Encoder Options for aiff Files
Here you can select the sample rate to use for the output file. A higher sample rate will result in a better quality output.
This number describes how many bits of resolution each sample has. A higher number means a greater resolution. CD quality audio is 16 bits and is generally enough for most applications.
This selects whether the output file will be Mono or Stereo (one channel or two channels respectively).
Here you can specify how your file should be compressed. Unless you have specific requirements then it is best to leave this set to "Uncompressed".
