Hi Hugh:

Yes, I think a high-fidelity full-range speech recording may (or may not) be negatively effected 
vis-a-vis intelligability. I have encountered almost no such recordings in now thousands of oral 
history and other amateur speech recording transfers. Only relatively modern professionally produced 
speech recordings would get noticeably messed up, especially if you EQ for audibility in the DSP 

But like I said, I wouldn't try that trick if I had a pile of high-quality recordings of a famous 
person known for their beautiful voice. Then again, I doubt they would have recorded onto cassettes 
in the first place, and if so I doubt they would have used a high-quality microphone. There are 
exceptions to everything in audio, but that was not the norm with spoken-word cassette recording.

On a related note, I think if you let loose the legions of amateur recordists who made thousands of 
interesting but poor-audio oral history recordings in the cassette era, with today's relatively 
inexpensive digital recorders, and give them minimal instructions about placing the recorder mics-up 
between the interviewer and interviewee, you'd get much better audio today. Indeed, even cellphones 
can do this job as long as the user knows where the microphone is located and positions it properly. 
I keep hoping someone will come up with an app that leads a rank amateur through setting up and 
capture an oral history with their iPhone or Googlephone. Such an app would include an indicator if 
the mic is too far away from the person speaking and if there is too much table-comb or room-boom. 
Ideally, the app would clean up background noise right away, and save a copy of the audio file to 
some "cloud" system so there's immediate backup.
