# Project map

> Part of [LISQM](https://zhenxianli.github.io/LISQM/) (List of Implementations of Sound Quality Metrics), a list of open-source implementations of psychoacoustic metrics. Data as of 2026-10-28. Web page: https://zhenxianli.github.io/LISQM/projects/map.html

Each line of the map joins two projects: code ported or adapted from another project, the author's own code moved between projects, a project that uses another one at run time, results checked against another project, or a shared contributor. The lines come from the implementation rows on the project pages. On the web page, arrows point from the source to the project that uses it, and a check points from the project to the one it checked its results against.

## Kinds of line

- **Ported or adapted from another project.** The project's code for a metric was ported from the source (translated into another language) or adapted from it (reused with changes), or the whole project continues the source. A grey box is a program published with a standard or a paper.
- **The author's own code.** The code was written by someone who also maintains the project that ported or adapted it: a contribution, a move or a translation within the same team, not a port by someone else.
- **Used at run time.** The project calls the source to compute the metric, or needs its results as input.
- **Results checked against.** The arrow points from the project to the one it checked its results against. Comparisons with the code a project was ported or adapted from, with a port of its own code or with another port of the same code are not drawn, because they only show that two versions of the same code agree.
- **Same contributor.** Someone has worked on both projects, as a maintainer or with code of their own. Not drawn beside a line of the author's own code, which says the same.
