I am going to explain the basic concepts of subtractive synthesis and the terminology of subtractive synthesisers with reference to acoustic principles.

Envolves

An envolope is a tool that helps us automate aspects of a sound, It generates a slow and evolving waveform which can be used modulate different parameters of the synthesiser like volume, pitch and timbre. The ADSR envelopes stands for attack, decay, sustain and release. The Attack of an Envelope Is the time its takes for the sound to reach it's full volume. For example if the attack is short, it will reach it's full volume quicker whereas if the attack is longer it will take longer for the note to reach it's full volume.The decay of an envelope is how fast the sound drops after the note has reach it's full volume. The sustain of an envelope, is the volume of the note it stays at after the decay. The release it how quickly the note fades after the note has been relased, if the release time is short, then the fade will be very quick, oppositely if the release time is longer than the note will take more time to fade.
