I'm running a new Arch Linux system now and have come up against the
The Arch Wiki suggests several alternatives, the old, the new and the new new
way. The latter being only suitable for JACKD with DBUS support, which I don't
have. As far as I'm aware, the DBUS version only works with X running, which I
don't want, all the time.
Unfortunately, the Arch Wiki isn't accessible right now, so I can't post the
proper link. But the described metho uses shell scripts setting PulseAudio
sink and source modules to JACK and default sources and sinks to jack_in and
I start JACK through a self-written systemd service. Should I start PulseAudio
by default as well? Can such a shell script with Pulse settings be executed at
startup as well?
I'm sorry to raise the topic again, but I'm so very new to that snake pit.
I'd be grateful for any tips, reading material for that situation.

Sometimes you get so bogged down in problems that you tend to forget what it's
all about. Well, after a series of seemingly intractable coding issues on
Sunday, I decided to take a break and instead pootle about on my DAW.
Picking up a barely started project I'd laid aside, for once things went
surprisingly smoothly, and this was the result. I hope you enjoy it.
The icing on the cake? It turned out to be a perfect match for this months KVR
competition theme :)

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 have just released an update of the AVL-Drumkits (now at 1.1). For
those who are unfamiliar these are free sample libraries of 2 complete
Drumkits and hand percussion in Hydrogen, SFZ and Soundfont2 formats.
These kits are intended to bring an authentic acoustic, organic drum
sound to your MIDI DAW arrangements and preserve real-world
characteristics such as tom ringing and overtones unlike many General
MIDI kits that sound sterile. AVL-Drumkits feature 5 sample layers per
kit piece, have a very light memory footprint and are suitable for
systems old and new. The shell samples provide both center and edge
hits to emulate right and left hands and the cymbals are quite
realistic without truncated samples. Additional resources are
available such as a PDF Keymap and Midnam files to use with MIDI
tracks in Ardour and Mixbus.
* - Now licensed CC-BY-SA  with a slightly modified license
(Thanks to Nils Gey)
* - NEWLY ADDED SOUNDFONT2 VERSIONS! (tested with the new 'a-Fluid
Synth' plugin in Ardour 5.4)
* - Cleaned up formatting of SFZ text files with better key number
ordering (didn't affect performance, just my OCD)
* - New Kick drum samples for both kits with fuller sounding closed
Downloads, more detailed information and Audio and Video demos of the
Kits can all be found at the AVL-Drumkits webpage:

Hi Linux audio users,
My band's debut album has just been released for high quality streaming on
SoundCloud. Track 4 is also available for free download.
Previously only track 4 was available on there. The album was available for
streaming on BandCamp since June, but the streaming quality was terrible.
Ellipsis was recorded and produced entirely using free open source software
such as Ardour, ZynAddSubFX, Hydrogen, etc. It was released June 2016.
Check out the official website for info on how to buy or donate if you like
I welcome any feedback on the album.
I have a super cheap C-Media USB Headphone Set based sound card (it's all
over ebay as a guitar-link).
It isn't awful quality wise (I was expecting worse, although it did require
a bit of soldering to get it working at all..), so I'm interested in
getting it working well, however when I run duplex jackd I have a problem:
With -p64 -n3, approx every minute the recorded audio gets corrupted for
about 15 seconds, then it sorts itself out for another minute. I've
uploaded an example of the problem with a sine wave input here:
If I change to -p128 -n3 it happens approx every 2 minutes, and it doesn't
happen in input only mode from what I can tell.
Has anyone got any thoughts?

Recently I embarrassed myself by making and posting a piece that used
material created by another composer (fortunately a friendly one). When
notified of the issue I immediately withdrew the piece from circulation
and apparently all's well that ends well.
However, on reflection I find that I am a very disorganized person who
has amassed a huge number of soundfiles over the years. I've tried to
keep them organized, but I could really use a file manager dedicated to
managing soundfiles. I'd like to click on a file and see the kind of
information displayed by sfinfo and similar utilities. I'd also like to
see the file's metadata in the same display.
Does such a file manager exist ? How do you manage very large
collections of soundfiles ?
Updates now available at the usual place:
*** Regarding zita-ajbridge: If you experienced unexplained
*** and repeating 'Excessive timing errors', this release will
*** fix those (unless there really is a problem).
- Added VResampler::set_phase
- Maintenance and small bugfixes.
- Fixed bug in DDL computing timing of Alsa periods.
Thanks to Tomasz Kasprzak for the bug report and fix.
- Fixed bug in automatic selection of resampler quality.
Previous release always used a short filter unless
the lenght was explicitly set.
- Fixed bug in DDL computing timing of network packets.
- The data format 'on the wire' has changed. It should
be backwards compatible, but to be sure please use this
release on both ends.
A world of exhaustive, reliable metadata would be an utopia.

As i recovered an old hard-disk-drive from the 90's (30MB HDD form an
i386 DX40) i could reap one of the oldest MIDI files i 'recorded' under
DOS (or win31 ?) with an MPU-401 while i was not twenty years old yet. I
don't remember which software i used at this time...
The midi was not quantisized and needed some polish, so i rewrote it on
Musescore tonight after listening carefully to the original.
Its name was 'essai3 ' (third try). But i found i could rename it as
'Life of a zebra', just for fun:
I hope you will enjoy this short tune as i had pleasure to rediscover it ;-)
How is the avplay binary, part of libav, produced at compilation
time ? avconv and avprobe are produced and installed, but there's no
sign of avplay. configure only have a --disable-avplay option. The
make log shows no sign of avplay but shows the compiling of avprobe and
avconv. libav is configured simply with:
This is libav-11.8.
What is the incantation to have avplay built ?
