AIFF to M4A : Convert Audio from AIFF (Audio Interchange File Format) to M4A (Advanced Audio Coding)with Audio Transcoder, AIFF2M4A converter, conversion

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.
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, as 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 -- about 10MB for one minute of stereo audio at a sample rate of 44.1k and a bit depth 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.

What is M4A?
Advanced Audio Coding (AAC) is a standardized, lossy compression and encoding scheme for digital audio. Designed to be the successor of the MP3 format, AAC generally achieves better sound quality than MP3 at many bit rates.
AAC's best known use is as the default audio format of Apple's iPhone, iPod, iTunes, and the format used for all iTunes Store audio (with extensions for proprietary digital rights management).
AAC is also the standard audio format for Sony’s PlayStation 3 and is supported by Sony's Playstation Portable, latest generation of Sony Walkman, Sony Ericsson Walkman Phone, Nintendo's Wii (with the Photo Channel 1.1 update installed for Wii consoles purchased before late 2007) and the MPEG-4 video standard.

The first step is to select the files for conversion. Run Audio Transcoder and use the Folder Explorer to browse to the files you want to convert. Then select the file in the File List, drag it to the Drop Zone and drop it there.

Optionally, the program allows you to edit the audio tags of any selected file in the Drop Zone.



Once the files are selected, the next step is to select the output settings.

Select the output settings.

The second step is to select the output settings. To begin, select the folder to save the output file to and choose the action to be executed if the output file already exists - create a new file, overwrite or skip the existing file.



You can also set the program to delete a source file after conversion and preserve the original folder structure, when doing batch conversion.

Finally, you should select the output format and audio quality.



Once the output settings are customized, you go to the final step - conversion.

Convert the audio file(s).

To start the conversion, click Convert. A conversion dialog will appear to show the progress of conversion.



During the conversion, you can change the priority of the process or set an automatic event to be executed when the conversion is over. After the conversion has finished, you can find the files in the output folder you specified.
