Love Linux, hate getting it to work with audio!

[jackelliott]

Hi,

New here, my name is Jack, I live in Bend, Oregon (USA). I do a couple of FM+streaming radio shows on our local community radio station and I'd like to be able to use my little Linux netbook to perform some easy -- or should be easy -- audio stuff, stuff that is indeed easy to do under Windows, but am having quite a time trying to figure out how to do them under Ubuntu Linux.

Things like opening a network stream in a media player, such as VLC or Gnome MPlayer, and getting Ardour to record that stream. Can't seem to get Ardour to see the stream. Jack and PulseAudio, and Alsa all seem to be involved and been having a heck of a time sorting them out so Ardour can record the network stream.

I've been all over the Internet looking to see if this wheel has already been invented, and I'm pretty sure it has been, but having no luck finding the village of people who are using this wheel. Perhaps this is one such village.

If it sounds like I'm in the right place, point me to the right forum and I'll post a Help Me!

You should be able to create your files directly in VLC without needing Ardour.

Go to ==> media ==> convert/save

Choose the network tab and enter your url

Click convert/save down at the bottom

Choose a file name and a file format from the drop down menu (& select display the output if you want to hear it as it records).

Click start


Hope this helps.
Guy

Thanks, English Guy,

I'm not so much interested in recording the file or listening to it (since I'll be doing the show, live, myself) as I am in seeing -- visually -- its waveform, in real time, while the show is happening. Like when making a live recording. But in this case the source would be something like Gnome M player playing the radio station's live stream.

I don't think that VLC provides a marching waveform visualization.

I could use VLC to record the file, then bring it home and load it into a DAW to look at the waveform, but that would be after the fact.

(Should this be moved to one of the actual help forums?)

This might work:

https://build.opensuse.org/project/show ... sov:Nulloy

The windows version of this, or Foobar 2000 running in wine might also be able to do it,
if the linux nulloy does not.

Meterbridge has accurate metering, if that would be useful in the interim,
use jackd aware player like aqualung, or audacious or vlc with jack plugin,
to route the stream, and using qjackctl to connect the i/o (lots of youtubes
of qjackctl, if it's not familiar)

Robin Gareus provide a couple of realtime analysis tools in LV2 plugin format. If you use jack for your stream, you could easy use them.
