250 Royalty-Free Audio Tracks for "Pulse Width"

Skype interference or feedback sound effect. Its the sound your computer makes if your speakers are too loud. What happens is that your computer plays the sound coming from the person on the other side and then it plays over there and then plays back on your computer, it builds up in waves. Just turn your sound down and it should go away.

A hypnotic pulse sound.

Quiet water dripping from a kitchen sink tap, with a rate going from approximately 99bpm down to 94bpm by the end of the recording. Captured with my smartphone's voice notes app. There's also some human voices in the background, possibly from another room or a tv.

I drove my car into a wall; and recorded the proximity alert from it. I then washed it through audacity; slowed it 23%; and trimmed the edges. The result? -chilling. A few indistinct gulps cool the atmosphere a little more. It's not the making of a corpse - but it sounds a bit like it?. Recorded late at night in my car by my home with the engine off in fog - so the sound is 'hollowed' by the atmosphere. Recorded using a sennheiser mke300 'shotgun' mic. Cropped in audacity; and saved as aif file. What a chilling way to go. . . ?.

A low slow pulsating drone. Would work well as a ufo sound maybe?.

A sci-fi sound i made by heavily processing an extremely fast drumloop in fl studio. The kick sample i used is royalty free, created by markus hakala, and obtained from howtomakeelectronicmusic. Com.

Exterior air vent/pipe creating low pulsating dark tones, could be used for creating interesting drones.

A "lub dub" heartbeat sound made with a microphone rumble and various effects and filters.

I installed in december 2011 my sound data for bfd-eco, an acoustic drum vst that really rocks. By that time i had my akai mpc 1000 connected to my computer to do some sampling. While i didn't do any sampling while the installation progressed i did hear that the external hard drive that i was installing onto sent out disturbing binary pulses that my mpc picked up. I quickly started the sampler, and recorded as much as i could of the noises. This is the result.

A sonar-like drone pulse created with onlinesequencer. Net.

This is the digital belgian railroad crossing alarm sound. The belgian railroad company infrabel replaced all the mechanical bells at railroad crossings with a pulsating digital sound that they claim to be more efficient and safe then the previous analog bell sound. Infrabel made this recording available online as part of a media campaign about the replacement.

A single shot of what could be an electromagnetic pulse for some sci-fi videogame or video. Made in ableton with layers of synths, reverb, lfo and chorus. Completely free to use.

A neighing theremin pulse.

A heart beating.

A heartbeat sound i created. Fairly consistent through most of it, and then speeds up into heart-attack mode about 30 seconds from the end. To make it, i took a kick-drum sample and a snare-drum sample, and made a pattern of kick-snare, kick-snare, kick-snare, over and over. I then eq'd them to be less distinct and drum-like, added tape saturation to increase the low-end thumping, a small chorus effect and some compression to get rid of the drums' attack. . . Basically just over-processed the hell out of it. Then i used a plugin called wok m-st to get a fake hard-panned stereo effect. My goal was to make it sound like your heartbeat sounds in your ears when you've been running too fast for too long. I think it sounds cool.

Recorded with fl studio 10.

This is a rather simple one, compared with 002, the sounds are more subtle and less punchy. The bass drum is much significant compared to 001.

The mitosis pack is a pack generally founded on just 1 beat pattern, the most common dance drum pattern found in techno music and trance. This pack uses the single pattern and expands upon it through various sounds that make the pattern sound different. 001 is the basis of all. Reaktor - arobic was used to mainly create this loop.

An acidental heartbeat i made.

A heartbeat sound i made, complete with some gurgling, blood-rushing sounds. Just uploaded a version without the gurgling, in case you prefer the way that sounds. To make this, i took a kick-drum sample and a snare-drum sample, and made a loop of kick-snare, kick-snare, kick-snare, over and over. After that, i eq'd out the more drum-like parts of each sample, added reverb to dull it, a chorus plugin and some compression to remove some of the drums' attack. . . Basically processed the hell out of them. To get the blood gurgling sound, i filled a water-bottle almost all the way full and turned it sideways, so i had a massive air-bubble floating around. I then tilted the bottle back and forth in front of my blue yeti usb condenser mic, so you could hear the air-bubble swishing. I had to be pretty gentle, because if you rock the horizontal bottle too much, the bubble moves too fast and makes a fake-sounding "gloomp. ". When i was happy with it, i mixed the heartbeat sound and the gurgling sounds so they'd work well together. Both the sounds were in mono, so i used a free plugin called wok ms-t on both of them to create a fake hard-panned stereo effect. I wanted it to sound like you'd been running, and were hearing the heartbeat in your ears. I think it turned out pretty cool. .

Sound that can be used for a game, also useable with dj scratching sounds perhaps.

Lots of strong bass on this set. The bass sound was produced by lowering the frequency to about 20 on reaktor - arobic. Amazingly, it sounds fun.

Maybe this is a bit too loud. The overdrive and the crazy percussion instruments adds a bit too much on this loop. I think it needs to be refined.

The bass melody was produced by applying a modulation to the frequency of the bass. Not much has changed from 003.

This is a variation of the loop: 005 from the mitosis pack. The odd bass sound (or melody) is the result of tweaking too much with the modulation.

Back to a normal loop. This loop contains more noise. . . Though they sound like a rough shaker in the background. The bassdrum is slightly not prevalent.

The mitosis pack contains several loops with melodies. I removed the modulation and let the bass run without changing a pitch for this loop. See also loops 005 and 6.

This one has an extremely thick bass that pulsates crazily. At the same time, it sounds like a low tom sound.

I changed the synthesizer's ranges and played a bit with reaktor's structures until i realized i was playing with the frequency range. The result is a radically different sound that sounds more like a machine.

Back to normal. Nothing really special here excepting the unusual tom sound that seems out of pitch.

Finally, another normal loop. Nothing much again, but the difference is significant.

Beautiful sounding minimalist classical piano piece. 2 pianos laying out a hypnotic interlaying rhythm.
