Avid's Peripheral Hardware companies
Digidesign (pro)
M-audio, aquired in 2004 (consumer)
When we hear a sound, what do we actually perceive?
variations of the air pressure
When an object moves one cycle in a back and forth motion what has it created
an auditory event
What do we call the rate of auditory events?
Hertz or cycles per second (CPS)
What is the range of human hearing in Hertz?
20-20,000 Hertz
How do we percieve changes in cycles per seconds?
pitch
Avid's Notation company
Sibelius
waveform
the shape of the cycle of compression and rarefaction
1000 Hertz (abreviation)
1 kilohertz (kHz)
amplitude
the intensity of the wave; the higher the anplitude the greater variation between the
compression and the vacuum of rarefaction.
How is amplitude measured?
decibels (dB)
what does 0 bB represent?
the threshold of hearing
what is the threshold of pain?

how many dB doubles the pressure of the compression?
3
How many dB does it take for a human to perceive the sound as twice as loud?
10 dB
how does a microphone transmitt sound?
alternating electrical current, in the shape of the air pressure's waveform
what must happen to microphone's signal before it can be used in a computer'
it must go through an A to D conversion
what does A to D conversion mean?
analog to digital
what does digital mean?
something that can be represented with numerical digits
