  2. .AIFF • Audio Interchange File Format • A standard digital audio file on the Macintosh and some Windows computers.

  3. .MP3 • A digital audio format popular on the Internet.

  4. .WAV • A .WAV sound file is most often used on the Windows platform. It is also acceptable on the Macintosh. Therefore it is a good choice for cross-platform compatible sound files. • We will use .WAV files for some sounds on our multimedia projects.

  5. QuickTime Sound-Only Movie • The QuickTime format, most often used for digital video, is also an efficient method of digitizing sound. • .MOV files.

  6. Compressed Sound • A sound file that has been altered so that it requires less memory. Compressing a sound always reduces sound quality. • Generally, the higher the compression ratio, the lower the sound quality. • We will not be using compressed sounds in our multimedia project.

  7. Decibels (dB) • Units for measuring sound level differences.

  8. Sound Quality • Determined by • quality of source sound. • quality of analog capture device. • sampling rate when digitized. • sampling resolution when digitized. • compression ratio (if any) when digitized.

  9. Sampling Rate • The number of sampling intervals per second used to capture a sound when it is digitized. • The higher the sampling rate, the higher the quality. • The computer (as well as audio CDs) are capable of sampling at 44,100 cycles a second.

  10. Dynamic Range • Determined by the sampling resolution. • The difference between the loudest sound and the softest sound that can be recorded without distortion. • Eight-bit sounds have a dynamic range of 48 dB • 16-bit sounds have 96 dB. • Human hearing ranges from silence to 120 dB.

  11. Downsampled Sound • A sound that has been converted to a lower sampling rate. • Decreases the memory required to store the sound, but reduces sound quality.

  12. Waveform • A graphic representation of a sound. • The height of the waveform represents the amplitude, or loudness.

  13. Amplify • To adjust the strength or loudness of a sound.

  14. Wavelength (period) • The distance between two successive peaks in a waveform. • The number of wavelength per second is the “frequency.”

  15. Frequency • The number of wave peaks or cycles in one second. • Specified in hertz (Hz) or kilohertz (kHz). • Also know as “Pitch” when applied to our perception of sound.
