785 Royalty-Free Audio Tracks for "No Signal"

I wanted to make a sound effect for a game i'm developing, and so i recorded a 100-mm artillery cannon at camp williams (utah national guard), then modified the sounds using audacity. The recording was done on an olympus digital recorder in the mid-2000s (first decade). It sounded a little to me like the tribute cannon from hunger games (the sound effect that signals the deaths of the tributes), thus the name.

A recreation of a lavalier microphone pop. Useful for reality or documentary where an interviewee may rip off their mic or you simply want to create the illusion of that drama. Also useful to incorporate into a "signal lost" effect, etc. Processed with some limiting so it's tamed and ready to throw in a mix. Recorded with an mxl lsm-3 dynamic mic, no reason to abuse my real lav mics.

Small field recording of the singing bridges in tejo river shore, lisboa. It can be heard the metal scrapping coming from de bridges that serve as points of embarking for the boats that cross the tejo river between lisboa and cacilhas, close by waves splashing against the shore and boats sound signalling. Recorded with zoom h4n internal mics. February 2015.

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.

White noise through s&h sampled at audio rate using neóni. Quantised sequenced in mimeophon and dpo using 0-ctrl. 1/2 signal through erbe-verb the other through mimeophon. 10 markers set. Rendered at 48khz 32bit for morphagene in reaper. Enjoy!.

Very devout american radio amateur from ohio praise the lord. He is happy that his friends and family have come through the corona crisis well. It must be very helpful to use radio signals to reach the lord.

This is an editied version of acclivity's sound file, "30832_acclivity_summereveninginmygarden". His original file contains a barking dog, which depending on your usage, can deter from the intent of your project. Since acclivity's recording has excellent signal to noise ratio, and has captured some beautiful birdsong, i thought other people might be able to use this edited file with all the dog barking taken out.

Japanese traffic in the summer: passing cars and tracks and some motorcycles, cicadas, recorded with iphone, nearby crossroad of the six-lane road and a large park in tokyo. First 40 seconds is crossing the six-lane road. From 54 seconds cars in the six lanes start to come toward me and pass by. At the end of the audio, the signal turns to red again. Pedestrians cannot cross this road.

This is a transformation of the original recording https://freesound. Org/people/pinehadmz/sounds/369501/. For week 10 "musical piece" assignment for the audio signal processing for music applications online class. There are three layers, panned in stereo. Each syllable of each layer was randomly pitch shifted to a note in the minor scale using the harmonic plus stochastic model. Each harmonic track was thickened with extra harmonics during the synthesis process too to make it extra weird.

This is static actually coming from my radio but its plugged into the same cord as my tv & they are very close together. So it's actually interference. Also the proximity of my phone gives more sound (ringy static). That really awesome modulating sound is the moment between clicking the on button & the picture coming on the screen. 2nd try was better after i adjusted the tuner a bit.

This sound is a 1-sample long impulse at 48 khz. It covers the whole frequency range with equal power. This is a perfect sample for exciting your guitar amp or reverb unit to capture it's impulse response (ir). You can also play it through a speaker in a reverbant room to capture it's reverb characteristics. Remember that the ir sample will be no flatter than your speaker's performance multiplied by your microphone's performance (frequency response characteristics). The sample has exaclty 1 second of silence, then the impulse, then another second of silence to ensure the impulse will be played clean and untruncated on any sound system or device. My test with ir lv2 convolution plugin have proven, that this sample has absolutely flat frequency response - convolved signal was identical to the source signal. After normalization and sample-alignment of the sound clips i have inverted the polarisatin of one of them and summed them - result was absolute silence, even no hiss was present as a result. This shows the accuracy of the convolution process and proves this sound to be perfect for sampling ir. The impusle was generated with c* dirac ladspa plugin. Created using audacity.

This sound is 50 ms, 2000 hz pure tone with double linear fadeout through it's whole length. Sampling rate of 8 khz is already an overkill (nyquist frequency is at 4 khz, while all energy of this sound is present in narrow 2 khz frequency range). Created with audacity for use with ardour 3, a free and opensource daw for linux and mac (http://ardour. Org).

nonlinearcircuits jerkoff chaos circuit is based on sprott's chaotic jerk equation. This sound is long and boring. . . But i wanted to test the nlc jerkoff. This might be of interest to someone. . . I upload an mp3 file to save disc space. . . The single module has 3 outs. 2 of them are controlling vcaa and one is connected to an envelope follower that generates a trigger when the cv is high enough. The signals in to the vca are the same (1. 5v). A way to illustrate the work of the module. Maybe.

Original file created using steinberg's padshop pro vsti. Heavily processed using reafir from the reaplugs vst fx suite. Http://www. Reaper. Fm/reaplugs/. It's always nice to hear back from you. What projects did you use these sounds for?please let me know. ;-).

An edited version of my upload uke_single_notes. Wav. I shortened that recording to its last four notes, then included a fade out to eliminate most of the non-ukelele sound at the end. This recording has notes as follows: g4 g4 a4 d4. This sound was originally created for the coursera course "audio signal processing for music applications. " i recorded this sound myself with a zoom h2 microphone and a kala classical ukelele.

Broadmoor hospital siren test. The broadmoor siren. Every monday morning at ten o'clock the deafening sound of an air-raid siren disturbs the peace over a large area of the leafy commuter belt that is berkshire, uk. The signal sounds the familiar alternating high-low note, followed by a constant all-clear note five minutes later. It's not a re-enactment of the blitz; it's a test of the escape alarm at the local mental hospital, broadmoor.

The sound of my radio noisy. Recorded within the shooting for my filmhttps://www. Youtube. Com/watch?v=b3nh1acesig. You can use this sound for free. It would be nice if you add this to your credits:sounds by https://www. Youtube. Com/user/diramus. Sound recorded with the zoom h1. Thanks for using ;).

Sounds generated by assigning the "wave out" or "line out" signal of the soundcard to a track in fl, and turnin it up. This acts as a digital delay effect with infinite feedback and a very high cycle rate. Basically the noise (similar to pink noise) is produced by the soundcard and the resonance is produced by the low pass filter and the convolution reverb mapping of the waldassen cathedral.

Birds of paradise displaying in their usual frantic manner. Uses the dpo and edorphin. Es furthrrrrgenerator as sound sources. Mimeo phone and qpas- erbe-verb for effects. Part of signal passed trhrough morphagene, variable grain size and speed. Thanks to the guys and gals at endorphin. Es and make noise. No sponsors, just great inventive people, like all other modular manufacturers out there!. Stay safe and healthy,best,. Jim bretherick.

Electro-magnetic interference from a desktop computer, and an at&t; cordless phone handset cl82301 when held near the internal ferrite antenna on the back right of a 13-year-old boombox listening to the am broadcast band. Recorded 2 years ago so i forget where i was listening. Recorded with goldwave from line-in. You hear emi from the computer at first, then i bring the phone on standby near the radio and you hear a series of nearly pure tones. The phone comes on and you hear a distorted dial tone. I move the phone away from the radio for a few seconds and you hear the computer again, then i bring the phone near and you hear a distorted busy signal. I disconnect and the phone continues sending to the base for a few seconds so you just hear a hum, then the idle tones are heard, then the computer noise as i remove the phone.

A horn sound signaling danger approaching. Gradually increasing, it's basically saying, "oh crap, what is that?" originally recorded on a zoom h2, it's a sound of me humming. Of course it's been filtered, slightly stretched and had distortions of a high degree thrown in and filtered more to achieve the horn sound. Enjoy!.

This is a great recording from my digital police scanner of the atf and u. S. Marshal's doing a short, but detailed road surveillance here in houston. The atf starts out talking about a place to meet, then they follow the target suspects vehicle. Once they lose sight of the vehicle, they decide to let the marshal's signal device, planted on the vehicle, track it the rest of the way. This is a fine example of the new p25 digital (some encryption used) radio system that many federal and local law enforcement departments are starting to use. Enjoy!.

Rndstep generated sample and hold signal of the waveshaped neóni output passed into rings same cv used through dpo, some low pass filtering in qpas, much modulation using øchd, erbe-verb as reverb. Morphagene mix 50:50 1/2 speed, slide position modulated with øchd. Fed into x-pan. Morphagene ready, so get ready to enjoy for incidental stuff etc.

Recorded on mid-summer (that looked like mid-autumn) day 2010 in vilnius with a simple olympus voice recorder. I placed an old piece of metal sheet on a broken glass fish tank near a garage wall to catch the drops, recorder was placed in the middle of the sheet. The rain was very light and fine, later it intensified and became lighter again - all this is heard in the recording. Unfortunately three recorder beeps are heard at the end signaling that it was running out of memory. I later decided to leave them in as it quite unexpectedly added some drama to the whole record. . .

Formatted for use in the make noise morphagene. Seven chords from my fender rhodes, each on its own splice, centered around a bb-minor root. The rhodes was running through an mxr zw-44 for mild overdrive, and the signal was boosted with a focusrite scarlett dynamic octopre.

Recorded may 23rd 2022 at noon for the 70 year anniversary of the first siren test in sedgwick county, kansas. (april 22, 1952). 50-65 feet from the siren. This thunderbolt was installed in 1952 and remained until sometime between 2012 and 2015 when the siren head was replaced with a newer bolt. The original controls and blower remain, however.

Violet aka purple noise power density increases 6 db per octave with increasing frequency over the frequency range. It is also known as differentiated white noise, due to its being the result of the differentiation of a white noise signal. I created this by looping http://en. Wikipedia. Org/wiki/file:purple_noise. Ogg. Which is copylefted, however i claim that they can't be protected based on http://en. Wikipedia. Org/wiki/threshold_of_originality (check language sidebar on wikipedia page for other jurisdictions).

An artistic experiment searching for sound emissions and the limit of human hearing. Composed of infrasonic material that have a low acoustic impedance. Humans will be able to identify tones as low as 12hz. Natural and human produced infrasonic sounds is anywhere, all the time. The artistic idea was to use background noises, signal fidelity, harmonic distortion, low-frequency in order to foster a soundscape of infrasound that travels through space. Made for project that was never released. Think somebody might enjoy or use it.

This jump scare sound was created by playing 2 dissonant chords on a single coil telecaster mic'd up w/ a vox ac 10 amp. The two guitar tracks are panned left and right- reverb and delay are added. Additionally, frequency enhancers were added between 4khz - 6khz which adds a higher tonal energy in the upper range of the guitar. Gain is added which can be heard as signal noise mostly at the end of the clip. Enjoy. Bainmack.

I was playing around with my sampler fx today and decided to rig up my electric guitar. I use a fender american special stratocaster, hooked up to an akai s2000 sampler with on-board fx - distortion and guitar metal applied in real time, the signal then sent through to amplitube fx rack on my computer with vintage crunch setting. This is a strum of the lower e open. I recorded a number of stabs and thought this clip might come in useful.

Clattering about in the kitchen drawer to get spoons out. Getting a bowl out. Shaking a carton of soup up, ripping the top off and pouring it into a bowl. Tapping the carton to get the rest out and then throwing it into the pedal bin. Opening the microwave door, putting the bowl of soup in, tapping out the numbers and then turning the microwave on. Beeps at 1:50 to signal the end then open the door again. Natural kitchen ambience. Wav 24bit 44. 1khz.

Recorded just after the clock struck midnight, signaling the beginning of 2023 in greenville, south carolina with a tascam dr-05 stereo recorder. Very nice clear recording with basically zero unwanted noises except for an occasional light water drip. Audio edited to perfection by me. ;) did some light eq, compression, limiting, and stereo balancing, as well as removing some of the constant ambient white noise hiss. Creative commons 0 license, so use this for whatever you like! enjoy!.

An artistic experiment searching for sound emissions and the limit of human hearing. Composed of infrasonic material that have a lot of harmonic distortion. Humans will be able to identify tones as low as 12hz. From 1000 hz the auditory system decreases. Natural and human produced infrasonic sounds is anywhere, all the time. The artistic idea was to use background noises, signal fidelity, harmonic distortion, low-frequency in order to foster a soundscape of infrasound that travels through space. Made for project that was never released. Think somebody might enjoy or use it.
