Can MIDI Files Be Converted to MP3?

What do you do when you encounter a file that’s in a format your computer or mobile device does not support, like a MIDI? You can either find a program that can open it or use audio converter software to convert it to a format that your equipment recognizes. Can they be converted to Mp3 though?

MIDI files can be converted to MP3 by using an audio converter, which comes in two forms. One is an app or software that you need to download and run before doing any conversion. The other is a browser-accessible program that allows you to convert files online without having to download anything. 

This article discusses what a MIDI file is and how it can be converted to an MP3 file. You’ll also find some free audio converters to try.

MIDI stands for Musical Instrument Digital Interface, a universal language various instruments use to communicate. 

It is a set of instructions that dictates the duration, pitch, velocity, or volume of notes, which ones should be played, and when to an electronic device, such as a music instrument, smartphone, tablet, computer sound card, or software.

The MIDI Association explains that MIDI was invented in 1983 as an industry-standard music technology protocol to synchronize computers, tablets, smartphones, and digital music instruments from different manufacturers. MIDI is simply a way of saving audio information to disk to be played back later.

Producers, educators, and artists like musicians, DJs, and hobbyists use MIDI to create, learn, perform, and share their work.

Lifewire adds that the small size of MIDI files makes them excellent for sharing audio information among similar applications, transferring over low-bandwidth internet connections, and storing it on low-capacity devices.

What MIDI Is Not

If you’re wondering what MIDI is, you probably have also wondered what it is not. Let’s take a closer look at what MIDI is not:

  • It is not music.
  • It is not made up of any sound.
  • It does not contain sampled audio like MP3 files.
  • It is not a digital music file format, but it has its own extension (.MID).
  • Its file size is not as big as a regular audio file.

What Is an Audio Converter?

An audio converter is a tool, such as an app, software, or website, that converts one type of audio file into another. It transforms the format of a MIDI file and adjusts the audio to make it available for playback on a preferred device.

Most converters support standard music formats, including MP3, OGG, WAV, and WMA. Some also extract audio information from video files.

Audio converters are either downloadable or in software form, accessed online from any web browser. Surprisingly, some high-quality ones are completely free. Conversion procedures are similar across formats.

Why Convert?

Why should you convert your MIDI files to MP3? We give you several answers:

  • MP3 is the most popular audio format, as almost all devices worldwide support it. 
  • Players that can playback MIDI files are not common.
  • Your favorite smartphone/tablet music app does not support the format of a new song you downloaded. 
  • Your device cannot identify your MIDI audio, the file won’t play, generating error messages.
  • An audio converter can convert obscure formats into one your device supports.
