Recording of my own fireplace made with a Tascam DR-40 (internal mics). I blasted up the lower freqs, kept the mid-range close to 0, then from 5-16 khz went back way up, slowly tapering down to below zero for the highest frequencies. All editing done in Audacity, compressed using Soundkonverter in Linux. This is a good sound effect for either a bonfire or a house burning down, which is what I made it for.
