Week 21 2021 Audio Editing

January 25 - 28, 2021

Objective: Editing audio files
Assignment-1: 30 second song.
Details: Using Garage Band, create a 30 second song using the Garage Band loops.

Assignment-2: Three Ringtones or Sound Effects
Details: Using Garage Band, create 3 ringtones at 10 seconds a piece.














Terms to be familiar with the physics behind sound:

1.Wavelength - the length of one cycle in a wave. Changing the wavelength changes the pitch.
2. Amplitude - the height of a wave.  Change the amplitude changes the volume.
3. Frequency- how many cycles/second.  The unit of measurement is Hz.  To determine the frequency of a wave take the length of time for one cycle, ie .002 seconds, and divide it by one cycle: 1/.002 = 500 Hz.  This means that there are 500 cycles per second.
4. Equal Loudness Principle: If the amplitude stays the same but we change the frequency, low and really high frequencies sound quieter than the mid-range frequencies.  Our ears perceive the frequencies to be different volumes even though the volume isn't changing.  The louder the frequencies are played at the more similar the volume will be on all the frequencies.
5. Decibels- we measure the loudness of sound by decibels, dB.  Key decibel levels are:
     40dB- whisper
     60 dB- conversation
     70 dB - busy street
     80 dB- acoustic guitar 1" away
     90 dB- baby crying
     110 dB- Power tools
     130 dB- Rock Concert.
6.  Dynamic Range of Human Hearing: 0 dB-120dB (threshold of human hearing)- 140dB (threshold of pain).
7. Frequency range of human hearing: 20Hz-20,000Hz.  lowest and highest perceived pitch.
8. Temporary Threshold Shift (TTS)- when we are in loud environments our ears protect themselves by temporarily shutting down, so we can't hear as well.  After a couple of hours or days hearing returns to normal, unless the exposure was too long in which case hearing damage becomes permeant.
9. Earwax- our body's natural protection against loud sounds.
