Let's open another can of worms — are music streaming services providing genuinely lossless audio?

won't it be possible to determine if a FLAC album that you ripped yourself is identical to the streamed version, using something like paralell waveform analysis?

 

That said, I think we should set up a '100% genuine lossless file'certification system, for a fee per album and a general subscription fee per annum per provider once the initial audit is completed ;-)

 

It may not be that but hopefully, it won't be like Radio, where compression is/was used extensively to make it 'sound better' than another radio station.

compression on lossless streaming? I'd be interested to hear how that would work and end up being lossy?

I mean Radio sound quality is usually screwed up, DAB is already better but I fear it's banged up before being broadcast digitally...but FLAC files from a serious content provider like f.e. Qobuz, if those are messed up I'm done with them.

 

Albums being available in multiple formats make me weary, as it;s easy to reformat a dataset, especially with older stuff, yet newer recordings can be mastered using DXD to various formats.

 

I trust the industry as far as I can throw it. I am not that strong.... 

 

If you get my meaning.

I dunno, they could but that should not change anything beyond the CRC checksum or similar ...the waveforms should be identical. How IS DRM done these days?

 

Microsoft Word - dsp_project_final.doc (columbia.edu) This is how. Actually, a great paper.

 

I hope this helps.
