The Public Switched Telephone Network (PSTN) started with the transmission of analog speech. This worked well for decades until the areas under city streets became saturated with copper cables, one ...

People mix up the two types of audio compression all the time. Dynamic range and lossy compression are very different things. Dynamic range compression squashes soft-to-loud volume shifts. This form ...

The word ‘lossless’ sounds like it describes audio with no compression used. But lossless audio compression is a thing. Here’s a quick primer. Lossless audio formats use compression algorithms to ...

Lossless data compression of digital audio signals is useful when it is necessary to minimize the storage space or transmission bandwidth of audio data while still maintaining archival quality.

In a previous article, we discussed analog audio SNR concepts. As mentioned, the dynamic range is restricted at the top by clipping (THD ≤1 percent) and at the bottom by the thermal noise combined ...

It's hard to depict sound. Most apps show it as a wavelength, but in reality, it's a more complex mesh of multiple wavelengths that span different high and low frequencies. But the process of ...

One of the problems I have when producing screen cams is that my voice fades at the end of the day, making the tutorials I create less clear. Fortunately, this is a problem I can easily fix in Adobe ...

The bandwidth needed for VoIP transmission will depend on a few factors: the compression technology, packet overhead, network protocol used and whether silence suppression is used. This tip ...

Voice aficionados from wireless vendors Symbol Technologies and SpectraLink agree that configuring wireless LANs for converged voice and data is a delicate balancing act. The task requires adjusting ...

Some projects seem too good to be true until you dig into it and find the secret magic that makes it all work. Take Paper Tunes by [Makestreame], a project which purports to store a song on a single ...
