I want to record sound with a piezo transducer. I am connecting it to my sound card's input which has a good mic pre-amp. The levels are quite good and the sound seems quite clear but there's a lack of low end.
I want to build an impedance-matching circuit to improve the sound, to make it full range.
My priorities are:
- Full frequency range and good quality sound.
- Simple to build, because I have very little experience in electronics.
- Must not cost a lot.
I've seen some options on the internet, but they are old and most include the functionality I don't need, introducing additional undesirable complexity.
I was wondering if there are now better and possibly simpler, modern solutions to this problem, possibly making use of the newer elements of better quality.
What would be a good approach to solving this, considering all of the above?
