MP4 to MP3 Converter

MP4 (MPEG-4 Part 14)

The MMF format was created for mobile devices. These files most often store cell phone ringtones, although sometimes other objects such as graphics and text, as well as audio data can be found in them. Can be created from .WAV or .MID files using Yamaha SMAF Tools. There is no program to convert MP3 directly to MMF yet, so the MP3 file must first be converted to WAVE format (file with the .wav extension).

MP3 (MPEG-1 Audio Layer III)

Popular compression and lossy format with small file size and far from the highest sound quality. The emergence of the MP3 format was made possible by the joint efforts of a development team of almost 40 people who have been working on the project for several years. Compared to lossy files, MP3 songs take up much less disk space thanks to a special algorithm. Other advantages of MP3 include excellent compatibility with various programs and audio devices. Despite the fact that, due to the age of MP3, today it does not shine with compression efficiency, its popularity remains very high due to its versatility - the extension is supported on any operating system, a lot of both standard and specialized multimedia software plays this file format. MP3 files can be created with high or low bit rate, which affects the quality of the resulting file. The principle of compression is to reduce the accuracy of some parts of the sound stream, which is almost indistinguishable to most people's ears.
