DSP features on new Weiss DAC

[GuillaumeB]

I thought this was interesting since it shows some of the (fun) stuff that can be done with DSP and in a way highlights how little new stuff we have had from Devialet lately (well since May 2015):

You have to scroll down to "main Features":

• Room Equalizer - to suppress room modes for a decent bass reproduction.
  

 

• Creative Equalizer - a tone control with low boost/cut, high boost/cut and mid boost/cut. Very useful to correct those recordings which do not quite sound right.
  

 

• De-Essing - the automatic removal of overly bright sibilances from human voices. The sibilance effect can be more or less pronounced depending on your speakers or room acoustics.
  

 

• Constant Volume - adjusts the audio volume (loudness) to a constant value across all tracks played. Useful for "party mode" when the volume control should stay untouched.
  

 

• Vinyl Emulation - get that special sonic character of a record player based playback chain. We also employ an emulation of the DMM-CD procedure offered by the Stockfisch label.
  

 

• Crosstalk Cancelling (XTC) - for the playback of dummy head recordings or live recordings via speakers for an incredible live sensation. Dummy head recordings usually are listened to via headphones because they only work properly if the left channel goes to the left ear only and the right channel to the right ear only. With speakers this is difficult to achive as the left channel goes to the left and the right ear. But with some clever signal processing of the speaker channels is is possible to suppress the crosstalk, i.e. the audio going from the left speaker to the right ear and vice versa. If that works properly then the recording sounds as if one would be in the space where the recording has taken place. All the reverberation and 3D representation of the sound sources is there.(For speaker based playback only.)
  

 

• Out Of Head Localization algorithm - tries to get the music "out of your head" when listening via headphones. The goal is to achieve a similar listening sensation as one gets when listening via speakers. 
  (For headphone based playback only.)
  

 
The following DSP algorithms are considered for implementation:

• Roon streaming.
  
  
• MQA decoding.
  
  
• Airplay.
