More details from Rational Acoustics ( Rational Acoustics announces the release of the first major version update for the Smaart v8 measurement platform: Smaart v8.1.

#Smaart v8 and high sierra free#

The update is free to all registered Smaart v8 users and may be downloaded from the website. So it's probably best to select MTW+ for the special use case of linearity testing (M-Noise) but use the defaults for general work, particularly if you have other programs taking in the measurement data or do a lot of work with saved traces.Rational AcousticsвЂ™ Smaart v8.1 is the first major version update for Smaart v8, which includes improved data handling as well as a host of new feature additions for usability, security and efficiency. It's not the new default because there's no real advantage over MTW in general use (when the system under test is linear, which is the underlying assumption we are beginning with for a transfer function measurement to be valid) and since the data point distribution is different, you can't average MTW and MTW+ data together, and it might confuse other applications that are pulling measurement data from the API.

#Smaart v8 and high sierra windows#

MTW+ uses a different arrangement of time windows including running end-to-end in the top two frequency ranges (where there are gaps with MTW) to do a better job catching nonlinearities as short as a single sample. Depending on when they happen they might fall between the gaps of the HF time windows in MTW. One of the ways that manifests is as distortion events that cause very quick drops in coherence. With something like the M-Noise test procedure, we are intentionally pushing the system and trying to detect the point at which it becomes non-linear. In the general use case this doesn't present an issue - we make the fundamental assumption that the systems we measure with Smaart are linear time-invariant (fixed relationship between output and input) so running more FFTs to fill those gaps doesn't really bring anything to the table, and doesn't change the answer we get. At HF, you are running a 10ms FFT every 42ms, so you have approximately 30ms of gap between one measurement frame and the next. So at LF, running a one-second FFT every 42 ms you have a lot of overlap from one frame of measurement to the next. MTW uses multiple time windows in parallel (hence the name), with longer time windows at lower frequencies and shorter time windows at HF (about 1s below 100 Hz and less than 10 ms in the top octave). Smaart updates active measurements 24 times a second (about every 42 ms). We've been working on this one for quite a while, lots of good stuff in there.
