Revision 3.
CONDITIONS OF USE.
Amendment: this version is hereby released to the public domain
without any need to register. Donations are gratefully received
however and will do no harm to my eagerness to make more
public domain software.
It would be preferable if the ZIP file is kept intact and untampered
with for distribution.
INFORMATION.
Wavemod stands for Wave Modifier. Pretty boring name, I know,
but waved, wavchg etc. sounded worse at the time.
INSTALLATION.
Copy wavemod.pic into \OPD, then
copy the four source files - *.OPL into the OPL directory on your
ram drive and compile (Psion-T from the OPL editor) each one. This
will result in the file WAVEMOD.OPA being created in the /APP directory.
Then select 'install' from your APPS directory on your system screen
and select (guess what) 'WAVEMOD.OPA'. Voilá.
USAGE.
Once you are in the program itself, hitting the menu button will
supply you with a plethora of options. Just highlight what you
want to do, press return and pow! - bob's your uncle.
A basic rule to remember is that psion-letter usually applies to
the sample as a whole, and psion-SHIFT-letter applies to the
currently highlighted region.
MOVEMENT.
Cursor keys move the cursor.
Shifted cursor keys highlight a region.
Shift-psion-cursor keys change a highlighted regions LEFT border.
(As opposed to its right border, dummy)
Ctrl-(above) accelerates the cursor movement by a factor of 10.
ZOOMING.
Mark a region and then press Psion-Z. This will zoom the window
to the region. Psion-shift-Z will zoom out by a factor of two.
(if you are too close for your liking). If no region is marked
Psion-Z will zoom out to the full size sample.
BACKUPS.
Before making ANY change you will always be prompted whether you
want to make a backup or not. Selecting YES will copy the sample
to a safe place, so if you make a mistake you can 'Revert' back to
the backup with Psion-shift-V.
Warning: If you exit Wavemod (Psion-X) the backup file is deleted.
DISK SPACE.
Make sure you've got plenty... at least three times the length of the
sample you're editting if you want to make a backup. And NEVER edit
samples on flash, god no.
Someone give me a flash card and I will program wavemod to be able to
use them nicely.
EXTRA NOTES.
Phasing a sample of your voice several times with differing values can
have pleasant effects.
When filtering, the percentage value should be kept small.. eg. 2-5%.
I always find the best results on 50Hz, 5%.
When fading if your peaks and troughs get over-extended (oo-er! enough of
that young lad!) they will be clipped at the maximum. This can have a
nasty effect causing clicks in the sound.
TECHNICAL NOTES.
The A-Law tables are generated by a piece of assembler code written
by gsg@cix.compulink.co.uk and his marvelously magnificent spuriously
random character generating assembler. Apply now for his voice
recognition program. You can't go wrong... well with an error margin
of 70% you can't go *too* wrong - no I said 'too' not 'to' - no I said
'too' not 'tooth'.. bah. :^D
Also take a look at S3C, which is a Small-C compiler that runs on your
series 3 or series 3a. (the file at the time of writing is s3c101.zip)
And coming soon from the gsg stables are SLIP TCP/IP drivers for your
s3/s3a - put your psion onto the world wide web - and read your mail
using the Takoyaki software mail reader, all of which will be coming
soon to an ftp site near you. (e-mail for more details)
BUG FIXES.
v1.10 to v1.11 has only one bug fix. The menu key didn't work if caps
lock was on. No other bugs have been reported, so I assume there aren't
any?
Amendment: samples over 64k (10 seconds) cannot be recorded. I haven't
found the exact reason for this bug yet and I am a little busy with
work (and developing apps for the TCP/IP drivers mentioned above), so
if someone manages to scout out the reason I would be very
happy.
