[ANN] jack_capture V0.9.19, Snd-ls V0.9.8.17 and Rollendurcmesserzeitsammler V0.0.4

by Kjetil S. Matheussen

Download from: http://old.notam02.no/arkiv/src/?M=D jack_capture ============ jack_capture is a program for recording soundfiles with jack. Its default operation is to capture whatever sound is going out to your speakers into a file. (But it can do a number of other operations as well...) Changes 0.9.17 -> 0.9.19: *Do not accept filename starting with "-" when filename is last argument. *Added the "--filename"/"-fn" option to set filename not as the last argument. Can also contain "-" as first character. *Fixed colors a bit and removed a superfluous linebreak. *Fixed segfault for missing values in commandline. *Manually clear allocated memory instead of using calloc. *Removed buffer-info line when recording to stdout. *Removed printing of "continue recording" when writing the last overruns. *Niceify the disk writing thread to -20 when more than half the buffer is used. *Continously show buffer usage, total number of overruns and whether the disk thread has high priority, in the console. Turn off by using the -hdu option. *Added option -dc to disable console update. (same as "-dm -hdu") *Fancier colors. *Removed "hepp". *Made dB meter the default and replaced the -dB option with the -lm option. *Made the console meter wider to fit the info line at the bottom. Snd-ls ====== Snd-ls is a distribution of Bill Schottstaedt's sound editor SND. (http://ccrma.stanford.edu/software/snd/) Its target is people that don't know scheme very well, and don't want to spend too much time configuring Snd. It can also serve as a quick introduction to Snd and how it can be set up. Snd-ls also serves as base code for the San-Dysth softsynth (http://www.notam02.no/~kjetism/sandysth/) and the Snd-rt music programming language (http://www.notam02.no/arkiv/doc/snd-rt) Changes 0.9.8.16 -> 0.9.8.17: *(read-enable 'positions) has been wrongfully turned off for some time. Bactrace should work again now. (This only affects people using snd-ls for programming.) Rollendurchmesserzeitsammler ============================ The Audio Rollendurchmesserzeitsammler is a conservative garbage collector providing general ways to efficiently allocate and use memory inside a realtime audio thread without having to manually free it later. Changes 0.0.1 -> 0.0.4 * Added support for iterior pointers. (Pointers which points inside middle of allocated memory). Turned out Stalin depended on this, plus that c compiler are free to store pointers in registers and stack however they want, so it's better to be safe. * Fixed header. * Made it packagable. Write make and make install to install library file and header files. * Added the function tar_get_dynamic_roots_for(char *pointer,char **start,char **end). This function requires the source for HBGC: http://www.hpl.hp.com/personal/Hans_Boehm/gc/ * Note that there are ways to increase the execution speed significantly, I just haven't had the time yet, so this update doesn't contain all the changes I wished for.

Rivendell v1.0.0rc2

by Fred Gleason

On behalf of the entire Rivendell development team, I'm pleased to announce the release of Rivendell v1.0.0rc2. Rivendell is a full-featured radio automation system targeted for use in professional broadcast environments. It is available under the GNU General Public License. Changes in this release include (from the NEWS file): *** snip snip *** Changes: AMB-OS AMR-100 Receiver Support. Support has been added for importing the 'Native MP2' format files generated by the Westport Communications AMR-100 satellite receiver used by the AMB-OS system. RDDbCheck Enhancements. Added a check for orphaned database tables to RDDbCheck. Timescaling Fixes. A bug has been fixed that affected the precision of timescaling parameters when applied to long-form programs. Temp File Cleanup. A bug has been fixed that was causing temporary files to be left behind after manually posting audio to a podcast feed. Database Update: This version of Rivendell uses database schema version 159, and will automatically upgrade any earlier versions. To see the current schema version prior to upgrade, see RDAdmin->SystemInfo. As always, be sure to run RDAdmin immediately after upgrading to allow any necessary changes to the database schema to be applied. *** snip snip *** Further information, screenshots and download links are available at: http://www.rivendellaudio.org/ Cheers! |-------------------------------------------------------------------------| | Frederick F.

SLV2 0.6.0

by Dave Robillard

SLV2 is a library to make the use of LV2 plugins as simple as possible for applications. Changes this release: - Reworked API to be more future-proof and support plugin ports of various types (e.g. not just float ala LADSPA). - Various performance improvements (extreme improvements with a recent enough version of redland/librdf) - Support for 'scale points' (e.g. combo box ports) - Support plugins with binaries in locations other than the top level of the plugin bundle - Support for new generic LV2 events (replaces old MIDI) in bundled hosts - Several bug fixes - Other things I forget Upgrading (and, for developers, updating code to the new API) strongly recommended. Source available at http://drobilla.net/software/slv2 Packages for amd64 Debian unstable are available, for details see: http://wiki.drobilla.net/Debian Enjoy, -Dave Robillard

[ANN] jack_capture V0.9.17

by Kjetil S. Matheussen

jack_capture ============ jack_capture is a program for recording soundfiles with jack. It's default operation is to capture whatever sound is going out to your speakers into a file, but it can do a number of other operations as well. Normal URL: http://www.notam02.no/arkiv/src/?M=D Note that the above link doesn't seem to currently work because of something which seems to be www upgrade at Notam. But this link does seem to work for now: http://old.notam02.no/arkiv/src/?M=D 0.9.10 -> 0.9.17: ----------------- *Made sure the process thread won't continue sending data when jack_capture is told to quit. This led to a race conditions when recording too many channels at once (which was 256 channels on my machine). *Added the jack_capture_gui script, based on code by Svend-Erik Kjær Madsen's. *Replaced sh by bash to make it work in ubuntu. *Fixed exact port name match and gen_setformat. Thanks to Gabriel J.L. Beckers for reporting the bugs. *Increased the time the console meter is displayed in red from 50ms to 2000ms. (when the recorded jack value is equal to or higher than 1.0.) *Added the -dBr argument to specify reference level when using the console dB meter. *Added the -mr argument to specify reference level when using the meterbridge meter. *Added peak indicators to the console meter. Code to do so taken from meterbridge by Steve Harris. *Updated --help and README with the new options. *Added option "-mt" to change meterbridge type. Current valid options are vu (default), ppm, dpm, jf or sco. It's not necesarry to specify "-mb" if using "-mt". *Added option "-dB" to get a dB meter for the console meter. *Added examples how to record ogg and mp3 files using the -ws option. *Decreased default buffersize from 60 to 20 seconds. (I even had trouble provocing underruns using a minimal 0.05 seconds long buffer, so 60 seconds was obviously overkill) *Fixed message and error printing to stderr when vu meter is running.
