Re: Where's the detail?
@MrAnalog--I am asking Cirrus to address your interest in CS43130 architecture. Unfortunately, I cannot change the policy of a supplier. You may have to request a datasheet as they suggest, but I have contacted Cirrus and asked them to address your interest.

But I am sure that if you directly contact them as an interested designer that they would help you.

Where's the detail?
Steve, where's the detail on the CS43130?  "512 single-cell DACs" sounds like an interesting approach but there's no clue about how it actually works.

I tried finding some information on the web but what I found was that "512 single-cell DACs" is simply a bit of investor bait.  Cirrus has a product page but it has no detail either.  The datasheet is "available by request".

Steve, with your position in the industy you should be able to get some real news on this part.

Such a crazy scheme, you just want to collect something or do something.

"The impedance of the headphones is automatically detected upon plug in, the correct voltage level is then automatically set to ensure safe and correct levels for the headphones being used."

 

That's a dman good thing !

 

Nice post BTW

Lossless/lossy
Steve, thanks for this new post, it is very interesting.

Not so far away in time, the most important measure taken into account when delivering multimedia content, images, video or audio, to a human end-point listener was how this content was perceived, the quality in terms of perception. That still applies to voice transmission over telephone "lines" and video content broadcasting in digital television.

For that and other reasons MP3 and other compression formats have been so sucessful, but at the cost of lossing data.

"Similar to MP3, Free Lossless Audio Codec (FLAC) is virtually lossless", FLAC is similar to MP3 as it serves for compressing audio, they also work as audio data containers, but the 100% reproduction fidelity (input and output streams are bit-to-bit identical) which is achievable by FLAC can not be obtained from MP3.

MP3HD, from Technicolor, on the contrary, does allow to obtain a lossless compression-decompression process while maintaining compatibility with MP3. But this second feature is, to my opinion, a fake. This format simply incorporates two data streams in the same file, one stream is compressed using the standard MP3 format and the other using the lossless format.

Former colleagues from the CEETI, where I was a researcher at the UCLV, were working on high compression ratio encoders/decoders for EEG, audio and EEG signals. They were able to abtain 1/40 compression ratio using vectorial quantization combined with several bit encoding techniques. Of course it was lossy, but at first it was destined to be stored for later observations by humans.
