Acoustic Theory 3 Sound Creation and Manipulation

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.

Square Wave Fundamental pitch + odd harmonics. Sine wave + infinite addition of odd- integer harmonic sine waves. i.e. 1 (Fundamental) , etc. e.g. 10Hz (F) + 30Hz + 50Hz + 70Hz + 90Hz, etc.

Sawtooth Wave Fundamental pitch + all harmonics. Sine wave + infinite addition of all integer harmonic sine waves. i.e. 1 (Fundamental) , etc. e.g. 10Hz (F) + 20Hz + 30Hz + 40Hz + 50Hz + 60Hz, etc.

Noise WhitePinkBrownBlueVioletGrey No fundamental pitch Different noise types consist of different frequency spectrums. E.g. White noise = all frequency bands at same amplitude

Who’s 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 we’ve covered? (sine, sqaure, sawtooth, noise) 3.Why do you think they do / don’t? (How can you tell?) Listening activity

3 Components of a musical tone Pitch (Frequency - Wavelength) Timbre (Harmonic Series) Envelope (Amplitude / Intensity)

Envelopes Attack (time) Decay (time) Sustain (level) Release (time)

Things to remember Envelopes control synthesizer parameters in a Linear fashion (from point A to point B) LFO’s control synth parameters in a Cyclical fashion VS i.e.

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 Logic’s 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.

What’s 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!

1.Load preset: “Tutorial Settings”/Analog Saw Init. 2.Change parameters to look like the patch below. 3.Save as “Blank Template”
