1,135 Royalty-Free Audio Tracks for "Dual Tone Multi Frequency"

A recording of a backroom with the extractor fans running, the audio is low in pitch and can be used in instances like machinery rooms, all of my sounds come uncompressed or processed. This means there may be unwanted background noise/ sound that you can remove or not at your will. Equipment used:. Tascam dr40 w/ built in stereo microphone. File information:48,000hz24bit wavstereo.

A simple ringtone from star trek: into darkness created with after effects. It was simply a sine wave produced in adobe after effects, edited with a few volume adjustments.

Uploaded 4 sounds for a blog post. All the credit goes to benboncan - chopping noise, tliedes - match noise, jace - boiling bubbles, and zacharymark920 - silverware. I only put them together in audacity for a blog post for a class. Under fair use of being a student.

A dark moody sonic phrase.

Virtual analog synth mixed with analog ea-1 to create this wind like pad. Sampled through a behringer mixer into an mpc 1000. It sounds nothing like a wind section, hence the title broken wind. 44. 1k, 16-bit.

This was made with kontact and a korg ea-1, mixed with a behringer mixer with light dirt and overdrive. Sampled into an mpc. Left and right are separate channels processed differently. So each sample is actually 2 different sample, 3 if you combine them. 44. 1k, 16-bit.

Dave smith's mopho analog synthesizer's triangle wave sampled with an mpc through a behringer mixer. 44. 1k 16-bit.

Medium room with some light rain outside the window. Minimal eq applied.

This sound is an audio file that slowly breaks up the further it is played. I recorded this with an in-built microphone, no idea what make though. I recorded this on audacity, and added gradual distortion. Warning: you may need to turn down the volume for the last 6 seconds!.

A very high pitch noise from ddlc.

This kind of noise randomly generates the values -1 or +1 at a given rate per second. This number is the frequency. In this example the frequency is 100 hz. The algorithm for this noise was created two years ago by myself in c++, as an imitation of noise generators in supercollider 2.

This kind of noise generates sinusoidally interpolated random values at a certain frequency. In this example the frequency is 100hz. The algorithm for this noise was created two years ago by myself in c++, as an imitation of noise generators in supercollider 2.

Recorded in a tram in tokyo. I didn't use high-pass filter when recorded, so i think you can hear much low frequency. Sennheiser mkh20 and fostex fr-2.

The interference produced at the low (left) end of the radio dial on a jambox set up close to a dvd burner while in operation. Sound rises and falls as the burner writes to disc.

This was produced by tapping on a stethoscope which had an earbud pressed against a shure sm57 mic. Low pass filter applied, as well as compression and a gate. Chorus added. Used a recording cassette deck as a preamp going into an m-audio audiophile usb soundcard. Note: if you're having problems listening to this clip, the cutoff frequency of your speaker set may be too high(solution: new speakers). The signal strength exists almost entirely in the very low frequencies, so you may need a sub-woofer to hear it. Otherwise, try turning your speaker volume all the way up. Doing so may saturate the signal and at least allow you to hear the harmonics of the signal caused by the distortion. I don't recommend it, but you'll at least maybe be able to hear something.

Re-edited sound of file 273410. Lowpassfilter / hi-cut above 60 hz and cutted sub frequencies below 60 hz. Postproduction and editing with sony soundforge, 2015.

A recording and manipulation of radio am frequencies.

Static with pops from dead air on a radio station. Starts with a drone which fades from the background.

A very harsh section of static with periodic interference (source unknown) from the far right-hand side of the fm radio dial, at 106. 7 mhz. Recorded from a digital tuner.

A less harsh, almost tickling of static pops from the right-hand side of the fm radio dial, interspersed with harsh interference (source unknown). Recorded from a digital tuner.

High-pitched flip across the am radio dial. Good intro-type recording.

A metal key attached to a magnet with its handle only. The key bounces back and forth, when pulled back and released, and produces a nice metallic sound.

A modulated bass guitar sound.

A modulated high frequency synth created using eq and vol automation un-filtered.

High frequencies repeted sound (sound design in protools).

A simple sine wav with frequency changing according to a parabola.

Frequency modulation tone of a modular synthesizer.

Static from a radio station wireless remote.

Radio frequency tuning noises.

Very strange sounds from a very high frequency.

We hear the bell of a buddhist master called zoltán cser. We observe in the sound, the space-filling ability of the sound, and the joy of ringing. Dril-bu (tib) ghan-ta (san) bell (eng) csengő (hun).

This is a "bell hit" i made. All my recordings are made by me and 100% free to use wherever you want. Enjoy!.

A highly-modified shepard tone. Reversed, inverted, reverbed, added bass with lowered treble, and to top it all off a highly resonant wah-wah sound effect. All made in audacity.

I recorded a mouth noise. I add reverberation effect where i pick a big room size and a reverberation of 50%. Then, i add a melt opening. I generated a risset drum to create my ringtone.
