Readme for wav2mp ver 1.1

wav2mp is a simple command line audio mpeg encoder that runs at the command prompt under Windows '95, '98, me, NT, or W2K. Copy the file wav2mp.exe to any directory in your path. C:\WINDOWS\COMMAND or C:\WINNT should work for most people.

Invoke the program with the following syntax:

wav2mp [-options] inputfile.wav [outputfile.mp2]

     where options can be:

          -l layer       specifies which audio layer to use, 
                         valid values 1 or 2. (default 2)

          -b bitrate     Where bitrate is audio bitrate in K bits/s 
                         (default 128)
             Valid values for layer 1:
                  32,64,96,128,160,192,224,256,288,320,352,384,416,448
             Valid values for layer 2:
                  32,48,56,64,80,96,112,128,160,192,224,256,320,384

           -j            specifies use joint stereo mode IF the input
                         file contains stereo audio. This has no 
                         effect if audio is mono. 
                          (default non-joint stereo)

           -e            generate error protection bits (CRC)

           -c            set copyright bit

           -o            set original bit

           -d x          use de-emphasis 
                          where x = 0 for none
                                    1 for 50/15 microseconds
                                    2 for citt j.17

     inputfile.wav   A windows wav file constrained to the following
                     parameters:
                          Audio sample rate: 11.025, 22.05, and 44.1KHz
                          Audio sample size: 8 or 16 bit
                          Audio channels: 1 or 2
                          Uncompressed PCM audio only.

     outputfile.mp2  Optional, if not specified, inputfilename 
                     with .mp2 extension will be created.


Example:  wav2mp test

          This example will encode an .wav file "test.wav" located 
          in the current directory to test.mp2, at 128Kbit/sec 
          data rate.


QUALITY:
          PLEASE NOTE: although this encoder accepts wav files with
          less than 44.1KHz 16 bit audio, you aren't getting the 
          full value of MPEG compression in these cases. 
          Internally, the encoder simply upsamples the wav file 
          to 44.1Khz 16 bit. If your capturing the audio yourself,
          try doing it at the maximum rate/resolution of which 
          your equipment is capable.

Changes:
          Ver 1.0 - initial release.
          Ver 1.1 - added additional options (3-Feb-2001)

GUI:
          If you would like a GUI front-end for this program, a general
          use GUI is available from http://I.am/AzzaAzza69, together 
          with a suitable parameter file to invoke Wav2MP v1.1.
