1. I bought an (ab)used and damaged midi synth. It gives me some very weird noises to record and edit. Its very unpredictable.
2. It had only been few minutes since a massive rain, ambiance was still wet, I carried a hand held sound recorder(Roland) and sat on a wet highway sidewalk, late at night, and I got some beautiful effects of cars whooshing by.
3. Hit the basketball on the solid tiled ground - record it - do the required filter tweaking and get a unique analog kick(Can try other balls and other flooring for better aural response).
4. I once stood on a rail bridge and recorded the passing train(I was dangerously close to the train, hence I'll not recommend this). Anyhow, I ended up not using it anywhere. It wasnt that good.
5. Place a table fan(run it on slow speed)between source of sound(Voice is recommended) and mic(Large diaphragm mic), get a very interesting stutter.
6. Try speaking anything and record it(Can, actually, take any voice. But it must be spoken one, not a sung one.) - take another track of synth melody - place sidechain compressor over synth melody - define vocal recording as the source for the sidechaining - put some subtle(Very subtle) automation on synth filter cutoff - keep resonance low(Not very low) - set the gain accordingly - and finally let the voice modulate synth sound - synth will start trying to say something. Loud and clear vocals will help.
7. Deep Fry something on the pan - and record the noise - get a nice warm sound effect of rain - pass the recording through some effects like reverb(But very subtle. I repeat, very subtle).
Note:- Let the reverb always be a mushy Utopian gadget for 'Enya' like aliens. Less of it is better, but remember less doesnt mean inaudible.
8. Light a match - record it upclose - trim the middle portion of the sample - shape it into a sustain loop - put no effect at all - no compressor even - although, can use filter to take care of few anomalies like background hiss or any click or glitch - turn the level absolutely down - try mixing this sustain loop into any track or song by bringing up the level - raise the level very carefully so that loop is barely audible - and soon fade back in - and continue fiddling level whenever feel required.
9. I once recorded my fart. Never used it though.
10. And snores.
