I think so. I'm not good with terms like hertz and knowing how to translate what I hear into the correct language. It's something like the tone control on a four-track player. When the control was slid all the way to the left, the tape sounded more muffled and had more bass. When it was slid all the way to the right, the tape sounded more crisp, with clearer high-frequency sounds, such as "s". I hope this makes sense. -----Original Message----- From: bookport-bounce@xxxxxxxxxxxxx [mailto:bookport-bounce@xxxxxxxxxxxxx]On Behalf Of Phil Parr Sent: Tuesday, November 22, 2005 9:07 AM To: bookport@xxxxxxxxxxxxx Subject: [bookport] Re: Pleas ignore. So, I surmise this is referring to the range of hertz at witch a particular voice speeks.

Frequency is totally different from pitch. It has to do with how much treble is in a particular voice. -----Original Message----- From: bookport-bounce@xxxxxxxxxxxxx [mailto:bookport-bounce@xxxxxxxxxxxxx]On Behalf Of Phil Parr Sent: Tuesday, November 22, 2005 7:05 AM To: bookport@xxxxxxxxxxxxx Subject: [bookport] Pleas ignore. Yes frequency is right their I just had never changed it. I find it to be almost a fine tuning of the pitch control, correct. Phil Parr.
