326 Royalty-Free Audio Tracks for "Program"

waltz by Chopin (Op. 64, No. 2). According to the little book in the CD cover the piano is a "Steinway grand". Paderewski was very associated with Steinway, he and William Steinway together created the program called Steinway Artists.

This is a drum sound i've synthesized using the great free (gpl) synthesizer zynaddsubfx. Arranged and rendered to 32-bit float wav @ 192khz using lmms (linux multimedia studio) - electronic music production program. Divided into separate files and converted to 24-bit flac using audacity. Please read the pack's description:http://www. Freesound. Org/people/unfa/packs/11746/.

Series of house door sounds starting with several knocks, followed by door opening and then shutting. Mono close-mic recording done with a stageworks ld1 @ 96k/32bit floating. (this file can be multitracked with the other ortf file in this package. If so, do not edit time wise any of the two files before importing to a multitrack program. ).

I was messing around with my korg volca keys, and i liked this little section. The only problem is that i believe it only recorded into the left channel for some reason. I don't know why that happened, so unfortunately you will have to correct that, but it should be an easy fix in any sound editing program.

Recorded with zoom mkh416, in los angeles. Street noise with fire crackers. Traffic and people can be heard. Audio has not been edited. Beware fireworks if wearing headphones. I can't remember what mark the fireworks occurred. Bring the file into an audio program and you'll notice the peak immediately. Raw audio, no filter applied. Use freely, credit name. 2021.

This is the original 8-second drum loop that i ran through akaizer for my "sci-fi ambient drone" upload. It's creative commons cc0, so please treat it as public domain. You can use it in any commercial or non-commercial media for free, no restrictions. I took a quick 8-second drum loop from my teenage engineering po-33 (ko) and ran it through a free time-stretching/pitch-shifting program called akaizer. This program is based on old samplers like the akai s1000 that had extremely artifact-heavy time-stretching and pitch-shifting features. If you slow a sound down enough, the final product tends to sound harsh and electric. Akaizer turned my 8-second drum loop into 2 minutes and 38 seconds of harsh, bassy noise. As you can hear from my other uploads, the results are so different it's almost unrecognizable. Definitely worth trying yourself!.

I only combined them, added some hissing to simulate radio quality and ended the news music early, without the final effect, to be more subtle. Please use the licence (give attribution) to the the main sound, the last linked from connum. Thank you. _____. Port: alguém come uma maçã, liga o rádio e toca a música de abertura do programa de notícias. Eu apenas os combinei os sons dos links acima, adicionei chiado do rádio e terminei o som da música antes, sem o efeito final mais destacado, para ser mais sutil.

A small music sample designed to create an eerie slow-motion effect. It can be looped but has a blank space at the end that would need to be cut off; you can request for me to do it and upload as a separate sound. Created on the music-making program "musescore"; contains bass drums and triangle.

This is a bass sound, not tuned but it is a perfect loop withouth clicks. It has no panning effect - i will do that on another sample. It is not tuned - use a program that tunes the samples to tonal. You must use it only in one octave from c5 to c6. In other octaves sounds not like a normal bass.

Inspired by the main intro theme for the 1980's show airwolf! this loop is played in key c. You can likely change the key in your audio program like audacity. Need a retro intro to go with that? check out my gig on fiverr where i make retro, 80s, vhs intros for youtube and more: https://www. Fiverr. Com/share/2w4znr. Thanks!.

Old work, sorry there's no more. Wav version of this. Digitally made, though i can't remember what i exactly did. . . Probably clicked a few buttons and pushed my keyboard around a few times 'till something happened in my program (was it even running when i did that?). Enjoy :).

Glitchy robot scream, made for a game with robot enemies. I made it by using audacity's "import raw data" function to import random program files which creates all kinds of crazy noises. (all the sounds in this pack came from the files of an emulated ps2 game. ) i then put a vocoder on the sounds i found to make them sound even more robotic.

Just a melody in the spirit of the middle ages, folk, something like that. I tried to make harmony not too strict. You can use it in the game e. G. During the teleportation to the location like a village, a farm, etc. I sketched it in "musescore 2" when i downloaded this tool. Exported direct to flac. This is a very handy program for creating music and arranging.

This is a tune i've made out of a short saxophone riff (using edirol orchestral vst) which i've pitch shifted and reversed and reverbed and stuff and i think it sounds a bit 80s and very much like background music for some sort of tv program or film with spying or detectives or ghosts or possibly straight horror.

Another sound effect for when a user clicks on an button in a menu; this one has a sci-fi effect to it. It has two different "click" sounds, i should soon upload a sound effect with just a single click. Enjoy!. Have a great day!. P. S. I request that all my sound effects only be used for clean, appropriate media and projects. Thanks!.

There is a new freeware program called splitte. Aithat will take any piece of music and extract parts from it. It is highly inaccurate when trying to really accuratelysurgically remove, say, bass, drums, guitar or vocal tracks,but it creates some really trippy artifacts. All of these sample were from a live jazz tune that we were playing. The results of splitter splitting the tracks were really weird and ethereal. I have no affiliation with splitter. Ai, by the way, i just stumbled on it thisweek.

This is a simple sound which can be used for wrong actions or to show failure. Might be used for games or apps in general. The sound was created using the program tuxguitar v1. 2. You do not have to give me credit of any kind. I think of this work as a simple but important contribution to the community. However, if do you wish to tell me, i would be glad to know how this sound was used in your project!.

Sound synthesis made from chuck programming language. The model is a connection from an impulse generator to 40 digital filters to 40 delay linesand set feedback between each delay lines. Each delay lines's delay time and cutoff frequency is random. But there was an error in the calculation and the output value overflows. And this create a chaotic behavior in this sample. - - -. This one is a smooth rising soundwith alternating digital aliasing resonances at the end.

This is the sound of brownyan noise, made with audacity program. Stereo of this noise created with amplitude at the default value, also with fade in and out effects added for the good results. Using headphones is the best way to hear low frequencies of this noise. Also this sound can be use for tinnitus problems or masking unwanted noises. Also, it's very effective for relaxation, sleep or meditation. Enjoy it, and download this is recommended due to the bad quality preview.

Td-3-tg recorded with zoom h-1. Td was performing slide through octaves with "slide" button pressed in program, and subsequent cs were played, in octave -1 and 0, and higher c in octave 0 and +1, back and forth. Program takes 7 16th notes and the space between notes takes 9 rests. Tempo of the td-3 was set to maximum and the volume control was set to high amount, to let zoom h-1 with rec level setting to 37, be driven up to -6db. Sound recorded in 96khz and 24bits. Trimmed and saved in flstudio edison, what made sound 32bit. No amplify, no normalisation. "tune" knob of td-3 was set to maximum as well as "cut off", "envelope" and "accent". "resonance" and "decay" was set to one o'clock. "waveform" swicth was set to square. No distortion. Zoom h-1 was plugged by a cable, td-3 output to line in. Cable was named vitalco - 1/8 inch trs to 1/4 ts, male to male, 3m.

This is pink noise, made with audacity program. I decided to record this in a stereo track and i made this noise for 74 minutes long. The effects i chosen for this sound are fade in and fade out only, with the amplitude of pink noise sets to default settings. You can use this sound for your relaxation session, or if you have problems with tinnitus. For a best experience, you can use headphones. Enjoy it, it's my first sound i created.

The raw data is result of this command in my linux command line shell:. Cat /dev/sda1 > my_hard_drive. Then the file my_hard_drive has been imported as raw by audacity sound editing program with attributes:. Signed 16 bit pcm with no byte order 2 channels (whatever. . . ) stereo, 44100 hz. This sound differs from that which can be played just by command "cat /dev/sda1 > /dev/dsp" - this last command plays sound through speakers instead of writing a file. The sound is closer to sound of 56k modem. Later i will upload it (i've just connected line-out of sound card to it's microphone slot).

This was hella tough to make! and i used this program that turns picture into sound. It has paint tools, and you start with a black canvas, you draw up a pattern on it, and depending on the color, position, size, quality, format and translucency of the marks and lines you placed, you get sounds. But it is really hard to get a hang of! this took me 3 days to get it right! please comment and rate, i worked really hard on this! by the way, i'll be making more of these, so if you like it, then i have three more.

This is a beat that i made in the audition editing program using two free sounds: a cat purr and a water drop. I have no use for it because it's too slow for the songs i usually write. I would love if you gave credit, but i want to leave it as public domain in case you can't for some reason (using it for a school talent show, in a commercial, ect. ) it's frustrating to find the perfect sound and realize you can't use it for what you want to :) if you want to be kind and credit, my name is misgee dreamerheart.

This is a plasma pulse engine for spaceships, hover bikes/ boards, etc. The engine starts up at 00. 000 ms. Then stage one starts at 02. 400 ms. Stage two at 04. 800 ms. Stage three at 07. 200 ms. Stage four 09. 600 ms. Then the engine shuts down starting at 12. 000 ms. To change "gears" set position to the stage start then play. To "run" in each stage loop from start time +. 144 to stage end time(next stage start time) -. 083. You may have to figit the numbers. I haven't actually tested any of this. I don't really program any more. But, in theory it should work.

It's me saying some words. I've recorded my speech and then used ardour's (http://ardour. Org) looping funtionality (which have proven to be rock-solid) to perform theese glitches. I used my mouse to select random ranges in the session, then used the "]" key to set tre selected region as a loop range. And also used "l" key to start looping if i accidentaly clicked on the playhead (which makes it stop playing). I also used space bar to break the loop into normal playback. There was a limiter in ardour. Recorded the performace using jack_capture cli program. I cut out some silence using audacity and converted the recording to flac.

The Liberty Bell march, by John Philip Sousa (1854-1932), played by the New York Military Band. Recorded on Edison Blue Amberol cylinder record #3220 (unrestored version).The march is often associated with the British TV comedy program Monty Python's Flying Circus (1969–74), which used the piece as a signature tune. Nevertheless, the march remains popular with British military bands. Der Freiheitsglockenmarsch von John Philip Sousa (1854-1932), interpretiert von der New York Military Band, aufgenommen auf Edison Blue Amberol Zelluloidzylinder Nr. 3220 (Unrestaurierte Version).Der Marsch wird oft mit der englischen Comedy-Show Monty Python's Flying Circus (1969–74) assoziiert, die ihn als Titelmusik einsetzten. Dennoch ist er nach wie vor bei britischen Militärkapellen beliebt.

This sound was created as follows:. -zynaddsubfx free (and insanely amazing) software synthesizer generated simple g tone using a sine-wave adsynth engine- creative sbs 250 speakers played it back distorting the sound naturally and adding some interesting stereo phasing effects (is that caused by analog signal cable being longer for one speaker?)- i was manually changing the volume using the speaker's potentiometer (whitch is dirty and added some interesting noises on the right speaker, and also at peak loudness during the 54th second the right speaker is quiet)- the output was captured by zoom h2's rear mics- and recorded via usb into audacity free audio editing program- i exported the recording as 16-bit flac.

This piece was produced using a text-to-speech program on a "rant" by francis e. Dec. Mr. Dec was a disbarred lawyer from new york state who spent the balance of his adult life writing and publishing rants against a global conspiracy that had removed him from the legal profession, controlled the white house for decades, performed clandestine medical operations on the entire population of earth and worked for a malevolent entity called the "world wide communist gangster computer god". Mr. Dec appears to have hated just about every religious, racial, ethnic, professional and political group that he was aware of. Although i have tried to maintain the syntax and general flow of this rant; i have taken the liberty of removing the more offensive passages and phrases. Since the development and widespread use of anti-psychotic drugs in north america, schizophrenic creativity of this level of complexity has become harder to find. Street ranters are an endangered species but my memories of them include the unusually stiff, declamatory and repetitious cadence of their speeches. Curiously, a speech-to-text program mimics some of these features. I hope that the irony in using a computer voice cuts two ways. Mr. Dec's rants are in the public domain. To his credit he was very open source with his work. My use of dec's writings should not be construed as advocacy for his views nor as an endorsement of how our society currently treats persons labeled as schizophrenic. The wikipedia entry on francis e. Dec is a good and balanced starting point if you are interested in the life and work of this very unique and unfortunate man. I leave the listener with this quote by g. K. Chesterton-. "the madman is not the man who has lost his reason, the madman is the man who has lost everything except his reason. ". --.

This, my dear friend, is ils - infinitely loud silence. Play some other sounds and then play this, and you'll know why i call it this way. It's created by a bug present in lmms, a free program for electronic music production. Actually this sample can't reproduce the ils phenomenon, that creates a dc offset so big, that it outnumbers any other signal getting out of the same audio interface and the result is silence. It's a silence that is masking other sounds. Mind-boggling. Nasty bug. All this sound can do is cause some distortion, probably because 24-bit sound can be only as loud as 0db. 32-bit floating point should be able to get louder, but still i don't think any sample file would be able to reproduce this product of error.

This is a precise emulation of the audible time signal broadcast by radio station wwv of the nist in the usa on shortwave. This recording was produced via a program i wrote that emulates the time signal and recreates it from scratch, but it conforms precisely to the specs of the real signal. The only part missing is the voice announcement of the time, which, in the real broadcast, is made during the last fifteen seconds of each minute (which is why the tone changes to just clicks during that time). There are two minutes in the recording, but it should be easy to loop it or otherwise modify it for other durations. Since this audio file was computer-generated from scratch, it contains no noise, but the real broadcast has some static and noise, especially at large distances from the transmitter in colorado. Generated by special software / 48. 1 khz 16-bit stereo.
