Teensy Audio Library Design Tool 101

Brief run down on how to use the PJRC Teensy audio library design tool.

Includes setting up a FIR LPF using coefficients generated by the Iowa Hills FIR filter design program.

Great video: Thank you very much !
Do you have a similar example with a FIR (low pass) filter ?
Or do you know where I can find an example of a program using a FIR ?

I have been searching for weeks without success !!....
Thank you for your reply,

Would love to understand those LPF coefficients enough to make a high pass and band pass filter. Then make all 3 adjustable, with potentiometers. Cut off frequency and roll off (think the roll off is often referred to as Q value).

Can i use the teensy audio library for something like a raspberry pi pico?

Hi sir, can i able to use this library for arduino due board which comes with the arm microcontroller

In this example i guess you'r using Teensy 3.6 and floating point arithmetic's. Can you do this demonstration on Tennsy 3.2? because it doesn't have Floating point unit. I'm bit confusing how to achieve fixed point coefficients for FIR design

Hi Charlie,
You sound kiwi. I'm currently building a Audio Multitool (custom audio board with SGTL5000) for use in Outside Broadcast work in NZ. Would be great to share a beer and compare notes on the Teensy Audio Library and use with SSD1306 displays sometime.
