Purpose of this LV2 extension is to standardize realtime safe allocations in a plugin. Plan is, host to provide functions that plugin can call. Pointers to functions are provided through host feature. Only memory pool (fixed chunk size) functionality is defined. Attached is early draft of the header. Doxygen generated from it documentation is available at: http://svn.gna.org/viewcvs/*checkout*/lv2dynparam/website/doxygen/lv2__rtme… Any comments are welcome. In particular about whether general purpose allocator (arbitrary memory chunk size) should be part of this same extension. -- Nedko Arnaudov <GnuPG KeyID: DE1716B0>

Detecting one sample within another

by Patrick Marchwiak

Given a sample clip, I would like to be able to find in another audio file a part that sounds similar to the clip. So for example, given a cymbal sample, I would like to be able to find a part of an audio file that sounds similar to a cymbal. I am not interested in beat detection, but rather just getting a single slice. Having only a basic grasp of digital audio theory I am wondering what algorithms would be applicable for this situation. I am also new to Linux audio, so I would appreciate any pointers to libraries that provide this functionality or means to implement it myself.

[OT] F7 security

by Fons Adriaensen

Somehat off-topic, but at least it's about systems to be used for audio exclusively... Help ! I'm struggling to get 5 computers running F7 configured. In the Gnome destop there's the app that lets you configure the firewall and selinux. It asks for the root password so I assume that when that's given I can do what I like. But everything I modify there (adding allowed ports for some networked audio apps) is silently ignored. Same if I try to disable the firewall. I must be ignoring something very simple... -- FA Laboratorio di Acustica ed Elettroacustica Parma, Italia Lascia la spina, cogli la rosa.

It will help them, but not with hardware ALSA seq MIDI ports, because currently a2jmidid ignores them. This can be fixed easily in code until a2jmidid gets more configurable. > Once there's a new jackd release, with the -X option, will this too be > needed anymore? It will still be needed for users that want using raw ALSA MIDI backend (and skipping additional ALSA sequencer layer). This is setup I have here, I use -X raw but I still need connecting legacy ALSA MIDI apps to JACK MIDI apps. Althrough not intentional, it may help for JACK drivers that don't support JACK MIDI nativily yet. IIRC JACK MIDI ffado driver support is not ready yet. -- Nedko Arnaudov <GnuPG KeyID: DE1716B0>

[ANN] a2jmidid version 2 released

by Nedko Arnaudov

a2jmidid is daemon for exposing legacy ALSA sequencer applications in JACK MIDI system. It is based on jack-alsamidi-0.5 (jackd alsa seq midi backend) by Dmitry Baikov. The main purpose is to ease usage of legacy, not JACK-ified apps, in JACK MIDI enabled systems. New in this release is addition of configure script (autotools) that enables compatibility with different JACK MIDI API variants. Planned features/improvements: * One JACK client per ALSA sequencer client * More control on what ports to bridge (currently bridging is fixed to non-hardware ports). * Real daemonization with log file, init.d script, etc. If someone wants to contribute please, contact me, or send patches, or request inclusion (Gna! a2jmidid project). As usual, packagers are more than welcome too. Homepage with screenshots: http://home.gna.org/a2jmidid/ Tarball download: http://download.gna.org/a2jmidid/ -- Nedko Arnaudov <GnuPG KeyID: DE1716B0>

[PATCH] japa-0.2.1 colors customizability improvement

by Nedko Arnaudov

Here is a tiny patch to improve japa-0.2.1 colors customizability. I created it to achieve outlook that can be seen here: http://nedko.arnaudov.name/soft/japa-0.2.1-colors.png I'm also attaching configuration file I use to achieve the outlook. FYI, example conf file is missing from 0.2.x tarballs, despite of what is said in the README. -- Nedko Arnaudov <GnuPG KeyID: DE1716B0>

ICE1712 [Envy24] and Master volume

by Stefan Kost

hi, sorry for off-topic post. I have a Hoontech DSP 2000 (Envy24) based soundcard. It works fine with the Envy24 control utility and also to some extend with the gnome-volume-control (gnome-mixer). One annoyance is that there is no master volume. I've routed PCM1/2 to the digital mixer but fail to find any control for digital mixers master volume. Did anyone had more luck with this? Stefan

Vamp plugin SDK v1.1b now available

by Chris Cannam

Version 1.1b of the Vamp plugin SDK is now available. http://www.vamp-plugins.org/ Vamp is a plugin API for audio analysis and feature extraction plugins written in C or C++. Its SDK features an easy-to-use set of C++ classes for plugin and host developers, a reference host implementation, example plugins, and documentation. It is supported across Linux, OS/X and Windows. Version 1.1b is a minor update with a small number of build and bug fixes. The prior version 1.1 of the SDK introduced a new set of classes designed to make it very simple for an application to use Vamp plugins, without needing to do complicated plugin lookup or audio processing themselves. Plugins and hosts remain 100% binary compatible with those built using the 1.0 version of the SDK. Chris
