M4AResizer for Windows

M4AResizer reduces the size of M4A AAC files and converts M4A ALAC to M4A AAC.

M4AResizer is designed to reduce the size of M4A AAC (Advanced Audio Coding) and ALAC (Apple Lossless Audio Codec) files by recompressing them with a lower bit rate. It works in batch mode - i.e. whole folders can be converted. For those with thousands of files to convert, you can do the whole bunch at once. It's multithreaded - i.e. fast, because it converts multiple (depending on your CPU core count) files at a time.

Using M4AResizer you can reduce the size of M4A AAC files by two, three, five, or even more times.
