NAME

6       audio2tape - Sinclair ZX Spectrum audio to tape file converter

SYNOPSIS

9       audio2tape  [-t type] [-s] [-p level] [-h level] [-l level] infile out‐
10       file

DESCRIPTION

13       audio2tape converts audio files to ZX Spectrum tape images.
14

OPTIONS

16       -t type
17              causes type to be used as the level detection trigger. There are
18              two triggers implemented; the simple trigger just uses a thresh‐
19              old value to convert to a one or zero on output, and the schmitt
20              trigger  implements a Schmitt trigger which outputs a less noisy
21              signal, but requires a stronger signal to noise ratio  than  the
22              simple trigger. The default trigger is "simple".
23
24       -s     causes the display of a frequency graph showing the sound levels
25              present in the audio file. This can  be  useful  when  selecting
26              good crossover points.
27
28       -p level
29              causes  level  to be used as the crossover point between a level
30              of one or zero in the tape file output in  the  simple  trigger.
31              The default level is 127 from a range of 0-255.
32
33       -h level
34              causes  level  to  be  used  as  the low to high crossover point
35              between a level of one or zero in the tape file output  for  the
36              Schmitt trigger. The default level is 195 from a range of 0-255.
37
38       -l level
39              causes  level  to  be  used  as  the high to low crossover point
40              between a level of one or zero in the tape file output  for  the
41              Schmitt trigger. The default level is 60 from a range of 0-255.
42
43       infile specifies  the  audio  file to be converted. This file can be in
44              any of the tape formats supported by libaudiofile.
45
46       outfile
47              specifies the output tape file. The format will be determined by
48              the  file  extension  and  can be in any of the formats libspec‐
49              trum(3) supports for output.
