A synthesizer is composted of four parts, a oscillator, filters, LFOs and an ASDR envelope. An oscillator is very simply the part of a synthesizer that creates the sound wave that can be outputted. Filters are things that you can put on the synthesizer to change the sound frequencies which will change the sound form overall as the sound wave shape changes. LFOs are similar to filters as they change the sound frequency but more so via sweeps and pulses. Finally an ASDR envelope is just a way to modulate the volume of noise emitted from a synth.
- When you are talking about synthesizers, there are four things that are included in all synths. These are oscillators, filters, LFOs and an ASDR Envelope.
- An oscillator is the part of a synthesizer that makes the sound. It creates a sound wave which can be outputted.
- A filter is important to learn how to use because it works like an equalizer for a synthesizer, as it allows you to increase or decrease certain sound frequencies of the synth.
“Number one, Oscillators; number two, Filters; three, LFOs; and four the ADSR Envelope, also known as the amplitude envelope. Don’t worry if these words don’t make a lot of sense right now, by the end of this video they’re going to be second nature.”
