Firstly, I decided to generate a click track. I kept only two clicks, and I changed the pitch of each one (deep for both, and one a bit deeper than the other). I also eased the high-pitched and highlighted the low-pitched.
I deleted a little silence moment which was between the clicks, in order to have a rhythm similar to heartbeat.
Finally, periodically, I repeatedly duplicated this clicks. CHAPEL_Dylan_2015_2016_Heartbeat.wav 聲道:1 類型:wav Heart-rate、Fake-sound、Heartbeat 心率、假聲、心跳 資料來源:freesound ( https://freesound.org )
