Hi,
Ubuntu Studio 16.04. Was looking for tempo estimators.
I see online: https://aubio.org/manual/latest/cli.html#manpages
``
NAME
aubio - a command line tool to extract information from sound files
COMMANDS
...
tempo get overall tempo in bpm
``
So I installed python-aubio (which was already installed, I think for pd) and aubio-tools. Then:
$ which aubio
(nothing)
Does anybody know what's up with that? The one thing I could think is that the commandline tools are new (documentation is for 0.4.5), but xenial ships 0.4.1. In which case I'd try building myself.
Or, any other tools for tempo estimation? I tried BeatTrack in SuperCollider, but it's based on a 1024-point FFT; with overlap=2, its timing resolution would be limited to 512 samples (and I found, in fact, that it would oscillate between two values, as if occasionally correcting for timing inaccuracy).
Thanks,
hjh

Hi,
I wonder if it is possible to control an iPad synth app like Animoog
from a DAW running on Linux (something like you would do with the
iConnect MIDI 2 on Win/Mac systems).
I am running Bitwig 2.2 on Linux Mint 18.1 Serena. I use the Allen &
Heath ZED10FX as class compliant USB device.
Cheers,
Oliver

Yes, I do. Where do you think are the original Apple products made?
The quality of a Chinese fake could be better than the original Apple
product. If somebody should have bad luck, than it still was worth to
pay a few €, before buying an Apple original product.
If somebody wants to spend that much money, than better directly get
30pin to USB,

I tested one, it works but doesn't work better than the cheap CCK, so I
gave it back to the dealer.
Btw. the Focusrite's Scralett line also provides cheaper audio
interfaces.

My Chines CCK works, too.

Adapters and cables don't include anything that could explode. Btw.
my original iPad's charge cable jacked is made from plastic that
crumbles, the Chinese replacement is already old, too, but doesn't
suffer from such a bad jacket.
Dear all,
It is my pleasure to announce the First International Faust Conference
(IFC-18)! We look forward to see you in Mainz this summer.
Cheers,

[Apologies for cross posting, please circulate widely.]
1st International Faust Conference - Johannes Gutenberg University, Mainz
(Germany), July 17-18, 2018
The International Faust Conference (IFC-18: http://www.ifc18.uni-mainz.de)
will take place at the Johannes Gutenberg University
<http://www.uni-mainz.de/> of Mainz (Germany) on July 17-18, 2018. It aims
at gathering developers and users of the Faust programming language
<http://faust.grame.fr/> to present current projects and discuss future
directions for Faust and its community.
Participants will be able to share their work through paper presentations.
A series of round tables on various topics will serve as a platform to
brainstorm on Faust's features, semantics, tools, applications, etc. to
determine future directions for this language. Open spaces for demos and
workshops will be available for participants to openly share their ongoing
projects with the rest of the community.
As a special event, the winner of GRAME's Faust Open-Source Software
Competition will be announced during IFC-18.
IFC-18 is free and everyone is welcome to attend!
*Call for Papers*
We welcome submissions from academic, professional, independent
programmers, artists, etc. We solicit original papers centered around the Faust
programming language <http://faust.grame.fr/> in the following categories:
- Original research
- Technology tutorial
- Artistic project report (e.g., installation, composition, etc.)
Paper should be up to 14 pages in length, non anonymous, and formatted
according to this template
<http://www.ifc18.uni-mainz.de/misc/IFC-18-templates.zip>. *Submissions
should be carried out via our EasyChair portal
<https://easychair.org/conferences/?conf=ifc18>*.
All submissions are subject to peer review. Acceptance may be conditional
upon changes being made to the paper as directed by reviewers.
Accepted papers will be published on-line as well as in the IFC-18
proceedings paper version. They will be presented by their author(s) at
IFC-18 as 15 minutes presentations (+ 5 minutes for questions).
Feel free to contact us if you have any question.
*Important Dates*
- Papers submission deadline: March 2, 2018
- Notification of Acceptance: May 1, 2018
- Camera-Ready Version: June 1, 2018
*Call for Round Table Topics*
A series of round tables on the following themes will take place both
afternoons of IFC-18:
- Faust Tools (e.g., Architectures, IDE, Faust Code Generator, On-Line
Services, etc.)
- DSP in Faust and Faust Libraries (e.g., New Algorithms, New Libraries,
Missing Functions, etc.)
- Faust Compiler and Semantics
- Other Topics/Open Session
We solicit topic suggestions from the Faust community for each of these
themes. Topics can be submitted by means of this Google form
<https://goo.gl/forms/0fBYxk28jlRdtqRM2>. They will be introduced during
the round tables by the session chair.
*Contact*
Please, address your questions to: ifc18(a)muwiinfa.geschichte.uni-mainz.de

Recently, I recorded some additional tracks into an Ardour session, and
the new tracks turned out great, but some levels were changed on some of
the already existing material that shouldn't have been changed, and I'd
like to get my old levels back. I never created a snapshot in Ardour
before these fader level changes.
Fortunately, my machine makes backups every night, and I have a copy of
my old project folder from backups. It's thus possibly to use rsync to
zap my whole project folder back to the way it was before, get my
levels, and then zap it back to its new state again.
I was just curious though:
Is it possible to use the .ardour and/or .history files from my old
backed up folder to get the snapshot I should have made? Is it possible
to recover these files, copy them into the new state of my folder, and
use them as snapshots without changing a lot of other things? The
reason I ask is because snapshots behave a lot like Ardour session
files. (I haven't dived into the internals; maybe they are Ardour
session files?)

Hi
I have been using jackd to play music from my laptop -> server -> hifi.
It works well apart from I will get dropouts in the audio now and
then. I have been looking at the options for client and server and
trying all sorts of things to try to fix the dropouts, but I can't
seem to cure the problem.
My laptop is connected via cable rather than wifi.
NIC on laptop:
Ethernet controller: Intel Corporation 82579LM Gigabit Network
Connection (rev 04)
NIC on server:
Ethernet controller: Broadcom Corporation NetXtreme BCM5751 Gigabit
Ethernet PCI Express (rev 21)
Jackd command on laptop:
set_rlimits /usr/bin/jackd -dnetone -n60 -I0 -O0 -r44100
Jackd command on server:
set_rlimits /usr/bin/jackd -P 10 -p128 -t10000 -dalsa -dhw:DGX,1 -r48000 -p128 -n3
-P -I32
jack_netsource -H raven -r50000 -n1 -i2 -o2 -I0 -O0
I've been trying out different latency settings on server and client,
but they either don't make any difference, or jackd refuses to start.
Any ideas for getting rid of dropouts/xruns on the network?
Dave
Hi list,
I have been search the archives and the web a bit and it seems there is
no easy way to route html5 audio playback from firefox through jack on
Debian testing.
Is this still the case or has there been recent development that might
enable it? What would have to be done to make it work? This
functionality is the last piece in my puzzle to finally get rid of
flash.
thanks for pointers,
P

Have you also tried zita-njbridge?
It has been some time since I tried netjack (or zita-njbridge). At least one
machine upgrade...
Also, you may want to look into open AVB which has jack to jack capability and
with the right nic will allow your audio stream to have priority over other
network traffic. But it is more to set up.
In any case, if there is more than one audio card some resampling will have to
happen (even with AVB with most consumer AIs). In the case above, your hifi
will have to be master I am not sure in that case why there would be a server
in the middle, but it looks like you have the server getting it's sync from the
hifi and then the laptop gets it's sync from that? Is the network used for
other things besides sound? Is audio traffic prioritized? In all machines? In
any switches?
Looking into AVB and or AES67 and the requirements for no dropout sound may be
helpful. Netjack is designed for single hop, no other network traffic, no
switch, audio transport. zita-njbridge is designed to handle switches and some
other traffic a bit better. The standard streamers like icecast, etc. use long
latency end to end (500ms or more) to avoid dropouts.
So in the end you have to choose your own priorities in sound quality and
latency as well as how much money you want to spend and how much time setting
it up.
