It also has a hearing aid simulator, and a binaural spatiali= ser. Here is a video demonstrating the hearing loss functions https://www.youtube.com/watch?v=3DjtEL__hwmq0 The Test Application (the one you see in the videos) is available for MacOS= , Windows and Linux at the following link: https://github.com/3DTune-In/3dti_AudioToolkit/releases/latest At the link above, you can also download the VST plugin, both for MacOS and= Windows, as well as the Unity wrapper Best Lorenzo -- Lorenzo Picinali Professor in Spatial Acoustics and Immersive Audio Dyson School of Design Engineering Imperial College London Dyson Building Imperial College Road South Kensington, SW7 2DB, London E: l.picinali@xxxxxxxx https://profiles.imperial.ac.uk/l.picinali https://www.axdesign.co.uk/ https://www.sonicom.eu/ ________________________________ From: AUDITORY - Research in Auditory Perception <AUDITORY@xxxxxxxx>= on behalf of Pragati Rao <pragatir@xxxxxxxx> Sent: Friday, March 7, 2025 10:26 PM To: AUDITORY@xxxxxxxx <AUDITORY@xxxxxxxx> Subject: [AUDITORY] Hearing Loss simulator for processing audio files Dear Colleagues, I am looking for a hearing loss simulator that can simulate the impact of I= HC and OHC loss when a given audiogram is fed and then process audio files = with that information. This is so that a more nuanced impact of various deg= rees of hearing loss/shapes of audiogram on specific audio files can be sho= wn instead of using band-pass filtering.
