OVERVIEW.TAPWAV - Version 2.2 by Luigi Di Fraia, Jul 2002.Windows long filenames support by Giuseppe Mignogna.Thanks to Fabrizio Gennari and Mike for testings/suggestions.This MS-DOS utility will convert tapes in C64 .TAP format (used by some C64 emulators) to 8-Bit Mono .WAV files so that you can play them on your PC and record back to tape to play them on a real C64.II.OPTIONS AND COMMANDS.TAPWAV.EXE [] Options are: -f to specify sampling frequency of output. Default is44100 Hz. -r to reverse samples in output file. Default is DON'T reverse. -b to force long pulses being handled as blanks. Default is no forcing. -ntsc to use NTSC timing. By default PAL timing is used.The "-r" option must be used just in case your Souncard reverts samples (in which case your tapes won't work without using this option).The "-b" option is "experts only". Don't use this option if you are not sure it's needed, neither if WAVs you generated seem not to work - in which case you may contact the author. The "-ntsc" option doesn't comply with documented Hakan Sundell's TAP format (which uses PAL timing), but it was added since Mtap from Marcus Brenner can use NTSC timing to generate TAPs. Don't use this option if you are not sure it's needed, neither if WAVs you generated seem not to work - in which case you may again contact the author. III.

TIPSTo record a WAV file to tape you need a tape recorder and a WAV player. The latter is easy to find (under Windows the MS Media Player itself is enough - but I would suggest to find one under MS-DOS and work under MS DOS itself), but for the recorder, you should note the following things: 1. a mono channel recorder would be better. In case you just have a stereo one, it's enough (-better-) to record right channel (I found some tapes where there was signal just on the right channel - or it was mainly in that zone and I couldn't detect its width with a stereo player); 2. set the player volume on your PC at a medium level, then set the output volume of your recorder to zero (to avoid hearing the wav file while recording it) and a recording volume low (half volume should fit); 3. if your recorder has a VU Meter, you can adjust these starting settings to optimal ones during recording. Just be sure that when data is sent (keep watching for 20-30 seconds about) your VU Meter indicates at least -3db and doesn't exceed +3db about. In case you don't read such a range, adjust your player volume and when ok, restart recording from the beginning.
