Describe digital audio formats

Describe digital audio formats :

v  Digital Audio

v  Digital music is the harmonization of the sound recording made by conventional and synthetic sounds that are stored in the computer technology-based media.

v   Digital format can store large amounts of data, long term and widely networked.

v  Knowing Types of Data

v  Data Audio

v  Audio data is a voice that sounded like the original is issued and recorded from the device sounds.

v  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.

v  The Weakness of the audio data is needed a large hard disk space.. One song that has become (consisting of only one video data) may require more than 50,000 bytes (50 Mbyte).

v  The greater ratenya (mono or stereo), the hard disk space required will also be greater.

v  MIDI data

v  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

v  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.

v  MIDI DATA

v  Advantages:

v  Type of musical instrument can be changed at will without having to re-record the song data.

v  File size is very small (5-minute songs full orchestra can only size 50 Kb)

v  Does not need a computer that 'powerful'.

v  Weaknesses:

v  Musical instrument sound quality depends on the soundcard / MIDI instrument used.

v  MIDI effects are available is very limited such as reverb, chorus and so on.

v  AUDIO DATA

v  Advantages:

v  The sound generated is similar to the original.

v  The available audio effects are not limited like reverb, chorus, delay, pitch shifter, distortion, flanger, compressor, limiter, EQ, parametric EQ and so on.

v  Weaknesses:

v  Unable to change the type of musical instrument without re-recording the song data.

v  Large file sizes (1 minute stereo CD quality = 10MB)

v  Computer requires a "powerful".
