PUBLIC DOMAIN - FREEWARE
This document provides brief instructions into the use of the PLAY
sound sample replaying software. This is therefore not a demo version
and is not disabled in any way.
Why did I make it FREEWARE (I've had a couple of offers from
software companies for this!)? Well, because I'm a student and
hate software that I have to pay for, then find it is useless or
I could have written better... Shareware is a bit better, letting
you evaluate the package - but it's still a costly business.. By
making this software totally free I hope more people will enjoy
it and feel free to distribute it to friends!
WHAT DOES IT DO?
PLAY allows you to play and edit sound samples from a variety of machines,
AMIGA,ATARI ST and MAC samples have been played with great sucess through
the internal speaker. It has a few 'fancy' features as well!
WHAT DO I NEED?
To simply play a sample from start to finish, Nothing more than the
play.com file and the sound sample file
....any machine should do as long as it has a decent sized speaker and
MSDOS 3.00 or above (an 80286+ would be preferable)
If you have VGA graphics and a MOUSE installed the fun starts, allowing you
to look at the waveform and play bits of it - alter frequencies and do all
sorts of wierd and wonderful things.
HOW DO I RUN IT?
If you have VGA and a MOUSE driver installed just type
C:\> PLAY /?
to get a list of the things you can do from the command line.
WHATS THIS HARDWARE THEN?
By addition of a piece of hardware costing around 20 quid (to build) onto a
spare printer port you can sample your own sounds and replay them through
your hi-fi with really astonishing quality.
HOW CAN I GET A CIRCUIT DIAGRAM?
For a modest sum, I will send two 3.5" (Branded) High Density disks with
the latest version of PLAY and RESPLAY together with nicely printed
instructions and a copy of the circuit diagram. To obtain this
package, send 10 pounds (sterling!) to the address at the end
of this document! I make a little profit on each, but that will help
to cover the cost of the book I had to buy to improve my VGA routines!
HOW LONG A SAMPLE CAN I STORE?
It depends on what frequency the sample is and how much memory is free -
at 16kHz (the speed I like to sample at) I get about 33 seconds into
memory with no TSRs except a Disk Cache - I have a mac sample at 11kHz
of the entire Dr. Who. theme tune; Sorry, until I fathom how
to use Extended/Expanded memory it can't use it! (Well, I've now worked
out how to use it, just I can't get it to work!)
DOES IT CRASH?
Yes! It doesn't like programmes like DesqView - or any sort
of shell you run it from. Run it from DOS with no TSR's for
best performance.. If the Interactive version crashes, try using
it from the command line.
INSTRUCTIONS FOR USE
PLAY FROM THE COMMAND LINE!
Usage: PLAY [-k] [-options] 
-k = Select Play/Record speed in kHz (default 16kHz)
(in range 05...39)
Options: (more are displayed if you do PLAY/?)
-s = Play sample named through PCs speaker (Lo-Fi)
play -smarvin.smp - Plays the file test.smp at 16kHz
play -k05 -sa:marvin.smp - Plays the file test.smp at 5kHz from A:
(note leading zero required)
When sample has loaded it will automatically start playing and
can be stopped by pressing any key (and I mean ANY key!!)
There are a few other options such as recording from the command
line and setting which port the hardware is connected to and
doing echo's and things - but you need not worry too much about
them until Version 4.00!
Usage: PLAY (or PLAY /I)
(Useful hint: PLAY /k11/I will take you into interactive mode
with the frequency set to 11kHz etc... lets you create a batch
file that loads PLAY with some default values - you can also
do things like PLAY /k11 /l1 /i to set the port default as well)
If VGA board is installed then programme will show initial
screen. Although all commands can be acessed from the
keyboard, I'm afraid you will need a mouse + driver
installed due to a wierd bug I'm working on! (You can
operate it entirely from the keyboard you see)
The screen is divided into 3 areas, the top line contains some
buttons giving information on the program. Left Click on any
button to do that command, Right Click to get help on that
The next bit is a graph of the current sample.
The bottom section contains more buttons with lots of
The (blue) pointers can be moved by picking them up with the mouse,
or by using the control 'hot-spots' either side of the little
number indicators. The numbers give the time in Seconds at which
the pointer is pointing.
The middle number and surrounding 'hot-spots' is the frequency in
kHz and this can be altered in 0.25 kHz steps or you can jump to
11kHz,16kHz or 22kHz directly.
The various commands are not explained here, help can be got
by holding down the right mouse key when you are over a
Note: CUT/COPY/PASTE rely on a temporary file c:\play.cut, if you
don't have a hard drive you cant use these commands (sorry,
but it's too slow off a floppy - I'll let you change the
default in a later version so you can make it store on a
high-memory Ram Drive or something)
Even your favourite Mushroom and Mood samples can be played. Just
load in, select 'Shift Left' function twice, then take the frequency
down to 10kHz and BINGO! Not the best sound in the world but its a
bit better than the distributed player (and you get to fiddle with
the sample+ it sounds SUPERB through the hardware!)
Some sample files (MAC ones etc..) have small headers added to the
beginning of the file - if you play these as normal you will hear
a fraction of a second of noise before the sample starts -you could
always edit this out using the interactive version though!
