The Noise Audio Recorders Won't Like

Audio jammers are popular tools used during confidential meetings. They produce a unique sound for masking and protecting conversations from external listening devices, such as a smartphone running an audio recording app, hidden in one of your guests' pocket.

The sound of a jammer should be very difficult to filter out or remove when present in an audio recording. While commercial audio jammers often rely on white noise, this generator, however, uses a more efficient sound with articulation similar to speech. It is also buried under severe distortion, which makes recovery algorithms have a hard time producing exploitable results.

For further privacy, increase the generator's volume to play louder than your voice. Then, if you are holding a conversation in person, speak quietly, and very close to your partner so they hear you over the sound.

  Colleagues plus annyoing christmas carols on the radio - blocked!

  This really helped me with doing homework. Completely blocked out my neighbors! SO GOOD!

  I use this speech blocker every week when the person I live with has a confidential meeting in the next room. Works great, I can never be sure they're even speaking at all!

  I have people I live with listening to all my conversation and pretty much anything I do upstairs... Why they feel the need to do what they are doing is still yet unexplainable... This app helps tremendously when I need some privacy...

  I can get HOURS of work done in my house FINALLY because of this incredible noise-blocker. THANK YOU !!!

  My go to tinnitus mask. Noise to some. Heaven to kill the horrific ringing. Thank you so much to everyone.

  A great help! I live in a prefab with neighbours using strong acoustic equipment, penetrating the walls, floors and ceilings; they're also using listening devices. The strong acoustic emissions, in my opinion, belong to industrial equipment rather than domestic. My home has structural problems but landlord won't fix it. Super-quick solution for their listening devices! Ta, very much!

  This sounds a lot like certain audio hallucinations I get. So, yeah, bad memories. BUT. I'm very certain that this will be able to block out noise wayyy better. So... thanks but no thanks?

  My spouse talks like Brian Blessed on the phone and this noisemachine set to 'animate' is the only thing I've found that can block him out. Probably saved my sanity over lockdown when we had to share an office.

  These noises plus some relatively cheap earbuds managed to completely knock out of the speech of a television I was less than 10 feet from. I am floored, this is amazing.

  This is my favorite noise blocker. It completely cuts out the conversation, music and other extraneous sounds. I didn't think I would like it initially, but using it is a relief and I can easily relegate it to background. I enjoy it greatly.

  You would think libraries would be quiet. This completely drowned out the loud college students next me, another college student just trying to write lab reports. It's perfect for blocking out erratic conversations or the general noise of busy library entryway.

  The dead sheet hacker currently infested in my phone for the last 6 months listening 24/7 to my microphone loves this sound and so in turn I love it even more.

  First all I would like say, that this generator and this whole site is ablsolutely NUTS! Thanks for that! I am listeting to this with these setings, whitch are made in a way that the sliders are in a effective level but I don't hallucinate any voices in it at the same time. Playing it together with Cafe Restaurant, to boost my creativity... NUTS!. ..and.. DOPE! ... ehm.

  It works well but it sounds too much like the audio hallucinations I got during sleep paralysis...

  Kill your ears.

  Works good but the sound is harsh.

  This generator is nuts, it completely knocks out human speech from television shows so I can zone out and not have to worry about someone watching the TV and distracting me.

  This mixed with Flying Fortress is the perfect blend to mask the loud conversations of my colleagues and aid my concentration.

  This works great for me for blocking out conversations. I was working on a project at a cafe where there were a lot of other people playing board games, and this blocked them all out for me!

  I work in an assisted living setting and I love it! But when the documentation has to been done in spite of blaring news on the television, emoting and clanking from dinning room and perturbed family members roaming the hall. This is a fundamental tool to getting proper and patient focused data down and done, for me. Thanks!!!

  I work next to someone very loud. Their phone conversations, all day long, are a constant distraction to me. This particular sound scheme coupled with noise-cancelling headphones is absolutely wonderful!

  I don't like the sound of this when it's by itself - it makes me feel tense, not productive. But with low levels, and Circular Breeze open in another tab, it turns into a pretty whispering wind/water background noise. This is effective for blocking out a noisy open-plan office, while also making me feel peaceful and productive.

  Just try to sleep after listening to this for an hour! haha :P

  This generator actually saved my day. I was sitting in the co-working space, but this day there were a loud group of people... This generator helped me to mask all their noises and keep working. It was perfect: I didn't need to make the sound loud, but from time to time I was turning a head to check if those people are still here - because I didn't hear any sign of their presence. :)

  Very strange at first, but I'm now lost inside the sound, distraction-free and the noise from other apartments neighboring mine minimized. I really enjoy it.

  This one is awesome for shutting out the sound of someone watching TV in the room I'm in, when brown noise alone isn't enough.

  Next to the internet cafe where I am now is an ongoing renovation, so we have the lovely sound of construction equipment as our background music. This noise surprisingly blocked the construction noise without being too distracting!

  ← Complete distortion

  I'm in an internet cafe, writing my thesis while the other people in the internet cafe are playing games and cursing loudly. Of all the generators I've tried, I found this noise the most effective in blocking the noise of other people.

  At its default settings and lowish volume, it's very good for completely blocking out nearby conversations when I have to get some focused writing done in a short period of time. It's not something I can listen to for long periods, but for an hour or two, it's unreasonably effective.

  Nightmareish

  Love this. Truly fascinating sound - I work in a small call center performing database maintenance. The phone calls on the other side of the room can get quite distracting. I've used myNoise quite frequently with amazing results but Audio Jammer is the first one to inspire me to leave a comment. Total block-out. 10x focus!

  I turned it up a little bit from its default, then animated at maximum speed. The result sounds like calm and routine radio traffic: police, fire, EMS, security, military, corrections. A wonderful sensation, perhaps topped only by the soothing beeps and chimes of hospital emergency department equipment on an overnight shift.

  No matter what I do, I can never completely block out any type of noise. This is AMAZING because it is the first thing I have ever seen that will almost completely block out all voices. Great for working, thank you!

  I'm waiting for the day when someone asks me what I'm listening to.

  It might be a weird use for it, but putting this generator on animate, and using the Dungeon RPG sliders 1, 2, 6 and 10 creates a sort of sewer noise that is strangely relaxing.

  It's so cool. It reminds me of AI Handsome Jack's voice when it becomes distorted in Tales from the Borderlands :D

  Thank you so very much for taking the time to create such a useful tool for speech protection! I fully understand why this is hard to remove on a recording! This will come very handy mixing it with other speech protection devices! You did a amazing job! You truly care about your my-noise users! Thanks for everything! And keep up the good work!

  Though jarring at first, I'm discovering that this is a very calming noise mask for the office! The speech-like sounds replicate vague human energy so I don't feel isolated, and the white noise aspect keeps it firmly in the background of consciousness. I have it animated along with Telecaster Licks and am enjoying very focused attention. Another fascinating sound, Dr. Pigeon! Many thanks!

  These particular bands sound very much like speech that is doused in distortion. As someone who is deals with audio on a regular basis as my job, I see exactly why this works so well. In addition, as someone who values privacy I think I will be putting this to good use. Many thanks for your work, and this knowledge/experience.

  Very annoying, but a great noise blocker!
