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:

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

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

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

                          -j         specifies use joint stereo mode IF
                                     input file contains stereo audio.
                                     Has no effect if audio portion of .avi
                                     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 = 1 for none
                                                               2 for 50/15 microseconds
                                                               3 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 .mpg
                            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 your equipment is capable of.

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