 ===AAC Fades===
-Unfortunately, the [[AAC]] format cannot have fades applied to it in a [[Lossless|lossless]] way. Therefore, when applying a fade-in or a fade-out to AAC files the audio will be [[Lossy|lossy]] [[transcoding|transcoded]]. Luckily, lossy transcoding AAC files is far less destructive than other lossy formats such as [[MP3]]s. However, it is still highly recommended to only apply fades to an AAC file that has been cut out of the main AAC file, which can then be merged back with the main AAC file once the fades have been applied. This will minimise the lossy transcoding and keep it to the fade-in and fade-out sections.

 ****Process this ''to-be-faded-out.aac'' file using the fade-out script below.
 *****Open the resulting ''faded-out.aac'' file using another MP3DirectCut instance, select all the audio, copy and paste into the end of the main/original AAC file that is still open in MP3DirectCut. Thus, you've now replaced the original ending audio with the new faded-out audio.
 Making these small cuts, processing the fades, then copying & pasting back in, is the best way to minimise negatively impacting the majority of the audio with lossy transcoding.
