USB Soundcard with stereo input & output

varunsrin — Tue, 16 Jul 2013 04:20:54 -0400

I'm looking for a USB sound card, that meets the following criteria:

Has decent Linux driver compat
Has a stereo line-in and stereo line-out (most cards have a mono line-in for mics)
Is small (usb thumb drive size preferably)
Doesn't alter or process the sound (e.g. THX enhancements)

Right now, the only devices I've found are:

http://www.cooldrives.com/usb20auadbox.html [ a little too large for what I want]

http://www.amazon.com/electronics/dp/B0044DEDC0 [not sure if it supports Linux, and seems to modify the signal]

Thanks in advance if anyone has experience with this - haven't had much luck searching for it online.

Audio stops in Ustream

When broadcasting on Ustream using Ustream Producer, every 20 minutes the audio stops. Why does this happen? Is there a setting that can be changed? Someone please advise. Thanks!

Audio USB-streaming

Tommy Skogsberg — Wed, 15 Sep 2010 14:45:49 -0400

Hello.

Audio-streaming is becoming increasingly popular and there are several programs that can stream for example PCM-signals to a soundcard.

Now I have a CD-player with a really good DA-converter that can recieve and play digital PCM-signals from another DVD player through an optical or coaxial cable.

My question is: -How do I make the computer send the PCM-stream straight to the CD-players digital inlet? For instance through the USB outlet straight into a coaxial cable?

Is that possible, mabe some kind of handshake between the machines is needed?

I have been thrugh the SOX manuel papers without finding a solution. Is there a hacker out there that can enlight me on this subject?

Kind Regards / Tommy

What software will multiplex sound inputs?

codebunny — Thu, 22 Jul 2010 15:58:10 -0400

My computer has one of those crappy sound cards that only takes input from one source. I run fvwm2. I play music all the time. If I browse to a website that plays sounds, like YouTube, then no sound comes out from my browser, and then Firefox locks up tight. I have to kill the individual firefox processes and restart it.

KDE and (I think) Gnome have some lowlevel software that acts as a sound multiplexor. It sits above the crappy sound card and allows multiple sound inputs. What is this software? Can I use it without using KDE?

EDIT: At the low end, I am using ALSA for sound. At any given time, there are only two programs that are going to play sound - one is mplayer and one is Firefox. I think both these programs are trying to get sole ownership of /dev/dsp to play sound. Are there settings that will cause mplayer and Firefox to pass the sound to some underlying device that will multiplex the sound? Arts? Esound? PulseAudio?

Firefox is using mplayer as a plugin to play audio. Is there a way to configure the mplayer plugin so it doesn't go directly to /dev/dsp but to the multiplexor?And is there some configuration for mplayer on the command line that would pass the sound to the same thing?

Make mp3s louder

Troy — Sun, 16 May 2010 11:48:15 -0400

I have my iPod loaded with music and generally listen to it through my car stereo. Inevitably, there are very loud songs; I have to turn the stereo down to 4 or 5. There are also very quiet songs; I have to turn the stereo to 20 or 25 to hear them properly.

Is there a way to increase the loudness (if that is the correct term) of the quiet mp3s so that I don't have to turn the stereo up to such a large volume?

Ideally it will be a non-destructive change and reversible if the results sound horrible. It should allow me to specify an mp3 with the target loudness and make the other mp3s as loud.

The mp3s are mixed and generally not from the same artist or album. It would also be nice to get a report of the changes before they are made so I can listen for my self to see what would happen.

Thanks, Troy
