                          INTRODUCTION

Resample makes it possible to play digital sounds sampled at any rate 
on the hardware present in Atari's STE and TT computers.  The 
so-called DMA sound engine has four playback rates available: 
(approximately) 6.25KHz, 12.5kH, 25KHz, and 50KHz.  Most digitized 
sounds are sampled at 8KHz, 11KHz, 15KHz, or 22KHz so they don't 
sound right played back with the new hardware sound.  Resample allows 
you to change the sample rate of sounds so that they sound they way 
the were intended.  Be careful, though.  If you resample a sound to a 
rate lower than the rate at which it was originally sampled, it will 
lose quality.

                       RESAMPLE'S FUNCTIONS

Load a Sound:
	Before doing anything else with a sound in Resample, you need to 
	load a sound.

Resample a Sound:
	Resampling a sound does the actual work.  Before clicking on the 
	resample button, be sure to set up the "parameters."  You'll need 
	to set the "original speed" to the rate at which the sound was 
	originally sampled.  Next, set the rate you want to change it by 
	clicking on one of the four "new speed" buttons.  If you want to 
	to play the sound back within the Resample program, you'll need 
	to select the "Convert to STE format" button.  If you plan to use 
	the sounds in other sound sample players, you probably won't 
	want to convert the sounds.  Programs designed especially for 
	the STE/TT digital sound hardware may expect the sound to be in 
	STE format.  You can experiment with turning it on and off to see 
	which gives you the desired result.

	(For those of you familiar with digital sound, the usual sort of 
	ST sound samples are in 8-bit unsigned format, while the STE 
	hardware expects 8-bit _signed_ samples.)

	(To convert KHz, kilohertz, to Hz, hertz, just multiply by 1000, 
	which amounts to putting three zeroes on the end.  Resample 
	expects the original rates to be in hertz, while they're usually 
	given in kilohertz.)

Play It:
	As was mentioned above, "Play It" uses the STE/TT hardware to 
	play back your sample.  If you try to play back a sound that 
	isn't in STE format, it will sound very strange.  To correct it, 
	click the "Convert to STE format" button.

Save It:
	Resample can save your new sample to a file after it's been 
	processed so that you can use it in other programs.  As was 
	mentioned above, you may not want to convert samples to "STE 
	format" if you plan to use them with older software.  An example 
	of a program that will use STE format sounds is DAPlay which will 
	be described shortly.  STE format files have the extender .6E, 
	.12E, .25E, or .50E.

REGISTERING RESAMPLE

Resample is shareware.  If you use it, you must register it by 
sending $10 to Steve Whitney.  For your convenience, you can send a 
"Gift of Time" of $10 to S.WHITNEY on GEnie to register.

Reegistered users will be able to get updates of Resample as well as 
another program called DAPlay.  DAPlay plays back digital sounds in 
STE format on an STE or TT machine.  DAPlay is a desk accessory which 
will playback sounds in the background while you use your machine for 
otehr things.  Lots of fun.  To get your copy, send a disk and a 
self-addressed, stamped mailer along with your registration fee.  (If 
you send a gift of time on GEnie, you can have DAPlay GEmailed to 
you.)  As a registered user of Resample, you will also be able to get 
a special price on any future sound tools I produce.

A few public domain sound files for the Macintosh are provide for you 
to try out.  I changed the names so that the extenders give the 
sampling frequency.  For example, HARP.11K was sampled at 11kHz which 
is equivalent to 11000 Hertz.

	Enjoy it!
