  1. 1.  Hi! I am Mario. This is my fifth assignment for “Introduction and Music Production” at Coursera.org
  2. 2.  Hi! I am Mario. This is my fifth assignment for “Introduction and Music Production” at Coursera.org I will be teaching about “Compare and contrast an algorithmic and convolution reverb. Demonstrate the difference and the important features in both types of reverb.”
  3. 3.  To produce an original sound, a synthesizer uses several units or modules of generation and sound processing to create a basic signal, and then change the settings to get the desired tone.
  4. 4.  We are going to study the usage of the 5 most important synthesis modules:
  5. 5.  We are going to study the usage of the 5 most important synthesis modules:  Oscillator  Filter  Amplifier  Envelope  LFO
  6. 6.  The VCO (Voltage Controlled Oscillator) is an electrical voltage controlled oscillator.
  7. 7.  The VCO (Voltage Controlled Oscillator) is an electrical voltage controlled oscillator. Its purpose is to generate a waveform rich in harmonics to allow effective treatment by filtering section.
  8. 8.  Eachwaveform has a “sound personality”, determined by its harmonic content
  9. 9.  Each waveform has a “sound personality”, determined by its harmonic contentSine Sawtooth Square Triangle
  10. 10.  a sine wave produces a simple clean sound without harmonic
  11. 11.  a sine wave produces a simple clean sound without harmonic the sawtooth signal for its part contains all harmonics of decreasing amplitude and its corespondant is quite soft and copper.
  12. 12.  a sine wave produces a simple clean sound without harmonic the sawtooth signal for its part contains all harmonics of decreasing amplitude and its corespondant is quite soft and copper. the squared signal contains only odd harmonics of decreasing amplitude. The raw sound a little hollow.
  13. 13.  a sine wave produces a simple clean sound without harmonic the sawtooth signal for its part contains all harmonics of decreasing amplitude and its corespondant is quite soft and copper. the squared signal contains only odd harmonics of decreasing amplitude. The raw sound a little hollow. the triangular signal looks like a sine wave rich in harmonics and sound closer to an oboe
  14. 14.  TheVCF (Voltage Controlled Filter) is the filter section of a synthesizer
  15. 15.  The VCF (Voltage Controlled Filter) is the filter section of a synthesizer A Filter is used to remove frequencies from the waveform so as to alter the timbre.
  16. 16.  Themain filter is the Low-Pass Filter (LPF).
  17. 17.  The main filter is the Low-Pass Filter (LPF). Low-Pass Filters allows the lower frequencies to pass through unaffected and filters out (or blocks out) the higher frequencies.
  18. 18.  Another common filter is the High-Pass Filter, it does the opposite of a LPF and allows the higher frequencies to pass through unaffected and filters out (blocks-out) the lower frequencies.
  19. 19.  TheVCA (Voltage Controlled Amplifier) s role is to amplify the signal (preamp) before output to the external amplification.
  20. 20.  Byvarying a voltage input, we can change the amplitude of a signal, making it quieter and louder by supplying a smaller or larger voltage as a control signal.
  21. 21.  AnAmplifier uses an Envelope to control the overall loudness (or amplitude) of the sound over time.
  22. 22.  There are many variations of envelopes available. However, the most common envelope has 4 parameters:
  23. 23.  There are many variations of envelopes available. However, the most common envelope has 4 parameters: • Attack time • Decay time • Sustain level • Release time
  24. 24.  Thereare many variations of envelopes available. However, the most common envelope has 4 parameters: • Attack time • Decay time • Sustain level • Release time This is usually called ADSR Envelope.
  25. 25. A (Attack): Just after pressing a key, the envelope opens fromzero to full. This is controlled by the attack time. An attack timeof zero means that the envelope goes from zero to full instantly.Increasing the Attack time means that it will happen moreslowly.
  26. 26. D (Decay): While the key is still pressed, the envelope drops fromfull to the sustain level. This is controlled by decay time. A decaytime of zero means that the envelope goes from full to sustaininstantly. Increasing the decay time means that this will happenmore slowly.
  27. 27. S (Sustain): While the key is still being pressed, the continuingenvelope just remains at the Sustain level. This is set by sustainlevel.
  28. 28. R (Release): When the key is released, the envelope then dropsfrom the sustain level to zero. This is controlled by Release time. Arelease time of zero means that this will happen instantly.Increasing the Release time means that this will happen moreslowly.
  29. 29.  Tomodulate is to exert control or affect or influence or shape.
  30. 30.  Tomodulate is to exert control or affect or influence or shape. Modulation is used to breathe more life into a sound and make it more expressive.
  31. 31.  Tomodulate is to exert control or affect or influence or shape. Modulation is used to breathe more life into a sound and make it more expressive. A Low Frequency Oscillator (LFO) is a very common modulator
  32. 32.  Basically,an LFO is an oscillator working in a range of subsonic frequencies.
  33. 33.  Basically, an LFO is an oscillator working in a range of subsonic frequencies. It acts directly on the generator.
  34. 34.  Basically, an LFO is an oscillator working in a range of subsonic frequencies. It acts directly on the generator. Several settings can be varied and the effect intensity: speed modulation, frequency, waveform used ...
  35. 35.  Tosimulate a vibrato effect, the LFO is modulating at a certain speed the frequency of the signal from the VCO (Voltage Controlled Oscillator).
  36. 36.  To simulate a vibrato effect, the LFO is modulating at a certain speed the frequency of the signal from the VCO (Voltage Controlled Oscillator). Similarly, a tremolo is obtained by modulating the LFO VCA (Voltage Controlled Amplifier) volume.
  37. 37.  This is my last work for “Introduction to Music Production”, we’ve learnt a lot of things this last weeks, a lot of information, so I tried to present the concepts as clearly as possible.

  39. 39.  Thank you for taking the time to read my lesson I hope I was clear and the work I’ve done could be useful for people without this knowledge
