Re: Sound card will not calibrate

This is trying to calibrate the sound card. The lead goes from the speaker line out to the mic line in as per your earlier recommendation. There's no sound from the laptop speakers and I've disabled the in built mic.

Then it must be a setting with the sound card or operating systems’s recording/playback settings. If there is a monitor (i.e. that would let you hear the incoming signal as it is coming in) it needs to be turned off.

Re: Sound card will not calibrate

Also, we typically don’t find people using internal sound cards unless they’re using USB mics. Perhaps this is why, the configurations of internal sound cards can by “iffy” and possibly unable to be set up properly for REW use (e.g. the internal monitor I mentioned).

There’s plenty of information in the Help files and elsewhere on this site (e.g. the REW Sound Card Database sticky thread) for a good number of hardware options that are proven to work with REW. It’s when people opt instead to forge their own path that they run into complications.

That said, ultimately you might be able to simply forgo the sound card calibration. Even the ones that aren’t that great should be reasonably flat out to at least 10 kHz and down to about 30 Hz. Depending on your particular intentions for using REW, that might be good enough.

Regards,
Wayne

Re: Sound card will not calibrate

Worth attaching the .mdat file for your soundcard measurement for us to take a look at. Make sure that there aren't any audio effects active on the soundcard, you can check for them on the Enhancements tab of the Windows properties for the soundcard output.

Re: Sound card will not calibrate

Thank you, I'll investigate further. I was thinking that if it was okay I'd go with a USB mic. One thing I was looking forward to checking was how well I'd set up my sub..

Re: Sound card will not calibrate

Just a thought (having tried all variations in system settings), could there be a compatability issue with my Acer Aspire 5738 running Window Vista Home Premium 32bit with REW 5.1? G

Not very likely, no. Still worth posting an mdat file for us to look at, and screenshots of the Windows properties for your audio input and output.

John, here's the mdat file - default out and line in. I've tried all combinations and the results are almost the same. Set up picture to follow shortly. G.

Re: Sound card will not calibrate

There is an acoustic effect being applied to that signal (the type of thing that gets labelled 'Jazz club' and the like). If you click on Speakers and then Properties on the Windows Sound playback tab look for a tab called Enhancements and turn off all effects. There may also be some sound effects control amongst the icons in your system tray, bottom right of the screen.

John I've looked through all the tabs and settings and can't find any Eq being applied. G
