[linux-audio-announce] Sweep 0.8.0 (Milestone 1)

by Conrad Parker

Sat Jan 18 2003 -- Sweep 0.8.0 Released ======================================= Sweep is an audio editor and live playback tool for GNU/Linux, BSD and compatible systems. It supports many music and voice formats including WAV, AIFF, Ogg Vorbis, Speex and MP3, with multichannel editing and LADSPA effects plugins. Inside lives a pesky little virtual stylus called Scrubby who enjoys mixing around in your files. This release is available as a source tarball at: http://prdownloads.sourceforge.net/sweep/sweep-0.8.0.tar.gz?download Latest News ----------- This is the first milestone release for Sweep 1. Please test it thoroughly for both general sample editing and live performance. For more information, see http://www.metadecks.org/ . Sweep has been selected as the killer app of the month for January 2003 by Open Sound System (OSS), developers of the most widely used digital audio architecture for UNIX! (http://www.opensound.com/) New in Sweep 0.8.0: * a new monitoring subsystem for use in DJing and live performance. Users with two sound cards can use headphones for monitoring, to prepare mixes and cue samples without disrupting the main output. * A usability bug was fixed in keyboard playback controls * the Italian translation of the user interface was updated by Yuri Bongiorno. New at metadecks.org: Notes for the tutorial "Using Sweep: Fun with Scrubby" are now available online in HTML, PostScript and PDF formats at: http://www.metadecks.org/software/sweep/tutorials/ This is a brief overview of the tutorial given at linux.conf.au 2003 in Perth, Australia; the real thing is live and very, very loud. Further information ------------------- Screenshots: http://www.metadecks.org/software/sweep/screenshots/ Some interesting audio recordings of Scrubby are at: http://www.metadecks.org/software/sweep/demos.html Sweep is designed to be intuitive and to give you full control. It includes almost everything you would expect in a sample editor, and then some: * precise, vinyl like scrubbing * looped, reverse, and pitch-controlled playback * playback mixing of unlimited independent tracks * looped and reverse recording * internationalisation * multichannel and 32 bit floating point PCM file support * support for Ogg Vorbis, MP3 and Speex compressed audio files * sample rate conversion and channel operations * LADSPA 1.1 effects support * multiple views, discontinuous selections * easy keybindings, mouse wheel zooming * unlimited undo/redo with fully revertible edit history * multithreaded background processing * shaded peak/mean waveform rendering, multiple colour schemes Sweep is Free Software, available under the GNU General Public License.

[linux-audio-announce] [ANN] JACK TimeMachine

by Steve Harris

http://plugin.org.uk/timemachine/ tarball, 100k. Depends on SDL, SDL_image, jack and libsndfile. I used to always keep a minidisc recorder in my studio running in a mode where when you pressed record it wrote the last 10seconds of audio to the disk and then caught up to realtime and kept recroding. The recorder died and haven't been able to replace it, so this is a simple jack app to do the same job. It has the advantage that it never clips and can be wired to any part of the jack graph. I've been using it to record occasional bursts of interesting noise from jack apps feeding back into each other. Usage: ./configure, make, make install, run jack_timemachine. Connect it up with a patchbay app. To start recording click in the window. To stop recording, click in the window. It writes out 32bit float WAV files called tm-<time>.wav, where <time> is the time the recording starts from. The prebuffer time and number of channels are set in a macro, defaults are 10s and 2. It works on my machine, and I'l fix major bugs, but I don't really have time to support another piece of software, so good luck :) If anyone wants to maintain it, feel free. May it preserve many interesting sounds for you, Steve

[linux-audio-announce] [ANN] JACK Rack 1.1.2

by Bob Ham

Hi all, Good job I'm getting a new hard disk soon and will be able to install some other distros to test on :) Just build fixes with this release. There was also a gtk-2.2-only function in there, which has been gtk-2.0-ified. * build fixes for gcc 2.9x from Fernando Pablo Lopez-Lezcano * compiles with gtk 2.0 now (thanks to Fernando again) * builds without lrdf now (thanks to Austin Acton) http://pkl.net/~node/jack-rack.html Bob

[linux-audio-announce] swh-plugins 0.3.5 [bugfix]

by Steve Harris

The were some bugs in 0.3.4 so I'm releasing again. Sorry. * UID clash with flanger and l/c/r delay [serious] - spotted by Bob Ham, thanks * SC4 had the wrong label [mild but anoying] * autoconf script wasn't obeying CFLAGS [mild but anoying] I believe that SC4 and the lookahead limiter might be causing problems with some hosts as they have control outs. If you spot problems with these and think its the host, please contact the author. I know that ecasound and jack-rack handle it fine. - Steve

[linux-audio-announce] [ANN] ecasound 2.2.0 released

by Kai Vehmanen

1. A short summary of changes Support for JACK and LADSPA 1.1 added, more intelligent runtime parameter selection, ECI licence changed from GPL to LGPL, new NetECI client API, ecasound emacs mode added, largefile support, new resample, reverse and typeselect audio objects, new peak amplitude chain operator and new utilities ecalength, ecamonitor and ecasignalview. --- 2. What is ecasound? Ecasound is a software package designed for multitrack audio processing. It can be used for simple tasks like audio playback, recording and format conversions, as well as for multitrack effect processing, mixing, recording and signal recycling. Ecasound supports a wide range of audio inputs, outputs and effect algorithms. Effects and audio objects can be combined in various ways, and their parameters can be controlled by operator objects like oscillators and MIDI-CCs. A versatile console mode user-interface is included in the package. Ecasound is licensed under the GPL. The Ecasound Control Interface (ECI) is licenced under the LGPL. --- 3. Changes since last release Although over a year has passed since the last major stable release, ecasound development work has not stopped. To put things into perspective, a diff between 2.0.0 and 2.2.0 takes about 1.7MB of space. Considering the whole 2.2 codebase is just over 2MB, this is quite a lot! In the future there will hopefully be much more frequent releases. Here's a list of most notable changes: * Intelligent parameter configuration. Instead of one set of default parameters, ecasound lets user specify different parameters for three predefined profiles: real-time, real-time-low-latency and non-real-time. When starting processing, ecasound will automatically select and use most suitable profile for the given configuration. Ecasound will not only consider the types of objects, but also the runtime environment: whether it is possible to lock memory, to use RT-scheduling and so on. * The Ecasound Control Interface is now licensed under LGPL. In addition, the ECI implementations are now standalone, and do not require linking against libecasound and libkvutils. Only thing needed to run ECI apps is to have a working ecasound executable installed. * JACK support added. This is a major new addition as it involved making relatively large changes to the ecasound engine. * Up-to-date support for ALSA-0.9 and LADSPA-1.1. * Effect preset improvements. Support for parametrized presets has been improved. For instance it's now possible to write a wrapper effect preset for a complex ecasound effect or LADSPA plugin, and only publish a subset of original effect's parameters. * The disk i/o buffering subsystem that was introduced in ecasound 2.0 has been integrated more closely to the ecasound engine leading to better performance and reliability. * NetECI API. Ecasound now has a daemon mode that allows multiple clients, using the NetECI protocol, to connect to a running ecasound session. A proof-of-concept client, ecamonitor, is included in the package. It can be used to monitor ecasound session status from a separate console. This is especially useful in combination with ecasound's console mode user interface. The console interface can be used for control and the NetECI monitor client for getting real-time status information. In addition, NetECI can be used with all ECI apps. * Ecasound.el, an emacs ecasound mode and a Lisp ECI implementation. * Largefile support for reading and writing audio files larger than 2GB. * New audio object types: JACK, resample, reverse, typeselect. * New chain operators: peak amplitude monitor * Utilities: ecalength and ecamonitor added, ecasignalview totally rewritten. * New ECI implementations: Lisp, Perl and PHP (the last two are not included in the main ecasound package) Full list of changes is available at <http://www.wakkanet.fi/~kaiv/ecasound/history.html>. --- 4. Interface and configuration file changes * Command line options: 2.2 is backward compatible with 2.0 releases, so old scripts and .ecs files should continue to work. See ecasound(1) for more info. * Ecasound Interactive Mode (EIAM): No changes to the commands available in 2.0 releases. See ecasound-iam(1) for more info. * Library interfaces: Major changes in all library interfaces. Direct use of these libraries is no longer encouraged. The ECI and NetECI APIs are preferred for developing new applications on top of ecasound. * Ecasound Control Interface (ECI): No interface changes. * The ~/.ecasoundrc config file is no longer used. The new location is ~/.ecasound/ecasoundrc. As there's now a separate global configuration file, it is no longer necessary to duplicate all config variables in the user config files. See ecasoundrc(5) for further info. --- 5.

[linux-audio-announce] [ANN] swh-plugins 0.3.4

by Steve Harris

http://plugin.org.uk/releases/0.3.4/ Hods of changes, including: * Bugfixes to GSM sim (Pascal Haakmat) * Bugfixes to FM osc (Pascal Haakmat) * Bugfixes to audio divider (Nathaniel Virgo) * Added another compressor, SC4, stereo, no sidechain * Added lookahead brickwall limiter * Added L/C/R delay (requested by Marek Peteraj) * Added Giant flanger (kind of requested by Patrick Shirkey) * Added DJ Flanger (actually requested by Patrick Shirkey) * Should now compile on FreeBSD * Fixed syntax error in RDF metadata, works with Bob H's jack-rack now I've updated the AUTHORS list, but I've undoubtedly forogtten people, so if youre not in there and should be give me a shout. SC4 is more-or-less like SC3, but has no sidechain and a subtly different algorithm. The sidechain was confusing hosts. The limiter has up to two seconds of lookahead, so can be very gentle. The L/C/R delay might be a bit familiar to Korg Trinity users ;) I haven't used it much bet it seems pretty cool. The giant flanger was a mistake, but I left it in anyway. The DJ flanger hjas controls for LFO period (instead of frequency as you would have in a synth) and you can resync the LFO by clicking a toggled control*. - Steve * This reminds me, there would be a use for a MOMENTARY hint (implying or requiring TOGGLED) in LADSPA, that meant that a control port should only be held high while the UI control was held down, otherise you have to double click reset controls, which is confusing.
