I’m attempting to do some voice recordings and for some reason my setup has started clipping all audio recordings at about 7200Hz. It’s obvious when doing Analyze > Plot Spectrum that stuff’s being clipped. I checked my old audio recordings and they have the full spectrum of input, and nothing’s changed in my setup so I’m assuming some default setting has come back on but I don’t know where to start.
This is a RODE NT-USB. The input is set to the microphone, and the output to my bluetooth headphones. I’m using mono tracks at 44100Hz, 32 bit. Nothing obvious in control panel or audio settings out of place. Help very much appreciated.
Maybe a dumb question, but are you recording something that goes over 7200Hz? Does it sound OK?
Just FYI - Clipping has a different meaning in audio terminology. Clipping is the kind of overload-distortion you get if you try to get 110 Watts out of a 100W amplifier or when you try to go over 0dB digitally.(1)
…I’d say frequencies above 7200Hz are “cut off” or “missing”.
(1) DACs (recording), ADCs (playback), and common audio formats like regular-WAV or CDs are hard-limited to 0dBFS and they can’t go over. It’s the highest you can “count” with a given number of bits". Audacity uses floating-point internally so for all practical purposes it has no upper (or lower) limits.
