AIL real mode driver (.ADV) is a music/MIDI driver file for DOS. It is associated with IBM Audio Interface Library (AIL), a toolkit by John Miles and Miles Design.

Discussion

AIL was later renamed to Miles Sound System (or maybe it's more like the predecessor?). Miles Sound System was acquired by RAD Game Tools in 1994.

It is unclear what relationship, if any, AIL has to IBM.

There was also an edition of AIL for 32-bit protected mode DOS, not covered by this article. And this doesn't even scratch the surface of what Miles Sound System has evolved into.

One way to use ADV drivers was via MIDPAK, a third-party product which incorporated them. MIDPAK is a relative of DIGPAK (see DIGPAK sound driver).

The source code for one version of AIL was released in 2000.

Identification

ADV files are observed to start in one of two ways:

• Bytes 20 00, then ASCII "Copyright (C) 1991 John Miles", then byte 1a.
• Bytes 2d 00, then ASCII "Copyright (C) 1991,1992 Miles Design, Inc.", then byte 1a.

Software

• [1] → "AIL Version 2" (AIL2.ZIP) - AIL v2.14 (and AIL/32 v1.05), including source code, etc.
• MIDPAK v1.0

Sample files

• BQ1P2.ZIP → *.ADV
• DARKSUN.ZIP → *.ADV
