.DP File Extension

A DP file is an audio module created by Delta Packer, a packer for Delta Music modules. The module it contains is compressed, for more efficient sharing and storage. Delta Packer and Delta Music are now obsolete, and thus DP files are uncommon.

Delta Music was a music tracker developed by Barricade Software, a Danish software development group, for use on Amiga computers. Barricade released multiple versions of Delta Music, which users could use to create audio modules.

Sometime after the release of Delta Music 2, Barricade released Delta Packer. This program allowed Delta Music users to compress their audio modules into smaller files. These DP files could be played only with Delta Packer, and not with Delta Music.

Unix Amiga Delitracker Emulator (UADE) can open DP files and play the music they contain.

You can also open DP files with Delta Packer, if you are able to install the program in an Amiga emulator. Delta Packer is available for download here.
