Have you ever wanted to enable an application to access your soundcard or
interact with another application via the soundcard? *Soundflower* is a free
audio system extension that allows applications to pass audio to other
applications. Soundflower emulates the interface of an audio device but
allows any audio application to send and receive audio with no other support
needed. It opens as one of two audio devices (2ch/16ch). For most people and
needs, the 2-channel device is sufficient. If you want an application to
interact with another application via the soundcard, select Soundflower as
the output device in the first application and Soundflower as the input
device within the second application. If an application does not allow you to
specify audio devices, you can make Soundflower the default input or output
device inside the *Sound panel in the System Preferences*, or with the *Audio
MIDI Setup utility application* which is the only slightly tricky part. You
may hear interference at first when you setup an audio channel and if so, the
developers recommend increasing the buffer size of both applications (set
within each application). Note that if more than one application is sending
its output to the same channel, the audio will be mixed. The practical usages
of Soundflower include conducting interviews with both voices. So instead of
recording an interview with Skype and only hearing one voice, Soundflower
allows you to record both voices for a more professional production.
Alternatively, it's useful for routing audio from applications such as iTunes
and Spotify to other applications and devices. Note that this download is for
OS X 10.5.8+. You can also download the OS X 10.4 compatible version (Version
1.4.3).. *Soundflower is a remarkably effective and free audio routing
solution.*.Download *Soundflower 1.6.2.1* in Softonic
