Frequency-shaped background noise generators
- hobs 13y agoInteresting idea and cool presentation, I like the sliders and that I can play around with it. I will probably use this at work. edit: This is really good, I just accidentally left it on and had completely forgotten I was listening to the same thing. Very much works as advertised.
- filereaper 13y agoI really like this. I use simplynoise's noise generators to drown out noise at work (oscillating brown noise usually) But I like having an equalizer. I've opened up multiple tabs and superimposed the noises, it downs everything out. Hope you can spare the traffic.
- rcthompson 13y agoDoes it actually generate the sound server-side and send it over the network, or does it generate it client-side? (i.e. does it actually use much bandwidth?)
- lost-theory 13y agoIt loads 20 or so ogg audio files like this: http://mynoise.net/Data/OSMOSIS/7a.ogg http://mynoise.net/Data/OSMOSIS/7a.ogg Then I'm guessing the EQ controls the volume. So no it doesn't generate / stream anything to you server-side.
- theatraine 13y agoRight, the EQ controls the volume of each of the 10 (each one corresponds to a slider) sounds. (Every sound has been previously decomposed into its frequency components.) The Web Audio API is used for browsers that have it present, else HTML5 audio elements are used. The slider just adjusts the volume of the sound (exponentially of course!), leading to an equalizer effect with no filtering required. (Garnered from looking at the code.) Interestingly, this could be done using one file (rather than ten) using a Web Audio API filter node. This would limit the site to only Web Audio API compatible browsers. Unfortunately, at this time, that's only newer versions of Chrome, Safari, and I believe FF nightly (slight API variations). However there is some mobile support through recent Chrome and Safari implementations.
- audiosampling 13y agoAlmost exact... but one audio file + EQ won't be able to achieve the same result ... Have a listen to the Wind noise and you'll understand why.
- kaoD 13y agoYou could filter it yourself with a bit of DSP knowledge. I've seen this approach working effectively in Firefox without Web Audio API. Impulse filters are easy to implement, e.g. an averaging low pass filter (or at least I think so, I'm no DSP expert): out(t) = 1/sum(a) * (a_1 * in(t) + a_2 * in(t-1) + ... + a_n * in(t-n+1)) Where "a" is a vector of constant coefficents. You could even use FFT to modulate the bands separately, e.g.: Sample -> FFT -> Filtering -> FFTi -> Output
- theatraine 13y agoSure, you could pre-calculate your filter coefficients and use a bandpass for each frequency band then do the math in Javascript however it's slower, and more involved. Also, unless you're going to be using WAVs, there's going to be some overhead for the decoding of the sound. Also, the filter won't be very high order since you're going to be doing at least n*44100 operations per second (at the standard sampling rate). (Web Audio API filter nodes are only 2nd order but you can cascade them.) Do you have examples of the above working in Firefox? I'd be curious to see the implementation.
- gabemart 13y ago>I've opened up multiple tabs and superimposed the noises, it downs everything out. Hope you can spare the traffic. I built a noise generator around the concept of superimposing noises over each other [1]. I've consistently struggled with performance - at the moment it takes far too long to load properly. I'm planning to implement just-in-time loading when I get some free time [1] http://asoftmurmur.com http://asoftmurmur.com
- hcarvalhoalves 13y agoOh this is beautiful. Those textures are better than music at times. Loved playing around with the ocean waves [1], I was able to get close to the sound that used to make me fall asleep as a kid.

- rsync 13y agoAny chance you can make this a sonos-accessible station ?
- technojunkie 13y agoOh, this is wonderful! I love Simplynoise but this is even more fun. I hope they can decrease load times and make this a webapp rather than taking 2 steps to load the various noises.
- hawkharris 13y agoThis is a very useful, well designed app. I think I'll use it to help myself go to sleep and stop procrastinating with HN. :)
- defen 13y agoWow, really cool app. It really reminded me of how much I miss the sound of rain and wind.
- crazygringo 13y agoFirst of all -- awesome concept and execution, and great sound samples. Well-done. > Mobile Safari iOS 6 on iPad 2+, iPhone 4GS+ But... not working on my 4S/iOS6. :( Anyone got it working to play in the background, even when your phone's screen is off? I also wonder about battery life as HTML5 audio, vs if it were an app. The creators clearly want to support HTML-only, according to the FAQ, but this calls for an app if anything ever did -- you want it to run, providing sound in the background, while you do other stuff (whether on or off your phone).
- gren 13y agoVery interesting Web Audio API experiment, To reply to you, forgetting that the interface is not really touch friendly, I was totally able to make it run in the background on a Nexus 4 with Chrome (the Web Audio API works in the background with Chrome), however I got some clicks (interruptions) in the sound probably due to the bad performance the Web Audio API gets in Android Chrome today. I wish there was a way to contribute (Github?) to improve this app.
- robmcm 13y agoI have been using an iPhone app called Ambiance for a long time, it even allows you to record your own sounds, works in the background, has a sleep and alarm modes etc. The only down side is it tries to do too much, they have like a sound store and stuff, which is a cool feature but affects the simplicity. http://ambianceapp.com/ http://ambianceapp.com/
- gabemart 13y agoI don't really understand how it runs on iOS devices at all - to the best of my knowledge, it simply isn't possible to control device audio volume from javascript on iOS [1]. Or at least, that seemed to be the consensus last time I attempted to. [1] https://developer.apple.com/library/safari/documentation/AudioVideo/Conceptual/Using_HTML5_Audio_Video/Device-SpecificConsiderations/Device-SpecificConsiderations.html https://developer.apple.com/library/safari/documentation/Aud... - "On iOS devices, the audio level is always under the user’s physical control. The volume property is not settable in JavaScript."

- shmerl 13y agoGreat idea and implementation.
- sparkman55 13y agoThese types of sounds are absolutely wonderful for soothing angry babies!
- p1mrx 13y agoI wrote an Android app based on a similar concept, although it uses a PRNG and Fourier transform, with no recorded samples: https://chromadoze.googlecode.com/ https://chromadoze.googlecode.com/
- backprojection 13y agoSomeone posted ambient warp-core sound from Star Trek on Reddit earlier today, maybe you could add this. http://www.reddit.com/r/startrek/comments/1nwzd6/ambient_warpcore_enginesound_great_for_when_youre/ http://www.reddit.com/r/startrek/comments/1nwzd6/ambient_war...
- sspiff 13y agoAn old Linux command line trick to generate the engine sound: > play -n -c1 synth whitenoise band -n 100 20 band -n 50 20 gain +25 fade h 1 864000 1 I used this as a background noise muting sound when I was a kid.
- backprojection 13y agoThis is great, thanks!
- shmerl 13y agoHere is a softer variant: play -c2 -n synth whitenoise band -n 100 24 band -n 300 100 gain +20
- outworlder 13y agoThis is the warp core idling. I'm trying to add a slow warp to it, and after some experiment I got something. That's the first time I've used sox to generate audio, didn't even know it could. I'll play with it some more. play -c2 -n synth whitenoise band -n 100 24 band -n 300 100 gain +20 phaser 0.5 0.3 2 0.8 0.5 -t
- shmerl 13y agoSox can be pretty handy. For example it's easy to use it for musical instruments tuning (instead of buying some expensive electrical device). For example for mandolin layout: 4 (G): while true; do play -n synth pluck G3 fade 0 3 vol 0.4; sleep 1; done 3 (D): while true; do play -n synth pluck D4 fade 0 3 vol 0.4; sleep 1; done 2 (A): while true; do play -n synth pluck A4 fade 0 3 vol 0.4; sleep 1; done 1 (E): while true; do play -n synth pluck E5 fade 0 3 vol 0.4; sleep 1; done
- FYI 13y agoYeah, very cool. Saves people money as well (up to $200): http://www.sharperimage.com/si/view/product/Sound-Soother-White-Noise-Machine/201102 http://www.sharperimage.com/si/view/product/Sound-Soother-Wh... You could stream example outputs 24/7 as net radio channels so they are also available on other devices / STBs (Roku) / Consoles / Smart TVs etc..
- matude 13y agoHeh, thought it was CSS-based website background noise texture generator…
- glassdoor 13y agoIt is working for a highly Hackernews Distracted person, except I have to write this comment!
- groundCode 13y agoGreat resource thanks! I love the Tibetan chanting. Would love something that subtley changes the sliders over time.
- audiosampling 13y agoHey, this is what the "Motion" buttons does, although the slider do not move in a visible way.
- ikurei 13y agoThat's an amazin feature! I didn't notice it at first either. May be its explanation could be more visible, or it could be made more obvious...
- groundCode 13y agoThanks - did not notice that! awesome!
- kaoD 13y agoIMHO the slider should move, both to provide visual feedback and to make the effect less subtle.
- gadders 13y agoNeeds Birdsong: http://www.bbc.co.uk/news/magazine-22298779 http://www.bbc.co.uk/news/magazine-22298779 Everything feels better when listening to the Dawn Chorus.
- audiosampling 13y agoThere is something like this currently under development. There is a problem though: my noise generators are supposedly active across the whole hearing range, from 20Hz to 20kHz. And birds are only producing frequencies above 1000Hz. So, I need to fill up the bottom sliders with other sounds, or find... really big birds! ;-)
- rpwverheij 13y agoperhaps a combination of birds and ocean waves, or frogs, or yes, big birds :) ... It'll be a little puzzle, but +1 for more nature sounds! .. and perhaps one of my favourites: tibetan gongs!
- audiosampling 13y agoYour favourite here : http://mynoise.net/NoiseMachines/windchimesGenerator.php http://mynoise.net/NoiseMachines/windchimesGenerator.php
- slavak 13y agoPterodactyl song? :) (And yes, I know Pterodactyls aren't actually birds.)
- r0muald 13y agoBirds are reptiles though.
- troels 13y agoBird sounds played at slow speed sounds incredible. Couldn't you just layer the natural bird sounds with some down-shifted ones?
- deleted 13y ago[deleted]
- NatW 13y agoNice!! A request: Can you add Pink Noise?: http://en.wikipedia.org/wiki/Pink_noise http://en.wikipedia.org/wiki/Pink_noise One (of various youtube examples) here: http://www.youtube.com/watch?v=ZXtimhT-ff4 http://www.youtube.com/watch?v=ZXtimhT-ff4
- lhaussknecht 13y agoGo to White Noise and pick Pink Noise as a preset.
- audiosampling 13y agoPink noise can be found under White Noise (because all myNoise noise generators are spectrally-tunable, there is no reason to have different color noise generators: the white noise generator can be shaped to any imaginable color, and a pink noise preset is already provided for you).
- dhimes 13y agoThis is really great. I listen to sounds like this alot as I find they help me focus. I've used environmental recordings of rain, storms, and ocean waves for years (decades, actually) and I usually loop them in Banshee while I work. I've seen a few of these noise generators in the past but never really came back to them because they weren't superior to my recordings. Your generator, however, is exceptional. One request: when we make a selection, say a preset, would it be possible to have an indicator that shows what we had set? I find myself selecting something, then working a while, then coming back and being a bit forgetful!
- audiosampling 13y agoYour request has been implemented...
- ewoodrich 13y agoFantastic. I tend to not like rain sound simulators, but the sliders let me pick one that seemed believable and familiar. I loved how the darker end of the spectrum let me simulate a visit to the Oregon coast. (After which, I wished there was actually a storm right now, until I walked out onto my balcony and realized it was raining.) "Too much internet for me" as they say.
- audiosampling 13y agoHi Guys! I am the developer of the myNoise website and just want to say that all your comments are a great source of inspiration today: many suggestions for further improvements will be taken into account! Although I did entirely code the website by my own using a simple text editor, I am not a programmer, in the sense that I never learned how to program efficiently and beautifully. Multiplatform issues, and mobile browsers in particular, are driving me crazy ;-) And yes... I feel a bit "naked" now as some of you are digging into my website code with much expertise. Please be indulgent! ;-) Cheers, Stephane
- calibwam 13y agoThanks for doing this, I'm going to use this page a lot, I think. But have you thought about open sourcing some, if not all of the code? With the source code out on for instance github, a lot of people could help you out wherever you feel your own skills come to short.
- audiosampling 13y agoLet me think about it... Not sure about all the implications of releasing this as open source, in particular the investment in... time. I wish I had 48 hours in a day.
- kintamanimatt 13y agoIf it were me, I'd not open source this. Common tools that are used to build other things generally are, such as a compiler or VCS, but an actual finished product, not so much. Open sourcing this would be like Github open sourcing github.com, rather than just a handful of common tools they built to create github that might be useful to others. Open source has a time and a place, but some things, like finished websites, are best left proprietary. There's a lot of thinking that's gone into this site. I think the #1 thing that would happen as a result of open sourcing it is that other people would just take the her work and creating clones, eroding her ability to make money from it (if she so chooses). Choosing to open source something should be done only with a compelling rationale, and the downsides should always be carefully considered.
- rpwverheij 13y agowow, thank you! I think I'll be visiting this site often when in need for precise brain tuning support
- JonnieCache 13y agoAlso fun: loads of real field recordings on http://freesound.org http://freesound.org Use the geotag browser and listen to the wilderness of your choice! http://freesound.org/browse/geotags/ http://freesound.org/browse/geotags/
- JonnieCache 13y agoJust realised: these are all under various CC licenses, so OP you could easily integrate them into mynoise.net
- shmerl 13y agoGreat find! You can make a good sleep mix from those :)
- newsmaster 13y agoDon't know why but I find the babble noise really creepy. http://mynoise.net/NoiseMachines/babbleNoiseGenerator.php http://mynoise.net/NoiseMachines/babbleNoiseGenerator.php
- ewoodrich 13y agoWow, I agree. At least for me, the fact that I can't pick out any real words/phrases makes what could be believable background/nice sound feel like it could be from a horror movie.
- obitoo 13y agoIt is rather spooky at first, but once I got over that its excellent for blocking background office noise. Now what would amuse me NO END would be if once, (and just once) after a few hours, it was coded to fade out and play a distinct voice along the lines of "You're going to die today". I'd love to do that to someone!
- grn 13y agoI use http://simplynoise.com http://simplynoise.com to put my daughter to sleep. It's much easier when the noise is playing. I also use http://rainymood.com http://rainymood.com to isolate myself from the environment when I'm working.
- tinyzor 13y agoThank you (I have tinnitus).
- Shtirlic 13y agoTonal Drones are great, iPad application needed.
- kintamanimatt 13y agoOne strange thing I noticed about this is with the cabin sound, listening to it for a prolonged period tends to cause ringing in my ears like I've been listening to loud music, except I'm listening to this at low volumes. This isn't something I've experienced for low-volume stuff before.
- audiosampling 13y agoFirst time this is reported to me. Please check the last slider. It produces sonic content above 16 kHz. You may have pushed that slider to the max because of a possible hearing loss. Although the sound you hear is quiet, the acoustic pressure may be higher. This is the only reason I can think of...
- kintamanimatt 13y agoActually I did -- well, to about 80% max. My calibrated profile looked a little like an inverted bell curve.
- JonnieCache 13y agohttps://en.wikipedia.org/wiki/Fletcher%E2%80%93Munson_curves https://en.wikipedia.org/wiki/Fletcher%E2%80%93Munson_curves
- LeChuck 13y agoThis is great. I especially like the cabin noise. I work on ships and for the first week or so after I get home I need some background noise to help me sleep. This one sounds quite close to what one might hear on a ship.
- pond_lilly 13y agoHow pathetic we got to listen to these noises on computer.....Digital sound will never be as good as analog.
- tama 13y agoThis is really nice. Using it at work now. Thanks!
- j2kun 13y agoHow does this work mathematically? Do you take, e.g., a waterfall track and manipulate its frequency spectrum? Or is it completely synthetically generated? If it's the latter, then I'm quite impressed that I can't tell the difference.
- audiosampling 13y agoBoth. Let's call it re-synthesis ;-)
- galapago 13y agoA (humble) request: Vacuum cleaner sound.
- conflagration 13y agoThe sounds are great by themselves, but I had the most fun layering different generators by opening several tabs. I played around with the EQ and made something sounding very close to Biosphere with 4 parallel tabs. It really felt like the tracks were synchronized to fit into each other. Great work!
- samstave 13y agoHaving a single page where you can add in any filter you wanted would be awesome.
- kaoD 13y agoNice job! Being able to share custom presets would be cool.
- audiosampling 13y agoIt's possible. Just follow the link "Save Your Current Slider Settings" then the URL. I should make it more obvious though, you are right.
- kaoD 13y agoOh, nice! I'd put it closer to the sliders and make it clear you can share the saved settings. I'd also let the user edit it without clicking anywhere. Right now clicking edit resets the sliders too :(
- shmerl 13y agoInteresting, on Linux, PulseAudio shows many channels in the mixer (for ALSA plugin in Firefox), when the noise page is opened. By the way the site mentions using OGG (I guess Vorbis) playback. How does it work in crippled browsers like mobile Safari, which don't support Vorbis?
- agladlad 13y agoThis is fantastic! Love the throat singing and the ability to play with different presets. I was using the TNG engine noise on youtube before the 24-hour version was taken down, but this is my new jam.
- matrix 13y agoThis site is awesome! A feature request, if I may: on the calibration page, it would be helpful to have the ability to mute all the sliders except the one you are calibrating. Or perhaps, like slider in a color tool, have a text box with a number representing that volume that slider is set to.
- audiosampling 13y agoIt does! As soon as you move one slider, it mutes all others ;-)
- msluyter 13y agoGreat, now I have to keep another dozen Chrome tabs open... ;) Seriously, this is pretty nice. I currently have rain, fan, ocean, Indian Drone, Tibetan meditation, and Bamboo running concurrently. A way to combine sounds without opening a new tab would be be an obvious improvement. Adding a feature that randomly (very slowly) raises and lowers volume of a sound from set of subcomponents could be interesting -- it'd give the sense that the sounds are changing slowly over time and relieve some of the stasis. Edit: just noticed the babble generator. This is genius, and exactly what I need to mask background conversations.
- onurgu 13y agoThis reminds me of Aporee Maps: http://aporee.org/maps/ http://aporee.org/maps/ You can just listen to high quality sounds recorded by sound artists around the world. It feels like you are in that place. I don't know if it's only me but I recall hours of me listening to this site.
