Wavetable synthesizers are great for producing evolving pads, dynamic strings, and punchy bass sounds. The inventor of wavetable synthesis realized that storing a single cycle of a waveform was more advantageous than generating and processing them on-the-fly. During the digital synth revolution of the late-1970вЂ™s computer memory and processing power were expensive. This rise and fall вЂњloopвЂќ is known as a wave cycle. What you should see is a repeating waveform with a sharp upward rise followed by a vertical drop from its peak. LetвЂ™s break it down: Picture a sawtooth wave. When a key or chord is played the synthesizer uses different methods such as looping or pitch-shifting to make its way from one wave cycle to another, thus producing interesting harmonics. Wavetable synthesis is a method in which a variable number of wave cycles are spread across a wavetable.

In contrast, with a resynthesis synth, you simply upload a sample and allow the software to handle the task of synthesis. With an additive synth, you вЂњmanuallyвЂќ stack your waves and use the synthвЂ™s various parameters to further shape the sound you want. So, letвЂ™s assume you want to recreate an 808-inspired bass patch. In traditional additive synthesis, there is no input sound to recreate.

Both methods use a series of stacked sine waves to generate sound, however, synthesizers that use resynthesis recreate the harmonic structure of an input sound by analyzing its frequencies. Resynthesis is additive synthesis with a twist. Practically speaking, however, most natural sounds would require hundreds of oscillators, making the process of вЂњperfectвЂќ recreation extremely tedious. In theory, any sound heard in nature can be perfectly recreated via additive synthesis. Synthesized sound is generated by stacking multiple sine waves until a harmonic structure is formed.ДЄdditive synthesizers allow you to set the precise frequency and amplitude of each sine wave in the stack. And as the name implies, this method involves adding frequencies rather than subtracting them. What is additive synthesis?ДЄdditive synthesis is a close cousin of subtractive synthesis. Next, filters, envelopes, and other parameters are applied to etch out (subtract) certain frequencies until the desired sound is created.

The oscillatorвЂ™s job is to produce a waveform such as a sawtooth, pulse, triangle, or square. For synthesizers, the oscillator is the source while filters act as the modifier. In the human example, the source is our vocal cords, the modifier is our mouth. To put into simple terms, thereвЂ™s a sound source and a modifier. Subtractive synthesis was the most logical starting point for pioneering synthesizer inventors because, believe it or not, itвЂ™s the exact method humans use when singing, humming, or otherwise vocalizing sound.

WeвЂ™ll start with the granddaddy of them all вЂ“ subtractive synthesis.

The purpose of this article is to help you get a better understanding of the common (and uncommon) methods by which these instruments synthesize their sounds. Since then, there have been hundreds, possibly thousands of hardware and software-based synthesizers to hit the market. The synthesizer revolution started in the 1960вЂ™s with the invention of the Minimoog. Production, Production Techniques What are the different types of synthesis?
