wavedit v0.1
by Aaron Goldstein
Well, I haven't seen any other waveform editors that work under Linux, so I decided to write one. This program is presently very simple - it supports loading/saving waveforms (not very well), and a few basic clipboard operations (cut, copy, paste, trim to selection). It's presently written entirely in C++. There's no particularly good reason for this, except that I need to learn C++ a bit better for my CS classes. I'm releasing this copy (instead of a good one), because I want help/suggestions/random comments/etc. for this program.
About the program:
wavedit recognizes the following commands:
(all of these are lower-case ONLY)
clipboard operations
x - cut the selection and place it in the clipboard
c - copy the selection to the clipboard
v - paste the clipboard to the current mouse location
z - trim waveform to the current selection
space - clear current selection
other stuff
p - play waveform
Plays either the entire waveform (if there is no
current selection), or the selection (highlighted
area) if there is a selection.
This is one of my first targets for improvement, since
the program doesn't do anything else while playing a
wave (including updating the mouse pointer).
s - save waveform to disk
Watch out - my line editor really needs work
q - quit program
Be careful - it assumes you know what you're doing.
If you just spent 2 hours trimming your waveform to
be just exactly how you like it, and then quit
without saving, wavedit will not complain
mouse interface
left-click / drag
This will select a portion of the wave, and high-light
that piece of the waveform. Clipboard operations will
affect this highlighted portion of the wave (except
paste, which pastes the clipboard at the current
x-location of the mouse, and sets the selection to the
newly inserted section of waveform).
middle/right buttons do nothing, as of now
About me:
I'm presently a sophomore in computer science at Carnegie Mellon
University in Pittsburgh, Pennsylvania. I'm originally from a tiny
little town called Valley Cottage, in the suburbs of New York City. I
can be reached at any of the following three e-mail addresses.
ag4z@andrew.cmu.edu (most likely to reach me) breadmold@breadmold.pc.cc.cmu.edu (preferred, but not always online) breadmold1@aol.com (if you feel like waiting)
- Credits
- I lifted code from a couple of different places, and just generally feel like giving credit where credit is due.
Thanks to -
Linus Torvalds for Linux!
Hannu Savolainen for the voxware sound drivers
Brad Pitzel - I've stolen a little code from his soundIt
library and demos (get it...it's really cool), and
plan on stealing more, once I've properly dissected
soundIt.c!
Michael Beck - format.h is an abbreviated version of
'fmtheaders.h', which is part of the source code for
vplay (a very happy little program). Thanks much.
All my friends who listened to me babbling about this thing
while I was writing (and who will have to continue to
listen to me, while I improve it). Especially thanks
to Noah, who I've babbled at the most (and who has, on
occasion, given me some useful tips).
Random/Important stuff:
I'm distributing this program completely free of charge. Give it to
anyone and everyone you want to. Give it to people you don't want to.
Threaten your neighbors with my source code. Whatever you like.
However, I'd really appreciate it if you'd credit me when using my
source code in one of your programs (I'd be even happier if you'd send
me a copy).
The current version of wavedit can always be found (using anonymous ftp) at 'breadmold.pc.cc.cmu.edu' as the file '/pub/software/waveditvX.X.tgz', where X.X is the version number (v0.1 is current as of this moment).
wavedit was compiled using voxware v2.9-2 (if anyone asks, I'll compile it under v2.5...I was just too lazy to actually go and recompile something else in order to distribute this), and svgalib v1.11. I used g++ v2.5.8, and libc v4.5.26 to compile it.
Hope you enjoy this program.
