===============================================================================USING wavrec and mpegrec===============================================================================For up to date usage information run the application with a --help parameter:$ mpegrec --helpmpegrec  Copyright (C) 2000 Andrew L.

USAGE: mpegrec [options]Options:        -b mp3_bitrate_in_kHz (for mpegrec only - default is 192)        -e encoder_process (for mpegrec only - default is "lame")        -l length_in_seconds  (default is to continue until ctrl-c)        -r rate               (default is 44100)        -o outputfilename     (default is stdout or "-")        -x extraEncoderFlags  (default is "")===============================================================================wavrec:===============================================================================wavrec simply captures audio at the rate specified with '-r rate' foreither the number of seconds specified with '-l seconds', or until Control-C ishit and sends the output to either 'STDOUT' or to the file specified with '-o outfile'.For example, to record 5 minutes of 22050 Hz audio into the file song.wav type:$ wavrec -l 300 -o song.wav -r 22050To capture the same audio and stream the contents to bladeenc you might do thefollowing:$ wavrec -l 300 -r 22050 | bladeenc - song.mp3In either case, hitting Control-C should stop the recording.  If you interruptthe recording with Control-C, the WAV header will have an inaccurate filelength and data block length, but most WAV players (and mp3 encoders) will nothave a problem with this.===============================================================================mpegrec:===============================================================================mpegrec is a sym-link to wavrec which when run automatically (or as somesay "automagically") pipes the WAV output to the 'lame' mp3 encoder.  Bydefault mpegrec requests STEREO (-ms) mp3 encoding at a bitrate of 192K.You can alter the bitrate using the '-b bitrate' parameters.  You can alsodirect mpegrec to use an alternate encoder by passing this information with the'-e lamereplacement' parms, and you can pass extra flags to lame or the '-ereplacement' with the -x parm.The simplest use is:$ mpegrec -l 300 -o song.mp3This records 5 minutes of audio at 44.1 KHz and instructs lame to encode it tothe file song.mp3 at a 192K bitrate.  For a lower quality file you might try:# mpegrec -l 300 -r 22050 -b 128 -o talk.mp3mpegrec does not do well when a rate over 44.1 Khz (-r 44100) is specified.You may have better luck with this than I.  I am running a dual Pentium II with64 MB or RAM, and a Creative Labs PCI 128 soundcard.  When specifying a rate of48000 sound quality is extremely poor.  It is excellent however at 44100 (CDQuality).Best Wishes.-Andrew L. Sandovalsandoval@netwaysglobal.comhttp://www.netwaysglobal.com
