4 Important Things Need to Know Before Converting YouTube to MIDI

#1. What are MIDI music files?

MIDI, short for Musical Instrument Digital Interface, is the most widely used music standard format in the arranger world. It can be called a “computer-understandable music score”.

A piece of complete MIDI music is about 10~100 KB, but it contains dozens of music tracks. Almost all modern music is synthesized using MIDI plus a sound library.

Overall, MIDI does not transmit sound signals, but commands.

#2. Why need to convert YouTube to MIDI?

  • MIDI recordings have high quality, which could sound better than most YouTube digital video and audio files.
  • MIDI files take up much less space than MP3, WAV, MPEG or other YouTube audio and video formats.
  • MIDI files are compatible with different platforms and applicable to various applications.

#3. Can we convert YouTube to MIDI directly?

We tested plenty of MIDI converters, so far, no tools have been found to convert YouTube to MIDI perfectly.  The top answer from Yahoo recommends users to download YouTube to audio formats (MP3, WAV, WMA), and then convert the audio to MIDI free. I couldn’t agree with the idea more, as it’s the best solution I’ve seen.

#4. WAV to MIDI vs. MP3 to MIDI, which one is better?

Format  Suitable for Pros Cons
WAV TV, radio, DVD, Flash for web animations Uncompromised audio quality Occupy huge amounts of memory
MP3 Anything on the Internet

  • Can be recognized and played on any portable media player
Shrink the original quality

You see, whether converting WAV to MIDI or MP3 to MIDI, there are pros and cons. Ultimately it depends on your individual needs and special situations.
