    Digital Audio, excerpt from the manual for MSP–a digital audio recording program

    Thinking of sound as a weather system—a ‘high pressure front’ that moves into your ear.

    The description of the fundamental principles of sound and the translation to digital audio was clear and also addressed the challenges and solutions of working with digital sound. Re: Robert Moog.

    Its interesting to try and translate the equation description to the actual audio meaning: ie, what do:

    ‘level in decibels = 20 log10(A/A0)’ or

    ‘20 log10 (.5/1) _20(-.3) = -6dB’

    mean experientially.

    Question after reading the Nyquist theorem, how would one use more bits to represent each sample?

    Karma Glue:

    We first browsed through random images on Google Images and came across the band Queen with fused heads. This clearly indicated the idea of a fragmented band that comes together. Step by step might be:
    Pic 1: We copied all of our images from google and began by cutting and pasting the cut out heads of the Queen band members and placing them onto the head’s of the Rolling Stones.
    Pic 2: We created a new document and airbrushed out the prisoner’s head and copied the jail bar. We then copied in a Queen band-member’s head and moved the bar into place. We then repeated this 3 times for the other members, moved them in line with each other and cut the document.
    Pic 3: We re-sized and streamlined the keys and copied and pasted them into the tree. We then copied/pasted and reduced the opacity for the Swami image.
    Pic 4: We cut and pasted Queen band-members’ and Swami’s heads onto the retreat group and painted in beautiful beams of light using the Paintbrush tool.
    Pic 5: Finally, we added the heads to the Queen Mother’s portrait and used the Rubber Stamp and Wand tools.
