LAMA World Music Genre Dataset

LAMA World Music Genre Dataset LAMA - LatinAmerica, Asia, MiddleEastern, Africa Genre Dataset This Dataset consists of the .wav files of audio classified into four categories: LatinAmerica, Asia, MiddleEastern, and Africa. We went through Google AudioSet ontology and pickled the ones we double-chekched to be from the region. We added 1-min audio (.wav), plots (.png), and numerical datapoints for training (.json). I hope that this work can help in several Deep Learning, Machine Learning projects in Music Genre Classification. Getting Started The data contained in LAMA can be classified into three categories: ->>>Section Format LatinAmerica Asia MiddleEast Africa audio .wav 535 539 548 645 graph plots .png 2140 2156 2192 2580 numerical .json 101650 102410 104120 122550 Overall statistics of LAMA. The numbers in “audio” and “plots” rows are counts of the included files in each section. The numbers provided in the “numerical” row are counted based on the total number of raw datapoints. Datapoints from two related files (trainMFCC.json, trainSC.json) were counted. Datapoints from trainZCR.json, and trainRMSE.json were not counted in this figure. LatinA refers to Latin America, and MiddleE refers to Middle East. What's in? audio .wav -> 1 min clip audio files from Latin America, Africa, Asia, and Middle East graph plots .png -> MFCC, STFT, FFT, waveform numerical .json -> x13 MFCC datapoints, x6 spectral contrast datapoints

LAMA世界音乐流派数据集
LAMA——拉丁美洲、亚洲、中东与非洲音乐流派数据集

本数据集包含已分类为四大类别的.wav格式音频文件，分别对应拉丁美洲、亚洲、中东与非洲区域。我们参照Google AudioSet本体库，筛选出经双重校验确认为对应区域的音频样本。此外还补充了1分钟时长的.wav音频文件、.png格式可视化图谱以及用于模型训练的.json格式数值数据集。希望本数据集能够为音乐流派分类相关的深度学习、机器学习项目提供助力。

## 快速入门
LAMA数据集的数据可分为三大类别，数据集格式说明如下：

| 数据类型 | 拉丁美洲 | 亚洲 | 中东 | 非洲 |
|--------------------|----------|--------|--------|--------|
| 音频（.wav） | 535 | 539 | 548 | 645 |
| 可视化图谱（.png） | 2140 | 2156 | 2192 | 2580 |
| 数值数据集（.json） | 101650 | 102410 | 104120 | 122550 |

### 数据集总体统计说明
LAMA数据集的统计信息说明如下：
1. "音频"与"可视化图谱"行的数值为对应类别下的文件总数量；
2. "数值数据集"行的数值为原始数据点的总数量，该统计包含了trainMFCC.json与trainSC.json两份相关文件的数据点，但未计入trainZCR.json与trainRMSE.json的数据点。

注：文中LatinA指代拉丁美洲，MiddleE指代中东。
