968 Royalty-Free Audio Tracks for "Frequency"

Simple 4 beeps same frequency.

A low freq sine wave drop.

Accordion band filtered remix and extracting high frequencies.

Old crt tv high frequency base tone 15,625hz.

Using a frequency filter by setting its oscillations in variable arrays i was able to make most of these sounds. Also vocoding and feedbacks and feed throughs were happening. Then they were altered in audacity.

I made the vcf self-oscillate at a frequency of ca 270hz then i connected a sinus wave vco to cv1 and swept all the frequencies.

Track made for the final assignment of the coursera course audio signal processing for music applications. Sounds from freesound. Org, transformed using sms-tools and edited in audacity.

This is the stereo file of the 4-ch thunder-file--> https://freesound. Org/s/367222/. The thunder is slow downed to 0,7speed and has now very deep frequencies, which can shake your house, if you have the right equipment to play the file. ;-)the 4 channels are recorded in irt-cross technique so it is a 360° record. Ch1(left) = fl+rlch2(right) = fr+rr. _________________________________________________________________used recording gear:zoom f84 x rode nt1 (without "a" = the black ones).

Exploration of deep frequencies.

Accordion low pitch band filtered remix low frequency refiltered.

I've decided to experiment with random frequencies slowly filling canvas and blending into a single timbre. For this piece they emerge with quite an amount of time and there is no distinct frequency to form a tone. This experimentation produces quite a hauinting sound consisting of small parts.

Cutted parts of an audio experiment using carbon electra saws with some internal pitch envelope going on, going into trash 2, going into eq modulation, going into manipulator (formant & pitch shift, a bit fm modulation on a shifting frequency at times), going into ott.

A synthetic synth sound in a few different frequencies.

Short guitar clip. A4 frequency is 432 hz.

A scanning sound for a scanning thing for in games, like a medbay scan.

“hailing frequencies open!”. Computer blip/chirp sounds, for all your science fiction game/film needs. Havefun.

Sawtooth waveform of frequency 440hertz and 5 seconds generated with audacity.

Dual tone multi-frequency (dtmf) dialing 1-2-3-a-4-5-6-b-7-8-9-c-*-0-#-d in this order. Made with audacity.

Static with a sort of jackhammer pace at 107. 9 on the fm side of the radio dial. Recorded from a digital tuner, with a quick flip to 87. 5 fm then back to the 107. 9 static. Definitely qualifies as noise.

This is a recorded sound of nails tapping a fence. The different modification steps :. - fade-out effect- wahwah effect with the following parameters :lfo frequency : 1,5hzstart-up phase : 0 degdepth : 100%resonance : 1. 0wha frequency lag : 10%.

Thick snare drum notch-filtered for mid frequencies.

Static from a radio station wireless remote.

Sub dive, very low in the frequency range.

Warning: low frequencies and dc offsets galore!!. This sound was once a photoshop file.

Created in labchirp using a noise in a frequency of 440hz.

Output sound obtained after frequency scaling and stretching of sound speech-female_hpsmodel. Wav (https://www. Freesound. Org/people/anjds/sounds/377067/) with transformations model implemented in the sms-tools software package (http://github. Com/mtg/sms-tools)parameters considered are:- i) frequency scaling factors = [0,1. 5,1,0. 6], ii) frequency stretching factors = [0,1. 5,1,1,2,1. 5],iii) timbre preservation = 1, iv) time scaling factors = [0, 0 ,1 ,1].

Kick drum created by merging, individual equalizing and compressing two others very different kicks. It works effectivly creating new kick drums superimposing the lower frequencies of one and the higher frequencies from another. Then group then and compress in order to melt them as they sound as one.

Digital manipulation of a sampled bass synth with pitch lfo. Sampling, multiband processing middle frequencies, saturation of low frequencing, filtering and compressing.

Part of special permitted radio traffic on days of the 100th anniversary of titanic tragedy. Czech amateur radio station ok2bvg sending cq on 502,4 khz (medium wave - frequency similar to titanic mgy station used frequency). Received in jn79nd location.

Drone experimenti want sideband frequency 1 (s1) to be 110hzas fc (carrier) i use 164hzthen fm (modulator) must be 54hzcreated s2 will be 218hzslowly an lfo brings in the carrier frequency. This is mono. No fx. All analog. Listen to the electronics.

Sonido ritmico de sincopa alta con un tempo de 120.

Requested sample for a flip across the radio dial. This is on the am side.

This sound was created with layering and frequency processing. Bpm 120.

A model i made in blender imported raw in audacity(warning: high frequency noise).

A garbled sentence recorded from a ham radio repeater frequency in westchester county, ny. Recorded with a uniden bc75xlt, plugged into a scarlett 2i2 interface. Recorded with ableton live 10.

Seamless loop of gaspipe or gasleak hissing continuously. This sound is the actual background noise in the frequency range 1200 to 6800 hz from my randomly generated subhorrorambience1. Wav sample. All frequencies below 1 khz (lowend) and above 8 khz (highend) have been filtered out and the volume has been normalized. I release this sound as cc0. You can do whatever you want with it and don't need to mention my name. Tips & tricks for professional mastering of dark ambient loops:. ~ (range) 1200 - 8000 hz, the highmid area of all sounds. ~ (gate) filtering in and adding subtle noise in this frequency range can addatmosphere or "air" to dark ambience but sound noisy like a tape recording. ~ (filter) filtering out noise in this frequency range can make the bass andlower frequencies (20-1000 hz) in dark ambience sound clearer but more dull. ~ (highend) frequencies above 8 khz should always be filtered out completelyand muted to 0 db, since those are only necessary in music and higher sounds.
