⩥ Audio.
Answer: Sound, especially when recorded, transmitted or reproduced
⩥ MIDI.
Answer: Musical Instrument Digital Interface
⩥ Mixing.
Answer: The process of blending all the individual tracks in a recording
to create a version of the song that sounds as good as possible
⩥ Post Production.
Answer: Work done on a recording after a recording has taken place
⩥ TDM.
Answer: Time Division Multiplexing - routes multiple streams of digital
audio data between system components
,⩥ Host-based audio processing.
Answer: Processing done on the computer's CPU without the need for
additional DSP cards. Computer's processing ability.
⩥ D-Control Work Surface.
Answer: Up to 80 faders
⩥ D-Command Work Surface.
Answer: Up to 40 faders
⩥ Sound.
Answer: A variation in the air pressure around us. The result of changes
caused by vibrations that create disturbances in the air or water around
the source.
⩥ Waveform.
Answer: The "shape" of the sound or the shape of the vibration that
produced the sound
⩥ Range of human hearing.
Answer: 20Hz to 20,000Hz
⩥ Frequency.
,Answer: How often the sound pressure variates. Measured in Hertz or
CPS (cycles per second). Creates our perception of pitch. Measurement
of the regularly repeating sine wave. Measured from peak to peak. The
number of times a sound wave repeats itself in one second, moving from
the midpoint of the waveform where the sound begins through the crest
of the wave, where the pressure is greatest, through the midpoint again,
to the trough of the wave, where the pressure is the lightest, and back to
the midpoint.
⩥ Amplitude.
Answer: Intensity of the sound pressure variations. Creates our
perception of the loudness of the sound. Measured in decibels (dB). The
measurement of how far vibration of molecules of air travels; the
distance traveled from the mid point. measured on the vertical plane of
the sine wave. Translated as volume or loudness.
⩥ Decibel.
Answer: A logarithmic unit that is used to describe a ratio of sound
pressure. Measure for amplitude. One-tenth of a Bel. (Alexander
Graham Bell measurement)
⩥ Threshold of hearing.
Answer: 0dB
⩥ Threshold of pain.
, Answer: 120dB
⩥ Analog Audio.
Answer: The continuous electric signal produced by a microphone is an
alternating current with a waveform, frequency and amplitude that
directly corresponds to or is analogous to the original acoustic
information.
⩥ Analog-to-digital conversion (A/D Conversion).
Answer: The process of translating electrical signals to binary data.
Two essential factors: sample rate and bit depth
⩥ Sampling.
Answer: The process of taking discrete measurements of an electrical
signal at various moments in time.
⩥ The Nyquist Theorem.
Answer: In order to produce an accurate representation of a given
frequency of sound, each cycle of the sound's vibration must be sampled
a minimum of two times. Sampling rate of at least 40kHz is required to
capture full-frequency audio.
⩥ Alias tones.
Answer: The false tones produced by low sample rates
