[linux-audio-dev] [ANN] aubio 0.3.0

by Paul Brossier

The latest version of aubio, 0.3.0, is now available. aubio is a library for audio labelling. The goal of this project is to provide automatic feature extraction algorithms to other audio software projects. Features include onset detection, beat tracking, and pitch detection. Functions can be used offline in sound editors and software samplers, or online in audio effects and virtual instruments. This release features several changes: * new pitch detection method, yinfft * new beat tracking algorithm (improved from 0.2.0) * new puredata external * enhancements to the onset detection algorithms * improved aubiocut, can now slice at beats and silences * new aubiopitch python program to extract pitch tracks * plotting features for aubiocut and aubiopitch * python interface refactored * updated documentation As usual, the source code can be found at http://aubio.piem.org/ , and Debian packages are available from http://piem.org/debian/ . Feedback most appreciated! Paul Brossier

[linux-audio-dev] compiler problem?

by Gene Heskett

Greetings; Since I can't get any of the common VoIP things to work due to a lack of duplex function in my lappy's chipset, and my inability to convince the person bugtrack assigned to my bugzilla entry that its not my fault, I thought I'd try zfone next. Unforch, the first step, ./configure, fails with 2 stanza's of this: checking linux/byteorder/little_endian.h usability... no checking linux/byteorder/little_endian.h presence... yes configure: WARNING: linux/byteorder/little_endian.h: present but cannot be compiled configure: WARNING: linux/byteorder/little_endian.h: check for missing prerequisite headers? configure: WARNING: linux/byteorder/little_endian.h: see the Autoconf documentation configure: WARNING: linux/byteorder/little_endian.h: section "Present But Cannot Be Compiled" configure: WARNING: linux/byteorder/little_endian.h: proceeding with the preprocessor's result configure: WARNING: linux/byteorder/little_endian.h: in the future, the compiler will take precedence configure: WARNING: ## ------------------------------------------ ## configure: WARNING: ## Report this to the AC_PACKAGE_NAME lists. ## configure: WARNING: ## ------------------------------------------ ## checking for linux/byteorder/little_endian.h... yes checking linux/byteorder/big_endian.h usability... no checking linux/byteorder/big_endian.h presence... yes configure: WARNING: linux/byteorder/big_endian.h: present but cannot be compiled configure: WARNING: linux/byteorder/big_endian.h: check for missing prerequisite headers? configure: WARNING: linux/byteorder/big_endian.h: see the Autoconf documentation configure: WARNING: linux/byteorder/big_endian.h: section "Present But Cannot Be Compiled" configure: WARNING: linux/byteorder/big_endian.h: proceeding with the preprocessor's result configure: WARNING: linux/byteorder/big_endian.h: in the future, the compiler will take precedence configure: WARNING: ## ------------------------------------------ ## configure: WARNING: ## Report this to the AC_PACKAGE_NAME lists. ## configure: WARNING: ## ------------------------------------------ ## checking for linux/byteorder/big_endian.h... yes I've googled in vain for a solution as the make also fails later: gcc -DHAVE_CONFIG_H -I. -I. -I../config -I../include -I../bnlib/ -I../srtp/include -I../srtp/crypto/include -Wno-unused -g -O2 -c -o base32.o `test -f './base32.c' || echo './'`./base32.c In file included from ../srtp/crypto/include/datatypes.h:60, from ../srtp/crypto/include/err.h:49, from ../srtp/crypto/include/rand_source.h:49, from ../srtp/crypto/include/crypto_kernel.h:49, from ../srtp/include/srtp.h:53, from ../include/zrtp_protocol.h:13, from ../include/zrtp_types.h:184, from ./base32.c:7: /usr/include/netinet/in.h:354: error: expected declaration specifiers or ‘...’ before ‘(’ token /usr/include/netinet/in.h:354: error: expected ‘)’ before ‘?’ token /usr/include/netinet/in.h:355: error: expected declaration specifiers or ‘...’ before ‘(’ token /usr/include/netinet/in.h:355: error: expected ‘)’ before ‘?’ token /usr/include/netinet/in.h:357: error: expected declaration specifiers or ‘...’ before ‘(’ token /usr/include/netinet/in.h:357: error: expected ‘)’ before ‘?’ token /usr/include/netinet/in.h:359: error: expected declaration specifiers or ‘...’ before ‘(’ token /usr/include/netinet/in.h:359: error: expected ‘)’ before ‘?’ token ./base32.c: In function ‘b2a’: ./base32.c:59: warning: comparison of distinct pointer types lacks a cast make[1]: *** [base32.o] Error 1 make[1]: Leaving directory `/usr/src/Zfone/libzrtp-0.2.0/src' make: *** [all-recursive] Error 1 This is after outputting dozens of warnings about 'too many arguments for function' Phil Zimmerman's code is usually of quite high quality... -- Cheers, Gene

[linux-audio-dev] stuff I've done

by Bradford Garton

Hey everyone -- Sorry about the multiple postings, but I figured what the heck... I've just put on-line a whole lot of work I've done; papers, pieces, software, etc. Here's the link for the 2-3 people (beyond my immediate family) who might be interested: http://music.columbia.edu/~brad/ There's a fair amount of unix/linux work scattered throughout, including the big "My Music Book" thing I did a few years ago. Hope you enjoy this! brad

[linux-audio-dev] [ANN] Sonic Visualiser: An application for audio visualisation and analysis

by Chris Cannam

Announcing Sonic Visualiser, an application for viewing and analysing the contents of music audio files. http://www.sonicvisualiser.org/ Sonic Visualiser contains advanced waveform and spectrogram viewers, as well as editors for many sorts of audio annotations. Besides visualisation, it can make and play selections based on the locations of automatically detected features, seamlessly loop playback of single or multiple noncontiguous regions, synthesise annotations for playback, and slow down playback while retaining display synchronisation. Sonic Visualiser also introduces the Vamp plugin API, for plugins that extract descriptive or analytical data from audio. Vamp plugins for onset, pitch and note detection using the Aubio library are available, as well as plugins for tempo tracking, chromagram analysis, constant-Q spectrogram, spectral centroid, power curve and tonal change detection. There is also a comprehensive SDK for use by developers of Vamp plugins and hosts. Sonic Visualiser is Free Software distributed under the GNU General Public License. The 0.9 release is available now in source code form or as binaries for Linux, OS/X, and Windows. For more information and downloads, please see http://www.sonicvisualiser.org/ For more information about Vamp plugins, please see http://www.sonicvisualiser.org/vamp.html See also the SourceForge page for this project at http://www.sourceforge.net/projects/sv1/ Sonic Visualiser was developed at the Centre for Digital Music, Queen Mary, University of London and partially funded by the European Commission through the SIMAC project IST-FP6-507142.

For reference there are alternative ways to gain access to the rlimits functionality which don't rely on updated PAM (or login on PAM-less systems such as Slackware). Set_rlimits, available at http://www.physics.adelaide.edu.au/~jwoithe/set_rlimits-1.2.0.tgz is one alternative and has the advantage of operating on a per-user/per-application level rather than a per-user level (ie: elevated limits are set for users/groups running specified applications only). Yes, it's slightly less convenient but it works and is arguably more secure. Regards jonathan

[linux-audio-dev] [ANN] realtime-lsm 0.8.6 available via SourceForge

by Jack O'Quin

Download links (once SF finishes updating mirrors)... http://prdownloads.sourceforge.net/realtime-lsm/rt-lsm-0.8.6-kernel.patch.g… http://prdownloads.sourceforge.net/realtime-lsm/realtime-lsm-0.8.6.tar.gz?d… The Realtime Linux Security Module (LSM) is a loadable extension for Linux 2.6 kernels. It selectively grants realtime permissions to specific user groups or applications. This release provides the kernel patch formerly included in Andrew Morton's kernel development tree. This module is no longer available there, so I am releasing it for download via SourceForge. The kernel developers prefer their own rlimits solution for granting realtime privileges. Since that is their responsibility, I defer to their feelings. Since their solution requires PAM updates which have been very slow to appear in end-user distributions, I continue to provide this (simpler) solution via SourceForge for those who need it. There are no new features. You need not update, if an older version still works for you. This patch is not actively being developed, but I will continue to provide support as needed for the many users of distributions still lacking the required PAM updates for the rlimits solution preferred by the kernel developers. This release only supports kernel version 2.6.6 and newer. For older kernels, realtime-lsm-0.1.1 is still available. This LSM was written by Torben Hohn and Jack O'Quin, who make no warranty concerning the safety, security or even stability of your system when using it. But, if you do have problems, please report them on the linux-audio-user(a)music.columbia.edu mailing list -- joq

[linux-audio-dev] LV2 Logo again

by Thorsten Wilms

Hi! So LV2 will be the name by benevolent dictator descision :) More work on the logo: http://affenbande.org/~thorwil/wordpress/2006/05/19/lv2-5/ It's still a bit rough, so a few things might not be lined up perfectly, line width may be slightly inconsistent, but it should be good enough to get the idea and judge the overall shapes. I tried to bring in the idea of things connecting to build a whole. A puzzle in a way. I would like to hear of preferences (2 picks are better than 1), dislikes, and pointers to what could be improved with a specific variation. Cheers, Thorsten Wilms
