8 Royalty-Free Audio Tracks for "Image Synthesis"

This is made by feeding homemade images to audiopaint 3. 0 while its oscillators are tuned to randomly-selected scales. Some of them use sine waves, while others use custom waveforms.

This sound will generate the grinning meme troll face in an audio spectrogram. Nice little easter egg.

An ambient sort of sound done by doodling around in photosounder. Using the white spray with the harmonics on i drew two squiggly lines across the image horizontally, then flipped the image 90 degrees counter-clockwise, then with a wide dark brush i darkened some areas of the image to make the sound progress for a narrow band continuous noise to a full bandwidth squiggly kind of noise.

Automation underwent 17 parameters in the modulation matrixsynthesizer toxicbiohazard (image-line).

Synthesized string ensemble short. Long decay, wide stereo image. Made to help you build tension in your amateur movie. Synthesized with zynaddsubfx inside lmms (96khz/32-bit). Edited and normalized with audacity, then saved as 24-bit flac.

Created for a trailer for a film. I used a grandfather clock for the main ticking of the hands but layered and added other sounds such as a heartbeat, hall kick drum with reverb and synthesis techniques. Please note: the ticking by note be in sync if you use and a countdown image i had to move the ticks to accommodate the wall clock i was working with due to the ticks where not always in time.

My fmc002 submission!. For this, i generated several sounds from audiopaint (free software) and spectrobits (free vsti), two image->sound synthesis softwares. These sounded interesting but i wasn't sure how to use them. Then i made a drum beat, synth bassline, and some other stuff, rendered the song, used paulstretch to stretch the song out 4x, put it back in the project, added even more stuff to other tracks (mostly timestretched versions of my own samples), rendered the result, brought that render back into the daw, and then reversed it. A lot of effects and automation were also used during all 3 stages of the track's creation. Further, each time i rendered, i used the same mastering chain, so eq and other stuff is being applied multiple times. This brings out some surprising timbres and overtones. Really, the final recording sounds nothing like the sounds i began with.

Noise created by individual oscillators, using audio paint, with different height images, to demonstrate what happens with too few oscillators vs. Plenty. In the end, the result is not random enough to be noise. The first 2-second burst is pure white noise for comparison. Then we have multiple 1-second bursts from audio-paint in a sequence of different image sizes: 50,100,150,200,250,350, 500, 700, 1000, 1350, 1750, 2200, 2700, 3250, 3850, 4500, and 9999 (this corresponds to the number of oscillators). The last burst is longer, and there is 1/2 second gap of silence after the first (reference) burst and before that last (9999) burst. The images other dimension was 20. The spacing of frequencies was exponential, between 40 hz and 18 khz. This is not intended to be useful, just an illustration during a discussion in a forum (http://www. Freesound. Org/forum/sample-requests/35199/?page=2#post75605). As mentioned there, i realized only afterward that exponential spacing would be giving me an approximation to pink noise instead of white noise, so the reference burst at the start is not really a fair comparison. Ideally, i would go back and re-do all this using linear spacing, but that's a lot of trouble. :-) i did, however, change to linear to get a white approximation, but that's a different sound i'll upload separately (c. F. Http://www. Freesound. Org/people/zimbot/sounds/242053/). I don't believe you can get true white noise without at least something being random in your synthesis method.
