auedit - graphically record and edit audio files

auedit  uses  the  X  Toolkit Intrinsics and the Athena Widget Set.  For more information, see the Athena
       Widget Set documentation.

auedit  provides  an  X-based window-oriented interface allowing the user to record and edit audio files.
       The editing features available include:

       o   Cutting, copying, pasting, and mixing within a single auedit  instance  or  between  multiple  auedit
           instances.

       o   Changing the amplitude of an interval.

       o   Reversing an interval.

       o   Fading in or out an interval.

       Many functions in auedit operate on a range of audio data  called  an  interval.   The  initial  interval
       encompasses all of the audio data.  The interval is indicated within the wave form by two solid, vertical
       lines.   The  left marker indicates the start of the interval.  The right marker indicates the end of the
       interval.  To select an interval of audio data, use the mouse to move the interval markers  in  the  wave
       form.   Pressing  a  mouse  button in the wave form will select the marker closest to the mouse position.
       That marker may then be dragged to the desired location in the wave form.  Note that the markers may  not
       cross over each other.

       auedit - graphically record and edit audio files

       The following options may be used with auedit:

       -audioservername
               This option specifies the Network Audio System server to which auedit should connect.

       To  play  an  interval, click on the Play button (the one with the triangle on its side).  The audio data
       delimited by the start and end markers will  be  played.   A  dashed  vertical  line  will  indicate  the
       approximate  position of the data currently being played.  To stop playing, click on the Stop button (the
       one containing a solid square).  Clicking on Pause (the button containing two vertical,  parallel  lines)
       will  pause  the  playing.  To resume, click on Pause again.  The volume slider controls the play volume.
       The interval is played at the frequency specified by the Frequency field.  Note that while data is  being
       played, most other functions are disabled.

auedit starts out with a single window divided into several areas:

       o   A collection of drop-down menus and command buttons.

       o   A volume indicator and control slider.

       o   The audio file represented as a wave form.  If the audio data contains multiple  tracks,  the  tracks
           will  be  displayed  in  ascending  order.  For stereo data, the convention is left track, then right
           track.

       o   A set of indicators displaying the interval start, duration, and end and the current position.  These
           indicators are in units of minutes, seconds, and hundredths of seconds.

       o   Buttons to play, stop, and pause the audio.

       o   Two menus indicating the current file and data formats.

       o   Two editable fields containing the current frequency and the audio file comment.

       The cut, copy, and paste commands in the edit menu transfer data to and from a  selection  buffer.   This
       buffer  is  shared  between  all  instances of auedit.  This means that you can cut or copy data from one
       instance of auedit and paste it into another instance.  The only restriction is that the  audio  data  in
       both  instances  must  have  the  same  number  of  tracks.   When transferring data between instances of
       differing frequencies, the data will be converted to the frequency of the destination.  This can be  used
       to  change the frequency of the data in a single instance of auedit.  First, cut the data whose frequency
       you wish to change.  Then change the Frequency field to the desired frequency.  Finally, paste  the  data
       back in.  The frequency of the data will be converted to the frequency specified in the Frequency field.

       Cut                 Moves the interval to the selection buffer.

       Copy                Copies the interval to the selection buffer.

       Paste insert        Inserts the selection buffer at the point marked by the start marker.

       Paste replace       Replaces  the  data  at  the  point marked by the start marker with the data from the
                           selection buffer.

       Paste mix           Mixes the data at the point marked by  the  start  marker  with  the  data  from  the
                           selection buffer.  The mixing function is an average.

       Undo                Undoes  the  last  operation  that  modified  the  audio data.  This includes effects
                           operations in addition to editing operations.  If the last operation was an Undo then
                           the undo is undone, restoring the data to the state prior to the first undo.

       All operations under the effects menu apply to the current interval.

       Amplitude...        Scale the amplitude.  You will be prompted for the scale.   The  scale  may  be  non-
                           integral.

       Max Amplitude       Scales the interval to its maximum amplitude without clipping.

       Reverse             Reverses the order of the data within the interval.

       Fade In             Linearly scales the interval using a scale ranging from 0.0 to 1.0.

       Fade Out            Linearly scales the interval using a scale ranging from 1.0 to 0.0.

       New...              Initializes auedit with an empty file.  You will be prompted for the number of tracks
                           for the new file.

       Load...             Loads a file.  You will be prompted for the file name.

       Save                Saves  the  current  file.  A backup file will be created by appending a tilde (~) to
                           the current file name.  The file format, data format, frequency and comment are  used
                           when saving the file.

       Save as...          Saves  the  current  file  under a new name.  You will be prompted for the file name.
                           The file format, data format, frequency and comment are used when saving the file.

       Save interval...    Saves the interval to a file.  You will be  prompted  for  a  file  name.   The  file
                           format, data format, frequency and comment are used when saving the file.

       Revert              Discards  all  changes  made  since  the last save and restores the data to its state
                           following the last save.

       Exit                Exits auedit.  If there have been changes made to the current file that have not been
                           saved, you will be asked if you wish to save them.

       Clicking on the Record button brings up the record dialog box.  The record dialog box consists of:

       o   A duration field.  This is the maximum duration of the recording in seconds.

       o   A frequency field.  This is the frequency of the recording in hertz.

       o   An input mode toggle button.  Clicking this button toggles between line mode and microphone mode.

       o   A gain slider.  This controls the input gain level.

       o   A record toggle button.  Clicking this button starts and stops the recording.

       o   A  monitor  toggle  button.  Clicking this button toggles the record monitoring feature that lets you
           hear what you're recording.

       o   A dismiss command button.  Clicking this button stops any current recording and dismisses the  record
           dialog box.
