| 描述: | To create this electrocardiogram, I generated a sine wave with a frequency of 1500 and an amplitude of 0.3 for a duration of 0.5 secondI repeated this sound 15 times at different intervals. I generated a sinusoidal wave again, but this time over a period of 5 seconds to reproduce the sound of a heart that stops on the electrocardiogram. To reduce the cutoff effect between sounds, I manually changed the levels to create fade in and out.In order to find a noise that is closer to an electrocardiogram I modified the balance of highs and lows, decreasing the bass and increasing the treble until finding a sound that comes closest. I also changed the pitch by decreasing it by trying to find the right sound, I lowered the volume to 2.6 dB and I arranged each sound accurately and added a silence between each sound.I then put a reverb effect to sublimate the whole thingFinally, I added a breath recording to make this sound more realistic, I decreased the volume to 12.2 dB over 8 seconds, because the sound of breathing was not equal on the rest of the recording and therefore decreased the rest to just 2.7 dB Typologie de Schaeffer :v’’ Morphologie : Masse : sons cannelésTimbre harmonique : acideGrain : Plutôt lisseAllure : pas de vibratoDynamique : attaque violente et abrupteProfil mélodique : pas de hauteursProfil de masse : / |
