[LAU] mplayer no go with snd-hdsp

Hi,

I've recently gotten my RME Multiface up and working quite
satisfactorally with current Linux kernels. I'm very happy, especially
as I had a long run of it not working for some reason I never teased
out.

So, I find I can aplay and arecord, and I can use ecasound, and a few
other cli tools.

But, I can't use mplayer. Am I the only one? Anyone else tried mplayer
on the Multiface?

For cli tools mplayer gives me the ability to pause, or move backwards
and forwards through the audio file. This is important to me because I
learn music these days by ear.

I know one can do this in the gui, but as a blind user the Linux gui
audio apps aren't particularly friendly in my experience. Besides, it's
so terribly simple, if rather imprecise, to use spacebar, left-arrow,
and right-arrow.

The error I get:

Opening audio decoder: [pcm] Uncompressed PCM audio decoder
AUDIO: 48000 Hz, 2 ch, s16le, 1536.0 kbit/100.00% (ratio:

[LAU] Update to "Robust Session Management"

A major rewrite; quite a lot faster and better now, was needed for an 
enormous patch in the works:

[LAU] Ardour: Recorded regions in one track to individual tracks

Hello dear all.

Some time ago, maybe years because I think it was Ardour2 at that time, somebody asked if anyone knew a non-manual-tidious way to have all the playlists of one track in Ardour converted to individual tracks. This was to be able to Solo/Mute each take to filter the best ones instead of constantly changing playlists.

Well, I would like to refresh that question (for Ardour2 and Ardour3 now) and ask more or less the same again but for individual segments in a track that were recorded on a tracking session. The reason why this segments are all in the same track is that they were recorded by the same person who was playing and at that moment it was quicker to do like that instead of having to deal with playlists in every recording track or several new tracks one for each take and source recorded.

I guess there are many DIY musicians that have experienced this and maybe come to a solution, or maybe there's some functionality in Ardour I'm not aware of.

Thanks in advance as always.
Regards.

[LAU] Sound Devices - USBPRE 2 - Status ?

Hello everyone.

Looking for a external sound card with good preamp to record.
Found the Sound Devices USBPRE 2 suits my need.
Browsing the web, the Sound Devices web site  and this list, it seems to be supported for  UAC1 with no trouble but only with 48khz.
The message is now old :
http://linuxaudio.org/mailarchive/lau/2013/1/25/196179

Anyone can give some update about the UAC2 status with Alsa on this card ?  Please.

ps: running a Gnu/Debian Stable.


Best.

[LAU] ALSA resampling

Being lazy here, so quick question:

I'm looking for a simple way to resample in ALSA from a capture/play interface that supports only 48kHz, to
44.1kHz which is desired.

Both playback and capture resampling is needed, and it seems I neeed dsnoop and dmix.

However, I am bewildered by the somewhat byzantine configuration of .asoundrc.

There's one card on this machine, a "SB LIVE!" (which means "48kHz only!"), running the emu10k driver.

There's no JACK up in this at all, it's just an old streaming PC running BUTT. There is also no PulseAudio
because I avoid PulseAudio.

If I were using ices2 I suppose I could use its built-in resampling, but that's not an option in this case.

[LAU] Smoothing congas

Hi,

  Congas (in this case Wavedrum congas # 19) have sometimes hits louder
than others.  Eg. the player hits more forcefully at times. What would
be a good way to even out the output (recorded in Ardour) so that the
stronger hits do not stand out as much in the mix ?

Cheers.

Very cute.

However, there are no real standards. Each program, opensource or not, has its 
own system and ne'er the 'twain do meet. So one restricts to one  program, no 
other choice.

Microsoft is so big so makes its own standards, its own rules, changes them at 
will (example rtf), but they are not in the DAW business. Just many programs 
run on their platform so may use some of their file-structures.

What if the programs we use here, on this list, were inter-operable? 
Ardour/Harrison, Qtractor, Muse, Rosegarden, etc. We have more choices than 
does Microsoft. What if Tracktion (proprietary, now supporting Linux!) were 
brought on board? I do not think it is so far-fetched if there be a will to do 
so. One opensource library to service this, done once.

(I no longer have my old posts, proposals for this. Discussion was a while 
back.)

[LAU] another cpu question

Hello all,

I may be putting together a box dedicated just to act as a multitrack 
effects unit - without planning any recording. The effects stack will 
for most channels most likely look like this: reverb, delay, EQ and 
maybe one of flanger, chorus or rather seldomly compression. Anyway, 
just the classics, planning so far to only to install the calf and 
invada lv2 packages. Though I am open for recommendations here, too. And 
of course I am looking for a suitable effects host/rack.

However, I do suppose, the reverb will be the most cpu consuming item 
and I am wondering, what feature an a cpu should I be primarily looking 
for? I guess, for effects, especially reverb, the floating point 
performance will be paramount?

As HT generally has a bad reputation for audio, currently, the AMD 
FX-8350 is on top of my list, as the floating point preformance is said 
to be rather good and lots of cores should be ideal for running lots of 
effects in parallel - though unfortunately not every core does have its 
on FPU. As it is not going to run 24/7, the insane energy consumption is 
somewhat acceptable.

But, beeing no coder, I may be completely off track with my conceptions 
here, so I am asking for some more insight or alternative 
recommendations, maybe even with a short reasoning

Thanks

Ede

[LAU] Suppress the GUI of calfjackhost?

I'd love to be able to run one of my standard calfjackhost chains, with 
a command-line switch to suppress GUI.  Is there a way?

[LAU] Common DAW session save / import

Hey all,

So I know a standard exists for Pro tools to save to a interchangeable format for import to Mixbus via a 3rd
party software app. Forget the names.

Point is, it would be awesome to be able to save basic sessions in Ardour and be able to import the track info,
edits, etc, into say, Qtractor or Muse or whatever. 

What's out there per open source or proprietary solutions. Is this something that could be collaborated on
in house so to speak?

I use Mixbus for the most part. But for live recording on an older sony Vaio, it's just too much of a CPU pig!
Qtractor is a 1st choice solution for me. After the session has been saved, it would be great to be able to
import that session to Ardour / Mixbus. Lining up all track data manually is a pita! 

Thoughts? Work arounds? Other open source DAW's?

Fanx! :)

[LAU] [ANN] Vee One Suite 0.5.1 - One second official beta release!

Howdy,

The gang-of-three aka. the Vee One Suite of old-school 
soft(ware)-instruments, featuring synthv1 [1], a polyphonic synthesizer, 
samplv1 [2], a polyphonic sampler and drumkv1 [3], as a drum-kit 
sampler, are once again released in beta phase though.

The changes for this one second beta release are the following:

- Fixed LV2 plugin relative/absolute file path state resolution. 
(drumkv1 [3] only).
- One decimal digit added to all scalar parameters and knobs.
- Stand-alone JACK client ports outrageously renamed from a zero based 
numbering scheme into a plus one natural one.
- Experimental LV2 Time/position atom-event support (Delay BPM).

Please, don't hesitate to ask whether any of the above esoteric babbles 
doesn't get you on to update as soon as you can. One special note goes 
for all the users out there of drumkv1 [3] LV2 genre: the update is not 
just interesting but a must, seriously ;).

As usual, all is available in dual form:

- a pure stand-alone JACK [4] client with JACK-session, NSM [5] (Non 
Session management) and both JACK MIDI and ALSA [6] MIDI input support;
- a LV2 [7] instrument plug-in.

The Vee One Suite are free and open-source Linux Audio software, 
distributed under the terms of the GNU General Public License (GPL) [8] 
version 2 or later.
