Sweep 0.5.8 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-0.5.8.tar.gz?download
MP3 import is now supported (via libmad). Minor bugs have been fixed in
rendering of …

There is a new page of audio demos made with Sweep. These demonstrate the
sounds of Scrubby, a tool which allows vinyl-like manipulation of digital
audio:

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 PCM file support
* support for Ogg Vorbis and MP3 compressed audio files
* 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.

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 ...

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 …
[View More]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...

This version includes support for Ogg Vorbis import and export, including
both variable …
[View More]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:

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:

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).
