This version adds Multi-Threaded encoding, meaning that each of your CPU threads will encode a file, significantly speeding up the encoding process. For example, if you have a folder with lots of music files and you have an AMD Ryzen 7 2700X CPU which has 16 threads, you’ll be encoding 16 music files at a time! This assuming that the folder contains 16 or more files. If the folder contains less than 16 files, the software will use a number of threads that match the file count. If the folder contains more than 16 files, it will encode 16 files at a time until it finishes.
As of the GUI, being now a Multi-Threaded software means that the GUI will not get locked as it did in previous versions. The stability is way better now.
This new version includes 2 options that will further improve the compression of the FLAC files. These options are:
Exhaustive model search (-e flag in the flac.exe command line)
Exhaustively search LP coeff quantization (-p flag in the flac.exe command line)
By enabling these options in the GUI, you’ll save a few kb per FLAC files but the encoding time will be a little slower. If you don’t mind waiting a few extra seconds or minutes while wanting to save a few more KB, then these options will greatly help.
