TimeSide is a python framework enabling low and high level audio analysis, imaging, transcoding, streaming and labelling. Its high-level API is designed to enable complex processing on very large datasets of any audio or video assets with a plug-in architecture, a secure scalable backend and an extensible dynamic frontend.
- Scaled audio computing
- Pseudo-realtime streaming
- Plugin prototyping
- Audio metadata management and visualization
- Automatic segmentation and labelling synchronized with audio events.
- Do asynchronous and fast audio processing with Python,
- Decode audio frames from any audio or video media format into numpy arrays,
- Analyze audio content with some state-of-the-art audio feature extraction libraries like Aubio, Yaafe and VAMP as well as some pure python processors
- Visualize sounds with various fancy waveforms, spectrograms and other cool graphers,
- Transcode audio data in various media formats and stream them through web apps,
- Serialize feature analysis data through various portable formats,
- Playback and interact on demand through a smart high-level HTML5 extensible player,
- Index, tag and annotate audio archives with semantic metadata (see Telemeta which embed TimeSide).
To fund the project and continue our fast development process, we need your explicit support. So if you use TimeSide in production or even in development, please let us know:
- star or fork the project on GitHub
- tweet something to @parisson_studio or @yomguy
- drop us an email <support@parisson.com>
Thanks for your help!
The streaming architecture of TimeSide relies on 2 main parts: a processing engine including various plugin processors written in pure Python and a user interface providing some web based visualization and playback tools in pure HTML5.
Let's produce a really simple audio analysis of an audio file. First, list all available plugins:
>>> import timeside.core >>> timeside.core.list_processors()
Define some processors:
>>> from timeside.core import get_processor >>> from timeside.core.tools.test_samples import samples >>> wavfile = samples['sweep.wav'] >>> decoder = get_processor('file_decoder')(wavfile) >>> grapher = get_processor('waveform_simple')() >>> analyzer = get_processor('level')() >>> encoder = get_processor('vorbis_encoder')('sweep.ogg')
Then run the magic pipeline:
>>> (decoder | grapher | analyzer | encoder).run()
Render the grapher results:
>>> grapher.render(output='waveform.png')
Show the analyzer results:
Level: {'level.max': AnalyzerResult(...)}
So, in only one pass, the audio file has been decoded, analyzed, graphed and transcoded.
For more extensive examples, please see the full documentation.
0.7.1
- fix django version to 1.6.10 (sync with Telemeta 1.5)
0.7
Code refactoring:
- Create a new module timeside.plugins and move processors therein: timeside.plugins.decoder,analyzer, timeside.plugins.encoder, timeside.plugins.fx
- WARNING: to properly manage the namespace packages structure, the TimeSide main module is now timeside.core and code should now be initialized with import timeside.core
- timeside.plugins is now a namespace package enabling external plugins to be automatically plugged into TimeSide (see for example timeside-diadems). This now makes TimeSide a real plugin host, yeah!
- A dummy timeside plugin will soon be provided for easy development start.
- Move all analyzers developped by the partners of the Diadems project to a new repository: timeside-diadems
- Many fixes for a better processing by Travis-CI
- Add a dox file to test the docker building continously on various distributions

Thanks to Docker, TimeSide is now fully available as a docker image ready to work. The image includes all the necessary applications, modules and volumes to start your project in a few minutes.
First install Git, Docker and docker-compose, then copy these commands in a terminal and hit ENTER:
git clone https://github.com/Parisson/TimeSide.git
cd TimeSide
docker-compose up
That's it! You can now browse the TimeSide API: http://localhost:8000/api/
and the admin: http://localhost:8000/admin (admin/admin)
To process some data by hand, you can also start a python shell session into the sandbox:
docker-compose run app python examples/sandbox/manage.py shell
To build your own audido project on top of TimeSide, just pull our latest master image:
docker pull parisson/timeside:latest
WARNING: our docker composition already bundles some powerfull containers and bleeding edge frameworks (Nginx, MySQL, RabbitMQ, Celery, Python, Django) that can be scaled from development to massive production environments very easily. But you must modify all the passwords and secret keys of the sandbox before any serious usecase.
More infos about the TimeSide docker image: https://registry.hub.docker.com/u/parisson/timeside/
For Debian based distributions, we provide a safe repository giving additional dependencies that are not included in Debian yet. Please follow the instructions on this page.

Of course all the TimeSide are available in our beloved python envionment. As IPython is really great for discovering objects with completion, writing notebooks, we strongly advise to install and use it:
sudo apt-get install ipython
ipython
>>> import timeside
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 ...]
help: scripts/timeside-launch -h

TimeSide comes with a smart and pure HTML5 audio player.
Features: * embed it in any audio web application * stream, playback and download various audio formats on the fly * synchronize sound with text, bitmap and vectorial events * seek through various semantic, analytic and time synced data * fully skinnable with CSS style
Examples of the player embeded in the Telemeta open web audio CMS: * http://parisson.telemeta.org/archives/items/PRS_07_01_03/ * http://archives.crem-cnrs.fr/items/CNRSMH_I_1956_002_001_01/
Development documentation: * https://github.com/Parisson/TimeSide/wiki/Ui-Guide
TODO list: * zoom * layers
An EXPERIMENTAL web server based on Django has been added to the package from version 0.5.5. The goal is to provide a full REST API to TimeSide to enable new kinds of audio processing web services.
A sandbox is provided in timeside/server/sandbox and you can initialize it and test it like this:
cd examples/sandbox
./manage.py syncdb
./manage.py migrate
./manage.py runserver
and browse http://localhost:8000/api/
At the moment, this server is NOT connected to the player using TimeSide alone. Please use Telemeta.
Docker is a great tool for developing and deploying processing environments. We provide a docker image which contains TimeSide and all the necessary packages (nginx, uwsgi, etc) to run it either in development or in production stages.
First, install Docker: https://docs.docker.com/installation/
Then, simply pull the image and run it:
docker pull parisson/timeside
docker run -p 9000:80 parisson/timeside
You can now browse the TimeSide API: http://localhost:9000/api/
or get a shell session:
docker run -ti parisson/timeside bash
To start a new development, it is advised to checkout the dev branch in the container:
cd /opt/TimeSide
git checkout dev
or get our latest-dev image:
docker pull parisson/timeside:latest-dev
More infos: https://registry.hub.docker.com/u/parisson/timeside/
First, install TimeSide (see Install).
Then:
sudo apt-get build-dep python-timeside
sudo apt-get install git
git clone https://github.com/Parisson/TimeSide.git
cd TimeSide
git checkout dev
sudo pip install -e .
echo "export PYTHONPATH=$PYTHONPATH:`pwd`" >> ~/.bashrc
