Below are some attempts to imitate a real world sounds using csound interface.

Snow Crunching

snow crunch.wav

On frosty morning sometimes you walk a path covered with rammed snow and you might here a glorious winter crunchy sound. =)

This effect above I achieved through Gaussian noise envelop with instruments components set to the following values:

start

duration

amplitude

freq

carRatio

modRatio

envshape

modshape

max modulator amplitude

min modulator amplitude

You can get a taste of the real world sound from a video:

The speaker is sort of creepy, but thank you for bearing with it, because the sound of snow is great there.

It was really interesting to listen to an imitation of snow crunching without seeing the snow itself, because without visual input, a couple of other things that make a similar sound came to my mind: wood burning and a rat scratching its way though. Also I was surprised to find that if you change just one little component like the maximum value in the envelop, it becomes noise. Quite fascinating it is that some world sounds are very close to something quite chaotic and not too pleasant to hear.

?'Lion' Purring

Quotes due to that lions are not actually known to purr.

It is a very low frequency sound, so make sure you have suiting speakers/headphones  in order to listen to it.

Envelop function had amplitude varying for the purr effect:

This purring tune is very close to a motor roaring by the sound of it, which is funny, since cat purring is usually perceived as much more pleasant compare to motor's sounds.

An interesting common believe that a low frequency sound has a healing affect, which is why cats purr around ill people and when they are hurt themselves. Multiple studies shown that vibrations produced by such low frequencies help bone growth and healing fractures.

While playing with pitch of crunching snow sound I realized that it sounds a lot like rain too. So overlaying different frequencies of crunching snow symbolize in my piece a kind of pain which is growing until purring comes and heals that pain to seize.
