Better use japa and then use the setting where the line isn't going
down (or is going down _very_ slowly). Use the accuracy as you like.

But somehow I suspect the "lowest frequency" will be some kind of
rumbling noise from either a mic stand or from some synths/effects
unwanted subharmonics. You should set a minimum amplitude below you
ignore a frequency as "lowest frequency". If you don't do it, you are
limited by 1/(2*window_length). And given that you have a) noise in
every recording/audio and b) a single almost delta-peak will have all
frequencies, you will also have frequencies down to the minimum
detectable by fft...

Have fun,
