Instead of calling the lame executable use libmp3lame directly. As result, this simplifies the prerequisites for creating voice clips for Archos devices to putting the library in the system's search path (Windows: put libmp3lame.dll in the search path or the same folder RockboxUtility.exe is located in. Linux: install the library using your systems package manager) and configuration. This creates a notable encoding speedup on Windows (around factor 6 on my test setup) and a small speedup on Linux (around factor 1.2). The implemenatation currently has the following limitations: - Only enabled on Windows and Linux. On OS X installing the correct dylib is a bit nontrivial, so using the old command line based method is still in use for now. - The encoder parameters are currently hardcoded to use the same values the build system uses. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@31634 a1c6a512-1295-4272-9138-f99709370657
