I am member of this site for 5 years and (having contributed free samples also for freesound.or) I recently built my own website for free and lowcost sound samples, or sample packs. They are of experimental nature, lot of various stuff - from sounds of from a toolshed, bathroom, workshop or sounds of winter, fire to sampled wine glasses, mandoline, guitar etc. Sample packs are mapped for Native Instruments´s Kontakt 5, but they are unlocked you can use them also as wavs. if you search for somehing cheap and special for you musical productions, check out www.atomhub.com...
thank you and all the best to this great forum
