The red book (RECMP3) application was written to record the audio from an external source (dynamically defined by the "-external" argument) to an mp3 file.When finished recording, a mp3 file is written to a temporary directory.You can select the filename from a menu before the recording starts.RECMP3 supported conversion to the following file formats:-Wav (variable bitrate)-Wav (fixed bitrate)-Mpg (variable bitrate)-Mpg (fixed bitrate)-Mpg (variable bitrate)-Mpg (fixed bitrate)-Mpg (variable bitrate)-Mpg (fixed bitrate)-MP4 (variable bitrate)-MP4 (fixed bitrate)-MP3 (variable bitrate)-MP3 (fixed bitrate)-MP3 (variable bitrate)-MP3 (fixed bitrate)-MP3 (variable bitrate)-MP3 (fixed bitrate)-M4A (variable bitrate)-M4A (fixed bitrate)-M4A (variable bitrate)-M4A (fixed bitrate)-Wav (variable bitrate)-Wav (fixed bitrate)-Wav (variable bitrate)-Wav (fixed bitrate)-Wav (variable bitrate)-Wav (fixed bitrate)-Wav (variable bitrate)-Wav (fixed bitrate)-Wav (variable bitrate)-Wav (fixed bitrate)-Wav (variable bitrate)-Wav (fixed bitrate)-Wav (variable bitrate)-Wav (fixed bitrate)-Wav (variable bitrate)-Wav (fixed bitrate)-M4A (variable bitrate)-M4A (fixed bitrate)-M4A (variable bitrate)-M4A (fixed bitrate)-M4A (variable bitrate)-M4A (fixed bitrate)-M4A (variable bitrate)-M4A (fixed bitrate)-M4A (variable bitrate)-M4A (fixed bitrate)-M4A 08929e5ed8
