MO3 is a file format that encapsulates various 'MOD' formats (IT, XM, S3M, MTM, MOD) with an essential feature: compressed samples of MP3 and OGG files. A codec is also incorporated without loss of quality and the entire file structure is compressed as well. With MO3 Encoder you can use any MP3 or OGG encoder that works by command line.
All this and thanks to the MO3 Enconder tool, you can greatly reduce file sizes, keeping practically the same sound quality as the originals. In fact, encoding with MP3 and OGG works best with 16-bit samples, so it is no longer necessary to use 8-bit samples.
You can free download MO3 Encoder 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
