Synthesis
Many sonic components put together to create a final sound output
Waveform
Periodic voltage that represents sound
Oscillators
Signal generator that generates periodic waveforms (i.e VCO voltage controlled oscillator)
Filter
Removes part of the audio signal (i.e. VCF voltage controlled filter)
Amplifier
Controls amplitude over time (i.e VCA voltage controlled amplifier)
Additive Synthesis
building sounds by summing simple waves (SINE waves)
Fourier's Theorem
Any complex sound can be reduced to Sinusonal components
Subtractive Synthesis
Beginning with a complex wave and removing components that we don't want with a filter.
FM Synthesis
to use one frequency to modulate another
Granular Synthesis
method that operates on a micro-time scale. Samples are not used directly, however, they are split into small pieces around 1-50ms. These pieces are called grains, multiple grains can be layered on one another at multiple speeds and volumes
Low Pass Filter
Cuts high frequencies and allows low frequencies to pass
High Pass Filter
Cuts low frequencies and allows high frequencies to pass
Band Pass Filter
Cuts lows and highs, allowing only mids to pass
Cut Off
Frequency point where the filter begins to attenuate the signal
Slope
Measures the rate of attenuation in decibels per octave
Resonance
amplifications of frequencies near the cut-off point
Noise
Sound containing all frequencies
LFO
Sub-audio low-frequency oscillator
Modulation-Matrix
Part of the synth that allows the user to route controlled signals from various sources to various destinations
Sample & Synth
Replace oscillators with a sample bank
White Noise
equal energy per frequency
Pink Noise
equal energy per musical octave
Sample & Synth
Replace oscillators with a sample bank
Portamento
Continuous glide or glissando from one pitch to another
Ring Modulation
Multiplying the amplitude of two oscillators to create sum and difference tones
Sampling
A sampling is a digital recording of a sound
Key Map
A list of samples and which keys and velocities they are assigned to
Sample Rate
Number of samples per second
High = more memory
Low = less high frequencies
Interpolation
Making a new sample to de-tune pitch
Drop samples to go up in pitch
Formants
Part of a sound that does not shift up in pitch or does at a different rate
Multi-Sampling
Key map that has many samples
Additive Synthesis
Building up sounds from simple components
Usually SINE waves
