PlaylistFilterForSpotify

Program to filter tracks of a Spotify playlist + plotting them in 3D.
Useful for

• Selecting tracks with similar style from a playlist that contains a wider range of music.
  Using Spotify's
  • Audio features
  • Recommendations (based on Artists and Tracks)
  • Genres

(These are my personal use-cases, and whats currently supported. For further features see: WIP)

Filtering Overview

Visualization Overview

Controls (3D Plot camera)

• Hold RMB to enter fly mode and use the mouse to look around + WASD and EQ(up/down) to move
• Hold MMB (or Ctrl + RMB) and move the mouse to rotate around the center.
• Hold shift + MMB (or Ctrl + RMB) to pan the camera
• Scrollwheel to zoom in/out

Building

Currently builds using Clang and CMake on Windows. (Line 34 in cryptopp's config-os.h needs to be commented out when using clang on windows, but it seems to work)
Requires vcpkg for gathering the required packages. Its root directory must be stored in the VCPKG_ROOT environment variable.
Building from source also requires you to provide your own Api Access through a secrets.hpp file in src/PlaylistFilter/Spotify/. This file should define the following variables:

static const std::string clientID = "...";

static const std::string base64 = "...";
// base64 contains base64_encode(clientID+":"+clientSecret)

static const std::string redirectURL = "...";
// eg: "https://olesenjonas.github.io/" 
// Needs to match the one defined in Spotify's app dashboard

static const std::string encodedRedirectURL = "...";
// eg: "https%3A%2F%2Folesenjonas.github.io%2F"

Client Secret and ID can be retrieved after registering an application at https://developer.spotify.com/dashboard/applications

Cross-Platform

Windows only code is used for two cases:

• string <-> wstring conversion using MultiByteToWideChar
• Opening URL using ShellExecute

Creates #errors instead in those places if _WIN32 is not defined.

Platform also needs to support Opengl 4.5 (could definitly be downgraded to a lower version with some code changes)

WIP

These are things I think are useful but are not implemented yet (and may never be):
(In no particular order)

• Error Handling (Spoiler: theres currently almost none, but really should be)
  Especially for:
  • access-token timeout (shouldnt happen atm since its automatically refreshed, but better to be safe than sorry)
  • Api requests limit (blocking other requests once limit is reached, and re-sending failed ones)
• Fuzzy-String comparisons for searching
• Manually control "Split" between Pinned- and Filtered- tracks tables in the main windpow
• More Font ranges (currently only chinese, korean and japanese are loaded in addition to latin characters)
• Safer loading of album covers (currently downloads and uploads to GPU are just fire-and-forget through detached threads, without checking if they even finish)
• Option to combine genres in different ways (currently track just needs to match any of the selected genres) but matching all genres could also be beneficial
• Better (looking) UI
