256 Royalty-Free Audio Tracks for "Frequency Sweeps"

A drone sound i created using a dsi mopho, recorded in logic. I didn't use any fx. It's a filter sweep with some resonance and lfo 1 is modulating pan position.

A fast building white noise with added filter sweep and fade-out, layered with a pulsating synthesized bass tone with a slow attack and an affected decay.

Created in labchirp using a noise and frequency up.

Made with music maker's digital keyboard and dn-1 virtual synthesizer. A deep, dark, foreboding sound with a pinging signal sound in the background.

Test of how uoki-toki polivoks vcf handles sin-wave (ca 270hz) when the filter is self-oscillating. I bring the uoki-toki polivoks vcf to self-oscillation and tune the vcf to ca 270hz too. I let the lfo sweep the frequency. Cv1 pot at ca 100%. Hmmm interesting. . . .
