Several audio file formats exist for storing digital recordings. The most commonly used are MP3, wave (.wav), AIFF (.aif), AAC and WMA. WAV files contain raw audio data and can be quite large. MP3 files use compression to reduce the size of the file without noticeable degradation in sound quality. WMA (Windows Media Audio), developed by Microsoft, is another compression format. AAC (Advanced Audio Coding) is an audio compression format frequently used in Apple products such as iTunes, iPod, and QuickTime. AIFF (Audio Interchange File Format) is a non-compressed audio file format commonly used on Macintosh computers. Audio CDs also store audio recordings.

MIDI (Musical Instrument Digital Interface) files are fundamentally different from audio files. Audio files are the computer equivalent of recording on tape and capture all the elements of the original performance, including the singer’s voice, percussion, and specific instruments. MIDI files do not contain any actual sounds. They merely specify what notes are to be played and when, at a certain loudness level. The sounds you hear when playing back a MIDI file are generated by your computer’s sound card. As a result, the same MIDI file will sound different from one computer to another according to the sound card. Also, MIDI files cannot recreate sung or spoken words or non-musical sounds.

In spite of these limitations, MIDI files have several advantages over audio files. For one thing, they are very compact, smaller even than compressed MP3, WMA and AAC files. But most importantly, you can do things with MIDI files that are impossible with audio files. Using a MIDI notation program (such as Anvil Studio which is included with intelliScore MP3 to MIDI converter), you can see the notes that are present in the music."; function tShowHide(id, show) { var s = document.getElementById("desc"); if ((s.innerHTML.length<=212 || show==1) && show!=2) { s.innerHTML = fDesc[id]; if (document.getElementById('m1')) document.getElementById('m1').style.display='none'; if (document.getElementById('m2')) document.getElementById('m2').style.display='none'; if (document.getElementById('more_txt')) document.getElementById('more_txt').style.display='inline'; } else { s.innerHTML = ''; } }
