[linux-audio-announce] SSM 0.1.1 & noize farm

by Dave Griffiths

Hello all, I'm releasing a bit of an old version of SpiralSynth Modular, while work continues on the 0.2.0 version on sourceforge. It's got some rather nice features, and I should have released it months ago - but it had a crash bug I only found yesterday... anyway: Main app changes: Back to one window GUI with seperate movable areas Fixed Plugin window events/drawing bug Echo/Delay crash bug fix Less C code in SpiralSynthModular.C (Andy Preston) Ability to load ssm files from command line (Dan Bethell) gcc3.1 fixes + dynamic linking bugfix (Takashi Iwai) configure + make fixes (Takashi Iwai) Plugin changes: LFOPlugin (Andy Preston) MeterPlugin (Andy Preston) StereoMixerPlugin fix (Andy Preston) Scaling fix and name sorting for the LADSPAPlugin (Mike Rawes) Sequencer bugfix for dragging note events Matrix now 64X24 + tweaked GUI Matrix can be controlled by an external clock pulse Matrix copy/paste and transpose functionality (Andy Preston) JackPlugin fixed for recent versions of jack (Takashi Iwai) http://www.pawfal.org/Software/SSM/dload/SpiralSynthModular-0.1.1.tar.gz and if you want the cutting edge it's here: http://sourceforge.net/projects/spiralmodular : noize farm I'd also like to announce the noize farm, an open collection of ssm patches that are shared in the spirit of the GPL: http://groups.yahoo.com/group/noize_farm/ Feel free to download, hack, modify, upload and generally have fun with anything you find there. It's currently hosted at yahoo, which means you have to sign up with them to get access to the files - but we think it's worth the hassle for now. I don't see it as being restricted to just ssm patches either, if you like the idea then you can share anything (linux) audio related - as long as the files are small, and open for all to play with. All the best, Dave : www.pawfal.org :

[linux-audio-announce] sfront 0.85 10/13/02 released

by John Lazzaro

Pick up sfront 0.85 -- 10/13/02 at: http://www.cs.berkeley.edu/~lazzaro/sa/index.html [1] Mac OS X support for real-time MIDI control, using the -cin coremidi control driver. Up to four external MIDI sources are recognized. Virtual sources are ignored; expect virtual source support in a future release. [2] Mac OS X memory locking now works in normal user processes, and is no longer limited to root. ----- All the changes in 0.85 are OS X specific, but thought I'd post this here in case people are curious about OS X porting ... With this release, all of the real-time examples in the sfront distribution run under Mac OS X. Specifically, its now it's possible to use OS X as a Structured Audio softsynth -- I've been running my PowerBook this way with 2ms CoreAudio buffers, with MIDI input from my controller via an Edirol UM-1S USB MIDI interface, and audio output via the headphone jack on the Powerbook, and things work glitch-free. Also, because audio and MIDI are both virtualized under OS X, its possible to run multiple ./sa softsynths in parallel (i.e. from different Terminal windows) and get useable layering ... although in most cases, you'd be better off doing your layering inside a single SA engine. To see the -cin coremidi control driver in action, run the sfront/examples/rtime/linbuzz softsynth, it will find external MIDI sources (up to 4, no virtual source support ...) and use them to drive the SA program in real-time. In the linbuzz example, the pitch wheel (set up to do vibrato) mod wheel (spectral envelope) and channel volume controllers are all active -- you can look at the linbuzz.saol SAOL program to see how they are used. The actual CoreMIDI code is in: sfront/src/lib/csys/coremidi.c The most interesting aspect of this code is that a single AF_UNIX SOCK_DGRAM socketpair pipe (named csysi_readproc_pipepair) is used for communication between an arbitrary number of CoreMIDI readprocs (one for each active source) and the SA sound engine (which runs inside the CoreAudio callback -- the actual main thread sleeps and does nothing). Writing the pipe is blocking (but should rarely block, and never for significant time), but reading the pipe is non-blocking. The semantics of the AF_UNIX SOCK_DGRAM (AF_UNIX is reliable, SOCK_DGRAM guarantees the messages from the CoreMIDI readprocs don't mix) makes it a good choice for doing the multi-source MIDI merge. The actual messages sent in the pipe consists of a preamble to identify the readproc, and the (error-checked for SA semantics) MIDI commands in each MIDIPacket. At this point, the Linux and OS X real-time implementations support all of the same features (audio input, audio output, MIDI In, RTP networking) ... I'm not sure if AudioUnits support makes sense for sfront, I'll probably take a closer look at the issue soon ... ------------------------------------------------------------------------- John Lazzaro -- Research Specialist -- CS Division -- EECS -- UC Berkeley lazzaro [at] cs [dot] berkeley [dot] edu www.cs.berkeley.edu/~lazzaro -------------------------------------------------------------------------

[linux-audio-announce] Announcing initial release of FreqTweak

by Jesse Chappell

Announcing the initial release of FreqTweak (v0.4) http://freqtweak.sourceforge.net FreqTweak is a tool for FFT-based realtime audio spectral manipulation and display. It provides several algorithms for processing audio data in the frequency domain and a highly interactive GUI to manipulate the associated filters for each. It also provides high-resolution spectral displays in the form of scrolling- raster spectragrams and energy vs frequency plots displaying both pre- and post-processed spectra. It currently relies on JACK for low latency audio interconnection and delivery. Thus, it is only supported on Linux. FreqTweak is an extremely addictive audio toy, I have to pry myself away from playing with it so I can work on it! I hope it has value for serious audio work too (sound design, etc). The spectrum analysis is pretty useful in its own right. FreqTweak supports manipulating the spectral filters at several frequency resolutions (64,128,256,512,1024, or 2048 bands) depending on your needs and resources. Overlap and windowing are also selectable. The GUI filter graph manipulators (and analysis plots) have selectable frequency scale types: 1x and 2x linear, and two log scales to help with modulating the musical frequencies. Filters can be linked across multiple channels. The plots are resizable and zoomable (y-axis) to allow precise editing of filter values. The current processing filters are described below in the order audio is processed in the chain. Any or all of the filters can be bypassed. The state of all filters can be stored or loaded as presets. Spectral Analysis -- Multicolor scrolling-raster spectragram, or energy vs. freq line or bar plots... one shows pre-processed, another shows post-processed. EQ -- Your basic multi-band frequency attenuation. But you get an unhealthy number of bands... Pitch Scaling -- This is an interesting application of Sprengler's pitch scaling algorithm (used in Steve Harris' LADSPA plugin). If you keep all the bins at the same scale, it is equivalent to Steve's plugin, but when you start applying different scales per frequency bin, things quickly get weird. Gate -- This is a double filter where a given frequency band is allowed to pass through (unaltered) if the power on that band is between two dB thresholds... otherwise its gain is clamped to 0. Delay -- This lets you delay the audio on a per frequency-bin basis yielding some pretty wild effects (or subtle, if you are careful). A feedback filter controls the feedback of the delay per bin (be careful with this one). This is basically what Native Instrument's Spektral-Delay accomplishes. Granted, I don't have all the automated filter modulations (yet ;). See their website for audio examples of what is possible with this cool effect. Have fun... report bugs...

Sweep 0.5.7 Development Release ------------------------------- Sweep is a sound wave editor, and it is now also generally useful as a flexible recording and playback tool. Inside lives a pesky little virtual stylus called Scrubby who enjoys mixing around in your files. This development release is available as a source tarball at: http://prdownloads.sourceforge.net/sweep/sweep-0.5.7.tar.gz?download This version includes support for Ogg Vorbis import and export, including both variable and average bitrate encoding modes. There are many other user interface updates, including new input controls for sample rates and channels, and question, information and system error dialogs. There is a new Screenshot tour of Sweep, including many screenshots of the new dialogs and general editing. If you haven't seen Sweep lately, be sure to check it out: http://www.metadecks.org/software/sweep/screenshots/ Summary of library dependencies: * GTK+ 1.2 (standard in most distributions) * libsndfile-1.0.x, available from: http://www.zip.com.au/~erikd/libsndfile/ * libtdb, available in many distributions or at: http://www.sourceforge.net/projects/tdb * Ogg Vorbis (libogg and libvorbis 1.0 packages), standard in most distributions and available from: http://www.vorbis.com/ Screenshots: http://www.metadecks.org/software/sweep/screenshots/ Sweep is designed to be intuitive and to give you full control. It includes almost everything you would expect in a sound 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 file support * 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 Help wanted! Sweep needs testing; please report any problems encountered! Urgent development is required in the following areas: ALSA and Jack support, updating of translations and user documentation. (NB. Sweep works fine with ALSA under OSS emulation -- the native ALSA support needs some fixing). Sweep is Free Software, available under the GNU General Public License.
