Room Impulse Response (RIR) is an audio signal processing task that involves capturing and analyzing the acoustic characteristics of a room or an environment. The goal is to measure and model the way sound waves interact with the space, including reflections, reverberation, and echoes.

A new implementation of the Image Source Method is presented that dramatically improves the computation speed of the ISM by using Graphic Processing Units (GPUs) to parallelize both the simulation of multiple RIRs and the computation of the images inside each RIR.
A new impulse response (IR) dataset called MeshRIR is introduced, which consists of IRs measured at positions obtained by finely discretizing a spatial region and is suitable for evaluating sound field analysis and synthesis methods.
A neural-network-based fast diffuse room impulse response generator (FAST-RIR) for generating room impulse responses (RIRs) for a given acoustic environment that outperforms gpuRIR by 2.5% in an AMI far-field ASR benchmark.
Experiments show that FRA-RIR can not only be significantly faster than other existing ISM-based RIR simulation tools on standard computational platforms, but also improves the performance of speech denoising systems evaluated on real-world RIR when trained with simulated RIR.
Stochastic room impulse response generation method StoRIR, when used for audio data augmentation in a speech enhancement task, allows deep learning models to achieve better results on a wide range of metrics than when using the conventional image-source method.
This work shows that by playing the crafted adversarial perturbation as a separate source when the adversary is speaking, the practical speaker verification system will misjudge the adversary as a target speaker.
A shoebox room simulator able to systematically generate synthetic datasets of binaural room impulse responses (BRIRs) given an arbitrary set of head-related transfer functions (HRTFs) represented in Spatially Oriented Format for Acoustics (SOFA).
Experimental results indicate that the ability to generalize to different environments and unbalanced performance among different classes are two main challenges.
Adding a benchmark result helps the community track progress.
