TOPIC:

For a long time we've been asked to write a primer article on FIR filtering. Well here it is!
Audio FIR Filtering

It includes some digital audio basics, FIR and IIR filter structures, and complexity comparisons. Whilst pro audio products (today) typically support FIR filters between 384 to 2048 taps, some miniDSP products like the openDRC can run >6000 tap filters and have lower low-frequency reach.

Kind regards,

This is great Thank you Michael.
