Would you like to convert this DSD Project into a DXD Mixing Project ?
If the answer is YES the project will be opened in DXD Mixing mode . (Though all your media files will remain in DSD
IFF format)
If the answer is NO the project will be opened in DSD mode as it was when created.
Peak Values in DSD and DSDIFF Media Files
Peak Computations
For DXD audio media, the peak displayed in the media Properties page is computed from the audio without a
[20..20kHz] filter.
For DSD audio media (DSDIFF), the peak displayed in the media Properties page is computed from the audio after a
[20..20kHz] filter.
This could change the behavior of Auto-scale Waveform and Normalize .
For example:
A DXD file generated from a 1kHz sine @-10dB -> peak = -10dB
A DSDIFF file generated from a 1kHz sine @-10dB -> peak = -9.9dB
