[LAU] caustic with wineasio

Hi

I'm having a blast with caustic (music environment for android, ios,
windows + more). It works fine through wine, but for better realtime
performance, I'd like to get it working with wineasio.

I have wineasio working with reaper, so I copied the dll.so from that
folder to .wine (freshly made, only used with caustic):

atte <at> skagen:~/.wine$ find | grep asio
./.winelib/wineasio.dll.so

I then registered it with:
atte <at> skagen:~/.wine$ regsvr32 .winelib/wineasio.dll.so
Successfully registered DLL .winelib/wineasio.dll.so

I have this in my ~/caustic/config:

atte <at> skagen:~$ cat ~/caustic/config
B ALLOW_SCREEN_ROTATION TRUE
I KEYBOARD_KEYSIZE_PORTRAIT 1
I KEYBOARD_KEYSIZE_LANDSCAPE 1
I PIANOROLL_KEYSIZE_PORTRAIT 1
I PIANOROLL_KEYSIZE_LANDSCAPE 2
B WHATS_NEW_310 FALSE
I INTERNAL_LATENCY 1
S SOUND_DRIVER ASIO

Still, caustic refuses to play, and right upon launch I get this in the
terminal that started caustic:

[LAU] Xruns :(

Recently I updated my 'office' computer, which I often use for experimenting
(I don't try anything new on the DAW) and suddenly I'm getting a *lot* of Xruns
and, apparently, very high CPU loading.

Eventually I found the cause. Going from linux kernel 3.2 to 3.16 :(
This, apparently, does very aggressive CPU frequency scaling. Drop back to 3.2
and all is sweetness and light again.

The question is whether there is a reasonably straightforward way to stop this
behaviour. Doing the usual searches doesn't seem to turn up anything useful.

Any help gratefully appreciated.

I would add that I've double checked that the bios is set for 'performance'.

[LAU] jack and the merging of soundcards

I may perspectively run into a shortage of audio inputs and stumbled 
across a blog, that reads like it is possbile to "merge" two soundcards 
into one virtual, that eventually looks as a single one to alsa. 
However, that blog does not mention jack.

Also, in an stone old ardour thread Paul Davis suggests to a similar 
problem: ", then you simply get 2 digifaces", but again, this may have 
been before the rise of jack.

And now I am wondering wether this is a possible or even reliable way to 
trick jack into being able to to finally handle more than one soundcard, 
if presented by alsa as being a single one.

I am honest, that asoundrc is way beyond me, as alsa alway has been, 
thats why I am asking and I am thinking about using two ordinary, 1st 
generation, pre HDSP, Hammerfall cards to expand ADAT IO. Would be 
cheaper than investing into a raydat, when time has finally come.

The posts for reference:

Any thoughts on this? Or won't it work with jack?

You can adjust the sound of the click and program tempo changes through a text file. There are no options for swing type feels, but any meter is supported. It is command line only and not open source yet. A word of caution, if importing into Ardour be sure to change the output name to something besides click.wav.

[LAU] Adventures in concatenating ogg files

I've for months now been struggling (like Don Quixote, it appears) to find a way to RELIABLY, and with
tolerance of any kind of error, concatenate several Ogg Vorbis files-- some with multiple streams in
them-- into one.

At first I was trying to do it without decoding. Wrote a bunch of tools in several languages attempting to do
that. None of them worked for all cases (some worked for a few, some worked for none).

The existing tools out there--  sox, mplayer, ffmpeg--  all require decoding/re-encoding, but even with
that they failed on various edge cases (multiple streams in a file, streams with zero audio data, empty
files, etc).

I finally ended up with the only thing that sort of worked and handled ALL the edge cases, even though it
requires decoding and recoding audio, which wastes CPU and also might introduce artifacts, which was
this magical pipeline:

 ogg123 --audio-buffer 0 -q -d wav  -f - files-to-concat/*ogg  | oggenc -Q - > total-file.ogg

Except for one problem.

Any shows longer than 3:22:53 get concatenated to 3:22:53. What's special about that number? Oh, I bet it is
a size_t overflow in probably the total number of decoded bytes at 44.1khz.

If my math is correct,  44.1khz, 2 channels, 16 bits, 3:22:53 is 2,147,317,200 bytes. Ding.

Now what? Go digging through the source of ogg123 or oggenc looking for the problem, and try to patch it?

Ogg Vorbis has been a released standard since, what, 2000? Is it possible in 2014 that I'm the only person who
has ever run into this problem?

[LAU] Generating click tracks

Hi,

I am wondering, wether there is a way to create click tracks. Audacity 
is quite limited, as it only creates quarter note clicks, while the 
upper tempo setting is limited, so f.e. you cannot create 16th for 
120BPM by means of scaling up the BPM.

Also, there are no triple notes, swing eighth or syncopated options 
available, though I am afraid, those will be rather seldom, if availble 
at all.

Are there any alternatives, that are at least a little more flexible 
than audacity?

I am not talking about recording a plugin, like a softsynth, which is 
liable to the internal (midi) clock oscillation, but generating an audio 
track with really accurate clicks

[LAU] No ffmpeg, help convert script for Sox

Well that was a surprise, to see that ffmpeg has been fully removed from 
Ubuntu now. Not sure how much of a better move that is, compared to the 
very underhand tactics of having it a renamed package which in reality 
had nothing to do with real ffmpeg. Not sure I want to get into the 
politics of the situation here though, sure most of you know far more 
than I do!

Anyway I have a little script for batch converting flacs to mp3s as I am 
rather space conscience while travelling and my mp3 player never liked 
ogg. My Bash skills are near zero and what I have working is messy from 
searching on the internet for a solution. Hopefully you can help me 
modify it to use Sox rather than ffmpeg. (And possibly make it so I can 
simply call the command, rather than the more complex command I have to 
use currently.)

To start the process I currently use this command in the terminal:
find  -type d -exec ~/bin/flac2mp3 "{}" \;

The previously working contents of flac2mp3 was:
#!/bin/bash
if [ -d "${1}" ] ; then
   cd "${1}" && for f in *.flac; do ffmpeg -i "$f" -f wav - | lame -b 
320 -m j -q 0 - "${f%.flac}.mp3"; done
fi

I tried quickly to edit.

#!/bin/bash
if [ -d "${1}" ] ; then
   cd "${1}" && for f in *.flac; do sox "$f" -b 16 "${f%.flac}.wav" - | 
lame -b 320 -m j -q 0 - "${f%.flac}.mp3"; done
fi

Seems to think the .wav is an incoming file for concatenation.

#!/bin/bash
if [ -d "${1}" ] ; then
   cd "${1}" && for f in *.flac; do sox "$f" -b 16 "${f%.flac}.wav" | 
lame -b 320 -m j -q 0 - "${f%.flac}.mp3"; done
fi

Gives me all the wav files converted but doesn't then pass them onto the 
lame section of the command.

I'm sure this must be really simple! (As much having it all in one 
single script called by just executing the file!)

Regards, Dale.
