AudioPack
AudioPack provides components that you can use to build audio players. It can replay CDs and a range of audio files including mp3. For CDs, the components allow you to access the free CD track database at FreeDB. This provides track lists for many thousands of commercial CDs. I have built an audio player and a "PVR" that replay files stored on a local drive or on my media server.
RSAudioFilePlayer
RSRSAudioFilePlayer replays any audio file type for which you have DirectShow filters installed. It offers Play, Pause, Seek and variable rate replay - each of these depends on the capabilities of your filters. It also provides state updates to keep user controls in sync with the state of the player.
RSCDPlayer
RSCDPlayer replays CDs. It will find the CD drives on a machine using either ASPI or SPTI, for newer versions of Windows. It will also open and close the CD drawer. The component provides methods for linking to an RSCddb component, which allows a player to get CD track information from the FreeDB database.
RSCddb
RSCddb provides access to the FreeDB database. This internet database contains track lists for many thousands of CDs, in fact it provides more than one for most CDs, separated into a set of Genres. If you don't find a suitable list under one genre, you can look at the others. If you disagree with an assigned genre, you can change it for your local copy.
The component needs a unique ident which can be derived from the CD using an RSDiskID component or the OnDiskID event of the CDPlayer. The rules for deriving this ident are very strict but RSDiskID and the player pass the test for the most difficult CD tests.
Sadly, the Database was discontinued in March 2019, perhaps it will come back sometime?.
RSCDDatabase
RSCDDatabase provides an sqLite3 database for local storage of lists of track names. You do not need to know SQL to use it, just use its methods which allow creation, editing and deletion of track lists. You can also get a count of the lists in the database and delete the lot if you wish. The component does not require you to have the sqLite dll installed.
RSDiskID
RSDiskID can provide a full specification CD ident or a unique ident for DVDs. There does not appear to be a specification for a DVD ident so I have built this one from the DVD content. You can set the length of the DVD ident between 8 and 24 bytes getting more "more unique" each time. You do not need this component for FreeDB access if you have an RSCDPlayer in your application and FreeDB does not work for DVDs.
