This is the audible annunciation found at all intersections with traffic lights in paris, france. It announces the condition of the traffic lights for pedestrians who are blind or with impaired vision. The annunciation is turned on by pressing a button on the traffic light pole. When the crosswalk sign is red (do not cross), the recorded annunciation is always "rouge piéton" ("red light, pedestrian"), followed by the name of the street that the crosswalk crosses (in this case "rue d'antin," the quiet side street where i recorded this). This repeats over and over until the crosswalk changes to green, at which point there is a two-second trill tone followed by a repeating bell tone. The bell tone is one bell, followed by two bells, repeated four times, followed by a very brief pause, and then the sequence is repeated again. This continues until the crosswalk changes back to red, at which point the "rouge piéton" message resumes. The annunciation continues for at least one cycle of the traffic lights and then stops, unless the button is pressed again. The audio quality of the annunciation is very poor even in real life (it sounds like a wax cylinder recording or something), and can be difficult to understand. This recording accurately captures the poor quality of the annunciation. The volume of the annunciation is also adjusted dynamically based on ambient noise, so there is a slight change in volume on this recording as the system apparently reacts to noise from traffic or something. There is a weak background noise that sounds like some sort of machine, but it wasn't coming from the traffic light and i don't know the source. The recording starts with the crosswalk red, then at about 18. 3 seconds it changes to green, then it changes back to red at about 53 seconds. A car passes at around 48 seconds. Recorded with a zoom h4n, stereo 96 khz / 24 bits, built-in mics, from about ten inches below the tiny speaker in the crosswalk sign housing.

While working on another audiobook, i decided to make this sound. It's 38 voices, each saying different things, panned around and mixed together, creating a "wall of sound" that speaks like 38 radio channels at once. Recorded with a zoom h2 via usb into ardour2. Mixed and exported to flac with ardour2. Ps: it's all polish (with some possible german shout-outs), but the amount of noise makes it almost completely incomprehensible. Only a few words that are being yelled in a different voice can be understood. No sound repeats here, no recycling - every voice and every second of this recording is unique. Yes, it required quite a lot of work to record so much talking in quality! it's almost an entire audiobook squeezed into 5 minutes. Strangely (or not) listening to this makes my mind rest, because the noise blocks all other sounds from the environment - making my mind free of stimulation, allowing for sleep-like rest state. The signal is so much modulated that it appears to be not modulated at all - like static you get from a fm radio of you tune it wrong. The brain receives less data when you listen to this, than when you sit in a room hearing even faint (but distinct) noises from outside, other rooms, other people or yourself. This is sound masking in action. A very interesting psychoacoustic property of human hearing. Also: this is an interesting material to study of my voice's spectral energy distribution while speaking (as opposed to singing). As you can see using the spectrogram view, most energy is present in the band below 600 hz.

Trying to start a 1983 volvo 245 after a stop at a gas station. First we hear the seatbelt warning signal after the driver turns the ignition on. The first start attempt fails. The two following attempts fail because the starter fails to engage with the flywheel, creating a very loud and unpleasant sound. There is some reverberation from the metal roof of the gas station. At 00:24, the driver remarks "he's doing it again!". The fourth attempt succeeds in starting the engine after a rather long cranking. We then drive off and we also hear some squeaking from the steering wheel. Throughout the recording we hear breathing noises from the driver (80 year old man, smoker). The recording was made in the front passanger seat with the window open, that's why there a very noticable difference between the left and right channel. Recorder: edirol r-09, 48khz wave/24-bit, cropped with cool edit pro, re-saved as 48khz wave/24-bit and compressed with flac. No other pp. Edirol r-09 settings: low cut: off, mic gain: low, agc: off. Recorded on june 15, 2012 in åkersberga, sweden.

Created by divkid for use in the make noise soundhack morphagene. There are dry-only, fx-only, and mix versions of this reel in the pack. See it in action at https://youtu. Be/rk4ufmfcouc. Patch walkthrough. The patch starts with the qu-bit chance providing discrete random values (sample and hold) going into an instruo harmonaig. This takes the stepped random voltages and quantizing them to a given scale. I put in the notes c d eb f g ab bb which is a c natural minor scale, the relative minor of eb major (for anyone that's curious). However like most of my modular work i didn't actually tune the oscillators to anything specific. So treat the scale as a pattern of intervals not a set of specific notes. The quantized notes then form 4 voice chords giving us a root, third, fifth and seventh cv output that will be diatonic following the scale pattern, meaning the third will be major or minor, the seventh major, minor or dominant and the fifth natural or diminshed to suit the scale. With the 4 quantized outputs on the harmonaig these all go into the four oscillators on the synthesis technology e370 quad morphing vco. Each of the e370 oscillators are in the basic morph xy mode using the built in rom b set of wavetables. Wavetables are modulating by various mixes of the befaco rampage, mutable instruments tides, wmd multimode envelopes and music thing modular turing machine. The modulation sources are mixed and split with multiples and mixers. These modulating wavetables then go into a bubblesound vca4p where i'm using 4 mk1 intellijel dixie oscillators all un-synced and free running with sine wave lfos. Each lfo freely fades the voice in and out of the vca4p. As this is unsynced there's no regard to pitch changes linked to changes in amplitude and the swells. I find splitting the gate/rhythm from pitch regarding sequencing to be a freeing and interesting way to work that's not available on traditional instruments. This is just a simple application of that idea with the lfos fading freely unrelated to the other modulation or sequencing of pitch. The sound then goes from the vca4p mix out into a befaco mixer and praxis snake charmer which the output section of the larger case and i'm sending a 'pre' auxiliary out into my fx case. The dry sound first goes into the erica synths fusion delay / flanger vintage ensemble which is giving me short modulated delays giving vibrato like sounds and pushing the input level and overdrive gives us some warmth and grit that thickens up the sound and also fills in the gaps left by the free running lfos pulling quieter sounds and compressing in the on board tube. This then outputs to the feedback 1 bit multitap delay module which has it's delay chip pushed to longer times for some added crackle and noise. I'm using the two delay taps for a shorter and longer delay with little feedback to mix the dry sound for a generally noisier and smeared version of the input. This then goes into the xaoc devices kamieniec with it's on board lfo as slow as possibly for a mildly resonant phase shifting. This goes into mutable instruments clouds set to sew random grains slowly and randomly which are pitch shifted up 2 octaves to fill out some high end flourishes against the closed chord voicings at the core of the patch. Finally this goes into a long lush reverb from the halls of valhalla card in the tiptop audio z-dsp. The stereo fx chain and the mono dry signal are mixed in the befaco hexmix and recorded as a mixed stereo file. I'd consider this to be the main 'reel'. However i split the dry signal and the fx only wet stereo signal and recorded those at the same time so you can choose which reel to use and experiment with dry/wet or blended sounds from this patch.

These are fake siren noises i made in logic by using es p. The warnings are in the following order: caution (three pulses), alert (steady), attack (wailing), large fire (hi-lo), evacuate (hi-lo/alternate wail). These don't conform to any signal guidelines and must not be used for anything other than a mere sound effect.

An artistic experiment searching for sound emissions and the limit of human hearing. Composed of infrasonic material that have a low acoustic impedance. Humans will be able to identify tones as low as 12hz. Natural and human produced infrasonic sounds is anywhere, all the time. The artistic idea was to use background noises, signal fidelity, harmonic distortion, low-frequency in order to foster a soundscape of infrasound that travels through space. Made for project that was never released. Think somebody might enjoy or use it.
