Notes on WHAM 1.1
-----------------
WHAM (Waveform Hold and Modify) is a Windows 3.1 application for
manipulating digitised sound. It can read and write Windows 3.1 WAVE files
as well as raw eight-bit digitised sound files, and can perform various
operations on this sound. WHAM can handle sounds of any size, restricted
only by memory.
New features in release 1.1
---------------------------
- WHAM can now read and write Creative Voice .VOC files, Amiga
IFF/8SVX sound files, Sun/NeXT .au (8-bit linear and Mu-Law)
and Apple/SGI AIFF files (although I cannot guarantee the
accuracy of the last format; at least one Macintosh application
rejects WHAM-written AIFF files).
- New display options. WHAM can now display the waveform at full or
half height, and in solid or outline form.
- Support for embedded information. WHAM can embed information (title,
copyright, date, software, artist*, engineer*, technician*, comments*)
in WAVE and IFF files, and read information that is in these files. If
I find information formats for other file types (and, preferably,
examples of these formats in use), I will add these.
[* WAVE format only]
- A more robust WAVE file reading mechanism (now recognises
information in files and acts accordingly.)
- More buttons at the top of the window.
- Many bugs/glitches have been removed.
Coming Soon
-----------
- More file formats. WHAM will be able to read (and, in most cases,
write) more types of files, as soon as I find new formats to
implement.
- Sound recording capability. As soon as I get access to a sound card,
I intend to put it in. (This release was coded using only a
PC speaker driver). Donations, anyone?
- Mu-Law and ADPCM support. Microsoft are putting support for Mu-Law
encoding and ADPCM compression in a new release of their RIFF
specifications. When I get access to an upgraded Windows multimedia
DLL, I will adapt WHAM to manipulate Mu-Law-encoded sound files in
native format and to read and write ADPCM-compressed sounds.
WHAM will then also be able to write Mu-Law .au files, as well as
linear ones.
- Support for 16-bit samples, stereo sounds, et cetera (...as soon as
I get some examples to experiment on and a stereo sound card.)
- High/low/band-pass filtering, independent pitch/speed changing and
other really good features, as soon as I figure out how to do them.
Any info out there?
