ALAC to OGG: Convert Audio from ALAC(Apple Lossless) to OGG(OGG Vorbis Audio) with River Past Audio Converter, ALAC2OGG converter, conversion

What is ALAC?

Apple Lossless (also known as Apple Lossless Encoder, ALE, or Apple Lossless Audio Codec, ALAC) is an audio codec developed by Apple Inc. for lossless data compression of digital music. Apple Lossless data is stored within an MP4 container with the filename extension .m4a. While Apple Lossless has the same file extension as AAC, it is not a variant of AAC, but uses linear prediction similar to other lossless codecs such as FLAC and Shorten.[1] iPods with a dock connector (not the Shuffle) and recent firmware can play Apple Lossless-encoded files. It does not utilize any digital rights management (DRM) scheme, but by the nature of the container, it is thought that DRM can be applied to ALAC much the same way it can with other files in QuickTime containers.

What is OGG?

Ogg Vorbis (sometimes just called Vorbis) is an open source patent-free audio compression format, developed as a replacement for proprietary digital audio encoding formats, such as MP3, VQF, and AAC. Vorbis files (which have an .ogg extension) compress to a smaller size than MP3 files, which reduces bandwidth and storage requirements. According to many reports, Vorbis provides better sound quality than MP3.

To encode OGG Vorbis audio with River Past software, please have either Torbias' OGG DirectShow Filters or Radlight Ogg Media Filters installed.
