Announcing the release of Sonic Visualiser 1.0pre3, a pre-release for
the soon forthcoming Sonic Visualiser 1.0.
http://www.sonicvisualiser.org/
Sonic Visualiser is an application for viewing and analysing the
contents of music audio files. It 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 time-stretch playback while retaining
display synchronisation.
Sonic Visualiser also makes use of the Vamp plugin API, for plugins that
extract descriptive or analytical data from audio. Vamp is an easy to
use plugin API with a comprehensive and well-commented SDK, and is now
frozen for the Vamp 1.0 release.
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.

http://www.sonicvisualiser.org/
For more information about Vamp plugins, please see
http://www.sonicvisualiser.org/vamp.html

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 and the EASAIER
project IST-FP6-033902.

What does "annotations" mean in this context?

In principle it means pretty much any observation about the contents or
context of the audio. Common examples relevant to the current Sonic
Visualiser might be the locations of beats and bar lines in a
performance with rubato; the extents of a particular structural segment
of the music (the chorus, for example); textual labels such as lyrics
or comments about the music; or symbolic note information like MIDI
that is associated with a particular feature in the audio. SV handles
all of those tolerably well, and has unusually good support for
mingling user annotations with machine-generated annotations from
plugins like beat trackers. It doesn't currently handle contextual
metadata not associated with particular moments in the audio, like
biographical information, collection tags like genre etc which can also
be considered annotations.
As one example of why anyone would be interested in annotating bits of
an audio file by hand, have a look at the musicological tutorial from
the CHARM project at
http://www.charm.rhul.ac.uk/content/svtraining/analysing_recordings.html
(This tutorial uses SV 0.9, and some of the things it does would be
simpler with the 1.0pre version.)
You can also use SV for little jobs like beat slicing (run a beat
detection plugin, click-select beats, export as audio), practising your
Chinese tones by comparing the spectral shape of your voice with the
guys on ChinesePod, slowing down and looping non-contiguous bits of
audio to compare one riff with another version later in the song, etc.

Thanks for the explanation, this is very cool stuff.
Should be useful next time I have to transcribe something with a
particularly baffling rhythm.

Hi Chris,
the screenshots look nice so I treid to build it. Could you maybe look into
fixing the warnings the compiler gives for version 1.0. For me the build fails here:

What exactly are you trying to build here? The code that causes these
errors is not in Sonic Visualiser 1.0pre3. It looks as if you're
trying to build an older Sonic Visualiser together with the newer Vamp
plugin SDK.
The downloads page is not very clear on this point (I hope to find time
to tidy it up tomorrow), but the "Source code" download at the bottom
is for the older 0.9 version, not the current 1.0pre3 (which is
available on the SourceForge downloads page).
