i urgently need a speaker simulator program for the project. i try searching my intrnet but cannot find much that is good. please someone must have some like anyone have library or source code for it?
You cannot get good sound reproduction without good speakers - and good speakers are inherently large and expensive.
The size is governed by the laws of physics - there's nothing you can do about that.
Does the speaker have to be integral to your project?
Couldn't you just provide a socket for earphones - like most MP3 players...?
