NAME    [Toc]    [Back]

     g711conv -- conversions according to G.711

SYNOPSIS    [Toc]    [Back]

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

DESCRIPTION    [Toc]    [Back]

     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.

STANDARDS    [Toc]    [Back]

     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

EXAMPLES    [Toc]    [Back]

     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.

AUTHORS    [Toc]    [Back]
