Chunkup
=======
Given an audio file, and a tab delimited file, split up audio file into
smaller chunks.
Requirements & Caveats
======================
- Imports pysox, therefore has the same dependencies as pysox, namely:
`Required prerequisite are the development libraries of sox at
version 14.3.x, i.e. the header files and libraries to link against.
Specifically you need sox.h in your include path and libsox.so and
libsox.a in your link path. Pysox will not compile against any sox
version prior to
14.3.0. <https://pypi.python.org/pypi/pysox/0.3.6.alpha>`__
- chunkup will *only* chunk up audio. Any other effects (resampling
etc) should be applied to the audio file before running chunkup.
- At the moment, chunkup will operate fairly blindly. If you give it
start and end times for a chunk that actually lie outside of the
provided audio file, it'll return a bunch of sox errors that look
like:
::
trim: End position is after expected end of audio.
trim: Last 1 position(s) not reached.
Installation
============
::
pip install chunkup
After installing chunkup, the ``chunkup`` command line script should be
added to your path, and should be available from anywhere. Test it out
by opening a new terminal and running
::
chunkup -h
Usage
=====
This usage example pulls down `Episode #20: I Want to Break
Free <http://gimletmedia.com/episode/20-i-want-to-break-free/>`__ of
Reply All. The mp3 is 41.5M. You can get ``replyallcreak.txt`` from
https://github.com/JoFrhwld/chunkup/blob/master/examples/replyallcreak.txt
::
curl -L -o examples/reply_all_podcast.mp3 http://bit.ly/chunkup
mkdir chunks
chunkup examples/reply_all_podcast.mp3 examples/replyallcreak.txt chunks/
Chunk naming
------------
``chunks/`` now contains 104 chunks of speech I annotated, largely to
separate out the three speakers in the first segment. The default naming
conventions of chunks are:
::
[n]-[basename]-[col1]-[col3].wav
Where ``[n]`` is the numeric index of the chunk, ``[basename]`` is the
base name of the original soundfile, ``[col1]`` is the value from column
1 in ``replyallcreak.txt`` (in this case, speaker ID), and ``[col3]`` is
the value from column 3 in ``replyallcreak.txt`` (in this case, the
onset time of the chunk in ss.ms). Available variables for naming chunks
are:
+-------------------+-----------------------------------------------------+
| naming variable | description |
+===================+=====================================================+
| ``[n]`` | chunk number |
+-------------------+-----------------------------------------------------+
| ``[basename]`` | base name of original audio file |
+-------------------+-----------------------------------------------------+
| ``[col0-9]`` | value from any the given column in the chunk file |
+-------------------+-----------------------------------------------------+
Configuration
-------------
You can change the chunk naming convention either at the command line
usig the ``-n`` or ``--naming`` flag.
::
$ chunkup -n [col1]-[n].wav examples/reply_all_podcast.mp3 examples/replyallcreak.txt chunks/
Other config options include
+-----------------------+----------------------------------------------------------------------+
| option | description |
+=======================+======================================================================+
| ``-s``, ``--start`` | Column index (starting with 1) for the start time, in ss.ms format |
+-----------------------+----------------------------------------------------------------------+
| ``-e``, ``--end`` | Column index (starting with 1) for the end time, in ss.ms format |
+-----------------------+----------------------------------------------------------------------+
| ``--header`` | Include if chunk file has a header |
+-----------------------+----------------------------------------------------------------------+
All config options can be defined in a config file and passed to
chunkup.py with the prefix ``+``. A sample config file for this data
would be:
::
--naming
[n]-[basename]-[col1]-[col3].wav
--start
3
--end
4
If saved to config.txt, it could be passed to chunkup.py like so:
::
$ chunkup +config.txt examples/reply_all_podcast.mp3 examples/replyallcreak.txt chunks/
