GRADIENT/REVERSED END FIRED WITH BACK WALL   Leave a comment

In this post I positioned a Gradient Sub Array with the same settings as in the blog post: https://timobeckmangeluid.wordpress.com/2021/04/15/gradient-delay-vs-fir/ near a wall and adjusted eq and level a little to get a “better” respons (better means the max reduction at the back wall mic’s and hopefully a better respons on the on-axis mic) . Normally with just 1 sub the reflection from the wall at the back will cause a (couple of) dip(s). More on this can be found in a blog post from 2 years ago https://timobeckmangeluid.wordpress.com/2019/08/12/subs-omni-or-nomnie-part-3/

Front Back Front Delay vs FIR   Leave a comment

Did the same experiment with a Front Back Front set-up as the Gradient set-up in the blog post before this 1.

Also i wanted to see if this array would still work when positioned in close proximity of a wall (1mt from the back of the array in this case).

GRADIENT : DELAY VS FIR   1 comment

During today’s advanced training the subject on Delay vs FIR on subs came up.

The result was sort of ok on both but i decided to record the result of Delay vs FIR

PROCESSING PART 4: POWERSOFT X8 Dante   Leave a comment

The same as the other posts on the Lake LM26 Apex Intelli-x2 and the Linea Research asc48. (https://timobeckmangeluid.wordpress.com/2020/12/17/processors-interim-report-lake-lm26-vs-apex-intelli-x2-vs-linea-research-asc48/ )

No x-over filters at this time (hopefully there will be when i find time to do the measurements). As far as i can remember the Bessel 1-8 order filters are set at the -3dB point (so roughly the same as the Apex if i remember correct) Butterworth an Linkwitz-Riley are the same as all previous platforms.

So now the same set-up as before but not via cascading 2nd order All-pass filters but using all goodies available via FIR Designer M.

CASCADING ALL-PASS FILTERS VIA FIR   Leave a comment

This is a follow up on the post on cascading 2nd order all pass filters https://timobeckmangeluid.wordpress.com/2021/03/15/cascading-2nd-order-all-pass-filters/

The same thing can be done via FIR.
