Good Sound Software

[reminder]

a quick questions.

I am looking for a software that has a library of sounds (pre-created sounds) that I can use in my project. For instance, sounds like: ocean waves, gun fires, sword fights, cars, crying, laughing....etc

Also, are there any software to easily modify voices, e.g. modify male voice into a child'c voice.

Any help on this plz. thanks

come on guys, I am sure you can recommend me something.

I may be bad in putting down my thoughts, but I am sure you can understand what I am asking for.
