This sound of space was made entirely with Audacity and the idea was to start out with the sound of the alarm that I made before.

So, first I generated a sinusoïde tone to 440 Hz with an amplitud of 0.2 during 3 seconds.
I selected the track and I added a distorsion effect with a soft saturation and a saturation tripping threshold at -30,00, a hardness to 8,00 and an input gain at 8,00.
Then I decided to apply the egalisation effect and the normalisation one to -2,0 dB.
After that, I copied and pasted underneath, my "alarm" sound.
I changed the gain to the alarm sound to -23 dB.
I selected my two tracks and I added the effect : reverse.
At the end I put the Paulstretch effect with a stretching factor to 10,0 and a resolution to 0,25 seconds.
