  • Audio Interchange File Format

    • A standard digital audio file on the Macintosh and some Windows computers.

Slide3 l.jpg

  • A digital audio format popular on the Internet.

Slide4 l.jpg

  • 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.

QuickTime Sound-Only Movie

  • The QuickTime format, most often used for digital video, is also an efficient method of digitizing sound.

    • .MOV files.

Compressed sound l.jpg
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.

Decibels db l.jpg
Decibels (dB)

  • Units for measuring sound level differences.

Sound quality l.jpg
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.

Sampling rate l.jpg
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.

Dynamic range l.jpg
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.

Downsampled sound l.jpg
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.

Waveform l.jpg

  • A graphic representation of a sound.

    • The height of the waveform represents the amplitude, or loudness.

Amplify l.jpg

  • To adjust the strength or loudness of a sound.

Wavelength period l.jpg
Wavelength (period)

  • The distance between two successive peaks in a waveform.

    • The number of wavelength per second is the “frequency.”

Frequency l.jpg

  • 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.
