Subject: Re: [AUDITORY] Tolerance time interval for piano performance recognition From: OKAZAKI Satoshi <sat.okazaki@xxxxxxxx> Date: Sun, 31 Mar 2019 15:58:20 +0900 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>Hi Federico, I wrote my PhD thesis about "tolerance time interval=E2=80=9D (a.k.a. = simultaneity window, or I call "perceptual simultaneity range=E2=80=9D) = in 2018. I measured the time interval not for piano sounds but for two pure = tones. However, below may be helpful to you. S. Okazaki and M.
