Throughout this lesson, I've learned that pitch is measured in cyles per second called frequency(HZ) and about measuring how loud a sound is, or in other words, its amplitude. Then there is different types of wavelengths. In one cycle, the space from the fundamental frequency up tward the higher pressure would be called compression, while lower or decreasing pressure space would be called the rare faction. There are simple waveforms that follow a continuous pattern, then there are complex waveforms with a unique ADSR pattern. Attack- time it takes to reach full amplitude. Decay- time taken for a rundown from attack to deignated susatian level. Sustain- duration of a note occuring after the attack and decay/ until the note is released by the musician. Release- amount of time it takes for note to reach silence. Timbre is the harmonic content/ frequency finger print of an instument/voice. The ear consists of the Pinna- outer ear that localizes sound/filters out certain frequencies. From there, sound goes through the external ear canal directly to the Eardrum, which is a small flap of skin that vibrates back and forth, attaching to the Malleus(hammer), Incus(anvil), and Stapes(stirrup), acting as a hydraulic system. This system then leads to the Cochlea- a snail shaped organ in the middle ear with different hair folicles that vibrate to different frequencies, sending different frequencies to the brain. Then I looked over common decible levels and learned the optimum level for mixing would be 85-95 dB SPL. Auditory masking- when our ears hear the loudest sounds near to us (due to evolution) blocking out quieter sounds. Acoustic beats- would be when two or more sounds with slightly different frequencies interact. Psychoacoustics- study of how sounds are perceived by the brain. Phase- waveform position at any given moment. (when a sound is 180 degrees out of phase with another sound, then it cancels out). Sterophonic sound reproducing- is way better than mono(1speaker) and uses 2 speakers to catagorize sound to make it sound more stimulating. We went over most of this material and more in the studio with Chris. I actually got to see him edit audio clips for a commercial using protools. I really got an overview of layering audio, shortening, and editing clips on Pro Tools. Plus, I got to have a better tour of all the equipment that I would be using, such as microphone cords and other plugins. All of this information is a little overwhelming when I first started, but it is my passion afterall and I am more than excited to learn more, and I think Chris will be a great tutor. We already seem to be capable of working fast and efficiently together so I couldn't be happier.
