Sampling Intervals and Sample Rate

  • Sampling sound is the process of converting an sound wave into a signal.
  • When sampling sound, the computer takes of the sound wave at regular .
  • The sampling interval is the number of between two samples.
  • The larger the sampling interval, the the quality and file size of the the sound file.
  • The is the number of samples in one second. It is measured in .
  • A sample interval leads to a low sample rate.

Bit Depth and Bit Rate

  • The Bit Depth is the number of used to store one sample into binary.
  • A high bit depth leads to a better sound file.
  • The Bit Rate is the number of bits used per seconds, measured in .
  • A high bit rate leads to a better qaulity sound file.
