How to test your sound effect

Written by


This task will focus on detection of sound events in combinations that are created. This use of information enables creating combinations of desktop daily sound and audio events of attention at background ratio that is different, providing a larger quantity of training requirements than will be available in recordings that are real. Audio dataset – TUT Rare Sound Occasions 2017 includes recordings of each day and isolated events for every target class acoustic scenes. For generating combinations source code could be supplied, together with a set of ready. For coaching their systems the participants are allowed to use any mixture of the data that was supplied. 

The evaluation set will consist of comparable mixtures. The target event classes are: Baby crying – Glass dividing – Gunshot – Target event classes that are sound would be treated therefore it is allowed to use approaches for detection, tailored to the features of each category. The desktop audio material is composed of recordings from 15 scenes that are audio, and is a part of TUT Acoustic Scenes 2016 dataset. Annotation and recording procedure – the sound illustrations were gathered from Freesound, and desktop audio is a part of TUT Acoustic Scenes 2016 dataset. Choice of sounds from Freesound was predicated on the exact label, selecting Illustrations that’d sampling frequency 44.1 kHz or higher. 

Annotations for the synthetic combinations are produced automatically by the mixture synthesizer. Annotations contain only the target audio event temporal position, since the task is independent of the desktop acoustic scene. Download – In case you’re utilizing the provided baseline system, there’s no need to download the dataset as the system will automatically download needed dataset for you. Development dataset – A minor bug was found in Exactly the Evolution dataset after initial release. Some desktop sound signals were found to contain also target audio events, affecting the evaluation result minimally. Ensure you update your dataset by utilizing the provided script. 

Comprehensive instructions how to use the script can be found here. Below is the most latest, updated version of the development dataset. The Evolution dataset contains the original desktop and isolated audio event samples, and a set of generated mixture audio samples. Participants can generate any quantity of additional combinations to be used in system training, utilizing the provided dataset. The development dataset contains about 9 hours of desktop audio, around 100 isolated sound examples for each target class, and 500 mixture audio examples for each target class, with each mixture containing 0 to 1 target sounds. The evaluation set would be produced the same way, using original audio material not distributed in development set, and would be supplied close to the challenge deadline. A detailed information of the dataset creation is accessible in: Development dataset – A pair of 500 combinations per target class is designated along with clearly marked as test material during system development.
