Convert MP4 to ALAC

MP4 to ALAC Conversion Software converts MP4 files to ALAC (Apple Lossless Audio Codec). With a simple and use-to-use interface, the conversion from MP4 to ALAC is as easy as 1-2-3. You don't need to know professional knowledge of MP4 and ALAC. The converter also support common formats such as AAC, M4R (iPhone ringtone), AWB, AU, AC3, AMR, OGG, VOC, etc. It could convert MP4 to MMF, VOB to AWB, OGG to M4A (MPEG-4 audio), VOB to M4R (iPhone ringtone), AIFC to AU, SWF to MP2, and so on.

The software is very easy to use and supports batch conversion. It is full compatible with 32-bit and 64-bit Windows 10/8/7/Vista/XP/2000.

MP4 to ALAC Conversion Software is compatible with Windows 10/8/7/Vista/XP/2008/2003/2000

What is MP4?
MPEG-4 Part 14, formally ISO/IEC 14496-14:2003, is a multimedia container format standard specified as a part of MPEG-4. It is most commonly used to store digital audio and digital video streams, especially those defined by MPEG, but can also be used to store other data such as subtitles and still images. Like most modern container formats, MPEG-4 Part 14 allows streaming over the Internet. The official filename extension for MPEG-4 Part 14 files is .mp4, thus the container format is often referred to simply as MP4.

MPEG-4 is a patented collection of methods defining compression of audio and visual (AV) digital data. It was introduced in late 1998 and designated a standard for a group of audio and video coding formats and related technology agreed upon by the ISO/IEC Moving Picture Experts Group (MPEG) (ISO/IEC JTC1/SC29/WG11) under the formal standard ISO/IEC 14496 - Coding of audio-visual objects. Uses of MPEG-4 include compression of AV data for web (streaming media) and CD distribution, voice (telephone, videophone) and broadcast television applications.

MPEG-4 absorbs many of the features of MPEG-1 and MPEG-2 and other related standards, adding new features such as (extended) VRML support for 3D rendering, object-oriented composite files (including audio, video and VRML objects), support for externally-specified Digital Rights Management and various types of interactivity. AAC (Advanced Audio Coding) was standardized as an adjunct to MPEG-2 (as Part 7) before MPEG-4 was issued.

MPEG-4 is still a developing standard and is divided into a number of parts. Companies promoting MPEG-4 compatibility do not always clearly state which "part" level compatibility they are referring to. The key parts to be aware of are MPEG-4 part 2 (including Advanced Simple Profile, used by codecs such as DivX, Xvid, Nero Digital and 3ivx and by Quicktime 6) and MPEG-4 part 10 (MPEG-4 AVC/H.264 or Advanced Video Coding, used by the x264 encoder, by Nero Digital AVC, by Quicktime 7, and by high-definition video media like Blu-ray Disc).

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. It is not a variant of AAC, but uses linear prediction similar to other lossless codecs such as FLAC and Shorten. iPod players 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.
