Some known tools that you can use to implement pitch shifting are: pitch correctors like Melodyne or Auto-Tune, synths capable of granular synthesis like Absynth, some DAWs have their own native implementation like Live's algorithms: beats, tones, texture, complex, and complex pro.

Relationship between harmonics is conserved, and no harmonics are added or removed.Д¬hange of pitch without changing the time. This implementation has one particularity: your sample will become shorter or longer as you tweak its pitch, as pitch is being modified through the playback speed. You can use a sampler to decrease the playback speed by either tweaking it explicitly (most samplers will have this function named as 'transpose') or by playing the sample through a note lower than the one assigned to it. Here is an overview of four tools that will help you carve any voice sound you can think of, and more. What if you want to make something sound 'artificial'? What if you want to go beyond 'artificial' and 'natural'.Д«y knowing the tools you have available you can achieve any result you are looking for, without limiting yourself to a specific scope. But by doing that you would limit your knowledge to that very small scope. To answer your question more specifically you would need to define 'artificial' and 'natural' first. It's clear that you have a different one. Now you have changed the pitch of the voice, while leaving the natural resonances of the voice where they belong.Д«ut that's my definition of 'natural'. When you use pitch shifting you will move those resonances too, something that doesn't happen in 'real life'.ДЄfter pitch shifting, you can compensate by moving those resonances where they belong to using formant manipulation (or maybe frequency shifting).

The human voice has some complex dynamics, and one of them is that there are specific resonances that remain constant no matter what note you sing. One common approach to achieving very natural results is combining formant manipulation and pitch shifting. Which of these 4 techniques will sound more natural? It depends on you and how you implement them. Your example sounds like something formant manipulation would do, but there is no way to know for sure without having the original voice sound as reference. Each has its own sound, each will provide different results. I can think of 4 ways to achieve that low-pitched voice: playback speed (aka a sampler's transpose), pitch shifting, frequency shifting, and formant manipulation. I guess 'natural' is a pretty broad and somewhat subjective concept, so for simplicity we will define 'more natural' as 'inducing less change' and 'less natural' as 'inducing more change'. To me it seems that the sound was intentionally designed to sound unnatural. It's interesting that to me your example doesn't sound natural at all.
