+# Freesound One-Shot Percussive Sounds Dataset
+
+
+This dataset contains 10254 one-shot (single event) percussive sounds from Freesound.org and the corresponding timbral analysis. These were used to train the generative model for "Neural Percussive Synthesis Parameterised by High-Level Timbral Features". 
+
+## Dataset Construction
+
+To collect this dataset, the following steps were performed:
+
+* Freesound was queried with words associated with percussive instruments, such as "percussion", "kick", "wood" or "clave". Only sounds with less than one second of [effective duration](https://essentia.upf.edu/reference/std_EffectiveDuration.html) were selected.
+
+* This stage retrieved some audio clips that contained multiple sound events or that were of low quality.
+Therefore, we listened to all the retrieved sounds and manually discarded the sounds presenting one of these characteristics. For this, the [percussive-annotator](https://github.com/xavierfav/percussive-annotator) was used.
+
+* The sounds were then cut or padded to have 1-second length, normalized and downsampled to 16kHz.
+
+* Finally, the sounds were analyzed with the [AudioCommons Extractor](https://github.com/AudioCommons/ac-audio-extractor), to obtain the AudioCommons timbral descriptors. This information is contained in the 'analysis' folder.
+
+
+## Dataset Organisation
+
+The dataset contains two folders and two files in the root directory:
+
+* 'one_shot_percussive_sounds' encloses the pre-processed audio files. These are named '<freesound_sound_id>.wav'
+
+* 'analysis' holds the AudioCommons analysis files for each of the sounds in the dataset. This analysis is stored as a .json file, named '<freesound_sound_id>_analysis.json', with a key for each of the features extracted.
+
+* Two more files are present in the root directory of the dataset: this 'README' and the 'licenses.json'. The latter one is a '.json' file containing the name, the username of the uploader and the license for each of the sounds in the dataset.
