Abstract

3D audio spatializers for Virtual Reality (VR) can use the acoustic properties of the surfaces of a visualised game space to calculate a matching reverb. However, this approach could lead to reverbs that impair the tasks performed in such a space, such as listening to speech-based audio. Sound designers would then have to alter the room’s acoustic properties independently of its visualisation to improve speech intelligibility, causing audio-visual incongruency. As user expectation of simulated room acoustics regarding speech intelligibility in VR has not been studied, this study asked participants to rate the congruency of reverbs and their visualisations in 6-DoF VR while listening to speech-based audio. The participants compared unaltered, matching reverbs with sound-designed, mismatching reverbs. The latter features improved D50s and reduced RT60s at the cost of lower audio-visual congruency. Results suggest participants preferred improved reverbs only when the unaltered reverbs had comparatively low D50s or excessive ringing. Otherwise, too dry or too reverberant reverbs were disliked. The range of expected RT60s depended on the surface visualisation. Differences in timbre between the reverbs may not affect preferences as strongly as shorter RT60s. Therefore, sound designers can intervene and prioritise speech intelligibility over audio-visual congruency in acoustically challenging game spaces.

Data repository to supplement paper - Sankaran N, Lueng J, Carlile S (2014). Effects of virtual speaker density and room reverberation on spatiotemporal thresholds of audio-visual motion coherence.

Abstract: The present study examined the effects of spatial sound-source density and reverberation on the spatiotemporal window for audio-visual motion coherence. Three different acoustic stimuli were generated in Virtual Auditory Space: two acoustically “dry” stimuli via the measurement of anechoic head-related impulse responses recorded at either 1° or 5° spatial intervals (experiment 1), and a reverberant stimulus rendered from binaural room impulse responses recorded at 5° intervals in situ in order to capture reverberant acoustics in addition to head-related cues (experiment 2). A moving visual stimulus with invariant localization cues was generated by sequentially activating LED’s along the same radial path as the virtual auditory motion. Stimuli were presented at 25°/s, 50°/s and 100°/s with a random spatiotemporal offset between audition and vision. In a 2AFC task, subjects made a judgment of the leading modality (auditory or visual). No significant differences were observed in the spatiotemporal threshold (PSE) or the slope of psychometric functions (β) between all three acoustic conditions. Additionally, β was spatially invariant across velocity, suggesting a fixed spatial audio-visual integration window. Findings also suggest a key role for auditory de-reverberation in processing moving auditory stimuli and establish a perceptual measure for assessing the veracity of motion generated from finite and discreet locations.

DESCRIPTION:

The Sony-TAu Realistic Spatial Soundscapes 2023 (STARSS23) dataset contains multichannel recordings of sound scenes in various rooms and environments, together with temporal and spatial annotations of prominent events belonging to a set of target classes. The dataset is collected in two different countries, in Tampere, Finland by the Audio Researh Group (ARG) of Tampere University (TAU), and in Tokyo, Japan by SONY, using a similar setup and annotation procedure. The dataset is delivered in two 4-channel spatial recording formats, a microphone array one (MIC), and first-order Ambisonics one (FOA). These recordings serve as the development dataset for the DCASE 2023 Sound Event Localization and Detection Task of the DCASE 2023 Challenge.

The STARSS23 dataset is a continuation of the STARSS22 dataset. It extends the previous version with the following:

• An additional additional 2hrs 30mins of recordings in the development set, from 5 new rooms distributed in 47 new recording clips.
• An additional 1hr 40mins of recordings added in the evaluation set of the dataset.
• 360° videos spatially and temporally aligned to the audio recordings of the dataset (apart from 12 audio-only clips).
• Distance labels (in cm) for the spatially annotated sound events, instead of the previous azimuth and elevation only labels.

Contrary to the three previous datasets of synthetic spatial sound scenes of TAU Spatial Sound Events 2019 (development/evaluation), TAU-NIGENS Spatial Sound Events 2020, and TAU-NIGENS Spatial Sound Events 2021 associated with previous iterations of the DCASE Challenge, the STARS22-23 dataset contains recordings of real sound scenes and hence it avoids some of the pitfalls of synthetic generation of scenes. Some such key properties are:

• annotations are based on a combination of human annotators for sound event activity and optical tracking for spatial positions,
• the annotated target event classes are determined by the composition of the real scenes,
• the density, polyphony, occurences and co-occurences of events and sound classes is not random, and it follows actions and interactions of participants in the real scenes.

The first round of recordings was collected between September 2021 and January 2022. A second round of recordings was collected between November 2022 and February 2023.

Collection of data from the TAU side has received funding from Google.

A demo video combining the different modalities and spatial annotations can be found here.

AIM:

The STARSS22-23 dataset is suitable for training and evaluation of machine-listening models for sound event detection (SED), general sound source localization with diverse sounds or signal-of-interest localization, and joint sound-event-localization-and-detection (SELD). Additionally, the dataset can be used for evaluation of signal processing methods that do not necessarily rely on training, such as acoustic source localization methods and multiple-source acoustic tracking. The dataset allows evaluation of the performance and robustness of the aforementioned applications for diverse types of sounds, and under diverse acoustic conditions.

Specifically the STARSS23 allows evaluation of audiovisual processing methods with a spatial dimension, such as audiovisual source localization or audiovisual object recognition.
