I play three notes on tenor trombone: Bb3, Bb2 and Bb1. They are all in first position. The first two notes are in the standard range of the trombone, while the last note is a pedal tone. This occurs when the instrument resonates at the fundamental, rather than the 2nd harmonic. Pedal Bb is relatively easy on trombone, but much harder on trumpet (I'm unable to do it, despite being proficient at trumpet and at a beginner's level on the trombone).
This is an antique georgian cuckoo clock recorded in the sacred halls of abberknackee, under the auspicious gaze of the lord and saviour herbert the mincing.
Just a normal clock ticking. I created this sound for a radio report about the change from winter to summer time. For recording i used a simple zoom recorder.
Old electromechanical clock ticking "yantar'". Electromechanical watches "amber", orlovsky watch factory, were made in 1977, the housing is made of wood, quartz movement. --recorded mono with sennheiser mkh40.
Sound of my binger wristwatch ticking. I used phase cancellation to get rid of the noise floor except for the ticks. At lower volumes it sounds very convincing. I draped the watch over my microphone - the blue yeti pro.
