OpenASIO v1.01

Open wrapper for ASIO drivers

(ASIO Technology by Steinberg, http://www.steinberg.net)

Purpose

• The IASIO COM interface used by ASIO drivers has no explicitly declared calling convention for the functions. This has resulted in the interface being unusable from some compilers (i.e. Delphi).
• OpenAsio provides a simple wrapper dll which exposes an interface where this problem has been corrected.

Wrapper

• A Visual C++ 6 dll which declares a new COM interface IOpenASIO which matches the Steinberg IASIO interface but changes the calling convention to __stdcall.
• Some files from the ASIO SDK will be needed to compile the dll. This is available from Steinberg.

Client

• A Delphi import unit (OpenAsio.pas). This requires (and is included in) the Delphi ASIO SDK translation located at http://www.axiworld.be.
• Support for further languages (i.e. non-microsoft C++ compilers) may be added in future.

History

• (v1.01) Reference counting for the IOpenAsio object fixed.
