Overview

The current structure of bgm.json is straightforward, containing only 6 keys: title, size, duration, bitrate, sample_rate, and link. The information for size, duration, bitrate, and sample_rate is extracted using the python TinyTag package. Additionally, bgm_link.json is provided for those who are only interested in the audio file.

Tip

The file itself is extracted using the ffmpeg library with the libvorbis -q:a 5 (ogg) format to achieve a smaller file size compared to other formats, while preserving the sound quality as much as possible from the source.

Data Structure

type Link = string;

type BackgroundMusic = {
  title: string;
  size: number;
  duration: number; // float64
  bitrate: number; // float64
  sample_rate: number; // float64
  link: Link;
}

// bgm.json
type BackgroundMusicData = {
  [key: string]: BackgroundMusic;
};

// bgm_link.json
type BackgroundMusicLinkData = {
  [key: string]: Link;
};
