What is the source of the audio files you sped up to get the effects?

My other audio packs honestly, some sounds of reloads i got into a local gun store, some sounds of impact i did hitting my guitar, stuff like that, they're basically sounds from my other packs speed up, that's why i feel like it's unfair to charge anything, i just took the sounds i already recorded and pitch it up.
