TimeSide is a set of python components enabling audio analysis, imaging, transcoding and streaming. Its high-level API is designed to enable complex processing on big media data corpus. Its simple plugin architecture can be adapted to various usecases.
It also includes a smart HTML5 interactive user interface embeddable in any web application to provide various media format playback, on the fly transcoding and streaming, fancy waveforms and spectrograms, various low and high level audio analyzers, semantic labelling and segmentation.
We just need a python library to:
- Do asynchronous and fast audio processing with Python,
- Decode audio frames from ANY format into numpy arrays,
- Analyze audio content with some state-of-the-art audio feature extraction libraries,
- Organize, serialize and save analysis metadata through various formats,
- Draw various fancy waveforms, spectrograms and other cool graphers,
- Transcode audio data in various media formats and stream them through web apps,
- Playback and interact on demand through a smart high-level HTML5 extensible player,
- Index, tag and organize semantic metadata (see Telemeta which embed TimeSide).
The streaming architecture of TimeSide relies on 2 main parts: a process engine including various plugin processors written in pure Python and a user interface providing some web based visualization and playback tools in pure HTML5.

Define some processors:
>>> import timeside
>>> decoder = timeside.decoder.FileDecoder('sweep.wav')
>>> grapher = timeside.grapher.Waveform()
>>> analyzer = timeside.analyzer.Level()
>>> encoder = timeside.encoder.VorbisEncoder('sweep.ogg')
then, the magic pipeline:
>>> (decoder | grapher | analyzer | encoder).run()
get the results:
>>> grapher.render(output='waveform.png') >>> print 'Level:', analyzer.results

TimeSide needs some other python modules to run. The following methods explain how to install all dependencies on various Linux based systems.
On Debian, Ubuntu, etc:
$ echo "deb http://debian.parisson.com/debian/ stable main" | sudo tee -a /etc/apt/sources.list
$ sudo apt-get update
$ sudo apt-get install python-timesideOn Fedora and Red-Hat:
$ sudo yum install gcc python python-devel gstreamer pygobject2 \
gstreamer-python gstreamer gstreamer-plugins-bad-free \
gstreamer-plugins-bad-free-extras \
gstreamer-plugins-base gstreamer-plugins-good
$ sudo pip install timesideOtherwise, you can also install all dependencies and then use pip:
$ sudo pip install timeside
python (>=2.7), python-setuptools, python-gst0.10, gstreamer0.10-plugins-good, gstreamer0.10-gnonlin, gstreamer0.10-plugins-ugly, python-aubio, python-yaafe, python-simplejson, python-yaml, python-h5py, python-scipy, python-matplotlib
The TimeSide engine is intended to work on all Unix / Linux platforms. MacOS X and Windows versions will soon be explorated. The player should work on any modern HTML5 enabled browser. Flash is needed for MP3 if the browser doesn't support it.
Of course, TimeSide can be used in any python environment. But, a shell script is also provided to enable preset based and recursive processing through your command line interface:
$ timeside-launch -h
Usage: scripts/timeside-launch [options] -c file.conf file1.wav [file2.wav ...]
