Sound card "enhancements" option the problem. Thought that was permanently off. Latest Windows 11 update apparently turned back on since that is the only recent change. Thank you Microsoft!

Thanks, gives me troubleshooting ideas.

Using REW ver 5.30.1. Recently monitored waveform output from Laptop soundcard as frequency manually swept in REW. The P-P voltage varies up and down as the REW Generator frequency is manually swept from 20 Hz upward. Would expect the P-P voltage to remain constant regardless of frequency...

Interesting article. Going back to the 1980's, a period some called the golden years of Hi Fi, choices for quality equipment were many. All out negative reviews of equipment were few as were glowing reviews declaring perfection. Most I remember had a positive tone with a minor shortcoming...

The speakers are in the vintage category, commercially produced. Due to age started with replacing electrolytic caps with film. Ended up rebuilding the crossovers with good quality caps, air core inductors, and good quality resistors. X-Sim software to generate response curves with component...

Have tried the UMIK at 0 and 90 degrees using the correct calibration file. Forget where, but read a calibration file should be generated for PC/Laptop sound cards. Can generate one connecting headphone out to mic in. Far from flat. Definitely skews measurements. So, stopped using a...

Thanks. My Yamaha capability does not have the resolution to match the REW EQ profile. Tried to match overall best I could. For example, the REW profile recommended -3db at 632Hz, then +6db at 801Hz. Tried a near to speaker measurement with a sound absorbing shield. Shield on three sides...

Thanks. Read Spridle's Experiment. Good information that makes me feel better about trusting my ears. Backing up to some basics. Found conflicting advice about PC sound card calibration and microphone orientation. When using a USB mic (UMIK-1), it is stated no soundcard calibration is...

Have been working with REW and UMIK-1 mic for about a month. Think recent results are more accurate, but unsure. My listening room is roughly 10 x 12 with a sloped ceiling. Windows along one wall. Room treatment is needed, but not likely as it is multiple use room. Near, far, listening...
