This README would normally document whatever steps are necessary to get your application up and running.
### What is this repository for? ###
* Quick summary
Synthesis tranform is an AIM used for transferring the time-frequency domain multichannel signals into the time domain. This file introduces the setup for standalone application.
* Version
01.01.220708
* [Technical specifications MPAI-CAE v1.3](https://mpai.community/standards/resources/)
### How do I get set up? ###
* Summary of set up
The development language is C++. C++11 or its newer versions support compiling the code. See the list of C++ compilers. (https://en.wikipedia.org/wiki/List_of_compilers#C++_compilers)
This software uses a third-party fftw-3.3.9 that can be also downloaded from the link. (https://fftw.org/)
