This document describes different digital audio formats. It discusses MIDI data, which stores musical instrument sounds and allows changing instruments without re-recording, but depends on sound quality of playback device and has limited effects. It also discusses audio data, which generates sound similar to original but cannot change instruments without re-recording and has large file sizes requiring powerful computers. Both formats have advantages and disadvantages related to sound quality, file size, effects capabilities, and flexibility.

2. Describe digital audio formats
 Digital Audio
 Digital music is the harmonization of
the sound recording made by
conventional and synthetic sounds
that are stored in the computer
technology-based media.
 Digital format can store large
amounts of data, long term and widely
networked.

3. Describe digital audio formats
 Knowing Types of Data
 Data Audio
 Audio data is a voice that sounded like
the original is issued and recorded
from the device sounds.
 Another advantage is almost all audio
software capable of reading these data
as the original because the audio is a
universal data. These data types differ
with the extension MP3 format as well.
Wav. there are some software that
does not recognize the MP3 format.

4. Describe digital audio formats
 The weakness of this audio data is hard
disk space dibutuhkanya large. One song
that has become (consisting of only one
video data) may require more than 50,000
bytes (50 Mbyte).
 The greater ratenya (mono or stereo), the
hard disk space required will also be
greater.

5. Describe digital audio formats
 MIDI data
 If you play the keyboard with brand A,
stored in MIDI format and play back
degan using computers, the results are
strange and far terdengat so than the
original sound
 With diciptakanya MIDI format, now
how music began to shift. The
musicians do not bother to play every
detail of the music of a song if the
music is already there in the MIDI file.

6. Describe digital audio formats
 MIDI DATA
 Advantages:
 Type of musical instrument can be changed
at will without having to re-record the song
data.
 File size is very small (5-minute songs full
orchestra can only size 50 Kb)
 Does not need a computer that 'powerful'.
 Weaknesses:
 Musical instrument sound quality depends on
the soundcard / MIDI instrument used.
 MIDI effects are available is very limited
such as reverb, chorus and so on.

7. Describe digital audio formats
 AUDIO DATA
 Advantages:
 The sound generated is similar to the original.
 The available audio effects are not limited like reverb,
chorus, delay, pitch shifter, distortion, flanger,
compressor, limiter, EQ, parametric EQ and so on.
 Weaknesses:
 Unable to change the type of musical instrument
without re-recording the song data.
 Large file sizes (1 minute stereo CD quality = 10MB)
 Computer requires a "powerful".
