26 Royalty-Free Audio Tracks for "Device Testing"

My typing on a keyboard. The tascam dr-05 is lying on the table in front of the space bar.

Clicky sound and hum after that. Recorded while testing audio equipment with computer. Recording device: samson meteor mic.

Using an analog "buttset" or test-set telephone, clipping the leads from an exfomaxtester device and hearing the tones from testing a line, at a terminal/crossbox location (roadside). Cut some low frequencies and added 2s, 5s, then 3s digital-delay effects automated and a reverb effect.

This is a simulation of the sound produced by the fabyan anti-gravity device which was built, tested and debunked in 1913 at riverbank estates in geneva, illinois. The device is now in the geneva historical society museum but is too fragile to attempt to operate it. This simulation was produced to accompany an asa conference presentation "what did colonel fabyan's anti-gravity device sound like?".

Was testing a bluetooth device on audacity and windows 10 and got a bit annoyed so i tapped it out. Might be useful for something. Hope you like. More about me just put phm. Link into your browser.

Soundtrack made by two tracks of guitar and some delay effects. Recorded with a cheap spanish guitar to test my brand new akg 214. Recorded at home through an avid fast track solo device to reaper.

Ambisonic test recording made with a sennheiser ambeo mic into a sound devices mixpre 6 ii. Recorded in 32bit float. Mic position was 'endfire'. Not too much action but it gives a good idea of how a quiet ambiences sound in ambisonic. You will need the sennheiser ambeo plugin in order to convert this recording into b-format.

Edited a default preset in bk-synthlab's free "vs-1 oscilloscope" synth and hooked it up with a free midi sequencer vst (hyperion) and placed thrillseekervbl on the master. This was done using headphones back then so the sound may not be optimal on some playback devices.

Start-up sound of a u. S. Army m1a1 tank - gas turbine engine. Recorded during civilian parade, tanks for display. Us army testing and displaying m1a1 tank for public. Demonstration of turn on turbine ignition of the m1a1 tank. Originally recorded with accompanying video from device.

A toilet is flushed and then it slowly refills and stops. I'm pretty sure this microphone is rolling its eyes right about now, but i will reassure it this was just a test to see what it did with mundane sounds. Schoeps cmc6-uxt/mk41 > sound devices mixpre-6 @ 24/96 > adobe audition (edit, nr, normalization, downsampling) > flac.

Rode nt4 microphone compare signal-noise of phantom and battery power. Nt4, together with small electrical clock, in bed under all the pillows of the house. ;-). First 48v phantom-powersecond 9 v battery-power. Gear chain: rode nt4 with original xlr cord > sound devices 302 >tascam dr-100 mk2. My conclusion: the battery powered mic nt4 is 0. 5db more quiet. Not very significant. See also; http://freesound. Org/people/klankbeeld/sounds/217695.

Running water into a bathtub. The faucet is audibly turned on and off at the beginning and end. The temperature of the water is tested at several intervals resulting in some variation to the water sound. Individual drips can be heard after the water is turned off. Take 2 of 2. Originally recorded for a short film where one of the characters takes an off-screen bath. Recorded (if i remember correctly) with a sennheiser mkh-416 microphone into a sound devices 302 mixer.

Sparrows flying from branch to branch in a bare rose bush. Unintentional capture of sound as i was just out walking testing new equipment. This recording was made using a sound devices mixpre6ii and a stereo pair of fel em172 mics. Low cut on the sd which in basic mode is 80hz (i think). There is no processing to this recording other than to ‘normalize’ the levels. I do not require any credit or attribution.

This sound is a 1-sample long impulse at 48 khz. It covers the whole frequency range with equal power. This is a perfect sample for exciting your guitar amp or reverb unit to capture it's impulse response (ir). You can also play it through a speaker in a reverbant room to capture it's reverb characteristics. Remember that the ir sample will be no flatter than your speaker's performance multiplied by your microphone's performance (frequency response characteristics). The sample has exaclty 1 second of silence, then the impulse, then another second of silence to ensure the impulse will be played clean and untruncated on any sound system or device. My test with ir lv2 convolution plugin have proven, that this sample has absolutely flat frequency response - convolved signal was identical to the source signal. After normalization and sample-alignment of the sound clips i have inverted the polarisatin of one of them and summed them - result was absolute silence, even no hiss was present as a result. This shows the accuracy of the convolution process and proves this sound to be perfect for sampling ir. The impusle was generated with c* dirac ladspa plugin. Created using audacity.

An unintended recording of me and a passerby walking through very thick and wet mud on the walthamstow marshes. I was out testing new gear and couldn't remove the mics from my rucksack strap to avoid picking up the rustle of my clothing or my occasional heavy breathing.

Coucou !. Some day in octobre 2020 i had to perform as a musicianfor an iraqi theatre play of adel jarallah,they asked me gently & politely to also dosome voice over or guiding voice of the protagonistat a certain moment in the play. . . Which i gladly did, with, you'll never guessthe philips 50's oldschool vintage microphone, that's right !. That sound is something else. I connected the mike to my pedals & amplified itthrough a nice, vintage oldschool farfisa tube guitar ampi had been getting from charleroi, some week before. Charleroi what a city ! farfisa what a sound !. - - - here i'm just testing out the sound devices mix prepreamps together with the philips 50s mike - - - with theexact monologue of the theatre play. / / /// // // ////// / /// // //// /// //// // /// //// // /. 11 december 2020,jj il pensatore.

Recording of parakeets being loud in springfield park in easy london at 7:30am in november. This was an unintentional recording as i was testing out some new gear, this meant that i wasn't able to unclip the mics from my rucksack straps and avoid picking up the rustle of my clothes and some breathing. A train and canal boat engines can be heard in the background. This recording was made using a sound devices mixpre6ii and a stereo pair of fel em172 mics.

We develop iphone app that perform musical analysis on recorded audio from the iphone. Our app implementation make use of the audio queue service to receive raw audio buffers from the audio queue callback. In the first version of our app we had the problem of too much clipping on the recording which degrade the accuracy of our analysis. We also suspected that the noise canceling algorithm in iphone 5 produce distorted sound, which is not much noticeable by human ear but distorted enough to affect our sensitive algorithm. We found that the solution to our problem is to set the audio session mode to kaudiosessionmode_measurement. This session mode is supposed to give maximum freedom for us to control the microphone input, which include turning off the automatic gain control and probably noise canceling as well. The solution works very well except that it introduce a strange waveform pattern in the beginning of all recordings in iphone 5. It is very hard to explain the waveform we get, so i made two recordings at freesound so that you can see it visually. The first recording is made in an almost quite environment, and you can see the weird spike in the beginning of the recording. The second recording (this recording) is made with constant background noise, and you can see that the actual sound wave is offset from the strange curve and gradually increase to its original volume. This waveform only happens on iphone 5 devices that we tested, and there is no problem at all for iphone 4s and older generations. We have tried various settings and the glitch is still unavoidable as long as we set the audio session mode to kaudiosessionmode_measurement. We also find similar glitch in one of our iphone 5 devices, in which the glitch happens even if we try to set just the input gain level without changing the session mode. We are not sure if this is a hardware-related bug in iphone 5, or if it is fixable software glitch in the future version of ios. For the moment we are looking for workaround that can avoid this glitch while automatic gain control and noise canceling are disabled.
