MMPPLLAAYY SSoouunndd TTooooll
MMPPLLAAYY is a mmuullttii--ffuunnccttiioonn sound player for Macintosh NON-AIFF (Audio
Interchange File Format), PC VOC, MicroSoft Windows WAVE files and MM/1
IFF or Amiga Monophonic IFF files. Amiga IFF Stereo files split the
channels. That is the right channel is stored first and then the left
channel. The MM/1 stores sound data as a word(16-bits). The upper
byte is the left channel and the lower byte is the right channel or
even bytes left channel and odd bytes right channel. MPLAY has two
modes of operation, interactive and silent. This utility plays
MONOPHONIC sound files only, except for IFF. If a file is 250K then
500K of memory will be requested. This is because the MM/1 always
plays sound in Stereo. A more elaborate method may be implemented in
version 1.02.

Use silent mode from a shell or procedure file. Frequency is specified
in Hertz. If a Mac or VOC file, frequency must be specified, otherwise
the default of 11000 Hz is used. If an amplification factor is
specified the sound will begin playing after it is altered.

Parameters may be in either uppercase or lowercase, or both.

Interactive mode requires a mouse, uses function buttons, and displays
a graph of the sound waveform. If the environment variable SNDDIR is
defined MPLAY will use this as the startup data directory. If not
present the current data directory is used. If a startup file is
specifed on the command line the data directory will be the current
directory. Button functions are:
Play - Play current sound in memory
File - Load, Save, and Convert
Amplify - Amplifiy or Attenuate
Freq - Alter sample playback frequency
Quit - Quit

PPLLAAYY
Play, plays the current sound in memory. While playing a scroll bar
will appear indicating the play position if the sound is large enough.
Due the the length of some sound files the scroll bar will not be 100%
accurate. This is because an OS-9 process can sleep for a minimum of
256ths of a second.
FFIILLEE
MPLAY does not rely on filename extensions, such as .wav, to recognize
file format. Instead it opens the file and looks for format specific
information. This allows you to use any extenstion, if any, desired.
Though, IFF files should have the extenstion ".iff".
LLOOAADD allows you to select a sound file to be loaded with the
mouse. If the enviroment variable SNDDIR is defined this is
where load will begin. If you change directories
SSAAVVEE rewrites the data section of the current file and allows
creating a new file of the save format. If the current file
is a WAV or IFF file the frequency will also be updated.
CCOONNVVEERRTT allows conversion of MAC, VOC, WAV, IFF to WAV, VOC,
amd IFF format respectively. Convert will convert any size
file IF you have the disc space. Sorry, VOC format conversion
is not presently supported. First you will be asked to
select the format to convert to, convert will abort if the
source is in the same format. The default format to convert
to is IFF, its button is depressed. Selecting another format
will raise it(unselect) and select your choice. Click on OK
to continue. Next you will be prompted to select the source
file with the mouse. If you click on the file selector close
box the conversion will be aborted. Then you will be asked
to enter the destintation filename/path.
AAMMPPLLIIFFYY
Use Amplify with caution, noticable distortion may be introduced.
Valid factors are 2 through 10 for amplification and -2 though -10 for
attenuation. A factor of 2 amplifies the most and 10 the least. The
same is true for attenuation. Amplify may be applied successively to
acheive lower or higher volume levels.

The lose of mouse is due to DMA activity. If lost, MPLAY recognizes the
'Q' key as quit. The Quit box recognizes 'O' OK Quit or 'C' Cancel.
