- WM DFTtoWAV There is more to life than increasing
- ─────────── its speed. - Gandhi
-
- WM DFTtoWAV converts compressed DFT files created by WM WAVtoDFT {WAVtoDFT}
- to playable WAV files.
-
- Note that there is a MUCH faster 32 bit version running in protected mode
- {DFT2WAV}. Use WM DFTtoWAV only if you have a 286 (!?!) or if you can not
- make DFT2WAV run properly for some reason.
-
- IMPORTANT: WM WAVtoDFT and WM DFTtoWAV {DFTtoWAV} run in real mode and use
- extended memory (XMS) to compress and decompress sound data. You
- must have HIMEM.SYS or equivalent (see your DOS manual) installed
- and a sufficiently large, contiguos block of free XMS memory
- available at runtime for the programs to run.
-
- Unfortunately, the algorithm employed is not suitable for the disk-based
- approach used by most other WAVmaker applications. WM WAVtoDFT and WM DFTtoWAV
- are slow enough as they are; if they were to work directly with disk files,
- they would be intolerable. BE PATIENT! Do not worry if they seem to have sent
- the machine to lunch - they haven't, they are just thinking!
-
- Needless to say, larger sample files require more memory. With 3 MB of free
- XMS memory, you should be able to handle 3 seconds' worth of sound data at
- the highest allowed sampling rate (44.1 kHz). Stereo channels are handled
- separately, so that's actually 3 seconds' worth per sound channel. The word
- size employed in the WAV file makes no difference as far as memory
- requirements are concerned, but it is reflected by the size of the compressed
- file.
-
- Usage: DFTtoWAV <source> [<destination>]
-
- If no <destination> is given, the <source> filename is used. The
- default extensions are DFT and WAV, respectively. The default
- directories are DFT\ and WAV\; you can override these choices with
- the /DFT and /WAV options.
-
- Options: /DFT <source directory>
- /WAV <destination directory>
- /q (quiet mode: no screen output)
-
- The following title:value pairs are written to WAVmaker's public Function key
- file {FnKeys} upon successful termination:
-
- File #1 : <source>
- File #2 : <destination>
- DFT file : <source>
- WAV file : <destination>
