raw2audio - convert raw audio data to audio file format

---

SYNOPSIS

AVAILABILITY

This command is only available with the Demos installation option. Refer to [a manual with the abbreviation INSTALL] for information on how to install optional software.

DESCRIPTION

raw2audio adds an audio file header to the named raw data files. The encoding information in this header is taken from the command line options.

If no filenames are specified, raw2audio reads raw data from the standard input stream and writes an audio file to the standard output. If a target file is a symbolic link, the underlying file will be rewritten.

OPTIONS

-f

Force. If an input file already contains an audio file header, raw2audio ordinarily prints a warning message and skips the file. If the -f flag is specified, the old file header, including the `information' field, is replaced.

-c chan

Specify the number of interleaved audio channels in each sample frame. If not specified, a single channel is assumed.

-e enc

Specify the encoding type. enc may be one of the following: ULAW, LINEAR, or FLOAT, corresponding to µ-law, integer PCM, and IEEE floating-point formats, respectively. If not specified, µ-law encoding is assumed.

-i info

Specify the `information' field of the output file header.

-o cnt

Specify the number of bytes to skip in the audio data stream. This option may be used, for instance, to extract audio data from files containing unrecognizable file headers.

-s rate

Specify the sample rate frequency, in Hz. If not specified, the sample rate defaults to 8000 Hz.

-p bits

Specify the sound unit size, in bits. If not specified, the precision defaults to 8 bits.

-?

Help. Print a command line usage message.
