In the previous post, I introduced my current project, which is comparing multiple additive synthesis implementations, and to find out which one of them is the fastest. I hope to use the results of this project to design a new software synthesizer with unique features. In this post, I will talk more about how I evaluate each of the additive synthesis implementations for speed and accuracy. I will also present other evaluation details.

Additive synthesis is a technique that gives synthesizers precise control over each individual partial of a sound. Currently, I am working on an software synthesizer that will use additive synthesis to implement certain acoustic features. However, performing additive synthesis by simply adding multiple sine waves together can become computationally expensive, especially when multiple musical notes are being played together simultaneously. This blog post is the first of a series of blog posts that will investigate different implementations of additive synthesis, and help me determine a computationally efficient implementation of additive synthesis for the software synthesizer that I am currently making. The github respository for this entire project can be found here.
The (doubly) linked-list container allows for constant-time insertion and removal. However, the list implementation in the C++ standard library must dynamically allocate each new list node upon insertion; and dynamic memory allocation incurs additional runtime costs. A linked-list implementation where users can preallocate and supply the list nodes themselves can speed up insertion and removal time by avoiding the cost of dynamic memory allocations. To that purpose, I have implemented an alternate version of linked-list called NodeList (see github repository).
