Hi,
I like to speed up my boottime of my Mac Mini / Instrument module. I'm
thinking about buying a SSD drive.
How are SSD drives performing these days and how reliable are they? What
about a SSDH drive?
Regards,
Dirk

Ah, hmm. It seems maybe this isn't the disaster it seemed. I had a memory
that VST support on Linux was shaky and on dodgy legal footing, but perhaps
it's moved on or I've had the wrong end of the stick.

My subscription lapsed a while back and there were some problems getting
it set up again for some reason I forget. At the time I have up but the long
and short of it though is that I *should* be subscribing and so I've tried
again and it seems to be working now.

Hello,
Very minor thing. Wondering why, in the configuration, interface
option, not all interfaces are directly listed in the drop down box.
Instead, one must press the arrow at the right of the box to see more
interface options. Wouldn't it be simpler to just list them all in one
drop-down box ?
I asked this on the liquidsoap list but nobody there seems too interested in this subject.
I have DJ's streaming from various parts of North America and Europe to a Linux VPS in New York.
Many of the DJ's have periodic dropouts where their sound goes away, and its annoying.
The liquidsoap software logs the buffer status at every packet received.
So I've been logging this stuff. I see a strange pattern.
The DJ's streaming from California who have good internet connectivity (some don't; I'm not including them in my data) show a buffer that steadily decreases, until it drops out and there are 2 seconds of the backing jukebox playing, until the buffer catches up.
The DJ's from New York show perfectly solid buffer status. The buffer fills, and stays filled for hours. One DJ even has a buffer that increases in size as his show goes along!
A separate station I've set up, streams from a Linux PC in California to a Linux VPS in California... rock-solid buffer status.
Now, I've been told that the buffer problem is due to clock synchronization on soundcards. Some soundcards on't stream exactly at 44.1khz, they're like 44.0Khz, and that causes a buffer that gradually declines in size, as it's been explained to me.
But!
Why would everyone in California have "slow" soundcards and everyone in New York have "fast" ones? That seems very unlikely.
I'm assuming everyone is using random soundcards, mostly SoundBlasters or HDAINtels. The mix of OS's is very random: two Linux guys, the rest mostly Winbloze, one or two Macs, and there's no geographic pattern. Almost everyone is using the same GPL streaming software-- The BUTT-- though one is using Nicecast I think.
I'm told that the power grid AC mains sync is not uniform across North America and that the east coast is at 60.1Hz or similar, the west coast at 59.9Hz, but that's irrelevant, it's all rectified/regulated +5V by the time the soundcard (and its clock crystal) sees it.
The obvious answer here is just network latency, since one set of DJ's are streaming locally and the others are traversing a continent. And I might just have to do some kind of time-stretching to avoid dropouts.
But what about this business with the sound cards? Is that a red herring?

I've just been taking a look at the user guide for RecordMyDesktop, which looks
very simple and easy to use (has jack support).
Does anyone have any experience of using this?
Is there an equally easy way to add captions later?
How about making a copy suitable for youtube?
Should I be using something completely different?
Am I asking too many questions? :)

Say you have a poem and I have a tune.
Exchange them and we can both have a poem, a tune, and a song.
I went looking for the linuxDSP stuff recently and found that sadly it
appears to be being shutdown (or moved to another company, with no support
for the LV2 plugins).
Has anyone got a link to a summary of the "recent uncertainty" in the
linux audio world that's referenced in the text?

Hi all,
i'm attempting to connect a slave jack running on windows 7 64bit and a
jack master running on linux ubuntu studio 14.04 64bit.
jack is verified to be 1.9.10 on both sides.
firewall is also completely open between windows and linux.
the 2 ends can ping each other - no problem
jack master is running on alsa and with netjack2 also running. other linux
pc's connect without a problem to this jack master.
but jack slave running from windows does not show up on master jack... what
can I assume is wrong?
mtu have not been tampered with.
jack slave on windows states:
C:\Program Files (x86)\Jack>jackd.exe -dnet -i2 -o9 -C8 -p8

I am using 'tcpdump' on the *jack master* to listen for udp packets on port
19000 (where jack broadcasts by default). the cmd is:
tcpdump host <ip_of_jackd_client> and udp port 19000
In turn I checked some linux clients and the windows client:
linux cl1 (ip 192.168.112.133 - name jackcl1)
16:10:39.532802 IP jackcl1.19000 > jack_master.58548: UDP, length 44
16:10:39.533960 IP jack_master.58548 > jackcl1.19000: UDP, length 1500
16:10:39.533970 IP jack_master.58548 > jackcl1.19000: UDP, length 204
linux client 2 (ip 192.168.112.144 - name jackcl2) looks similar
16:23:09.842778 IP jackcl2.19000 > jack_master.54735: UDP, length 204
16:23:09.842782 IP jackcl2.19000 > jack_master.54735: UDP, length 564
16:23:09.843880 IP jack_master.54735 > jackcl2.19000: UDP, length 1500
16:23:09.843890 IP jack_master.54735 > jackcl2.19000: UDP, length 204
unfortunately it looks like the windows jack client sends out the packets,
but the jack master never responds...
16:11:52.040582 IP wincl1.19000 > jack_master.19000: UDP, length 644
16:11:53.528440 IP wincl1.19000 > jack_master.19000: UDP, length 644
16:11:55.028455 IP wincl1.19000 > jack_master.19000: UDP, length 644
can you make anything out of that?
thank you in advance for your help.
Hey hey,
since I've started with WONDER, I found that the documentation covers all OSC
commands and config formats, but there's not much explanation of the OSC
commands. In many cases the commands are self explanatory, but in some
instances, I need clarification.
What does the source/angle command affect?
Is there any way to affect the z component of an audio source?
What does the rotationDirection do?
I haven't heard any effect from the rendering of the room/polygon. Does it
only render the original room, h0104 and fail on other specs?
Finally in the speakers config file I am confused. Specifying a positve
y-coordinate places the speaker behind the listener? So the normaly (normal
vector component) has to be negative in that instance?
If any one can answer all or any of these: you can be assured of my gratitude!

I was just playing with the "swing" knob in Hydrogen's mixer and I can't
hear the effect. Can anyone who has used it or knows exactly what it does
to the note timing give me any context for this?
Is it a subtle swing effect that might be lost on a mere guitarist such as
myself or should I be able to hear something pretty dramatic going on?
