REW Beta Release REW API beta releases

[John Mulcahy]

As mainly measurement signal is not from REW output, only reasonable way is to use RTA and peak hold measurements.

If the measurement signal has a defined duration (e.g. a sweep) you can obtain the result from the normal input, though it is more awkward. Here's an example of capturing a 10 second log sweep using a 1M FFT (so the FFT spans 21.8 seconds at the 48k sample rate used). I started the RTA, waited for the first capture to complete, played the sweep then stopped the RTA once the second capture had been made. Rectangular window is used as the whole input signal fits within a single FFT span and to prevent attenuating parts of the capture. I had averaging on in the settings but it isn't needed or used in this case. This process could be automated using the API.

I will look at options for capturing and displaying individual input peak traces.
