Denial WAV2MP3 Command Line Utility v1.06 (14oct97)
Copyright (c) 1997 Denial Corp., All rights reserved


--- Introduction

This application:

- is a command line application, which optionally uses GUI
  for selection of ACM codecs

- uses a Windows ACM codec to compress
  *.WAV files to MPEG Layer 3 format

- is command line parameter compatible with the 
  Fraunhofer L3ENC.EXE utility, but is several times faster
  with the equal sound quallity

- by default uses the Fraunhofer Windows ACM codec shipped
  with the free Microsoft NetShow Player v2.0
  or the commercial Fraunhofer/Opticom MP3 Producer

- can (probably) be used with any L3ENC GUI frontend application


--- Syntax

This application uses a subset of the L3ENC encoder. Unsupported
parameters are simply discarded. This application also adds
a few specific commands, which are preceeded with a "_".

dwav2mp3 <infile> <outfile> [-hq]

<infile>   required filename of the existing source file
<outfile>  required filename of the destination file to create
[-hq]      optional parameter to use the best possible sound quality
           Takes about three times as long time to create
[-dm]      optional parameter to use downmix to mono
[-_acmgui] optional parameter to show gui for user selection of ACM codec
[-_freq]   optional switch select frequency'

Example:
  dwav2mp3 infile.wav outfile.wav -hq

A DOS errorlevel 1 is signalled if an error occurs.

--- Why is the result a WAV file, and not an MP3 file

Since this application uses a Windows ACM codec, it creates *.WAV files.
The WAV file is an MP3 file with a WAV file header.
The WAV format makes it possible to play the file using any WAV file player,
for example the Windows Sound Recorder or the Windows Multi Media Player.

You do not need to remove the WAV header is you use WinAMP, since it
simply ignores it.

If you want to strip the *.WAV header, and create a *.MP3 file, you
can use the StripHdr.Exe utility shipped with WinDac32 v1.31,
or any other WAV header stripper.


--- Requirements

Before you start using this application, you must have an
MPEG Layer 3 Windows ACM Codec installed.

You have two option:

1) The free codec shipped with Microsoft Netshow v2.0
   (http://www.microsoft.com/netshow/download)
   Supports up to 56 kbps MP3

2) The commecially available Opticom MP3 Producer
   (http://www.opticom.de/producer)
   Supports up to 128 kbps MP3


--- What's new

Changed in v1.06 14oct97:
  Added percent done counter

Changed in v1.05 12oct97:
  Added parameter "-_freq xxx"
  Changed parameter "-_us" to "-_guiacm"

Canged in v1.04 25sep97:
  Added support for "-dm" parameter for downmix mode
  Added support for "-_us" parameter for user selection of ACM codec

--- FAQ

- If the resulting WAV is only 56kbps you probably only have the NetShow
  MP3 ACM codec. Uninstall NetShow and install Opticom/Fraunhofer MP3 Producer.

- There is no "percent complete" counter yet. Maybe in the future.
  Don't mail me about it. I know you want it.
