Chapter 4 : Sound :, Don’t need spoken dialog - Coggle Diagram

- - - - Analogous to structured or vector graphics
      - Device dependent
      - File size is much more compact, much smaller than digitized audio
      - File sound better than digital audio files when played on a high-quality MIDI device
      - It is difficult to playback spoken dialog
      - MIDI does not have consistent playback quality
      - One requires knowledge of music theory in order to run MIDI
    - - Digitized audio is analogous to bitmapped images
      - Device independent
      - File size is larger than MIDI file
      - Digitized audio can do so with ease
      - Digital audio provides consistent playback quality
      - Digital audio does not have this requirement
  - - - Digital audio won’t work because you don’t have enough RAM, hard disk space, CPU processing power, or bandwidth
      - Have a high-quality MIDI sound source
      - Have complete control over the machines on which your program will be delivered so you know that your users will have high-quality MIDI playback software
    - - Don’t have control over the playback hardware
      - Have the computing resources and bandwidth to handle digital files.
      - Need spoken dialog
- - - - It stands for Pulse-Code Modulation. It represents raw analog audio signals in digital form. To convert analog signal into digital signal it has to be recorded at a particular interval. Hence it has sampling rate and bit rate (bits used to represent each sample). It a exact representation of the analog sound and do not involve compression. It is the most common audio format used in CDs and DVDs.
    - - It stands for Waveform Audio File Format. It is just a Windows container for audio formats. That means that a WAV file can contain compressed audio. Most WAV files contain uncompressed audio in PCM format. It is just a wrapper. It is compatible with both Windows and Mac
    - - It stands for Audio Interchange File Format. It was developed by Apple for Mac systems in 1988. Like WAV files, AIFF files can contain multiple kinds of audio. It contain uncompressed audio in PCM format. It is just a wrapper for the PCM encoding. It is compatible with both Windows and Mac.
    - - It stands for MPEG-1 Audio Layer 3. It is most popular audio format for music files. Main aim of MP3 is to remove all those sounds which not hearable or less noticeable by humans ears. Hence making size of music file small. MP3 is like universal format which is compatible almost every device.
    - - It stands for Advanced Audio Coding. The compression algorithm used by AAC is much more complex and advanced than MP3, so when compared a particular audio file in MP3 and AAC formats at the same bitrate, the AAC one will generally have better sound quality. It is the standard audio compression method used by YouTube, Android, iOS, iTunes, and PlayStations.
    - - It stands for Windows Media Audio. It was released in 1999.It was designed to remove some of the flaws of MP3 compression method. In terms of quality it is better than MP3. But is not widely used.
    - - Standing for Flash Video, a file with the .FLV file extension is a file that uses Adobe Flash Player or Adobe Air to transmit video or audio over the internet.
