Hi!

You must use a library for encoding/decoding MP3!
Best and most popular OpenSource project is LAME. Lame used by a large companies like eHelp.com (developer of RoboHelp and RoboDemo), and in a lot of CD2MP3 Ripper!

It orginaly wrote in C but it have some dll files that you can use in your project.
It have a comman-line tool for encoding/decoding too!

I suggest using Command-Line tool.

Lame MP3 homepage:

http://lame.sourceforge.net/

See Lame MP3 yourself and if you cant using it I will write a simple program for you!

First of all, download mmtools7.exe from swiftsoft and install it. Make sure that delphi can access the dcu files (library paths, tools->options).

then in MMMpReg.pas

change the file as follow :

unit MMMpReg;

"
{$I COMPILER.INC}

{$DEFINE _BLADEENC}

Interface

uses
    DesignIntf,
    DesignEditors;
"


then add "C:\Program Files\Borland\Delphi7\Source\ToolsAPI" (or what it is on your computer) to your library pathes.

create a proxies.pas file containing :
"unit Proxies;

interface

function IsProxyClass(ComponentClass: TClass): Boolean;

implementation

function IsProxyClass(ComponentClass: TClass): Boolean;
begin
  Result := True;
end;

end."

and place it in the source/toolsapi dir, or in the directory you compile blade in.

it should work now.
