Sound

• Sample rate

  The number of samples taken per second, measured in Hertz (Hz)
• Sample duration

  How many seconds of audio the sound file contains
• Sample bit depth

  The number of bits available to store each sample e.g. 16-bit
• Playback quality

  The finished quality of the digital sound file. This is effected by the sample rate and bit-depth. The higher the number the better the quality. The higher the number the larger the file size. CD quality is 44,100 samples per second
• Sound file size

  The overall size of a sound file is found by the following formula: Sample rate x duration (s) x bit depth
