[LAD] detailed spectrum for wide freq range

by Andrew Gaydenko

Hi! I have an audio file (say, ~10 seconds) and want to see detailed spectrum at wide range (say, from 10Hz up to Fs/2). There is excellent FA's jaaa analyzer (and I use it at constant base), but it has linear freq axis, while log scale is more appropriate at the case. Off-line (not real-time) analysis (with as well as possible quality) would be appropriate. Suggestions? Andrew

[LAD] [ANN] QjackCtl 0.3.6 - Full D-Busification!

by Rui Nuno Capela

Awe! Times they are a-changing although Bob Dylan has no D-Business here. The old and cutie gooey for JACK just got one turn around the verge of bit-rotting. This time it brings full JACK D-Bus support, or almost. It also adds D-Bus access for most GUI actions which some might find pretty handy for keyboard shortcut binding from your desktop environment of choice. However, if babies health is your top concern you can just turn this D-Bus thing off and play with the old times ;) Ahem... QjackCtl 0.3.6 is now released! More details in the change-log, below. Website: http://qjackctl.sourceforge.net Project page: http://sourceforge.net/projects/qjackctl Downloads: - source tarball: http://downloads.sourceforge.net/qjackctl/qjackctl-0.3.6.tar.gz - source package (openSUSE 11.2): http://downloads.sourceforge.net/qjackctl/qjackctl-0.3.6-2.rncbc.suse112.sr… - binary packages (openSUSE 11.2): http://downloads.sourceforge.net/qjackctl/qjackctl-0.3.6-2.rncbc.suse112.i5… http://downloads.sourceforge.net/qjackctl/qjackctl-0.3.6-2.rncbc.suse112.x8… - binary packages (Ubuntu 8.04): http://downloads.sourceforge.net/qjackctl/qjackctl_0.3.6-1.rncbc.ubuntu804_… http://downloads.sourceforge.net/qjackctl/qjackctl_0.3.6-1.rncbc.ubuntu804_… - binary packages (Ubuntu 9.10): http://downloads.sourceforge.net/qjackctl/qjackctl_0.3.6-1.rncbc.ubuntu910_… http://downloads.sourceforge.net/qjackctl/qjackctl_0.3.6-1.rncbc.ubuntu910_… Weblog (upstream support): http://www.rncbc.org License: QjackCtl is free, open-source software, distributed under the terms of the GNU General Public License (GPL) version 2 or later. Change-log: - Make sure socket names are unique on each side of the Patchbay (another patch from Dominic Sacre, thanks). - A bunch of primitive D-Bus interface slots have been added, allowing shortcut access to most of main applications actions like toggling Messages, Status, Connections, Patchbay widget pop-ups, reset stats, transport and so on. New bindings are given eg. via dbus-send --system / org.rncbc.qjackctl.(main, messages, status, connections, patchbay, setup, about, reset, rewind, backward, play, pause, forward). (from an original idea from Sebastian Gutsfeld, thanks). - Patchbay snapshot now tolerates JACK client port strings that have more than one semi-colon in it, honoring just the first one exactly as everywhere else eg. Connections. (a glitch as reported by Geoff Beasley while using a2jmidid). - Most modal message dialog boxes (eg. critical errors) are now replaced by system tray icon bubble messages where available (mitigating feature request #2936455). - Comply with jackd >= 0.118.0 which now runs in real-time mode by default; use of -R is now deprecated from the jackd command line interface options; use -r to run in non-real-time-scheduling. - A man page has beed added. - Got rid of a pretty old and never really useful "jackd-realtime" server path option--actually, it was only seen available on the now defunct old Mandrake Linux distro. - D-Bus support, as provided by org.jackaudio.service aka jackdbus, is now being introduced and used wherever available and whenever enabled. Configuring, starting, stopping and logging the JACK back-end server through the "infamous" jackdbus service is now being seamlessly exploited. - Global configuration state is now explicitly saved/committed to disk when Setup dialog changes are accepted and applied. - Server name command line option added (-n, --server-name). - Single application instance restriction option added (X11). - Setup for the netjack (slave) "net" driver has now sample-rate and frames per buffer (period size) settings disabled and/or ignored, as those are pretty much auto-detected by default; also, a new "netone" backend driver option has been introduced (as suggested by Torben Hohn). - Czech (cs) translation added (by Pavel Fric). - Fixed some main window keyboard shortcuts. Escape key now closes Connections, Patchbay, Status and Messages widgets as usual (bug #2871548). - Fixed glitch on configure portaudio support, specially when the library is not detected as available. Cheers && Enjoy. -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

Re: [LAD] [LAU] Descent synth as dssi

Even better if it saves its state in a format that is human-readable and can be diff'ed, or put into git for versioning. it doesn't change anything about how applications save state. it merely provides for a unified way to initiate a save, and a unified way to restart everything back in the same state (or as close as each individual application will allow.

Script, or text explanation? Screenshot? Ardour audio project only? I'd love to have a rather bullet proof way to make my sessions available to non-geek collaborators really fast and easy. And vice versa. Software trying to outsmart the user can be painful. On the other hand, there are users out there waiting to hop on the linux audio boat as soon as there is an obvious way to save and restore complex setups without scripting. I'd love to make music with them. It's good that you are happy with your way of using your DAW and so am I. But it makes me a little sad sometimes that for remote collaborators the learning curve is so steep. - Burkhard > -ken > _______________________________________________ > Linux-audio-user mailing list > Linux-audio-user(a)lists.linuxaudio.org > http://lists.linuxaudio.org/listinfo/linux-audio-user

[LAD] List of latency testing tools and tips

by Dan Kegel

I couldn't find a good list of audio latency testing tools, so I put one together at http://wiki.winehq.org/MeasuringAudioLatency Did I miss any good ones? Also, do any of them work? :-) I just tried the one in lib-alsa, and it isn't happy.

[LAD] [ANN] Drumstick libs 0.3.0 released

by Pedro Lopez-Cabanillas

Drumstick is a C++ wrapper around the ALSA library sequencer interface using Qt4 objects, idioms and style. ALSA sequencer provides software support for MIDI technology on Linux. Complementary classes for SMF and WRK file processing are also included. This library is used in KMetronome, KMidimon and KMid2, and was formerly known as "aseqmm". Changes: * Split into two libs: drumstick-alsa and drumstick-file * Parse Cakewalk WRK files included in drumstick-file * Some fixes and API additions. See the ChangeLog for details.

[LAD] [ANN] QmidiCtl, QmidiNet 0.0.1 - New Kids On the Block

by Rui Nuno Capela

Greetings, QmidiCtl [1] is a MIDI remote controller application that sends MIDI data over the network, using UDP/IP multi-cast. It has been designed primarily for the Maemo [3] enabled handheld devices, namely the Nokia N900 [4]. In its current development state, which is obviously alpha as of this writing, it puts a mini multi-track recording control surface on your hands and on-the-go, so to speak. MMC is the feature and yours truly Qtractor [5] the target. However, any other MMC enabled DAW may be considered. However nothing of this would be possible without this little thing that gets also here its release announcement: QmidiNet [2] is a MIDI network gateway application that sends and receives MIDI data (ALSA Sequencer) over the network, using UDP/IP multi-cast. Fundamentally inspired by multimidicast [6] and designed to be compatible with ipMIDI [7] for Windows, it's a little tiny application that sits as an icon on your system tray and exposes one or more ALSA Sequencer client ports which open the way for a MIDI network mesh. Pretty neat if you think wireless and not necessarily because of QmidiCtl [1]. Alas, you can transform any Linux/ALSA computer (or Windows/ipMIDI [7] enabled one, if you dare to) into a MIDI-over-IP inter-connected node.
