61 Royalty-Free Audio Tracks for "Amplification"

Whenever i use my usb stick, my computer always makes an awful noise. I decided to record it and see if any of you guys can make anything out of it. To me it sounds like some sort of aliens or robots talking to each other. The only editing done was noise removal to get rid of the fuzziness and amplification to make it a little bit louder. Let me know in the comments if you use it.

The feeding of two hungry cats. Early sounds include tinkling of crunchy food falling into a near bowl and a more distant one, and the munching sounds of a purring cat. Then the snap of the top of the feeding container, and closure of a cabinet door. Two cats (bowmore and munro) the former near and the latter further away then transition to eating wet food. Recorded with the zoom h4 xy microphone pair in 24bit 48k wave, then converted to flac in audacity with a bit of amplification.

I produced this strangely satisfying sound by dropping a watermelon-shaped canning tomato into a dishpan full of water. Have to get that just about right to get this result. For my purposes i needed to repeat it, but you can do that. It's unlikely that two objects tossed into liquid will sound exactly the same, but it's possible to modify one of the two "ploops" by changing amplification, pitch and even to shorten the waveform to make them sound different. If you need that done let me know.

Stereo recording of a train arriving and departing at aldgate east tube station, and another train departing on the other track. London underground trains have rubber wheels and a characteristic kind of rumble. The doors open and close automatically. Faint tannoy announcement in the background, and a couple of electronic warning tones when the doors open and close. Aldgate east station is huge but has a surprisingly 'dry' and 'dead' acoustic so that it is very quiet when the trains have gone. Recorded on a zoom h2 recorder, front microphones, 90 degree separation. No amplification or equilisation on this sample.

This sound is a mix of analog sound and digitally created sound. I recorded the sound of a coffee machine. Then on audacity, i generated a tone and modified its envelope. I changed the levels, added effects as reverberation and echo. I put melted at opening and closing in purpose to pretend something was taking off and landing. At first i wanted to create the atmosphere of a spaceship. But after that it looked more like a vacuum noise. I tried to modify amplification and added again echo and reverberation to make it sound more like a weird ufo.

This sound is completely analog. I recorded the sound of a person who was walking on the street. I chose to leave the noise of the street so that we understand that the person walks outside. I used the effect "amplification" to reduce the noise of the street and increase the sound of step. I made a fade in opening and closing, so that we have the impression that the steps are moving towards us then moves away. At the same time, i played with the pitch of the sound to accentuate this effect.

Stereo recording made in the generator hall of tate modern between exhibitions. The end of the hall furthest from the entrance was empty, so i ran the recorder for a couple of minutes just to sample the reverberation. Because it is a school holiday in the uk, there were large numbers of children in the gallery, especially on the upper deck bridge about 25m from the recorder, and their voices are higher pitched and their behaviour extrovert. The space is large, so the echoes give a lot of atmosphere. Recorded on zoom h2. Transferred to audacity and high pass filter with breakpoint of 180hz used (12db/octave) to remove the hum that is prevalent at this site. +6db of amplification used, so peaks at -18dbfs.

A neighbor of mine might have just peed in his pants if he couldn't shoot off his illegal commercial fireworks before the fourth. So, july first, his manly outpouring of window-rattling bomb blasts echoed across an entire valley. For nearly two hours. I like fireworks. When i go to see 'em. Not so much when i can't get away from them. Sure, i could have gone shopping, or out for a drink. I recorded it instead. This particular explosion is just the largest of those that came after i started recording. It's just a lowly iphone but it does pretty well. Admittedly, even with no amplification it might have been too much for the microphone. You have the clear launch sound followed by burst and echo. The same blast kicks off the other fireworks file i am uploading.

Theme old bombtimer :. Production steps:i record the sound of a book falling on the floor. I copy the sound impact 8 times on the same track. At the end « i fade in closing ». On another track, i copy the first track. I displace this second track on the right with « time shift tool », it creates a shift. I change the pitch of this track with a percent of change of -47. On a third track i take another recording sound of a key knocking on metal. I copy this sound 8 times and put a « fade out » on all the third track. I shift the track to begin at 1sec. Description:this sound look like to an old bomb timber. There is two different sounds one look like a heartbeat and the second a clock ticking. It creates a very stressful sound because of the progressive amplification. The bomb will explode soon and we need to hurry to defuse it. Typologie de schaffer :.

Non-functional tube radio warming up, making a loud 60hz hum with lots of harmonics. As a bonus it clicks off at the end. Zenith consoltone. Only because the faq says so: electro voice n/d 257a through impedance transformer into crappy gigabyte motherboard realtek high definition audio. 16bits, processed at 32bits. Audacity sound editor and/or driver wouldn't record mic level so it was very noisy after amplification. Filtered with a (mathematically equivalent) fft constructed whopping 64k length zero phase filter (blackman window) with 5 wavelength width bandpass at each harmonic from 60hz to 5,520hz. For some reason a fraction of some of the harmonics didn't get through so did another pass on the residual noise and mixed that in. Near the beginning there was a sort of brief duplicate signal that descended in pitch so it didn't make it through the filter. I added that bit in. Attenuated frequencies above 3. 6khz because they are pretty much noise, but removing them didn't sound right. Cleaned up the beginning a bit in various ways, cut it down to 15 sec and carefully appended the unfiltered "click" onto the end, which i denoised 12db with audacity's noise reduction.

This sound is a superposition of two records. First, i recorded a coffee machine and cut it to extract just the sound of the money that falls in. Then, i recorded the sound of keys and mix it together on audacity. I wanted to make a sound that can be repeated in a loop. So, i copied the record of the coffee machine to give a rhythm to the sound. I tried to cut the sound of the key perfectly to make a loop with the help of the option “search for crosses with zero”. Then, i added view effects. I have changed the amplification in purpose to bring out more the sound of the coffee machine. I also change the reverberation. Gradually, my sound made me think of a music in a video game that i used to play, rayman. It was difficult to describe what the sound was like, but i liked the atmosphere, so i kept it. Then, a friend told me it made him think of a frog noise, and i liked the idea. Code typologie de schaeffer : v’’précisions morphologie :sur le principe de l’écoute réduite, la morphologie du son peut-être décrite comme étant un groupe tonique car nous entendons plusieurs hauteurs. Le son peut être qualifié d’acide et éclatant. Le son paraît plutôt rugueux. Je dirais que le son est dynamique mais que l’attaque n’est pas brutale mais graduelle au moment où l’on entend le son de la machine à café. Le profil mélodique présente des variations plutôt scalaires. Pour finir on entend des hauteurs de sons parmi d’autre son.
