Is there a way to configure WinMLS (10c or the SineSweep Beta) for high-resolution (many data points) in the low-freqeuncy region (20-300 Hz or so)? I believe ETF v. 5 has a special low-frequency mode for this purpose (the MLS signal also sounds different, as it seems to be catered to low-frequencies).
I am trying to acoustically treat a basement for the recording of a string bass, and the first step is to assess the detailed low-frequency response of the room using WinMLS, but I find the number of data points in the low frequency region is small, even with a long window.
Also, is there a way to smooth the frequency response curves in WinMLS, e.g., by fitting a spline or curve through the points rather than straight lines. Other programs seem to do this (TEF and ETF), which makes the curves, especially in teh waterfall display more 'graceful'. Any thoughts good or bad on this?
All suggestions welcome!
Thanks,
Jon Longtin
