General Audio / Re: Undecoded Dolby A: Why People Complain That Digital Sounds Harsh
Last post by board -
As far as I know blind tests have already been conducted between DSD and PCM and people couldn't hear a difference, despite the fact that DSD seems to be a broken format according to a paper published by Stanley Lipshitz and James Vanderkooy, which just shows us how forgiving our ears really are.
The faults are typically about 100dB below the music, so never audible. It was more an objection on principle.
Yes, exactly. I don't get positively excited when I see DSD printed somewhere, since I know any difference in format isn't audible. About that paper, though, the +20 kHz errors were many.

Thanks. I seem to remember now seeing him mention it once. It even seemed like it was the same type of cancer that took my father away :-(.

General Audio / Re: Spotify has new low-data mode

It's HE-AACv2 24 kbps

https://support.spotify.com/us/using_spotify/system_settings/high-quality-streaming/

"Low - Equivalent to approximately 24 kbit/s (HE-AACv2 format).
Normal – Equivalent to approximately 96kbit/s (Ogg Vorbis format).
High – Equivalent to approximately 160kbit/s (Ogg Vorbis format).
Very high – Equivalent to approximately 320kbit/s (Ogg Vorbis format).
Automatic – Dependent on your network connection. "

24 kbps is too low in my opinion. But I imagine it's the way to go on 2G/3G networks.
~36-48 kbps will be considerably better.  Parametric stereo is quite bad in headphones.

General Audio / Spotify has new low-data mode (HE-AACv2 24 kbps)

  Spotify has new low-data mode for slow 2G/3G networks.

I suspect it's HE-AACv2 with its typical artifacts of SBR+Parametric Stereo. Or maybe it's xHE-AAC at very low bitrate. Quality is ok if You have bad connection.

Can someone confirm?
