LAION-Audio-630K is a large-scale audio-text dataset consisting of 633,526 pairs with the total duration of 4,325.39 hours. It contains audios of human activities, natural sounds and audio effects, consisting of 8 data sources (see the data source table below) from publicly available websites. We collect these datasets by downloading audios and relevant text descriptions. Based on our current knowledge, LAION-Audio-630K is the largest audio-text dataset publicly available and a magnitude larger than previous audio-text datasets (by 2022-11-05).
Among the 8 datasets, we only release 4 of them (BBC sound effects, Epidemic Sound, Audiostock and Freesound). The first 3 datasets are available under csv format , since they are public available by anyone through URL links provided by correspondent websites. As to Freesound, we released the whole dataset (audio files + text caption) to Hugging Face. However, as to the others, i.e. Free To Use Sounds, Sonniss Game Effects, We Sound Effects and Paramount Motion Sound Effects, we would not release them because they are pruchased by LAION.
CSV files are of the following structure:
| url | caption1 | caption2 | ... | caption_t5 | {metadata1} | {metadata2} | ... |
|---|
- url: The URL of the audio file
- caption_i: the i-th caption of the audio file
- caption_t5: For Epidemic Sound, we adopted keywords-to-caption data augmentation using T5 model. Details could be found in the datacard of Epidemic Sound.
- {metadata_i}: Metadata could be the freesound id of the audio etc.
We provide a datacard for each dataset we processed, which record how we process it. If you want to learn more about caption generation as well as details of keywords-to-caption data augmentation, please read datacards available here (for Epidemic Sound dataset).
We provide two version of Freesound dataset.
- Freesound (full): The original Freesound dataset. Details could be found in its datacard.
- Freesound (no overlap): Made based on Freesound(full), with samples from ESC50, FSD50K, Urbansound8K and Clotho removed.
We have released the processed freesound dataset in Webdataset format to a Hugging Face repository

Recently, BBC sound effects have modified their website structure. In consequence, only 300 samples are available for download. So, unfortunately, we are no longer able to generate csv file using our old scripts. In the meantime, many scrappers exist on GitHub, such as https://github.com/alisomay/bbc-sound-effects-downloader. You may try them to see if they work.
We employ the keyword-to-caption model to augment labels of AudioSet and Epidemic Sound into corresponding captions with aid of a pre-trained language model T5. We also de-bias these captions by replacing, for example, "woman" and "man" with "person", aiming to eliminate potential gender discrimination. We hereby release the augmented captions for Epidemic Sound and AudioSet (in csv format).
