Here is a recording i made of a mobile phone vibrating in a metal tin. I needed this for a project i'm working on and thought i'd share it. Sennheiser mkh 416 - sound devices 442 - tascam dr680 - fabfilter mb (for slight noise reduction).
Three ringtones from my old beloved nokia 8210 (rest in peace). The first one is the classic nokia tune from the nineties. (discovered this recording in the vastness of old hard disks).
