This file describe how to install the TimeSide python package from source.
-1. Install dependencies
-=======================
-
-TimeSide needs some other python modules to run.
-See README for the full dependency list.
-
-The following methods explain how to install all dependencies on a Debian based system
-and espacially on Debian Squeeze 6.0 (stable). Is it now considered you have install this system correctly.
-
-Become root. In a terminal or console, run::
-
- $ su
+INSTALL
+=======
-Write your root password.
-Note : you can paste the full command but without the shell character '$'.
-Then::
+TimeSide needs some other python modules to run. The following methods explain how to install all dependencies on a Debian based system like Debian, Ubuntu, etc.. On Fedora and Red-Hat you might replace 'apt-get by 'yum', on Gentoo by 'emerge', or any other package manager you like::
- $ aptitude update
- $ aptitude install python python-gobject gobject-introspection python-setuptools python-xml python-mutagen \
- python-imaging python-numpy python-scipy python-gst0.10 gstreamer0.10-plugins-base gir1.0-gstreamer-0.10 \
- gstreamer0.10-fluendo-mp3 gstreamer0.10-plugins-good gstreamer0.10-plugins-bad
+ $ sudo apt-get update
+ $ sudo apt-get install python python-pip python-setuptools python-gobject \
+ python-gst0.10 gstreamer0.10-plugins-base gir1.0-gstreamer-0.10 \
+ gstreamer0.10-plugins-good gstreamer0.10-plugins-bad \
+ gobject-introspection
-Add Debian multimedia repository to the apt sources.list and install Gstreamer MP3 modules::
-
- $ echo "deb deb http://www.debian-multimedia.org stable main" | tee -a /etc/apt/sources.list
- $ aptitude update
- $ aptitude install gstreamer0.10-fluendo-mp3 gstreamer0.10-lame
-
-
-2. Install TimeSide
-===================
-
-Go into the module directory and then install::
-
- $ cd timeside
- $ python setup.py install
+ $ sudo pip install timeside
-Or, directly from python package directory::
+To get non-free MP3, MP4 or AAC decoding and encoding features, add Debian Multimedia repository and install the modules::
- $ sudo pip install timeside
+ $ echo "deb http://www.deb-multimedia.org stable main non-free" | sudo tee -a /etc/apt/sources.list
+ $ sudo apt-get update
+ $ apt-get install gstreamer0.10-lame gstreamer0.10-plugins-really-bad
3. Use TimeSide
TimeSide : open and fast web audio components
==============================================
-TimeSide is a set of client and server side components for audio-enabling web sites and applications.
+TimeSide is a set of python components enabling easy audio processing, transcoding, imaging and streaming. Its simple architecture and high-level API have been design to process serial pipelines
-It includes a powerful DHTML-based interactive player, with support for time-marking.
-The server side components provide generic APIs for easy transcoding, metadata embedding,
-sound visualization and audio analysis.
+It includes a powerfull HTM5 interactive player which can be embedded in any web application to provide fancy waveforms, various analyzer results, synced time metadata display during playback and remote indexing.
+
+The engine (server side) is fully written in Python, the player (client side) in HTML, CSS and JavaScript.
News
=====
* bugfixes
-Platforms
-=========
+Dive in
+========
-TimeSide is intended to work on all Unix / Linux platforms.
-MacOS X and Windows versions will soon be explorated.
+Define some processors::
-It is mostly written in Python and JavaScript / CSS / HTML
+ >>> import timeside
+ >>> decoder = timeside.decoder.FileDecoder('source.wav')
+ >>> grapher = timeside.grapher.Waveform()
+ >>> analyzer = timeside.analyzer.MaxLevel()
+ >>> encoder = timeside.encoder.Mp3Encoder('output.mp3')
+then, the *magic* pipeline::
-Install and usage
-==================
+ >>> (decoder | grapher | analyzer | encoder).run()
-See INSTALL.rst
+get the results::
+ >>> grapher.render(output='image.png')
+ >>> print 'Level:', analyzer.result()
-Dependencies
-============
+finally see image.png and play output.mp3 ;)

+=================
-High level process example
-===========================
+TimeSide has emerged in 2010 from the `Telemeta project <http://telemeta.org>`_ which develop a free and open-source web audio CMS.
-For example::
+The time decoder depends on the `GStreamer framework<http://gstreamer.freedesktop.org/>`_.
- >>> import timeside
- >>> decoder = timeside.decoder.FileDecoder('source.wav')
- >>> grapher = timeside.grapher.Waveform()
- >>> analyzer = timeside.analyzer.MaxLevel()
- >>> encoder = timeside.encoder.Mp3Encoder('output.mp3')
- >>> (decoder | grapher | analyzer | encoder).run()
- >>> grapher.render(output='image.png')
- >>> print 'Level:', analyzer.result()

+
+Please use absolute paths. For example::
+
+ $ ts-waveforms /home/$user/music/mp3/ /home/$USER/images/
+
+To change the color scheme or the size of the waveforms, edit the script from the source and change the variables of the GrapherScheme object::
