Samplerate?
Microphone?

Initial sample rate was 44.1 KHz 24 bit. Target was 11 KHz 16 bit,
hence the 5 KHz bandlimiting.

Initial samplerate limits detectable components to 21.5 kHz

Microphone was never disclosed, though I asked. Recording was a voice
actress at Planet Sound.

Undocumented microphones generally limit detectable components to 17 kHz.

Which is to say that you know nothing about the upper frequency limit of the
white noise components in speech based on that recording.
