Sample Editor V1.0
------------------
This is a little something I decided to write when I lost the manual to my
Prosound Designer software, preventing me from running it fairly
conclusively!
When you start Sample Editor, you'll be presented with the main edit
screen, which has all the editor functions available on it rapidly followed
by the file load requester prompting you to load a sample (or file
containing a sample to be ripped out(!).
Explanation of functions
------------------------
Load - Does this really have to be explained? It's the first thing that
happens when you start up. OK, it gives you a standard AMOS file
requester from which you can select a file or sample to play with.
Save - This one's tricky, too! Allows you to save your edited sample -
again through a standard AMOS file requester.
Quit - Aaargh! The complexity of it all! This quits the program.
Careful, though, 'cos there's no 'Are you sure' for this!
Display - This will cause the sample's waveform to be displayed in the
waveform window. Use this after a Start+/- or End+/- function.
Freq+ Increase the sample frequency by 1Hz
Freq++ Increase the sample frequency by 100Hz
Freq- Decrease the sample frequency by 1Hz
Freq-- Decrease the sample frequency by 100Hz
Start+ Move start point forward 2 bytes
Start- Move start point back 2 bytes
Start++ Move start point forward 100 bytes
Start-- Move start point back 100 bytes
End(xx) All end commands work as the start commands, but on the end
point(!)
Reset - Recall the sample that was orginally loaded to be re-edited.
Useful for those cock-ups which naturally you never ever make!
Compress - Halve the length of the sample. Useful for saving memory if
the sample is to be used in any of you own progs.
Expand - Double the length of your sample. Opposite of Compress.
Diode - Hmmm... How to explain this rationally? Errr for the electronics
engineers, this effectively renders the sample of a single
polarity, as would a bridge-rectifier sort-of-thing. For the rest
of you it sort of turns the top-half of the sample (only) upside
down into the bottom half of the sample. Best tried to be
understood...
Copy - Write current sample section to buffer for playing with later.
Cut - Removes the current sample section from the overall sample. This
does not buffer it, so use copy before doing this unless you
want to delete the sample section entirely.
Paste - Replace section of the sample from the current start point with the
contents of the buffer.
Insert- Insert the buffer contents at the current start point.
Merge - Mix the buffer contents with the sample from the current start
point.
Buffer- Replay the contents of the buffer.
+dB - Increase the overall volume of the sample by 20%. If the maximum
dynamic height (maximum space for the loudness of the sample in
the window) of the sample is exceeded, then distortion will occur.
-dB - Decrease the overall volume of the sample by 20%.
Distort - Produces a type of distortion by linearising the sample above
the distortion threshold. Clip - Clip the sample above the
clipping level. Produces distortion similar to that produced by
overdriving a basic transistor amplifier (no, NOT a MOSFET, as
these distort similarly to valves!).
Full - Restore start and end points to full length of sample.
Reverse - Reverse the sample.
Echo - Not implemented on V1.0. Echo can be achieved by use of the Merge
function, offsetting the buffer from the start point.
Ring - Aha! Where's the BBC radiophonics now? (Probably playing with six
Synclavier 9600's with WORM CD mastering!). Effectively modulates
the current sample section with a square wave. Enter the frequency
from the keyboard. If you have any speech samples, try Ring at
about 35-40Hz.
Loop - Loops the sample section. Click loop again to stop.
Tidy - Attempts to avoid memory fragmentation problems by saving the
current working sample areas to disk, erasing all workspace and
reallocating it, loading back the samples (buffer included).
