Digital Audio - Coggle Diagram

- - - - Making digital audio files is fairly straightforward on most computers.
      - Plug a microphone into the microphone jack of your computer.
      - If you want to digitize archived analog source materials—music or sound effects that
      - you have saved on videotape, for example—simply plug the “Line-Out” or “Headphone”
      - jack of the device into the “Line-In” jack on your computer.
      - Then use audio digitizing software such as Audacity1, to do the work.
- - - - The basic sound editing operations that most multimedia producers need are described in the paragraphs that follow:
      - Resampling or Downsampling: If you have recorded and edited your sounds at 16-bit sampling rates but are using lower rates and resolutions in your project, you must resample or downsample the file. Your software will examine the existing digital recording and work through it to reduce the number of samples. This process may save considerable disk space.
      - Fade-ins and Fade-outs: Most programs offer enveloping capability, useful for long sections that you wish to fade in or fade out gradually. This enveloping helps to smooth out the very beginning and the very end of a sound file.
