PlayCDDA - Play audio CDs on your Amiga's audio.device
------------------------------------------------------
Version 1.0 21-Nov-93 (C) 1993 by Frank Munkert
(ln_fmu@pki-nbg.philips.de)
INTRODUCTION
PlayCDDA is a program for owners of Toshiba 3401 CDROM drives.
These drives are capable of transferring CD-DA (digital audio)
data over the SCSI bus. PlayCDDA reads this data and reproduces
the corresponding sounds on the Amiga's audio.device.
DISCLAIMER
This software is provided as-is, without warranty of any kind,
either expressed or implied. In no event will the author be liable
for direct, indirect, incidental or consequential damages or data
loss resulting from the use or application of this software. The
entire risk as to the results and performance of this software is
assumed by the user.
REQUIREMENTS
AmiCDROM should work with any Amiga model which has a "SCSI-direct"
compatible SCSI bus adapter. A Toshiba 3401 CDROM drive must be
connected to the SCSI bus.
Your SCSI bus setup must have a bandwidth of at least 173 KB/sec in
order to transfer 44100 4-bit-samples per second. The higher the
bandwidth, the better. Also, while running PlayCDDA there shouldn't
be much other activity on the SCSI bus (e.g. hard disk accesses).
INSTALLATION
Copy the file 'PlayCDDA' to your favourite location for executable
programs.
USING PLAYCDDA
Invocation from CLI
You have to supply the name of your SCSI device and the
SCSI unit number of your CDROM drive as arguments to PlayCDDA,
e.g.
PlayCDDA scsi.device 1
invokes PlayCDDA with SCSI device name "scsi.device" and
unit number 1.
Invocation from WorkBench
Edit the tooltype entries "DEVICE" and "UNIT" of the PlayCDDA icon
such that they reflect your system setup.
Double-click on the PlayCDDA icon.
PlayCDDA communicates with the user over a simple graphical
interface. Basically, you have to click at the button for the
track you want to hear, and PlayCDDA starts playing this track
on your Amiga's loudspeaker.
The rest of the section explains the individual buttons of the
user interface.
"Start"
Click at this button to play the first track.
"Stop"
Stop playing.
"1" ... "20"
Click at on of these buttons to play the corresponding track.
"Next"
Plays the next track.
"Prev"
Plays the previous track.
"Volume"
Adjust the volume of the sound reproduction.
"Sampling rate"
The number of bytes per second that are sent to the audio.device.
The higher the sampling rate the better the sound quality.
"Buffers"
Number of buffers. The higher the number of buffers, the lesser is
the chance that the sound may be interrupted by other tasks with
higher priority.
You should adjust "Buffers" and "Sampling rate" to fit your system's
need. On an Amiga 3000T with built-in SCSI device, the default settings
should work.
