On my first session I went in on Sept 6 12:00-4:00 or so. I got to meet Donny B (mentor/engineer) for the second time and I also met Jesse also an engineer that works as Donny's assistant. As far as students I met Jaime and Rodolfo both in the early twenties and at different stages in their lessons. Rodolfo is a DJ, Jaime wants to be an artist and producer.
In this chapter I have learned that sound is made possible through vibrations. Vibrations change the air pressure or sound pressure level SPL and basically moves the air molecules back and forth. For example acoustic beats like a drum kit or band playing together. Also learned that atmospheric pressure is the natural air pressure around us at all times and although it shifts/changes we can never feel it. When it comes to waveforms there is Spl and peak to peak amplitude and Rms(basic amplitude) and its measured in decibels aka dbs. We also have the fundamental frequency which is the most present frequency used in a wave form. Donny and I went over all this in the studio and he broke down how we perceive pitches and their relation to frequency. we listened to different freq. and found out that i can actually hear up to 1600hz being that I'm 29. Donny's ear was pretty good because he could still hear 1700hz, not so apparent but still present to his ear. also covered the different types of waveforms(sine,square, triangle, saw). we took a small tour and he showed me the different types of reflection absorption and diffusion surfaces they had up in studio A and the purpose for such placements. it makes a difference to have all the placing in the studio so that some frequencies don't bounce back.
