Hi,
First off, thanks for REW! It's a very nice tool.
I'm having some minor issues with it, none serious, but I thought I'd comment. My on-the-cheap setup is:
* Lenovo x120e laptop with Windows 10 and 8GB of RAM
* Dayton IMM-6, connected to the laptop's headset jack with a 25' "Kabelsdirect" TRRS extension cable
* HDMI to a Denon AVR-S740H and 7.1.2 speakers
* REW 5.20 beta 15 with the private-JRE installer
* ASIO4ALL
Since this laptop is so slow, I also have REW 5.20 beta 15 installed on a late-2014 27" iMac to review/analyze.
Things I've noticed:
* I'm also playing with some old non-measurement mics I have, none measurement grade. These all have 2 or 3 pin connectors, so I'm using an old consumer-grade USB audio dongle for them. Switching between mics on the headset jack and the USB audio dongle is painful. I have to do things like disable the other mic in Windows control panels, make sure the Windows control panel is not up when starting REW, making sure shared-mode sampling is set to 48kHz in the device control panels, and all sorts of other voodoo. It works, most of the time, after lots of poking. I think some of this is exacerbated by bugs in the USB-audio driver, bugs/flakiness with ASIO4ALL, etc, so it is clearly not all or even much about REW, but it is annoying and underdocumented. One thought: could REW use ASIO4ALL for output (for HDMI), but use other access methods for input? That might (or might not) ease a lot of this pain. Not super important, a better solution here might be an adapter cable.
* The x120e is a slow machine by modern standards, almost a netbook (except with more memory). The UI is painfully slow in some places, like doing measurements. It'll take around 5 seconds after hitting the Start button, just to redraw elements on the pane grayed out and such. Using Alt-uparrow will take 2-3 seconds to go from measurement to measurement, much of it doing the little tab-slide animation. Also, sometimes when I Check Levels on the measurement pane, the test tone plays and is shown on the running SPL graph, but "Levels Too Low" is reported and the numeric figure is that of the noise in the room, not whatever the speaker put out. I think the program misses the tone during its FFT processing because it starts the tone playback/sample recording fairly quickly, but the UI update takes several seconds. I also sometimes get clicks during sweeps (which of course I re-run). The proper answer to this is probably "find a faster laptop already!" (and I have a couple of possibilities) but this was the best candidate at the time. Is there anything I/we can do to lighten the UI? I suspect the running SPL graph on the measurement pane may be too heavy a load on this machine, can it be turned off?
* On my Mac (and Microsoft Bluetooth Mobile Keyboard 5000), shift-cmd-<N> to select different smoothing doesn't work, the display doesn't change. Sometimes I can see that it flips to the other state (smoothed/unsmoothed) and right back again, if the UI updates manage to show correctly. (Or at least it was doing this yesterday-- now the problem seems to be gone, it's working fine.)
* On the Mac: If you load a measurement set, move a measurement tab by dragging it up/down the list, and then Save All, you will get prompted for a file comment, but you will not get a file save dialog and no file write happens. (I'll guess your code thinks nothing has changed and nothing needs to be saved, it's *almost* right)
Again, thanks!
