With a growing list of use cases calling for active noise cancellation technology, selecting the right solution for your product can be a challenge. Our expert engineer delves into the different ANC options and how to determine which option is best, as well as tips, tricks and best practices for implementing ANC into products.
Curious how microphones minimize background noise while allowing your voice to come through clearly? Discover how engineers use dual- and multi-microphone arrays, along with frequency domain power analysis, to cancel out ambient noise from voice signals.
Have you ever wondered how noise-cancelling headphones work? Check out this blog post to learn more about the different types of active noise cancellation and how the technology is being integrated into products at lower price points.
Earlier this year, the National Academy of Television Arts & Sciences (NATAS) announced the recipients of the 71st Annual Technology & Engineering Emmy® Awards, with Cardinal Peak consultant Kevin Gross earning recognition for his efforts that ultimately produced the AES67 standard in 2013.
Earlier this week, I wrote about the importance of synching audio and video, something that we use in many applications. We’ve already discussed why it’s necessary, and today I want to talk about the different ways to do it, some easier than others. Adjust the Video The most common and easiest way to correct for…
AES67 is a standard for transport of high performance audio over IP networks. High performance, as AES67 defines it, is at least a 44.1 kHz sampling frequency, at least 16-bit resolution and latency less than 10 ms. AES67 is targeted to applications in professional audio: broadcast, production, live audio and commercial and residential applications. Rather…
In the first post of this three-part series, I listed four points that I hope my readers will agree with at the end of this series. The second post addressed the first two points of the four. In this post, Part Three of the series, I will demonstrate the final two points: Phase distortions generally…
In this post I will demonstrate that dramatically different time domain waveforms can lead to virtually the same audio perception, and two waveforms with identical spectrograms can sound quite different.
You may have encountered spectral analysis. The basic idea is to take a waveform, in our case an audio clip, and determine which frequency components are in it. Think of passing light through a prism and breaking it into a rainbow.
I recently came across an allegation on Amazon.com that got me thinking. The review in question is by Andrew Grobengieser, and it is critical of the Manhattan Transfer’s latest album, The Chick Corea Songbook. Grobengieser alleges: As a lifetime fan, I was unbelievably excited to hear of the release of a Chick Corea songbook. And…
