Freesound Timeline is an app that automatically generates soundscapes using the most popular sounds from Freesound for a given year and month. I originally implemented Freesound Timeline back in 2011 when I was starting to learn about web technologies. In 2018 I updated it to make use Freesound APIv2 and the Web Audio API, and to add new killer features such as random spacialization of sounds in a 3D space (using WebAudio’s HRTF panning), and the autoadvance mode to let Freesound Timeline automatically advance through Freesound history. A new shiny interface was added in 2019, designed by the great Tony Martinez.
I hoped usage instructions would not be needed, but just in case:
Choose a year an and a month and hit the play button. Freesound Timeline will start playing a soundscape based on popular sounds added to Freesound during that year and month.
Set the density to a value between 5 and 100. The higher the value, the more dense will be the generated soundscape (i.e. more sounds playing at the same time).
Switch between RT and DL modes to change the way in which Freesound Timeline chooses the most popular sounds for a given month an year. DL mode will select sounds based on number of downloads. RT will do it based on average rating.
Turn autoadvance mode on or off to let Freesound Timeline slowly move ahead in time starting on the year and month you previously selected.
Here are a couple of examples of soundscapes that I generated with Freesound Timeline:
