NAME
audio2tape - Sinclair ZX Spectrum audio to tape file converter
SYNOPSIS
audio2tape [-t type] [-s] [-r] [-k] [-z level] [-c level] infile
outfile
DESCRIPTION
audio2tape converts audio files to ZX Spectrum tape images.
OPTIONS
-t type
causes type to be used as the level detection trigger. There are
two triggers implemented; the simple trigger just uses a
threshold value to convert to a one or zero on output, and the
schmitt trigger implements a Schmitt trigger which outputs a
less noisy signal, but requires a stronger signal to noise ratio
than the simple trigger. The default trigger is "schmitt".
-s causes the display of a frequency graph showing the sound levels
present in the audio file. This can be useful when selecting
good crossover points.
-r causes any ROM blocks that are recognised to use idealised
timing figures rather than the exact ones found in the audio
file.
-k causes the tape file that is produced to keep any audio data
from the original audio file that isn't recognised. This will
allow unsupported loading schemes, encryption tones etc. to be
preserved in the file that is produced.
-z level
causes level to be used as the zero point in the supplied audio
file, it allows adjustment for a DC offset in the audio file.
The default level is 127 from a range of 0-255.
-c level
causes level to be used as the Schmitt trigger noise threshold,
this reduces the sensitivity to noise in the provided file. The
default level is 8 from a range of 0-127.
infile specifies the audio file to be converted. This file can be in
any of the tape formats supported by libaudiofile.
outfile
specifies the output tape file. The format will be determined by
the file extension and can be in any of the formats
libspectrum(3) supports for output.
BUGS
None known.
