CHAD: Cover and Hummings Aligned Dataset

This repository contains the official code of the paper "A Semi-Supervised Deep Learning Approach to Dataset Collection for Query-by-Humming Task" published in the Proceedings of the 24th International Society for Music Information Retrieval (ISMIR) Conference, Milan, 2023.

The code is used for downloading the cover part of the dataset.

UPD:

The hummings subset of the dataset is now available on HuggingFace!

ToDo's

• Set up the repository
• Add the dataset download pipeline
• Include metadata in the download pipeline
• Write the README.md
• Upload the humming part of the dataset to HuggingFace

---

Dependencies

To install all dependencies, run this command:

pip install -r requirements.txt

---

Usage

To download the dataset, you can use the following command:

bash run.sh

This command runs the main.py script, which provides the following command-line options:

Usage: main.py [OPTIONS]

Options:
  --csv-path TEXT          Path to the CSV file containing dataset information
                           [required]
  --tgt-dir TEXT           Target directory for saving audio files and
                           fragments  [required]
  --extension TEXT         Extension of saved audio files
  --download-hf-dataset    Download hummings subset from HuggingFace
  --save-fragments-audios  Save audio fragments
  --save-full-audios       Save full audio files
  --save-metadata          Save YouTube metadata information
  --n-processes INTEGER    Number of processes for parallel processing
  --sr INTEGER             Sample rate for audio
  --mono / --no-mono       Mono or stereo audio
  --help                   Show this message and exit.

By running this command, you initiate the download of audio files firstly, from HuggingFace repo, and secondly, from YouTube and extraction of the necessary fragments from them.

In addition, there is a Jupyter Notebook notebooks/show_examples.ipynb, which displays random excerpts from the dataset.

Dataset Structure

The metadata/dataset.csv file provides information with the following fields:

• group_id: An identification code that serves as an identifier for a group of fragments. Essentially, it represents a unique track.
• fragment_id: An identification code assigned to each fragment within a group. A single group can contain multiple fragment IDs.
• id: An identification code that represents a specific version of a fragment, which can be a humming, cover, or the original track fragment.
• audio_type: This field indicates the type of the fragment, which could be categorized as 'original,' 'cover,' or 'humming'.
• youtube_id: A unique YouTube ID that links to the corresponding video.
• interval: The interval represents the left and right timestamp boundaries of the fragment within the full audio.
• correlation: Correlation value from 0 to 1 indicates the degree of similarity between a cover fragment and its original version.
• check_by_crowdsource: A boolean flag indicating whether the fragment underwent additional crowdsource assessment to determine its similarity to the original.
• is_available: This field specifies whether the YouTube video related to the fragment is currently available or not.
• duration: Duration denotes the length of the fragment in seconds.

The downloaded dataset is structured as follows:

├── {GROUP_ID}             
│   ├── {FRAGMENT_ID}        
│       ├── {ID}.{EXTENSION}
│       └── ...
│   └── ...
└── ...

This structured hierarchy organizes the audio files and fragments, making it easier to navigate and work with the dataset.

Hummings Subset

You can download the dataset directly via HF or using main.py with the flag --download-hf-dataset.

The tar.gz filestructure is the same as in the whole dataset.
