A PulseAudio based podcasting application

Thanks to Harry Karvonen for his Python ctypes-based bindings for PulseAudio. Thanks also to Jürgen Geuter for helping me understand distutils and contributing some fixes.

Instructions

If you are looking at the source, 'cd' to the top of this project and then run the following command to try it out:

$ cd pulsecaster
$ python ui.py

Advanced Tips

The code currently contains a very hacky function to allow you to record to FLAC (the Free Lossless Audio Codec) instead of Ogg Vorbis, which is the default. To turn that capability on, run this command:

$ gconftool-2 --set --type=string /apps/PulseCaster/codec flac

To switch back to Vorbis:

$ gconftool-2 --set --type=string /apps/PulseCaster/codec vorbis

There's an additional function for setting audio rate (default is 48000 Hz):

$ gconftool-2 --set --type=int /apps/PulseCaster/audiorate 44100
$ gconftool-2 --set --type=int /apps/PulseCaster/audiorate 48000

Installing

The easiest way to use this application is to simply install it using your platform's preferred tool set. To install it using Fedora, run the folowing command:

pkcon install pulsecaster

To install it on another flavor of Linux, check the documentation for your particular distribution.

To install directly from this source code, use the handy "distutils" script that's provided:

$ python setup.py build
$ python setup.py install

Refer to the wiki at http://pulsecaster.org/ for a full list of dependencies and requirements.

GStreamer

The pipeline for capturing from a running PulseAudio source:

gst-launch pulsesrc device-name='<NAME>' \
   ! vorbisenc quality=0.5 \
   ! oggmux \
   ! filesink location=foo.ogg
