OVER 2 YOU, 064 (22/01/02)
anyone aware of software that will enable an Audio CD to be played at slower than original speeds whilst retaining the correct musical pitch?
Brian Yabsley via E-mail
using GoldWave to slow down your CD, and retain the pitch. It won't actually slow down the CD, but it does allow you to alter the speed, and pitch, and other parameters of any CD track you copy to your hard disk.It's easy to use and a fully functional shareware version is available from
program which will allow audio CDs to be played slowly but at the correct pitch is Slow Speed CD Transcriber, which can be downloaded from: http://www.ronimusic.com/
The program is shareware and the unregistered version only allows the first or
last track on a CD to be played. Registration costs 40 US dollars. As well as
altering the playback speed the program can change the pitch of the music and
play selected parts of the track.
may already have some software on your system capable of doing this. If you
have a Creative Labs Live!1024 sound card, the utilities that came with the
card include a program to slow down audio CDs as part of the EAX technology
have a number of discs of personal letters on 5.25-inch disks created on a
Commodore PET, with an 8250 double disc-drive. The disks are dual-sided,
quad density (96 tpi), soft sectored. I would like to transfer them as text to
a PC. I still have an ancient Brother BCN 5000 with a 5.25 disc drive and
would like to transfer them if possible, before it gives up the ghost. Is
there a PC program, which would help?

am fairly sure it can be done, and if so the information, or a direct source of
help, can surely be found at: http://thisoldcomputer.com/links.htm.
This site is brim full of useful information and links to sites dealing with
all things related to Commodore computers, including a ghostly reminder of
‘8-bit nudity’, it was all so innocent back then!
simple solution would be to install a 5.25 disc drive on your PC, most models
have the necessary connector and the BIOS of most modern PCs will recognise the
drive and allocate it the mysterious missing drive letter ‘B’. Old drives are
regularly advertised in magazines like Micro Mart and can be picked up cheaply
at computer fairs. The data on the drive can then be read using a PC emulator
program like VICE, which can be downloaded from: http://www-2.cs.cmu.edu/~dsladic/vice/vice.html,
along with a lot of other useful information.
anyone know of any software or hardware that can be used to turn a PC into an
short answer is yes. However, it depends on what you want to use it for and whether you want to buy an off the shelf product or are prepared to construct it yourself.
The magazine ‘Everyday Practical Electronics’ has published designs of various complexities for home constructors over the last few years. These range from what is essentially a software solution (the electronics consist of a connector for the printer port, plus an analogue to digital converter chip) in the February and March 2000 issues, through a design published in October 2000, which makes use of a programmable microchip to reduce the complexity of the circuitry required, to a fairly advanced system published
in January and February 1998. The more sophisticated the system, the more facilities are available and the faster the waveforms that can be displayed. Further details, back issues and printed circuit boards can be obtained from their site at http://www.epemag.wimborne.co.uk/. Be aware
though that the complex designs are not easy to construct and make sure that all the parts (or their equivalents) are still available before you begin.
A kit is available at Maplin Electronics
(www.maplin.co.uk) for £186. Personally I would recommend their hand-held
'Velleman HPS5' at £125, which is very impressive.

oscilloscopes are used by electronics enthusiasts may I suggest the reader has a look through the electronic magazine Elektor Electronics (http://www.elektor-electronics.co.uk).
There are advertisers who specialise in cards that contain the necessary
analogue/digital/control processor chips and software that can be interfaced to
a PC for this purpose.
I believe one of the key factors governing price is the frequency of the
signals you wish to display - the higher the frequency the greater the cost.
Most of the "do it yourself" projects are designed for audio
frequencies (e.g. 20-20000 Hz). For higher frequencies it may be better to purchase
a purpose built oscilloscope (a good second hand model - 20Mhz/dual channel can be purchased for under £100).
The best (sensibly priced) system is
available from Pico Technology Ltd. They have a good range of sensors
and software to monitor electrical signals and can be contacted by email email@example.com or checkout their
website at www.picotech.co.uk
If Mr Kenny's interests are with audio, then there
are a number of software packages that operate with a PC sound card to form an
audio analysis suite without the need for any external hardware. Examples of
such programs are Analyser 2000 (http://www.5star-shareware.com/Utilities/
and SpectraLab (http://www.soundtechnology.com/

sometimes hear in my head music that I have never heard, but I can't read and
write music so my melodies go lost.
Is there any software that puts into written music, a tune I whistle or
is a shareware program, Music MasterWorks from www.musicmasterworks.com
that should help with Franco Cavallini's query about converting whistled notes into musical notation. It has a
"voice-to-notes" function, which converts voice to midi notes and
musical notation, and just requires a microphone and appropriate sound card.
Registration is $25 after the 35-day trial period.
physio has heavily criticised my sitting posture - which has added to the strain on my neck and the deterioration of my cervical vertebrae. He suggests that I find some way of regularly reminding myself to check my posture when operating the PC. Can anyone suggest a way of
reminders to my screen at regular intervals, irrespective of software I am using at the time?
Tom Busby, via email
You should visit: http://www.infinn.com/screamsaver.html there
you will find a program, which prompts you to take regular breaks. A
downloadable trial version is available.

I have a set of card and board games by Hoyle.
When playing the card games it deals itself the most extraordinary hands.
In cribbage it will frequently deal itself maximum point hands and
similarly high scores in its box. It does similar tricks in bridge.
If a human dealt like this he would get his fingers amputated. It can
seldom be beaten and is most annoying.
Is there a truly random dealing and shuffling
program one can download from the net?
J. Boxall, via email
I started to write small programs as a hobby many
years ago, and one of my first attempts was a crib program on an old Tandy
64K computer. My father-in-law fancied himself as a bit of a crib player,
and was very sceptical about a machine being able to play. I persuaded
him to have a go and, after the computer had soundly beaten him twice, he was
convinced that it was cheating, knew what he had, and chose the best
cards. He never went near a computer again! Although I considered I
hadn't done a bad job of teaching it, it was a fairly simple routine and the
deals were completely random. It is amazing what random numbers, and
consequently random deals will throw up, and J. Boxall will probably find that
the Hoyle card deals are already "truly random".
I have been looking very hard (but perhaps not hard
enough) for serious religious clipart.
I'm looking for the standard that would give, for example, two hands holding a
chalice, or two hands offering up a Sacred Host, plus of course any pictures of
the inside of churches. Yahoo, Jeeves etc. only show me email addresses, which
turn out to be standard 'comic' characters. I'm not looking for freebies.
Gordon Hackwell, via email
I have a CD called "Essential Bibles" (see http://www.softwaresavings.co.uk/
contains the type of clipart pictures Gordon Hackwell was looking for.
I seem to remember a few years ago you could buy a
receiver that would pick up images from orbiting weather satellites, as they
flew overhead. Do they still exist or are there any add-on’s for the PC? I’m
interested in studying ‘live’ real time pictures, rather that the images on the
web, which are often several hours or even days old.

there such a thing as a ‘wind-up’ computer or can anyone suggest a reliable
portable power source, as I’ll be off trekking in various out of the way places
later this year. Solar cells seem like a possibility but are they small or
efficient enough to drive a laptop and mobile phone?
