347 Royalty-Free Audio Tracks for "No Signal Sound"

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).

This is a fragment from the aria ah mes amis at a lower pitch and badly performed. Iintend to use it for a coursera homework (audio signal processing for music applications). The intention is to transpose it and simulate a morfing like a falseto to the true key where the tenor hits high c, which i obviously cannot hit, otherwise i wouldn't be taking coursera courses and uploading to freesound. . .

These are fake siren noises i made in logic by using es p. The warnings are in the following order: caution (three pulses), alert (steady), attack (wailing), large fire (hi-lo), evacuate (hi-lo/alternate wail). These don't conform to any signal guidelines and must not be used for anything other than a mere sound effect.

Antique hermle fireplace clock bell from the 1950s. One strike. Chord: ab, f7. Long decay time. Recorded in xy stereo from inside the clock. Recorder: tascam dr-60d mkiimicrophone: 2x røde m5processing: noise reduction.

Opening and closing an old slide-up phone and pressing the buttons (with and without tones). Different phone numbers (funny pressing melodies). Dialing tone while waiting for answer. Ringing tone with vibration. Vibration only. Error melody. Message signals with vibration. Alarm tones.

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.

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.

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.

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.

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.

Interesting (but painful) sounds made with a zoom h2 (front mics, low gain) connected to a laptop via usb. The signal was piped to old creative sbs250 spekers with 16ms of latency (i'm using jack audio connection kit and linux). That's how my feedback loop came into existance. I turned up the volume and started to move the mics around, geting a lot of different sounds ranginf from simple tones to strange lfoish sounds. The sound touches 0db one times, but is rather undistorted (at least digitally). Recorded with audacity @ 48khz/16-bit and saved as flac.

A honk repeated and mixed in audacity to seem like a car alarm. Extracted from a video (http://img. Youtube. Com/vi/lsv3rg1ptls/2. Jpg) by a us government agency, thus public domain.

This is a short fragment of one of the experiments done by the music and machine learning lab at mtg (upf). The aim is to develop an automatic violin teacher using ml techniques. Mtg is a research group specialized in audio signal processing, music information retrieval, music interfaces, and computational musicology. This sound tries to reflect the work that is being done there about world music and computation. Learn more at: https://www. Upf. Edu/web/mtg.

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.

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. ;-).
