ifi HDMI iSILENCER Review

[@aj8ky]

Thanks m8. Another interesting video.👍 Have you already upgraded the Apple TV power supply?

[@danbretherton]

Yes I did and I must say the iFi hdmi silencer was a more noticeable improvement to atmos audio

[@MatthewCrawford]

It appears the product is a power line filter to reduce power line hissing noise at most. There should be no change in the audio as @RadiationNetwork pointed out. To test your changes, you will need to record the audio out of your HDMI receiver with and without the adapter inline. Plug an audio wire from the back of the receiver back into your PC and record both. Then you can look at the wave form to see if there is an actual difference or if the placebo effect is causing the auditorial difference. Open the device and show us the insides. Would be interesting to see what is actually in there.

Snake oil ....

With respect, why are you interested in improving video when you watch a projector. Also, is it possible that the iSilencer just has an exciter effect (eg. 5K) in it?

[@danbretherton]

I wasn’t aiming to improve video, if you watch the video the focus was improving audio

Worthless scam product! I would say you were scammed but you probably got it for free for a review. HDMI is digital, the audio is digital. Products like capitalize on misconceptions about digital signals. The way HDMI works is by transmitting a series of 1s and 0s, meaning that there is no gradual signal degradation like with analog signals. Either the signal is good enough to display perfectly, or it fails entirely, resulting in obvious errors (like screen artifacts or no picture at all). The concept of "clearing up" or "enhancing" a digital signal to reduce "noise" doesn't really apply here. If anything, adding a third-party device like this could introduce more points of failure, potentially causing signal interference, latency, or degradation if not implemented properly. Additionally, terms like "active noise cancellation" and "jitter elimination" are more relevant to analog systems and do not have much real-world impact on HDMI audio/video. In a well-functioning HDMI setup, jitter or noise isn't something users should worry about. This product preys on technologically illiterate users who don’t fully understand the differences between digital and analog signal processing.
