ifi audio iSilencer3.0

Does your USB audio system suffer from annoying background noise?

The iSilencer3.0 is for anyone who wants a simple way to reduce distortion and enjoy clearer, noise-free tunes.

Noisebusters!

Background noise can often haunt your enjoyment of your music or movies.

At iFi, we ain’t afraid of no ghosts and came up with the iSilencer3.0 to rid your sound of these audio gremlins.

ifi audio iSilencer3.0

Plug. Play.

Simply plug the iSilencer3.0 directly into the USB port of your computer. Easy. You’ll notice you get the deeper detail in your music. Music will seem clearer, more transparent and bass will be improved.

The spooks are gone.

Double. Less trouble.

This device can be used not only at the active USB ports but also at unused USB ports too. It will reduce EMI.

Using multiple iSilencers (and therefore the inbuilt ANC circuit) will double the noise reduction each time the number of units is doubled.

Just don’t cross the streams.

Silence is golden

The iSilencer3.0 uses iFi’s improved Active Noise Cancellation+® tech to decrease noise by 100x the common noise filter. This is equivalent to 40dB. We use our REBalance® tech to get rid of clicks and distortion.

Enjoy the iSilencer3.0

This little gadget is a hassle free way to banish those frustrating and unnecessary ‘sound spooks’ that plague your music.

As the song says, Enjoy the Silence. Long live Depeche Mode.

Noisebusters!

Reference to the 1984 film Ghostbusters. Four guys, a girl and ghosts. And proton guns that would destroy the world if you crossed the streams. Watch this.

EMI (Electromagnetic Interference)

EMI is a type of interference caused by errant and unwanted electromagnetic waves that are received and amplified by an audio system. They cause some of the annoying ‘audio gremlins’ we often talk about.

Active Noise Cancellation

Active Noise Cancellation (ANC) reduces unwanted sound by the addition of a second sound wave specifically designed to cancel out the first. This basically results in no sound at all as it reaches unwanted sound even at the lowest frequencies.

Passive noise cancellation is done by means of insulating filters and works best on the middle to high frequencies. It does not work on the lower frequencies meaning that some sound can still be heard.

Common Noise Filter

The common noise filter cuts out most noise gremlins found in typical audio systems such as RFI/EMI.

REBalance® literally rebalances the signal to address the common problem of clicks caused by jitter. This is a form of digital distortion that leads to data ‘packet’ errors and cold harsh sound.

Our technology re-balances the signal to ensure that the digital signal received by the DAC is identical to the original source, no matter which audio format is being played.

Quiet! Active Noise Cancellation+® (ANC+) at work!

Exceptionally quiet power. The measured noise floor is 100x quieter than the common noise filter.

So, why USB3.0? USB3.0 allows for a greater amount of audio transfer due to the better wiring specification. It is still backwards compatible with USB2.0.

This little beast works miracles

I have a USB out into a $100 dac which channels into an old receiver and a simple 2.1 speaker setup. The system is connected with properly shielded wires. Prior to this device, plugging the USB directly into my laptop resulted in a minimal (but annoying) electrical whine from the speakers, if they were playing music or not. Connecting through my docking stations USB took the whine to 11 – it was so loud and annoying that I could not work in the office unless I fully powered down my receiver, to say nothing of the poor music quality.

Enter, this little wonder beast. Now, connecting through my dock to minimize the number of USB cables connected to my laptop the electrical distortion is completely undetectable until my ear is 2 inches from the speakers. Of course that will never happen in practical usage.

My office is nearly silent until I hit “play” and the music emerges from nowhere. It makes that much of a difference. I have personally recommended this device to friends, and will likely pick up a few extras. I cannot imagine ever plugging in a USB speaker without it.

For those who claim that “digital is digital” and this is a scam that won’t make any difference, I will remind them that electricity runs through even “digital” wires and that audio equipment translates that into feedback. But my office is so quiet it is as if the equipment is turned off until that magical moment when the music arrives.

I could easily go on, but just buy this thing. It made more of a difference than any other piece of my audio setup.

Rather useful accessory

The iSilencer manages rather well in correcting the artifacts of the usb, the audio improves in a rather light way, it is said that you can not perceive the improvement. The product works, but it is not essential, I recommend the purchase only if you have really noisy usb ports and in any case with good dacs.

It works

..I had a return hum from pc to dac .. inserted this product and I solved the 90/100 of the problem.

Effective and easy to use.

Effective in reducing the noise produced by the computer, especially when powered by power. In some cases, even the small size can prevent the use of nearby USB ports.

IMPRESSIONS: iFi’s iSilencer and DC iPurifier – more tools for less noise

“No-brainer tip of the day: if you’re using a computer or streamer with USB ports for audio, get an iSilencer.”

Excellent

This product has done an amazing job of cleaning up my electricity supply, resulting in a much more enjoyable picture and sound. Impressive.

Phenomenal!

I recently bought the isilencer 3.0 from the same brand. This brought so much to my GD NFB 29H audio that I wanted to try the more advanced version of the system from IFI.

Although I took it, it’s breathtaking! The bad news is that it’s even better using the isilencer 3.0 at the PC output and the Ipurifier 3 at the DAC input. It’s better but it’s more expensive … But the investment is really relevant. Timbres, dynamics, rhythm, harmonics, reverbs, depth, etc., we win on all fronts. Expensive but ultimately in terms of the result, it is an excellent investment.

What a awesome analog sounding upgrade!

I can’t see why there would be any negative reviews!

This little usb jitter works amazing.

Immediately I noticed my qobuz music sound more focused and the digital glare is gone.the music is so analog sounding now and have no need for vinyl anymore.
Cymbals sound brassy,the mids come out of the speakers more.the bass is full thick and tighter and warm.I can’t wait to buy another one!

IFI AUDIO ISILENCER3.0 AND THE IDEFENDER3.0 USB AUDIO PURIFIERS

There is an endless array of DACs and Amps and DAC/AMP combos, headphones/speakers and, of course, high end audio cables. High fidelity audio does come at a hefty price, especially if you’re looking for an endgame headphone setup.

If you can’t imagine spending hundreds or thousands on multiple variations of audio components, you actually don’t have to. If you already own a decent DAC, tube amplifier and audiophile quality headphones, a USB audio purifier might be all you need to improve your listening pleasure!

It worked!

I have been fighting a loud hum or buzz sound in my dash camera recordings. I had finally found that if i didnt use the cars power , then there was no buzz. I have a 12v to 5v converter and a USB from the 5V to the camera. This device plugged in between the USB cable heading to the camera.

It totally stopped all hum and buzz sounds. There is now just a crystal clear sound of my radio or someone talking! It worked perfect. Your problem my be different than mine but for me, perfect!

Does What It Says On The Tin

I had a super annoying A/C noise issue with my USB audio interface (presonus audiobox USB 96) that I knew was the PCs fault (proccessor/mouse noise) and just put up with it for a while. Then I researched and found this. This thing almost 100% killed the noise.

You have to practically put your head up to the monitors to hear it and can BARELY hear it on headphones. I love when something works as advertised. One of the only things I’ve ever rated at 5 stars.

Overview of iFi Audio accessories and filters – does filtering matter?

This article was born in my head a long time ago, mainly due to repeated questions from time to time, whether I had contact with filtering devices like iSilencer, Jitterbug etc. But since I run my humble blog, I’ve probably got used to most people to a few maxims, which I am guided in total not only in the field of audio equipment, but generally in life…

Ifi xDSD & Silencer – Treat your headphones with a piece of luxury …

“…So two years ago I bought a DAC / FiiO Andes e07K amplifier, which is able to tighten just 250 OHM headphones. After minor sound adjustments (bass + +1, +2) I was happy with the sound … Until iFi sent an xDSD amplifier to my test…”

Squished the bug

Bought and returned another well-known USB audio noise killer as it didn’t do much. The Silencer did more, a lot more. I only have a reasonably priced Schit audio dac amp but from the forums they don’t do much to clean up the USB data and power line as they have their own decrappyfier for 100 quid. Anyway the iSilencer does the business for half the price. I have read that the USB power ports are joined up so more noise is killed by more of these products. Love the Amazon speedy service of sending out the iSilencer

Positives –
i. It works better than others
ii. USB3 technology which is better than USB2 tech

Negatives –
i. 50 quid is not a steal
ii. Can’t fit two side by side easily

Best Way to enjoy SXFI headphone amp

I have tried many combinations including using two iDefender3.0 in series which lower the noise floor for better instrument separation. However, it does remove a bit of musicality. The last hiss in vocal, the engage the listener.

The last combination has the same lower noise floor without the con of removing musicality.

The combo of iDefender3.0 and iSilencer3.0 is a winning combination. Using a portable battery remove the pop sound during notebook power up cycle. You know iDefender3.0 does isolate USB power when that happens.

Works very well

My second IFI product, the first being a purifier2; this Silencer has a similar type of effect. Connected between pc and dac/headphone amp, the background is blacker and the music flows better.

Also Ive heard a lot of very quiet stuff in the music that without the silencer, I never quite caught.
Very much a worthwhile buy.

It works!

This stuff actually works. I have made recording from my UD503 to confirm this. I now have a more rounded 3D soundstage. However I haven’t tried using it with idefender yet.

Super cool gadget can be used in so many ways

Wow 49usd worth every penny for a critical listener / audiophile. For non trained ear it maybe a little difference but here are my observations :
Lowers noise floor, soundstage gets deeper (blacker) , digital glare and haze lifts, sounds get lot more neutral , clearer, less congested as all instruments spread more into their own space …. so there is more “there” there along with harmonics and air filed with more natural sounding decay. There is no more bass there or highs but bass gets more focused and better articulated , highs are cutting thru with more space and pace 🙂
Crazy little gadget.
I tried it with USB stick while plugged into cars stereo , than out of the andriod phone before signal went info 89usd hifimi Sabre DAC and Hifiman 400i , than into onkyo receiver, than Audio Alchemy DDP1 ….. results were best heard on DDP1 and than Hifime with headphones

Single biggest difference is space and ease of listening it brings.

Im a critical listener with 30 yrs of critical listening…. These are my personal observations .

Great USB filter

Makes music sound more natural and lowers harshness of digital audio by lowering jitter and emi/rfi. Works better than the Audioquest Jitterbug.

This is a great solution to the problem

I use this with my Razer Kraken 7.1 and it removes all hiss and popping noises. If you use a USB headset and have feedback issues, this is a great solution to the problem.

Excellent product

Resolved communications breaks I had previously had with my USB3.0 to DAC connection. Excellent product.

Highly recommended – not just for lowering noise

Very cool product! I expected lower noise floors on my various DACs, and it did lower the noise somewhat. But the real improvement was an increase in dynamics, more clarity, more detail (without brightness), a sense of ease, and more “bloom”. Unexpected but very welcomed! Highly recommended.

Works wonders with DC Purifiers and iPurifier 2

After trying ifi audio iPurifier 2 and DC Purifiers with success, I was inspired and decided to give iSilencer a shot. Not expecting much, I found the latter works very well with the formers but on the other end of the USB chain. Highly recommended!

Audio chain: AudioPC > iSilencer > Curious RUR link > W4S RUR (with DC Purifier plugged in) > Curious RUR link > iPurifier 2 > DAC.

5/6/2017 update: audioPC => iSiencer3.0 plugged into spare USB port; audioPC => iDefender3.0 => Curious short USB link => iPurifier2 => Nano iUSB3.0 => Curious short USB link => DAC. Music playback takes on a holographic, detailed, full body, clear presentation.

If USB audio noise bugs you, get this thing. It works

I read all the reviews, and thought a LONG time before buying this gizmo. I recently bought a very IN-expensive remote-controlled, DC-powered MP3 player that runs songs from a USB drive or SD card. It’s a convenient little device, but unfortunately, it also transmits a lot of “jitter” into the audio as it reads MP3 files from the USB drive … a common problem with USB-based audio devices, I guess, because they transmit both power and audio data across the same circuit.

Thus, I had to decide between, e.g., tossing the player; gritting my teeth and living with the noise, or investing five times what the player cost to buy this filter, in the HOPE that it would provide enough noise reduction to make it worth the investment. I’m VERY happy to report … it WAS worth it. This thing actually works. It doesn’t totally eliminate the noise, but substantially reduces it … to the point where it’s hardly noticeable through headphones, and almost completely absent through speakers.

Actually works

love the fact that the iSilencer actually works as advertised. Plugging this into either my pc or phone makes the audio coming out of my dac/amp cleaner and clearer. I also noticed an increase in sound stage and better imaging/instrument placement. The only kind of downside to the iSilencer is that it makes music slightly less dynamic. I like how the treble is tamed and becomes more coherent but the bass is also slightly subdued, although I do notice that the bass is tighter and quicker. It also eliminates the humming and clicking noises (jitter) I would hear in music.
