SYNOPSIS

g711conv [-a] [-u] [-P] [-A] [-R]

DESCRIPTION

The g711conv utility is part of the isdn4bsd package and is used to convert between the A-Law and u-law formats as specified in ITU G.711. It is based on a freely available and freely usable reference implementation done by Sun Microsystems, Inc.

The following options are available:

-a Convert A-law to u-law
-u Convert u-law to A-law
-r Reverse bits before conversion
-R Reverse bits after conversion
-P Print the resulting conversion tables (as C-source) to stdout instead of doing the actual conversion.

EXAMPLES

The command:
g711conv -P -a

prints out the A-law to u-law conversion table as C-source to stdout.

The command:
cat max_headroom.ul | g711conv -u -R > /dev/i4btel0

converts the u-law coded voice of Max Headroom to A-law, reverses the bits of the result and moves that to an active isdn4bsd telephone connection.

STANDARDS

A-Law and u-Law conversions are specified in ITU Recommendation G.711.

The reference implementation done by Sun Microsystems, Inc. is available from http://www.itu.int/itudoc/itu-t/rec/g/g700-799/refimpl.txt
