# audio2tape(1)

Sinclair ZX Spectrum audio to tape file converter

## 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.

- \-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 [*libspectrum*(3)](/libspectrum/3.md) supports for output.

## BUGS

None known.
