What is MP3 file?

MP3 is short for MPEG-1 Audio Layer-3 and is probably the most popular audio data file format in the world. This compressed audio format was created in early 1990s by Moving Picture Experts Group (MPEG). MP3 file contains a header, metadata, and actual audio data in compressed binary format (most of the file content is audio data).

Header holds information about audio data, including encoding, bitrate, and sampling rate. Metadata include information about audio data and is usually stored in ID3 format, which is widely regarded as standard, and is recognized by most devices and audio players.

MP3 file audio quality

MP3 compression method offers significantly reduced file size (roughly 1/10 the size of original file) and decent sound quality. Sound quality is determined by used compression settings, such as bit rate (constant or variable) or sampling rate. Higher values provide better sound quality at the expense of increased file size. Typical settings are 128 kb/s for bit rate and 44,1 kHz for sampling rate, which generate file of size 1MB for each minute of recording.

What else may cause problems?

There can be more reasons which determine that you are not able to open the MP3 file (apart from the lack of the proper application installed).

First - the MP3 file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the MP3 file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the MP3 file should be solved.

Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the MP3 file has not been completed and it cannot be opened properly).
