My quest today has been to try and replicate it using household items. <\/p>\n<p><a href=\"http:\/\/tungstenfilamentgroup.com\/blog\/wp-content\/uploads\/2015\/03\/P1030474.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/tungstenfilamentgroup.com\/blog\/wp-content\/uploads\/2015\/03\/P1030474-300x225.jpg\" alt=\"P1030474\" width=\"300\" height=\"225\" class=\"alignnone size-medium wp-image-912\" srcset=\"http:\/\/brynschurman.com\/blog\/wp-content\/uploads\/2015\/03\/P1030474-300x225.jpg 300w, http:\/\/brynschurman.com\/blog\/wp-content\/uploads\/2015\/03\/P1030474-1024x768.jpg 1024w, http:\/\/brynschurman.com\/blog\/wp-content\/uploads\/2015\/03\/P1030474-624x468.jpg 624w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<p>I recorded various pen caps, spray can lids, measuring scoops, and finally, the plastic tube from a candy whistle. Here is a shootout of the various items:<br \/>\n<audio class=\"wp-audio-shortcode\" id=\"audio-910-1\" preload=\"none\" style=\"width: 100%;\" controls=\"controls\"><source type=\"audio\/mpeg\" src=\"http:\/\/tungstenfilamentgroup.com\/blog\/wp-content\/uploads\/2015\/03\/testing_shelldrops.mp3?_=1\" \/><a href=\"http:\/\/tungstenfilamentgroup.com\/blog\/wp-content\/uploads\/2015\/03\/testing_shelldrops.mp3\">http:\/\/tungstenfilamentgroup.com\/blog\/wp-content\/uploads\/2015\/03\/testing_shelldrops.mp3<\/a><\/audio><\/p>\n<p>The candy tube seemed like the closest bet as I was recording, but it was missing the metallic impact from when a shell casing is dropped on the brass end, near the primer. I decided to tape a nickle to the end of the tube to see if that would get me in the neighborhood. <\/p>\n<p><a href=\"http:\/\/tungstenfilamentgroup.com\/blog\/wp-content\/uploads\/2015\/03\/P1030475.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/tungstenfilamentgroup.com\/blog\/wp-content\/uploads\/2015\/03\/P1030475-300x225.jpg\" alt=\"P1030475\" width=\"300\" height=\"225\" class=\"alignnone size-medium wp-image-913\" srcset=\"http:\/\/brynschurman.com\/blog\/wp-content\/uploads\/2015\/03\/P1030475-300x225.jpg 300w, http:\/\/brynschurman.com\/blog\/wp-content\/uploads\/2015\/03\/P1030475-1024x768.jpg 1024w, http:\/\/brynschurman.com\/blog\/wp-content\/uploads\/2015\/03\/P1030475-624x468.jpg 624w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<p>After listening to recordings, however, the back end of the weighted candy tube didn&#8217;t bounce like a proper shell. The solution was to splice the elements together. With a few steps worth of pitch shifting, the sharpie lid seemed to have the right tone and number of bounces compared to the source recordings. <\/p>\n<p>On the implementation side, I decided to use separate playlists for the initial impacts and the bounces. This way, I didn&#8217;t have to splice together the nickle-weighted candy tube and sharpie recordings, not to mention the bigger possibilities for randomization within the sound engine. I combined the best impacts from each category into its own .wav file, duplicated them and set the start and end points within Wwise thusly. <\/p>\n<p><a href=\"http:\/\/tungstenfilamentgroup.com\/blog\/wp-content\/uploads\/2015\/03\/shotgun_tails.png\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/tungstenfilamentgroup.com\/blog\/wp-content\/uploads\/2015\/03\/shotgun_tails-300x175.png\" alt=\"shotgun_tails\" width=\"300\" height=\"175\" class=\"alignnone size-medium wp-image-922\" srcset=\"http:\/\/brynschurman.com\/blog\/wp-content\/uploads\/2015\/03\/shotgun_tails-300x175.png 300w, http:\/\/brynschurman.com\/blog\/wp-content\/uploads\/2015\/03\/shotgun_tails-1024x599.png 1024w, http:\/\/brynschurman.com\/blog\/wp-content\/uploads\/2015\/03\/shotgun_tails-624x365.png 624w, http:\/\/brynschurman.com\/blog\/wp-content\/uploads\/2015\/03\/shotgun_tails.png 1661w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<p>Here is a video of the revised shotgun shell implementation in action.<\/p>\n<p><iframe loading=\"lazy\" width=\"640\" height=\"480\" src=\"https:\/\/www.youtube.com\/embed\/NZZXvogtirI?rel=0\" frameborder=\"0\" allowfullscreen><\/iframe><\/p>\n","protected":false},"excerpt":{"rendered":"<p>My folks got me a Cold Gold hydrophone for my birthday last weekend and I&#8217;ve been having fun playing with it over the past few days.
