AFConvert and Core Audio file conversion
-
Hi
I really need to manually convert some audio formats in my app from
aiff to a low bit-rate mp3 or aac. I have come across afconvert which
is bundled (along with source) with the developer tools but not
included on a standard OS X install.
This is unfortunate because it seems that it does exactly what I need,
so I had the thought to bundle it inside my app package and use it
from there. I realise I could cobble together the core audio
frameworks to do what I want as well but why reinvent the wheel eh?
Are there any best practices when bundling foundation tools? or event
just information about how I might approach the bundling of a command
line tool like this?
Cheers
Dave
PS. I have checked and from the license at the top of the afconvert
sources, it seems that it would be legal to do this.

Just place it in either the Contents/MacOS or Contents/Resources
folder in your bundle & use NSBundle to get its path. It's pretty
simple, actually...

As you ask about good practice, you should note this (from the Code
Signing Release Notes):
Do not put helper applications, plugins, and other separately signed
code into the Resources directory of a bundle. The Resources directory
is directly sealed to the main executable. Put plugins into the Plug-
Ins directory. Put helper tools into the executable directory. Put
helper applications (with their own bundles) into the support directory.
