not sure if this hardware section is the proper place to put this question but my problem is like this. I want to record headphone mic input in a local file every time my system boots up and broadcast the real-time audio or rather multicast it through local LAN
View 1 RepliesI'm using a fedora install mainly for audio work and have everything working well out of the box. My setup is simple:
-Direct cable from Guitar 1/4" > Sound Card input>Rakarrack Guitar Effects>Ardour>System Out
(Occasionally I put a synth/plugin like Zynaddsubfx or jackrack before or after rakarrack depending on what sound I'm going for)
-Jack for all audio transport with synthesizers
I have real time support with Jack and all other programs except Rakarrack. When I launch Rakarrack in the terminal, I get this message:
Code:
rakarrack 0.6.1 - Copyright (c) Josep Andreu - Ryan Billing - Douglas McClendon - Arnout Engelen
Try 'rakarrack --help' for command-line options.
Cannot lock down memory area (Cannot allocate memory)
Cannot use real-time scheduling (RR/15)(1: Operation not permitted)
AcquireRealTime error
However, running rakarrack in root does not display this output, and I assume it has no problem getting real-time scheduling in that case. I did some google searches but the only similar issues that I find are that people can't get RT support in jack except in my instance, I do have RT scheduling with jack, but for some reason I can't get it in rakarrack unless I'm root.
[Edit] I actually have to run jackd and rakarrack in root to get rakarrack to use real time scheduling. But, it isn't necessary for any other jack compatible program that I know of. I'm actually not getting any real time scheduling with any jack application, even though Jack is reporting to be running in Real Time. However, running everything in root fixes the issue even though I would prefer to not have to run as root.
I am currently trying to start doing some screen casting and having a problem with audio recording in gtk-recordmydesktop. The problem is that I need to record both; my computers audio card output, and my mic input at the same time. As of now I am able to record one or the other.
View 4 Replies View RelatedI was wondering if there is an application for Ubuntu (FOSS or otherwise) that would allow me real time management of all of my audio inputs and outputs. Essentially I have multiple microphones attached to my computer and multiple audio outputs. What I am looking to do is to be able to assign each different input to it's own audio output. A touch screen interface is a plus for the program but not necessary.

View 1 Replies View RelatedI used the following command to get the unix time of root user creation:
Code:
awk -F":" '$1 == "root" {print $3}' /etc/shadow
How can i convert this into the date/time of creation?
I am writing a shell script, which determines the OS installation date among other stuff, and i am assuming the root user's account creation date should be a pretty accurate pointer. Are there reasons why i should not be assuming so?I would be open to other suggestion for getting this date/time, but it would nevertheless be interesting to convert the unix time to "real" time without doing complex manual(or otherwise) computation..
I'm just working on fedora for the first time for my proj. So having many difficulties. My first doubt is that is it possible to record audio in single user mode using fedora?

View 2 Replies View RelatedI need to set the default input device to be the microphone on my webcam for when I skype, but it seems to keep resetting itself, so I keep going in and changing it.

How do I stop it from forgetting this and resetting it?
I can play audio in my alsa system and I can record. To keep things simple, I use arecord to record and aplay to play. So far so good. The problem is, I cannot hear what I am recording as I record it. Is there some way to get the input to be echoed to the output? I would optimally like to be able to do this before recording as well as during, so that I can check the levels, find the part to record on the tape, beforehand.
I have tried a test of my card: I had aplay running in one term and arecord running in another. They both ran fine and when I checked the just-recorded file, it was different audio from what I had been playing. This would indicate that the card is able to input and output at the same time, I think? I've done the usual googling as well as reading through URL... and I have done many passes of trial-and-error on my .asoundrc. The more I look at my .asoundrc, the more it looks like it should be doing what I want, but it is not.
My .asoundrc (which again, does works but does not echo audio input):
Code: Select all# pros: this allows playback and record. Playback of several
# programs at the same time works (their outputs are mixed
# together, mono and stereo mixed to stereo)
#
# cons: input is never echoed!

I've got the following problem:
1. I start two bash windows
2. In one of them I start a script test1:
Code:
This script puts a natural number 5 times a second.
3. Then in the second bash window I type (as root):
Code:
The script test2 looks as follows:
Code:
While true; do
true;
done
During the following 15 seconds test2 is the process with the highest real-time priority. As far as I know the script doesn't perform any system calls so it shouldn't be suspended even for a minimal timeslice. My question is: why the process test1 manages to put a few numbers on the screen before test2 stops. I thought that test2 would exclusivly own the processor for 15 seconds.

Using arecord works perfectly with hw:0,0. I had also tried to use /dev/snd/hwC0D0 as input but I receive an error from alsa saying that it doesn't exist (despite it existing and having adequate permissions). I know absolutely nothing about hardware but am comfortable around the command line
Running qjackctl as root allows me to run the audio in realtime so it seems to be a permissions problem and it seems to me that lubuntu does not read the /etc/security/limits.d/audio.conf file when I boot.
View 3 Replies View RelatedI have a linux router box with ubuntu which routes internet for several people. There is no extra traffic shaping, so everybody can get the whole bandwidth when its free. What I would like to have is a real time traffic counter per ip, just like a program called "iptraf" but on a per-ip basis. Iptraf can only count on a per-connection basis and thus cannot display a bandwidth that a certain ip has taken (because a single ip can start several onnections). So a console program with text interface like iptraf would be perfect - does anybody know about such a program? After some googling I came to the conclusion that such a program does not exist (which must be wrong - i think that per-ip real time traffic flow information is the first thing every router owner would like to know).
