Convert AIFC to AIFF

AIFC to AIFF Converter converts AIFC files to AIFF. The converter focuses on AIFF file that supports almost all codecs in AIFF specification, for example, pcm 8-bit, pcm 16-bit, pcm 24-bit, pcm 32-bit, pcm 32-bit float, pcm 64-bit float, a-Law, mu-Law, IEEE 754 float, ima4, gsm, dwvw, and so on. The software also supports common file format such as FLAC, AIFF, M4A (MPEG-4 audio), MPA, AAC, AMR, AWB, OGG, etc. It could convert WV to AAC, EAC3 to OGG, EAC3 to MP3, M4R to OGG, ALAC to AWB, AU to MMF, 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.

AIFC to AIFF Converter is compatible with Windows 10/8/7/Vista/XP/2008/2003/2000

What is AIFC?
AIFC stands for Compressed Audio Interchange File. Compressed .AIFF audio file that contains CD-quality audio; similar to a .WAV file, but uses audio compression to reduce file size; may incorporate ULAW, ALAW, or G722 compression; commonly referred to as an AIFF-C file.

AIFF-C is being defined because AIFF does not allow for compressed audio data. AIFF-C adds the ability to store compressed audio data in a standard manner. Naturally, AIFF-C also allows the storage of uncompressed audio data. The "C" in AIFF-C signifies its extension to handle compressed audio data.

The differences between the original AIFF and AIFF-C were kept to a minimum. Applications which currently support AIFF should be easily upgradable to AIFF-C.

The following changes have been made from AIFF:

The FORM identifier was changed from 'AIFF' to 'AIFC'. This distinguishes AIFF-C files from AIFF files. Existing AIFF programs, until they are upgraded, will simply ignore AIFF-C files.
The Common Chunk has been extended to include a compression type ID and a compression type name. AIFF-C is thus capable of storing compressed audio data generated from any compression algorithms.
The Sound Data Chunk can contain compressed audio data. The Chunk format has not been modified.
The Sound Accelerator (Saxel) Chunk is new. It is designed to eliminate initial artifacts caused by the de-compression algorithms when playback begins at a random point defined by a Marker.
The Format Version Chunk is new. This Chunk is designed to provide a smooth transition for potential future upgrades to the AIFF-C specification.

What is AIFF?
Audio Interchange File Format (AIFF) is an audio file format standard used for storing sound data for personal computers and other electronic audio devices. The format was co-developed by Apple Computer in 1988 based on Electronic Arts' Interchange File Format (IFF, widely used on Amiga systems) and is most commonly used on Apple Macintosh computer systems. AIFF is also used by Silicon Graphics Incorporated. The audio data in a standard AIFF file is uncompressed big-endian pulse-code modulation (PCM). There is also a compressed variant of AIFF known as AIFF-C or AIFC, with various defined compression codecs.

Standard AIFF is a leading format (along with SDII and WAV) used by professional-level audio and video applications, and unlike the better-known lossy MP3 format, it is non-compressed (which aids rapid streaming of multiple audio files from disk to the application), and lossless. Like any non-compressed, lossless format, it uses much more disk space than MP3¡ªabout 10MB for one minute of stereo audio at a sample rate of 44.1 kHz and a sample size of 16 bits. In addition to audio data, AIFF can include loop point data and the musical note of a sample, for use by hardware samplers and musical applications.

The file extension for the standard AIFF format is .aiff or .aif. For the compressed variants it is supposed to be .aifc, but .aiff or .aif are accepted as well by audio applications supporting the format.
