ALAC encoder

A managed wrapper for the Apple Lossless Audio Codec. On Windows, CoreAudioToolbox.dll is required. This encoder is not available on Linux.

As a lossless format, ALAC is comparable to FLAC in compression ratio. It is somewhat less commonly supported than FLAC, although it is well supported on MacOS and iOS. It is also supported natively on Windows 10 and higher.
