Mass Effect 2 Audio File (.AFC)

AFC (Mass Effect Audio File Container) is an audio container format developed by Canadian video game development company BioWare for their Mass Effect science fiction video game series based on the Unreal 3 Engine.
Being a container format, an AFC file can contain one or multiple audio streams. The audio data stored in AFC files may represent either speech, background music and/or sound effects used in the game.
In its essence, an AFC file is just a regular OGG file with audio data encoded as RIFF WAVE via the WaveWorks Interactive Sound Engine (Wwise). The only thing that makes AFC files different from regular OGG files is the file header, which is slightly different.
AFC files usually have a sampling rate of about 32000Hz at a variable bit rate (VBR) ranging from 75 to about 105kbps. There are currently no desktop media players that provide AFC playback natively. However, there is a good number of independently developed AFC conversion tools such as afc2ogg or the Gibbed Mass Effect 3 Audio Extractor, which allow users to easily convert AFC files to OGG and play them back in any OGG-compatible desktop media player.

Audible Audio File (.AA)

AA (Audible Audio) is an audio file format developed by Audible.com used for storing and distributing audio books sold on their website.
The books on Audible.com can be downloaded in different versions and sound qualities, and the AA format is used for the lower quality audiobook versions, contrary to AAX, which is the higher quality alternative to the AA format.
In its essence, the audio data stored in AA files is encoded at low bit rates using either MP3 or AAC encoding. However, what makes AA files different from standard MP3 and AAC files is that they may also contain meta data (such as chapter markers, bookmarks etc.) and that they also utilize copy-protection through a proprietary digital rights management (DRM) technology.
To further ensure that copying AA files is as hard as possible, Adubile.com keeps the exact AA file format specification closed to the public, making it extremely hard for third-party developers to break the DRM encryption and invent tools that allow you to grab the necessary audio data and convert it to a popular open audio format like MP3 for example. Therefore playback of AA files is heavily limited to a narrow set of Audible-ready devices such as the Amazon Kindle or the Apple iPod.
Nevertheless, there are a few clever tricks, such as playing the AA file through Windows Media Player and capturing the stereo output of your sound interface with Audacity in order to grab the audio data and export it to a more convenient audio format that can be played on any portable media player.
