BandPassBWFilter.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like BandPassBWFilter.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like drvinst.exe - to follow. These files were created so that multiple programs (eg. AV Voice Changer Software Diamond) could share the same BandPassBWFilter.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.
Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when BandPassBWFilter.dll is attempted to be loaded either when AV Voice Changer Software Diamond is starting up, or in some cases already running. Some of the most common BandPassBWFilter.dll errors include:
- Access Violation at address - BandPassBWFilter.dll.
- BandPassBWFilter.dll could not be found.
- Cannot find C:\Program Files (x86)\AV Voice Changer 9.5 Diamond\Effects\BandPassBWFilter.dll.
- Cannot register BandPassBWFilter.dll.

- The application has failed to start because BandPassBWFilter.dll was not found.
- The file BandPassBWFilter.dll is missing or corrupt.
- This application failed to start because BandPassBWFilter.dll was not found. Re-installing the application may fix this problem.
Your BandPassBWFilter.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with AV Voice Changer Software Diamond), or deleted by a malware infection. Furthermore, BandPassBWFilter.dll file corruption could be caused from a power outage when loading AV Voice Changer Software Diamond, system crash while loading BandPassBWFilter.dll, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.
