COMPARISON OF MIDI AND DIGITIZED AUDIO

 COMPARISON OF MIDI AND DIGITIZED AUDIO

MIDI was developed so that musicians could connect the synthesizer simultaneously. The MIDI protocol is now widely used as a delivery medium to replace and supplement digitized audio in games and multimedia applications.


Generating sound with a MIDI synthesizer has the following advantages


  • The first advantage is storage space that is used to digitally store sample audio from data files in PCM format (eg .wav files). They are very large. This is especially true for long musical pieces captured in stereo using a high sampling rate.
  • MIDI data files, on the other hand, are much smaller than sample audio files. For example, files that contain high-quality stereo sample audio require about 10 megabytes of data per minute of sound, while a typical MIDI sequence demands less than 10 kilobytes of data per minute of sound because it The MIDI files do not contain sampled audio data, it contains only the instructions that the synthesizer needs to play the sound. These instructions are also in MIDI messages that instruct the synthesizer which sound to use and which note to play and how loud each note should play. The MIDI generated from the actual sound synthesizer is equivalent to structured or vector graphics while the audio in the digitize is equivalent to bitmap images.
  • For computers, a small file size means the PC bandwidth used for spooling this data in sound-generating peripherals.
  • Another advantage of using MIDI is to generate sound that includes that capability. So that the music can be easily edited and the playback speed can be changed. In addition, the pitch or key of the sound can also be changed freely. Digital audio does not have this much facility.
  • MIDI is more flexible than digital audio files. In this, every note of the instrument which is playback can be controlled independently. This feature is not possible in digital audio at all. MIDI files sound better than digital audio files.
  • Because of its small size, MIDI files are embedded in web pages and play faster than their digital counterparts.
  • MIDI files are more compact than digital audio size, and MIDI files are completely independent of their playback quality. MIDI file playback requires less RAM and less Processor power.
  • The quality of MIDI music is pure because all recordings are in electronic form and there is no interference from external media such as air, which degrade the quality of the resulting digital audio file.
  • To work with MIDI, it is important to know the musical score, in addition to knowledge of keyboard notation and audio production.
  • MIDI depends on the audio device ie the Playback will be pure only if the MIDI Playback device is the same as the device used for production. The playback quality of digital audio is the same, that is, digital data is heard a lot, irrespective of the playback system.
