I can understand Bob's claims that MQA encoder has problems digesting test signals. It may not be designed to handle such extreme cases. But, the best way to counter objections is to provide some examples of properly MQA-encoded material that can be compared to the hi-res originals. What I don't...

Thank you for adding J-Test to the generator, John! One small issue that confused me at first: the frequency for J-Test seems to be set once on start-up of the generator. Changing sampling rate does not modify the frequency, and there is no way to adjust it after the rate change. The only thing...

Thanks, John!

Better! At 0 silence, THD+N of -107dB at 28Hz: 1 second silence and 20Hz high-pass filter. Seems identical: And here's the reason why, captured with 1 second silence but no high-pass filter as the sweep was progressing. My guess is that somehow the sweep isn't doing as much averaging as...

Looked the same, but the THD+N result was consistently a lot worse (below 300Hz). Noise trace is the reason why, except that N(oise) on the RTA screen is measured at -108dBFS and not at -76dBFS as it is in the sweep? Here's the mdat file (sorry, a new recording as I didn't save the original...

Hi John, Beta 33 fixed the sine sweep crash with the distortion harmonic phases -- thank you! I'm seeing something odd in the frequency stepped sweep. When I run the generator and measure distortions at the same settings as the frequency stepped sine sweep, the results for THD+N below about...

Sample rate was 44.1kHz. I didn't have the "Show Distortion" window visible on the screen when starting the sweep, but it was shown automatically when started. Harmonic phases check box was checked in settings. By the way, seems that closing the distortion window during a sweep causes REW to...

Hi John, Ran into a problem doing a stepped sine frequency sweep in beta 32. Error happened on step 19 out 29, FFT Length = 65536, Window: B-H7, Averages: 8, Max overlap: 87.5%, start freq: 31.5 end: 20000, step: 3, level: -10, silence interval: 5

I just logged in here to request a stepped level sine function in addition to the frequency one, and it's already added! Thank you, John!

Hi John, Any chance of adding J-Test (jitter test signal) to the signal generator? Regards, -Paul

Thank you, John! I can't imagine how this hasn't been reported and fixed yet with so many apps out there using Java.

One more work-around and a possible clue. Seems that this macOS setting causes the problem when it's enabled. When turned off, the problem disappears:

Stock macOS, nothing special installed or running to manage windows. Just removed and reinstalled REW and did a reset settings to default, just to make sure. I still get the same behavior when minimizing with the "on top" setting turned on. Must be something with my computer, some setting or...

That's it! If I turn off the setting to keep generator on top, the problem disappears. If I turn it back on, the problem comes back. This has been like this for many betas, which is why I said it's not a new issue with beta 9. Didn't realize there was such a setting, so at least I have a...

Nothing special needs to occur. Happens right away or in the middle of a session. The key is to minimize the Generator window. Here's a short screen recording, if you have Quicktime to watch it, starting from launching REW...
