3G2 to AIF: Extract Audio from 3G2(3GPP2 Mobile Video) Video to AIF(AIFF/AIFC Apple Audio) with River Past Audio Converter, 3G22AIF converter, conversion

What is 3G2?

The 3rd Generation Partnership Project (3G/3GPP) is a collaboration agreement that was established in December 1998. The 3GPP and 3GPP2 specifications call out specific types of media that can exist in .3gp and .3g2 files.

Once you move a video from cell phone to your PC, the easiest way to play it is to use Apple's QuickTime Player.

In general, if a cell phone record a 3g2 video, it should conform to the 3G2 standard. However, a cell phone may not has the ability to play all variety of 3G2 videos due to limited codec support on the cell. Thus, it is easy to convert a cell phone 3G2 to a video format playable on a computer, but it is not so easy to convert a PC video to a 3G2 which is compatible with your particular brand of cell phone.

To convert from 3G2 video to other formats with River Past software, please have Apple QuickTime installed.

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.

Add File

Click on the "Add File" button on the tool bar. The standard file open dialog appears. Select "3GPP/3GPP2 - Mobile Phone Video (*.3gp;*.3g2)" in its "Files of type" combo box.

Select the file you want to convert and click "Open". The file will be added to the conversion file list.

Note: To convert from 3GPP/3GPP2 files, you must have Apple QuickTime installed.

If you are not able to add the file, please verify your QuickTime installation since we use QuickTime to decode 3G2 video. Try to play the file in QT Player.

If QT Player cannot play the file, you will need to reinstall QuickTime.

Select output format

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.
