[LAD] [LAU] [LAA] Guitarix 0.35.5 released

[Hermann Meyer]

Guitarix release 0.35.5

Guitarix is a tube amplifier simulation for
jack (Linux), with an additional mono and a stereo effect rack.
Guitarix includes a large list of LV2 and LADSPA plugins, and support 
LADSPA / LV2 plugs as well in it's racks.


The guitarix engine is designed for LIVE usage, and feature ultra fast, 
glitch and click free preset switching and is full Midi and remote 
controllable (the Web UI is not included in the distributed tar ball).


This release fix a issue within the new online preset downloader.
If you already use V0.35.4, a upgrade is strongly recommended.

'wordclock' was part of the data packet.


It is not word clock. but wall clock with high accuracy so word clock can 
be derived. It is possible to do an end point without by treating packets 
in the same way as as buffer in an audio card where alsa does not have 
to be aware of the exact clock rise or fall to deal with it. However, If 
you wish to send audio from an internal audio card to any aes67 endpoint. 
Your computer must be able to be provide an ntp server with good enough 
accuracy to provide wordclock to both your internal audio ai and to act as 
a master clock on the network... or be able to sync your internal audio 
card to an external ntp server. This accuracy pretty much requires a HW 
ntp server. As I said the intel i210 ethernet cards at $60-ish seems to be 
about the cheapest route.


Depending on how synced you want things... SRC can do a very good job and 
the broadcast industry uses it a lot. The zita-njbridge does a great job 
of connecting two computers together and I suspect using the zita src 
library as part of an aes67 driver would make  ethernet card 
workable so long as the computer was never expected to be a master clock. 
So an aes67 network with only two linux computers may not be usable or at 
least your network would not be wholely aes67 compliant. An endpoint with 
no ntp able to follow a masterclock closely doesn't seem fully compliant 
to me from what I have read. So the windows drivers downloadable from 
various places would have the same problem of not being fully compliant 
too. Some of the MacOS hw does have an ethernet chip with builtin ntp 
server.


So a driver that does what the windows driver does should be possible.

How powerful of a computer would be required for a software based
solution to be able to keep up with a (expensive for now) ravenna
card, if one wanted full channel count at full data rate?

I understand that it travels over an RJ45 port with standard wiring
(cat 6). I assume one would want an additional dedicated ethernet port
for this.

I'm considering learning C just to take this on.


there is a driver, but so far as I know not open source. While it is 
probably possible to make an AES 67 endpoint that will work with one aes 
67 box. I do not think a full endpoint that becomes part of the aes b67 
network is possible without a hw network clock as the intel i210 ethernet 
cards have. Concidering the cost of Ravena interfaces AVB may be a 
better bet anyway. There are open drivers for avb... if unfinished. there 
seem to be some afordable avb audio interfaces around too.


Still, if you have access to a revena interface, go for it.

BTW, the intel i210 cards seem to be cheaper from hp than from intel, or 
they were when I bought mine. Same card...

[LAD] Anyone working on software implementation of Ravenna for Linux?

[Bearcat Şándor]

Has anyone encountered any work on this?

How powerful of a computer would be required for a software based
solution to be able to keep up with a (expensive for now) ravenna
card, if one wanted full channel count at full data rate?

I understand that it travels over an RJ45 port with standard wiring
(cat 6). I assume one would want an additional dedicated ethernet port
for this.

I'm considering learning C just to take this on.
