NAME
       audio2tape -- Sinclair ZX Spectrum audio	to tape	file converter

SYNOPSIS
       audio2tape  [-t	type] [-s] [-r]	[-k] [-z level]	[-c level] infile out-
       file

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 thresh-
	      old 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 tim-
	      ing 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.

       -h, --help
	      give brief usage help, listing available options.

       -V, --version
	      output version information.

       infile specifies	 the  audio  file to be	converted. This	file can be in
	      any of the sound 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 libspec-
	      trum(3) supports for output.

BUGS
       None known.
