139 Royalty-Free Audio Tracks for "Amplitude"

Flip across the am radio dial through a range with some high-pitched sing in the static (and intermittent indistinguishable voices).

A sine wave pushed through some outboard to trade in some fundamental frequency amplitude for higher harmonics - hence the name.

Static from 750 khz on the am radio band, with a faint traffic report in the jumble.

Recording of the 560 kilohertz frequency of the am radio band. Has a high-pitched singing whine in it.

A short section from the 570 kilohertz area of the am radio band, static with obscured talk radio voices in it.

Buzzy patch of static from the am radio dial slowed and with a filter and some digital reverb.

500 hz tone or 500 hz sine wav sound effect. Ear piercing.

Section of am radio static with a high pitched sing in it, from the 580 kilohertz mark of the bandwidth.

Static from the 810 khz frequency of the am radio band recorded from a digital receiver. Has a sort of submarine suggestive hollow quality.

Static from the 760 khz mark of the am radio band, with spikes to the high side of the tone and very little bass.

This sound of alarm clock was entirely made with audacity. First, i generated a sinusoïdal key at 575 hz with an amplitude of 0. 11 during 3 seconds. Then i deselect my track and i generated an other sinusoïdal key at 1500 hz with an amplitude of 0. 33 during 3 seconds too. I deselected the track and i generated a final sinusoïdal key at 2800 hz with an amplitude of 0. 56 during 3 seconds. Next i selected my 3 tracks and i clicked on track - mix and render to a new track. I added a tremolo effect with a reverse serrated and a degree of 0, a level of 100 and a frequence at 25,0 hz. The wave must looks like stuck triangles.

Simple phrase in concert g dorian with a clearly ghosted note around the 2 second mark that shows up clearly when viewing the amplitude or spectrogram.

Buzzy patch of static from the am band of the radio dial. Slight flipping of the dial through the area adjusts the sound.

This is a sample of an ibanez edr470ex recorded via amplitude vst software amplifier. This was the first recording i made after purchasing my emu audio interface.

Signal from a poorly tuned a. M. Radio station on a digital receiver, so no waver to the tuning just the sounds of a distant signal capturing mostly interference from the ionosphere.

I created a sound by playing with its envelope then i cut it and repeated. Then half the time i insert a linear sinusoid noise at 440 hz and 0. 8 amplitude.

The is a constant electronic drone generated by a program i made for the purpose of creating this tone. The tone is clipped and has random amplitude variations.

Radio frequency interference at the 1200 khz mark of the a. M. Band, caused by varying proximity to a laptop computer. Very active and obnoxious high-pitched static and squeals.

Dead air on an a. M. Radio station while lightning in the area "tickles" the frequency to create static peaks. Perhaps similar to the sounds of a radiation or metal detector.

Very weird and extraneous synth sound, basically a square wave with distortion and a high pass filter, have some lfos that modify different parameters such as amplitude, cutoff and resonance.

An ambient steam sound i made for a project. It is made with audacity and is a pink noise with 0,3 amplitude with a phaser. I made this myself and you can use it wherever you want.

I created a dtmf tone with an amplitude of 0. 8 and a tone/silence ratio of 550 and during 7s. Then i amplified 1. 3 db sound. And finally i multiplied the speed of 0,960.

Static from 1010 on the am band of the radio recorded from a digital tuner. The jumbled noise sounds like a harsh wind with an old school chattering satellite chirping away.

What effects the color of the wave here on freesound? i could ask, but here is a little test. Part 1 - a (about) 60hz tone going from sinus to triangle (vcv-rack vco-2)part 2 - same tone. Sinus wave. An accelerating vibrato. Part 3 - now 2 tones. Same 60hz sinus tone plus another sinus tone slowly increasing in frequency creating beating effects. The second, rising, vco has a lower amplitude. All three part has the same peak amplitude (-4db)#colortest.

Microphone: zoom iq7 with simple windscreen not edited stereo 120deg. Baltic sea: calm sea, waves about 20cm amplitude. Best filtering for wind-noise: high-pass 125hz to 150hz / -18db/oct.

To create this sound, i created a sinusoid of 500 hz and an amplitude of 0. 8. I then multiplied the speed of 0. 750. To get this final sound is to duplicate the sinusoid several times.

I created a sinusoidal sound of frequency 200 hz and amplitude 0. 4. I played with the sound envelope on the sides and the middle then i repeated it to create a radioactive sound.

Same sound as connersaw8's "coach whistle," but the factory noise has been removed from the background. Additionally, the amplitude has been dropped a bit with a touch of reverb thrown in to round out the ending.

This sound is a smooth square with a 400 hz frequency and the amplitude is 1. I added a 2 echo with 0,6 decline factor. There is a fade of closing down studio.

A little patch hard to balance. It's a meditative timbre practice. . . A en envelope generator in quadrature mode is controlling the amplitude. Download and take a look at the wave - close. Nice!.

The next sound was recorded in a bathroom which was an open tap with medium pressure. The sound was recorded with zoom h4 handy recorder stereo using the built - in microphones and was modified amplitude and compression.

Sound of a male cat purring while laying on a bed. Recorded on a tascam dr-100mkiii with an audio technica at875r shotgun mic in 24/48 mono. There was a slight modification of amplitude using adobe audition.

This kind of noise consists of only values -1 or +1. This produces the maximum energy for the least peak to peak amplitude. The algorithm for this noise was created two years ago by myself in c++, as an imitation of noise generators in supercollider 2.

This sound was made with 3 lfos, 1 vco and 1 vca. It was decided that the sound should be 30s. It took some tries for me to set the lfo that controlled the vca. The vca controls the output amplitude of the sound.

Dove: the cooing of a dove is achieved through foley. Vibrato is added to an almost owl-like sound created by blowing air into ones crossed-over hands. It is a subtle cooing and varies in tone, tempo and amplitude. Recorded with the zoom h6, rode ntg.

For this sound, i generated a square wave at a frequency of 440 hz and an amplitude of 0. 80 and a duration of 1 second. I choosed the following effects:1- wahwah with frequency f=1. 5hz , amplitude= 70 %, resonance = 2. 5 and offset frequency = 30%2. Repeat3- compressor (x2)4- fade in (half of the sound)5- fade out ( the other half of the sound)6 - phaser with 10 phases7 - paulstretch with the stretching factor=5 and resolution = 0. 258- echo with 1 second delay , decay factor=0. 59 - cut (to arrange the sound). After all this effects, the sound is like a sound recorded in space with echos.

This is the sound of someone tapping a keyboard (dell) in the library of the upf campus of poblenou, barcelona. The sound is repetitive with low amplitude. It was recorded 14:00h. Recorded using zoom h4, normalized with audacity and adde fade-in and fade-out.

Clipping nails: you can hear the subtle click of a nail-clipper cutting down nails. A few options are available in track and they vary in duration, tempo and amplitude. Recorded with the zoom h6, rode ntg in a sound studio. Can be used in any make-over montage.

This sound was created using audacity. With it i opted to show you what is the effect of 440 hz sound with an amplitude of 0,8 on our body. It’s a sound creating disorder and is even difficult to listen to for a long time. This sound was created using audacity.

Ce son est de type x (continu complexe), il est un son seul tonique et terne. L’attaque au début est graduelle et forte. Le son est dense, profond et intense.

The sound of thunder without any rain or wind. Sounds really far away. Could be used as war sounds far in the distance too. Recorded from a storm simulator with the rain and wind sounds turned off and thunder sounds set to highest amplitude.

Opened tracks and added new stereo track using audacity, generated brownian noise with. 9 amplitude and applied equalization effect removing all frequencies below 30hz and above 80hz to -120db, applied bass and treble effect increasing output volume 5db, applied limiter effect using soft limit and limit to -5db with a 20ms hold to remove spikes.
