like photography :
accurate, but only from one point of view, at a given moment, in a given place.
|
like painting :
color flexibility but limited realism and needs to be done over to change point of view or environment.
|
like 3D :
can be very realistic and let you change any aspect but requires more programming and computation.
|
|
with sampling, you have the reproduction of a sound in a specific recording context (gear, room) and under specific performance conditions (player, pickup position for a guitar, etc).
|
Additive synthesis recreates a sound by adding sine waves at different frequencies just as you would add colors when painting.
|
First step is the analysis of a given natural sound generator and the physics involved and how they affect the final sound.
Second step is the recreation of this reaction with programming.

|
+ accurate soundwise on single shots
+ no much programming involved
+ light on cpu
- not accurate on reproducing expressive behaviours
- heavy on hard drive space and ram
- poor dynamics
- sounds can't be changed, appart from filtering and distortion.
|
+ can sound very convincing
+ light on hard drive & ram
+ seamless dynamics
- inherent lack of flexibility, requires "tricks" to fit with physical parameters.
- some expression traits related to pitch alteration (bends) and other oddities (guitar squeaks) can't be realistic
- can't accurately match a given real sound reference
- dynamics require tricks, making it complicated to reproduce real behaviours
|
+ can match a given real sound reference (sounds like a sample)
+ parameters corresponding to the reality
+ seamless and realistic dynamics
+ realistic expressivity
+ light on hard drive & ram
- can be heavy on cpu
- requires specific researches
