Many of us who have used notetakers such as the Braille 'n Speak are = familiar with the BookPort's use of pitch and frequency. Pitch is just = the "note" at which a voice speaks. Frequency is, as you suggested, = something like bass/treble. I'm having trouble understanding where the = problem is, it seems very obvious to me. But, of course, that's just = me. -----Original Message----- From: bookport-bounce@xxxxxxxxxxxxx [mailto:bookport-bounce@xxxxxxxxxxxxx]On Behalf Of ptorpey Sent: Tuesday, April 12, 2005 2:58 PM To: bookport@xxxxxxxxxxxxx Subject: [bookport] Are there better terms to use instead of pitch and frequency? I am still confused by the use of the terms pitch and frequency in the Bookport settings - I don't think these are descriptive and/or being = used correctly. Maybe one of these settings is actually what might more = commonly be called (tone control" or "treble/bass" settings? Here is the definition of pitch from according to the American Heritage Dictionary: From the on-line American Heritage Dictionary: A. Acoustics. The distinctive quality of a sound, dependent primarily on = the frequency of the sound waves produced by its source. B. Music. The relative position of a tone within a range of musical = sounds, as determined by this quality. C. Music. Any of various standards for this quality associating each = tone with a particular frequency. and Pitch >>> original note from: Date: Fri, 8 Apr 2005 08:43:48 -0500 From: "Sarah Cranston" <cranston.sarah@xxxxxxxxxxxxxxxxx> Pete, Here is what I consider to be the difference between pitch and =3D = frequency. Pitch is almost like the particular musical note at which a given voice = =3D speaks. For instance, most women speak at a higher pitch than most men. Frequency, (according to my ears), seems to be the amount of treble =3D = and/or depth a voice has. A very high frequency voice provides a lot of =3D = treble, while a very low frequency voice is deep. I hope this makes at least a little sense. I hope anyone with a more = =3D cogent explanation will hold forth.
