I wonder if someone can help me. I'm trying to add a reference to the LAME MP3 encoder in my VB.Net (3.5) App. The DLL I'm using (lame_enc.dll v3.98.2) was downloaded from here: http://rarewares.org/mp3-lame-bundle.php When I try to add the DLL reference to my project, I get an error: "A reference to C:\\Lame_Enc.dll could not be added. Please make sure this file is accessible and that it is a valid assembly or COM component" I would just assume this was a corrupt download/similar but... The archive passed an integrity test in WinRAR I tried re-downloading it JIC Next thought - the DLL is b0rked but... I've googled and seen that this is a common issue in vs2005. There are quite a few discussions and none of them seem to have a useful conclusion I've tried the SDK tools "genasm"(3.5) and "TlbExp"(2.0) and both say it's not a valid DLL (As suggested in various threads). So... I've come to the conclusion it's not a COM DLL or (obviously) a .Net one. It is probably intact but I can't reference it directly with VS. Previously when I've added non-.Net DLLs, VS has created an INTEROP Class for me. I'd ideally like to achieve similar with this DLL. Unfortunately, this is about the extent of my ability - Can someone please point me in the right direction for how to use this DLL (or another mechanism to interact with LAME)? Many thanks in advance for any help

Sounds like it's not a .Net DLL. You'll likely need to obtain a wrapper (Jayden's answer seems to be a wrapper).

As an aside, you're probably going to want to get LAME direct from the source.

This article uses a different approach at building a wrapper in VB.NET around lame.exe.

Have a look :

This project (in C# albiet but the same principle must apply for VB.NET) refers to using the Lame_enc.dll. You could try downloading the sample project and see what they are doing compared with you :
