This is a new release of the fastACI toolbox: the MATLAB toolbox for investigating auditory perception using reverse correlation. The current release includes scripts for the replication and reproduction of extra publications or other disseminated results (e.g., publ_carranante2023_FA_figs.m, publ_osses2023a_JASA_EL_figs.m, publ_osses2023b_FA_figs.m). In this release, there are are a number of new experiments to which revcorr has been applied, including: segmentation, toneinnoise_ahumada1975, and an extension to speechACI_Logatome to support more VCV contrasts.
