DSD Has Better Dynamic Rage = Misleading

I just read this post on DSD Guide about DSD and dynamic range. The post is a bit misleading, especially the sentence, "For me this analysis clearly shows that DSD has the best DR values."

 

I left the following comment (see image), that's awaiting approval to be published.

Absolutelly. It is necessary to separate dynamic range of music and dynamic range of resolution/medium.

 

Dynamic range of music is matter of record mixing/mastering.

Higher resolution of medium give more potencial (it is not guaranteed) for the wider dinamic range.

As formats, DSD has +6dB greater dynamic range than PCM.

 

I reduced it to 0.4 dB. Though in the settings possibly add headroom value:

The reason?

 

In the posible settings, are those minus, like in -6 dB ?

 

Thanks,

Hi Roch,

 

-0.4 dB used for maximal amplitude using. It was accepted by number of test files (test signals and different musical ones). This headroom provide stability for known me audio stuff (that was converted since 3-rd generation of filters was released).

 

If used wide filter band mode (Settings > General > Filter mode "non-optimized wide resampling filter"), there is higher probability of break stability due overload. Especially for DSD 64.

Though I still don't got reports about break stability issue since wide mode was released.

 

If output file contains silence or constant oscillation, need to increase attenuation.

I suppose, 1 dB must cover all cases. For more fine tuning 0.1 dB may be used Main window > Levels > Output file volume slider (if it is available in used edition/configuration).

 

If you want to convert DSF files with "standard" headroom, you can set attenuator to -6 dB.

 

Best regards,

Yuri

 

P.S. Besides amplitude limitation, other efforts for modulator-stability improving are used in AuI ConverteR.
