Removed the hum from cognito-perceptu's pill-bottle-4 sample. Original sample had truck in background in addition to some low frequency hum. Used the remove hum feature on izotope rx2 and, presto-chango, no distracting background noise. Now there is still a high frequency hum which i did not touch. I think this could be mitigated with a low pass filter in eq if you choose.
For this song i opened a coca cola bottle and i used 2 effects:- i change the tempo in order to speed the song- j'ai amplifié les basses pour avoir un peu de contenance.
For this third sound i used a plastic bottle that i typed in rhythm a table. I applied a dissolve, a development of the basses and changed the height. Then i truncated the silences and made a dissolve in closure.
