How to Convert MIDI to WAV: 8 Easy Ways

Have you ever encountered this problem: files with the .midi or .mid extension can only be played on certain specific devices? Why is that? You may need to first understand what MIDI is.

MIDI stands for Musical Instrument Digital Interface. It is not like the audio formats we are familiar with, such as MP3. In fact, it is not an audio file, but just a string of instructions that tells what device can recognize it, which notes to play, when to play, how long each note lasts, the intensity of each note, etc.

It does not contain any audio data, as you can also tell from its extremely small file size. Therefore, it cannot be recognized and played by regular audio devices or players. So what should we do if we want to play MIDI files on these devices? The answer is to convert it into a common audio format, such as WAV.

The conversion from MIDI to WAV requires a suitable audio converter. On Windows, a free option is WonderFox Free HD Video Converter Factory.
