AF Format is Sonic Blasters own filetype. This is the default format for saving files. You’ll save the file you want to use as your startup sound in this format.

AIFF Format is the Apple Standard format.

2 : 1 C o m p r e s s e d is a format which does some squeezing to save the same amount of information in half the space.

2 . 6 7 : 1 C o m p r e s s e d same as above but compacting even more. This difference between 2:1 and 2.67:1 will be most noticeable on very large files.

The most noticeable difference between a compressed files and a non-compressed file is the amount of space it takes to store the file. Another difference is that the fidelity may be slightly decreased by the compression. The quality loss is very slight, especially in the case of voice recordings. Try saving a file in both the compressed formats and compare disk space used and quality with the original.

Raw Data is a mono file saved in straight binary format. This means that information, such as the speed at which the file was recorded, is not saved in this format. If you’re saving a file recorded in stereo as raw data, the two channels will be combined into one channel and saved as a mono file. When raw data files are loaded, the playback rate is set to the default setting of 22085 Hz.

*Note: If you plan to use a program or desk accessory that plays back sound files, other than the ones provided with the Sonic Blaster, you’ll need to find Out the program’s or desk accessory’s default playback rate (if it does not let you set the playback rate) and record your sound files at that speed before saving as Raw Data.

Try saving the same file in the different formats and then play them back and check the amount of memory used to determine if you can tell a difference.
