For the fifth Decibels Challenge, the dataset provided was by Loud Numbers :https://github.com/loudnumbers/environmental_data

For this challenge, I wanted the sounds to represent the increase in CFCS gases as well as the accumulation of CO2 that is being seen annually. I decided to add an insect sample to the mix of sounds as a representation of the natural realm that is being affected by these changes.

Data

Column usage in Code

• year

  • Used as the counter between iterations

• co2annual

  • Divided by 3.3, so the max note is 127

  • Represented by the Chiplead synth

      use_synth :chiplead
      play Environmental[i]["co2annual"].to_f/ 3
    

• tempannual

  • using the data within this column to affect the rate of the following sounds (Guitar & Insects)

  • Acts as the background sound, heard throughout

•   sample :guit_e_fifths, rate: Environmental[i]["tempannual"].to_f  # rate affected by tempannual
          sample "C:/SonicPi/SoundStreams/Samples/Samplings/Samplings/James/insect-19.wav", rate: Environmental[i]["tempannual"].to_f  # rate affected by tempannual
  

• sunspots

  • Kept the range between 0 to 127 through the division of 2

  • Represented by the Piano Synth

      use_synth :piano
      play Environmental[i]["sunspots"].to_f/2 #range till 127
    

• oilspills

  • Represented by a distorted Piano Synth

•     with_fx :distortion do
  
        use_synth :piano
        play Environmental[i]["oilspills"].to_f/ 3, sustain: 2
  
      end
  

• cfcs

  • With the numbers increasing but still falling in a range of 0.965 to 3.287, It was the perfect column to have as the sleep between each iteration.

      sleep Environmental[i]["cfcs"].to_f
