This software is very useful for helping me find Loudspeakers with Rub & Buzz, but I was wondering what it would take to get the higher order harmonics in the Distortion Panel (RTA).
Depending on the speaker, Rub & Buzz shows itself between N = 10 and N = 50 harmonics. Right now I just excite at...
I've been using this software... at first for fun... now to try to start a product. As an Electrical Engineer myself I was blow away by how much functionality has been added to the software and I kept wondering who this John guy was and what motivated him. Thanks for this little write-up.
Update: For the UCA202 the Windows 10 drivers do not actually create 2 input channels. It only uses one channel but repeats it on the other channel, but doesn't tell you. The work around is to install an older driver. Specifically: BEHRINGER_2902_X64_2.8.40
Now things are working much better...
You're right, it's not different sampling rates, I confirmed by looking at the scope data on the scope panel. I'm using a UCA202 by behringer for input. For output, I've tried the headphone output on that audio card as well as the PC and Docking station. I can hear the speaker during the test...
I feel like I'm missing something basic. I'm an Electrical Engineer with lots of technician and audio experience. But with the recommended setup, I'm not able to really get any readings from the Impedance measurements. Nothing shows up. I'm slightly suspicious it's related to different sampling...
First: This is beautiful & powerful piece of software that I'm very happy to support and encourage others to donate!
I have a Bluetooth speaker that I'm trying to create and have some questions:
1) Do the SPL and distortion measurements work when the audio output is via a Bluetooth signal?
2) I...
