AIF to RA: Convert Audio from AIF(AIFF/AIFC Apple Audio) to RA(RealAudio) with River Past Audio Converter, AIF2RA converter, conversion

What is AIF?

Short for Audio Interchange File Format, a common format for storing and transmitting sampled sound. The format was developed by Apple Computer and is the standard audio format for Macintosh computers. It is also used by Silicon Graphics Incorporated (SGI).

The AIFF format is uncompressed so AIFF files tend to be large. However, there is another format called AIFF-Compressed (AIFF-C or AIFC) that supports compression ratios as high as 6:1.

AIFF files generally end with an .AIF or .IEF extension.

AIFC files generally end with an .AIFC extension.

AIFF and AIFC are standard audio format used on MacOS systems. AIFF is not compressed. AIFC is compressed.

Windows can decodec uncompressed AIFF. However, to decode AIFC, you need to have Apple QuickTime installed.

What is RA?

RealAudio was developed by RealNetworks and supports FM-stereo-quality sound. To hear a Web page that includes a RealAudio sound file, you need a RealAudio player or plug-in, a program that is freely available from a number of places.

More information is available on RealNetwork web site.

To convert other audio formats to RealAudio, you will need River Past RealMedia Booster Pack in addition to your audio software.
