Mp3tag v3.15 and v3.16 released

Mp3tag v3.15 released

I've just released Mp3tag v3.15 and wanted to outline some of the new features and changes:

Support for 64-bit

Mp3tag now comes in two versions, the existing 32-bit and a new 64-bit version. To make it short, there should not be any noticeable differences except for two things:

  • The 64-bit version uses 64-bits to address memory and is no longer limited to 2 GB per application. While the Library feature of Mp3tag is already a very viable solution for large libraries, loosening the memory restriction is one of the key benefits of 64-bit.

  • The 64-bit version has no support for TAK. TAK is a closed-source codec that is made available in Mp3tag by utilizing a DLL. This DLL is unfortunately only provided as 32-bit version at the moment and 64-bit processes cannot load 32-bit DLLs. But I’ve heard a 64-bit version is in the makings, so I'll add support when it's available. Edit: Mp3tag v3.17 now also contains a 64-bit version of TAK.

Mp3tag 64-bit can only be installed on 64-bit versions of Windows. The recommended path is to uninstall the 32-bit version before upgrading — the uninstaller has an option to keep your configuration settings, but please backup your configuration settings via File → Save configuration anyway.

Management of Filter Expressions

I’ve added an option to manage the list of filter expressions via the Manage history… item of the Filter Helper menu. This also allows for named filters, favorite filters for quick access, and the possibility to add descriptions for filters.

Management of Format Strings

Similar to the filter expressions, I’ve added an option to manage the list of format strings at converters Tag - Filename, Filename - Tag, Text file - Tag, and Tag - Tag via the Manage history item of the Format String Helper menu. It also allows for named format strings, favorite format strings for quick access, and the possibility to add descriptions for format strings.
