Is LUBUNTU a suitable option for audio-recording tasks?

[joaquinotero]

Also, Im still getting that message at lubuntu logo startup. its stating that Lbuntu is going to start without full network configuration and the resulting delay is anoying when Im not connected to internet.

No idea but I agree that this is super annoying. So if I find anything how to disable this I'll post it here.

Thanks mate, ¿I wonder if anyone else has experienced this "network issue" at startup?

Oh yes: http://www.google.com/search?q=ubuntu+w ... figuration

Indeed, I found some people that have found a "way" to get rid of that network message, and as far as I understand, its related to Dbus (the same that was causing error messages at Qjackctl in my configuration?).
By th way, ¿what is the job/function of Dbus?

[AutoStatic]

D-Bus is a message bus system, a way for applications to talk to one another.

In my case the wating for a connection message is probably because I updated from an older Ubuntu release on some of my machines.

For metal sounds, you may also want to try out Guitarix. With some experimenting I have found some very nice and pleasing amp sounds.

As for Rakarrack, I am one of the developers for the project so I can authoritatively agree that Rakarrack is not geared toward metal by design (not on purpose, it just takes time to implement these things well).

The program started as an effort to port much of the effects engine from ZynAddSubFX synthesizer to a guitar player friendly interface. From there, more guitar-oriented modules have been added, but the distortion related things have not seen much development.

Probably the most likely to get close are whatever you can get out of the StompBox module. This one includes a 'sort of' model of the Boss Metal Zone and the DOD Death Metal distortions. In my opinion, stompbox distortions (real or software-implemented) don't stack up to the sound you get from a nice tube preamp.

This is where Guitarix steps in and offers a lot of flexibility to virtually build and tailor a custom amp to your own liking. Like anything configurable, it takes time and a bit of a climb on a learning curve (although I find Guitarix interface to be really intuitive, and it's improving all the time).

I enjoy using Guitarix and Rakarrack together. I use them similarly to how one might use a mic'd amp in a separate room with a rack-mount digital FX processor.

On other hand maybe is a matter of time to learn to tweak guitarix adequately.

Yes, Ive already downloaded guitarix, but Im still getting some little fizzied-sounding tones, theres some interesting presets (JP) but theres a lack of high freq that makes guitarix comparative to Nick Crow's Simple Combo or SimulAnalog's JCM900 (IMHO).
Please dont get me wrong, Im still tweaking guitarix, maybe is a matter of my lack of abilities with ampsims and only a matter of time to get similar tones to other ampsims (Lepou, Serina, Ignite).

I didnt update from an older ubuntu version. As you know, I fresh-installed from ubuntu miminal CD, everyone who has updated from an older version states this issue, but thats not my case.
Could this be a bug of Lubuntu 12.04?

By the way, none of the solutions posted on ubuntuforums worked for me. ¿Did you get any solution?

I also have this same exact issue (boot delayed for 2 mins waiting for network). I haven't found a solution yet, and I'm actually giving up on it...

If I plug a network cable before turning on the laptop, it boots fast as usual, otherwise there's the 2min pause.

I think his doubt is what dbus in jack is for. I have the same doubt. I run jack over qjackctl wit dbus-option unchecked. When would you check this box, and what for?
Ladish f.e. needs jackdbus but manages jackd on it's own. So I wonder what this is all about.

disabling LAN in bios?

disabling LAN in bios?

Installing Lubuntu offline (Im pretty sure), but this is only possible for the whole installation (not the minimal or core as I wanted).
I wonder if performing a whole Lubuntu installation and later uninstall all programs would give me the same results (regarding HD & RAM usage).

Im getting this message from Jack everytime it starts:

I would like to record 48Khz/32bits.FP; but this message:
"...ALSA: final selected sample format for capture: 16bit little-endian..."

states that Im not getting 32bitFP signal incoming, isnt it?

How could I do to get 32bitFP signal at recording?.

Also, Im getting this message form Xfburn everytime it starts:
"...Failed to initialize gstreamer transcoder: An error occurred setting gstreamer up for transcoding
(falling back to basic implementation)..."

Thanks in advance for your help.

The value reported as 16-bit is the resolution of your sound card's A/D converter. The incoming signal will be 16-bits, but Jack processes EVERYTHING at 32 bit floating point or greater, so this is converted by default (if you have a 64-bit machine, it will be 64-bit float).

Of course, it is on you to use a preamp to make sure you're getting the full dynamic range of your 16-bit card...you can decrease the quality significantly just by feeding your computer a weak input level.

That being said, you will be recording 32 bits if you have succeeded at getting JACK to start.

As you may know, the reason for 32 bit floating point is more important for any signal processing you may be doing as it improves the accuracy of filters, etc...so if you weren't using any plugins or doing any processing on the signal, this would be irrelevant, since you can't improve the accuracy beyond what you get from the sound card.

About Guitarix, I do understand what you mean about the treble not being as sharp. It may be all you need to do is use the convolver with a good amp cabinet response. I think the built-in cabinet simulator is EQ-based, but the convolver will give you as good of a cabinet response as any impulse you have recorded (for example, if you hijack one of the IR files from a commercial amp-sim, you will get equal results (for the cab response). The distortion/preamp tone is probably limited by the model they use...but I guess it's a matter of taste. Amp sims are getting better, but for the whole experience of a real amp, you just can't replicate it.

However, from the perspective of audience/listener, the difference will not be noticed, so it's really us picky musicians who care. A good guitar player sounds good even when using crappy gear that would disgust most people...anyway...

Hi transmogrifox

I think the built-in cabinet simulator is EQ-based,

Just a side note, the cabinet simulator isn't EQ-based, it's Convolution based.
The EQ (and Level controller) you see in the module, tune the impulse data before it get convolved with the input signal.

The distortion/preamp tone is probably limited by the model they use...

Well, the latest git include a tube screamer model now, witch helps a lot on that.

About Guitarix, I do understand what you mean about the treble not being as sharp.

To get sharper high frequency’s, the biquad filter and/or the feedback module will help.

I will post samples of Lecto&IRLV2-RedwirezFreeMarshall and Guitarix, maybe an example is better to describe what Im getting from both programs.
Youre right, the sound depends a lot on the guitarist; but Im not a good guitarist, until I get improvement at my hands, I have to carefully select what gives better timbral results.

By the way, thanks for your comments about samplerate-bit depth. Sure, I will do some post filtering, so I will record at 48kHz-32bit FP.
