1K Club - QQ Shooting Star
An update on progress ))
The decoding software is now working well and I'm very happy with a decode of several DSOTM tracks performed yesterday. The sound is nothing like a conventional single or 3 band decode with complete absence of pumping artifacts and solid positioning of instruments. It turned out best to filter vector modification across all 10 bands to around 5-7 positions/sec. Decoding accuracy is better than a few decimal places from 10Hz - 20kHz although that is with test tones and real life especially with vinyl is never that good. I've also implemented dynamic phase correction, which eliminates the traditional 180 degree 'hole' thus all sound sources between speakers are in phase.
Next job is to eliminate a very low level noise from the vector modification filters and implement QS followed by Matrix H.
I'm very impressed Malcolm! Is this all for you personal amusement or are you working towards something saleable?
