HM4 VS spectrum

- No allocations, no std::string - Optimization of nearby cells - GeoHash::nearbyCells() - Different units and "geo-spheres". Theoretically can work on the Moon and any other planet. - Demo usage in main.cc - Suppose to be part of HM4 (https://github.com/nmmmnu/HM4)

In some real situations, you may want to overwrite next variables. For example if this was a C struct - I have code similar to this here - https://github.com/nmmmnu/HM4

Introducing my terminal-based music player: spectrum I'm thrilled to share with you the project I've been working on: a feature-packed terminal-based music player written in C++. This player goes beyond your typical music playback and brings some cool features to the command line experience. Here are some of the standout features of spectrum: 1. Audio Equalization: it empowers you to fine-tune your audio experience. With a built-in equalizer, you can adjust the bass, treble, and other frequencies to create your perfect sound signature. 2. Lyrics Search: it provides a lyrics search functionality, allowing you to find and display lyrics for the currently playing song. 3. Sleek User Interface: While it runs in the terminal, it doesn't compromise on visual appeal. The player sports a sleek and intuitive user interface with easy-to-use commands and a real-time audio visualization that adds a touch of style to your listening experience. If you're interested in checking out this project, head over to GitHub repository to find the source code and installation instructions. I'm constantly working on improving the player, so any feedback, bug reports, or feature requests are greatly appreciated! Give spectrum a try, and let me know what you think. Happy listening!
