Overview

AudioFerret is a client-server software system for managing audio files (it could also work with video files) for playback. It is intended to replicate the functions of an old-style distributed jukebox, where multiple locations could request songs which were then queued for play on the main "server" unit audible to everyone in the location, but without any unnecessary limitations (e.g. the old units could only host so many songs, and there was no way to view information about what was being played) and making the best use of now-available tools (e.g. wiki pages for more information).

This project is still under development; I have working clients written in MS Access 97 and Gambas, and a PHP client partly written; the audio server was originally written in Access 97 but I have now written one in Gambas which generally works better (although it needs some fixes and improvements).

SQL

Some significant tidying of the data schema is called for, but it's on low priority at the moment.

Optional SQL

This was eventually going to be part of a subsystem for encouraging legit copies of "pirated" tracks. It isn't necessary in order to make the thing work, but I do plan to continue working with it for the next version. <mysql>CREATE TABLE `Source_Types` ( 

 `id` int(11) NOT NULL,
 `descr` varchar(50) default NULL,
 `islegalcopy` tinyint(1) default NULL,
 PRIMARY KEY  (`id`)

) ENGINE=MyISAM DEFAULT CHARSET=latin1; INSERT INTO `Source_Types` VALUES (1,'CD rip of owned CD',1), 

(2,'CD rip of owned content (other media)',1),
(3,'Skimmed from LP',1),
(4,'Skimmed from 45',1),
(5,'Legal free download',1),
(6,'Public Filesharing',0),
(7,'Copied by 3rd party',0);</mysql>

Discarded SQL

These tables had not been used yet, and I think there's probably a better way to provide this functionality using a hierarchical topic/value tree.

The basic idea was to provide data on everything known about the album -- the names of everyone who worked on it, the studio where it was recorded, dates, etc. so that these could be cross-referenced and other works recorded at the same place, produced by the same person, etc. could also be looked up. <mysql>CREATE TABLE `Locations` (
