FLAC to AIF: Convert Audio from FLAC(Free Lossless Audio Codec) to AIF(AIFF/AIFC Apple Audio) with River Past Audio Converter, FLAC2AIF converter, conversion

What is FLAC?

FLAC stands for Free Lossless Audio Codec, an audio format similar to MP3, but lossless, meaning that audio is compressed in FLAC without any loss in quality. This is similar to how Zip works, except with FLAC you will get much better compression because it is designed specifically for audio.

FLAC is a free lossless audio format. It differs from MP3, WMA, MP4 and other formats with lossy compression because it does not cause quality loss. However, the compression ratio is lower.

To convert FLAC audio to other formats with River Past software, you will need to install either CoreFlac or DC-Bass Decoder.

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.

To encode AIF audio, please make sure Apple QuickTime is installed.

Use the setting panel on the bottom of the window to control the output format. Click on the toggle to the left of the "Format" label to expand the panel. Select "AIF - Audio Interchanged File Format" as the "Audio Type".

Troubleshoot

If you don't see the AIF output option, you have a problem with your QuickTime installation.

You need to have the latest QuickTime installed. Occasionally, QuickTime may be corrupted. In any case, reinstall QuickTime should fix this problem.

You can change the compressor, and depending on the compressor, you can change the sample rate, channel (stereo or mono), bits/sample, and bitrate.

When "16 bit LPCM" or "16 bit PCM" is selected as the "Compressor", the file is uncompressed, and satisfy the original AIFF specification. When other compressors are used, the file is compressed and is considered to be an AIFC file.
