Earth song sound - NASA recording -real. Soundscape Composition at SFU. Practical Synthetic Sound Design. Nine Components of Sound. Loudness The loudness of a sound depends on the intensity of the sound stimulus. A dynamite explosion is loader than that of a cap pistol because of the greater amount of air molecules the dynamite is capable of displacing. Loudness becomes meaningful only if we are able to compare it with something. The sound of a gunshot may be deafening in a small room, but actually go unnoticed if fired in a subway station when a train is roaring past. (A film that use this in the narrative is Sleepers - when a man is shot at the same time as an aircraft is landing) "Equal loudness" Humans are most sensitive to frequencies in the midrange (250 Hz - 5000 Hz) When two sounds, a bass sound and a middle range sound are played at the same decibel, the listener perceive the middle range sound to be louder. This is why a clap of thunder in a horror movie may contain something so unweatherlike as a woman's scream.
Rhythm Rhythm is a recurring sound that alternates between strong and weak elements. Attack Sustain.
Sound Modelling. SouthPole Expedition Part 3: Pattern Sequenced ADSR Envelopes | AudioMulch.com. ADSR (Attack Decay Sustain Release) envelopes provide a way to specify how sound synthesis parameters such as filter cutoff and gain change over time. They support the synthesis of evolving timbres and are commonly found in analog synthesizers where the envelopes are triggered by pressing keys on the keyboard. With three ADSR envelope generators, AudioMulch's SouthPole contraption provides plenty of scope for envelope controlled filter modulation. In this post I'll demonstrate triggering the envelopes from their built-in pattern sequencers to create rhythmic patterns of filtering and gating. I'll use this functionality to synthesize some basic drum sounds and later to filter and gate samples. Before reading on you might want to review my previous posts exploring AudioMulch's SouthPole contraption: In part 1 I introduced the basic structure of SouthPole.
