How do I create an impulse response?

post #1 of 3
Thread Starter 

I like the bass boost feature on my meizu m6. Wondering if its possible to capture that somehow and create an Impulse Response out of it. I don't want to use eq because it doesn't sound the same. Thanks!

From an electrical engineering perspective, just input different frequencies between 20 Hz and 20 kHz and record the magnitude of the output.

ie play a sweep wave, plug your output to the input of a sound card, capture the response and plot the response

Actually this is creating a frequency response, which I believe is what the OP is after. An impulse response would entail inputting a dirac delta function and capturing the response and is a time domain characteristic.
