## Extracting audio from an Audio CD
While Aaru does not directly support extracting audio from an audio CD image, there are multitudes of software that can. First, if the image is an Aaru Format Image, you have to convert it to a more common format. For example, you can bchunk (https://github.com/extramaster/bchunk) to extract the audio to WAV if you convert the image to CUE.
## Listening to audio from an Aaru Format Image
While Aaru itself isn't able to play any audio, another part of the Aaru Data Preservation Suite can! RedBookPlayer (https://github.com/aaru-dps/RedBookPlayer) was specifically created in order to play audio from Aaru Format Images, which is also the only image format supported by it. Although it isn't fully stable or feature complete yet, the core functionality (and then some) is already present, so it's more than worth the time to look into if you want to listen to the audio on your Aaru Format Images!
## Why do so many recordable CDs have 2-3 errors at the end of the disc?
The simplified answer is that it seems that these sectors aren't actually meant to contain data, and are purely a side effect of burning a recordable CD in the TAO burning mode.
## Caution when dumping a large HDD
As of 5.3, dumping a large HDD as an Aaru Format Image has very significant speed issues, and if you want to bypass this, it's recommended to dump to the QCOW2 image format instead. This image can then be mounted using guestmount on most Linux distributions, and can also be navigated quite easily using 7-zip (https://www.7-zip.org/).
## Extracting files from NTFS/HFS/HFS+/etc. images
Unfortunately, Aaru does not support extracting from several well known filesystems at the moment, some notable ones include NTFS, HFS, and HFS+. In cases like these, if you have an Aaru Format Image, you have to convert it to a more well known image format and use other software to mount and/or navigate it.
