Slide 2 Acoustic Theory 3 Sound Creation and Manipulation Slide 3 Learning Outcomes (Recap) Recall synthesised waveforms with reference to overtones / partials / harmonics. Analyse relevant music to explain and assess various synthesiser waveforms. Apply knowledge of sound envelopes to modify synthesiser functions. Slide 4 Slide 5 Square Wave Fundamental pitch + odd harmonics. Sine wave + infinite addition of odd- integer harmonic sine waves. i.e. 1 (Fundamental) + 3 + 5 + 7 + 9 + 11 + 13, etc. e.g. 10Hz (F) + 30Hz + 50Hz + 70Hz + 90Hz, etc. Slide 6 Sawtooth Wave Fundamental pitch + all harmonics. Sine wave + infinite addition of all integer harmonic sine waves. i.e. 1 (Fundamental) + 2 + 3 + 4 + 5 + 6 + 7 + 8, etc. e.g. 10Hz (F) + 20Hz + 30Hz + 40Hz + 50Hz + 60Hz, etc. Slide 7 Noise WhitePinkBrownBlueVioletGrey No fundamental pitch Different noise types consist of different frequency spectrums. E.g. White noise = all frequency bands at same amplitude Slide 8 Whos got the tunes?! 1.How would you describe the sound in terms of arrangement? (Lead, Bass, Pads, Chords/Poly Synth, FX, etc) 2.Do you think the sound contains any of the waveforms weve covered? (sine, sqaure, sawtooth, noise) 3.Why do you think they do / dont? (How can you tell?) Listening activity Slide 9 3 Components of a musical tone Pitch (Frequency - Wavelength) Timbre (Harmonic Series) Envelope (Amplitude / Intensity) Slide 10 Envelopes Attack (time) Decay (time) Sustain (level) Release (time) Slide 11 Things to remember Envelopes control synthesizer parameters in a Linear fashion (from point A to point B) LFOs control synth parameters in a Cyclical fashion VS i.e. Slide 12 Building for learning Building your own sounds can be a great way to learn about sound creation and synthesis. 1.Create and save a blank template in Logics ES 2 synthesiser to serve as a starting point for sound creation. 2.Pick a synth patch from the selection provided and recreate the sound starting with your blank template. Slide 13 Whats on the menu? House x 2: Organ/Sine Bass & Donk Synth. Electro x 2: Square Lead & Major Bass. Drum n Bass: Unison Saw Bass. Hip Hop: G-Funk Moog Lead. Other x 2: Axel F Synth, Jump Synth. Remember to create the blank template first! Slide 14 1.Load preset: Tutorial Settings/Analog Saw Init. 2.Change parameters to look like the patch below. 3.Save as Blank Template Slide 15 My Portfolio: Copy Page: ES2 https://www.dropbox.com/sh/c8hi9z8qfkzjsd0/AACXBz anwvHTZFJMlP3hmSGYa?dl=0
