I'm having the same issue. It's almost like feedback. I'm recording from an audio-technica usb turntable to an iMac running 10.14.6.

That sounds like noise on the USB power line.
You could try using a USB lead that has a ferrite choke and see if that gives any improvement.

Is anything playing through the "PHL 276E8V" device?

You could try https://musescore.org/en
or Cakewalk by BandLab
There are others.

The apparently higher noise level at low frequencies is misleading. If you plot a higher frequency sine tone (say 10 kHz) and set the X scale to linear, you will see that the noise floor is fairly evenly distributed. The quantize error for 16-bit data is +/- 0.5/(2^15) = 1/65536 = 0.000015259 Conver...

Have you tried my last suggestion?

This is going off topic, but are you aware that you can run the official Audacity release as a portable app? You just need the ZIP version, unzip it, and add a "Portable Settings" folder inside the application folder.

The quantize noise floor for 32-bit float is below -700 dB. Audacity doesn't support 32-bit integer, but yes that would have a quantize noise level of around -190 dB.

have seen this "phenomena"

I'm not clear what precisely you mean by "this phenomena".

This is an export from the Audacity Spectrum dialog box: That isn't showing dynamic range of the audio, it's just showing the limitations of FFT analysis. If the analysis (and graph) were "perfect", there would be an extremely thin vertical line at 1000 Hz and the digital noise level woul...

Yes, that's what I meant.
