7

SYNOPSIS

9       auedit [-audio servername] [-toolkitoption ...] [filename]
10

DESCRIPTION

12       auedit  provides an X-based window-oriented interface allowing the user
13       to record and edit audio files.  The  editing  features  available  in‐
14       clude:
15
16       o   Cutting,  copying,  pasting,  and mixing within a single auedit in‐
17           stance or between multiple auedit instances.
18
19       o   Changing the amplitude of an interval.
20
21       o   Reversing an interval.
22
23       o   Fading in or out an interval.
24

AUEDIT AND THE ATHENA WIDGET SET

26       auedit uses the X Toolkit Intrinsics and the Athena  Widget  Set.   For
27       more information, see the Athena Widget Set documentation.
28

SCREEN LAYOUT

30       auedit starts out with a single window divided into several areas:
31
32       o   A collection of drop-down menus and command buttons.
33
34       o   A volume indicator and control slider.
35
36       o   The  audio file represented as a wave form.  If the audio data con‐
37           tains multiple tracks, the tracks will be  displayed  in  ascending
38           order.   For  stereo data, the convention is left track, then right
39           track.
40
41       o   A set of indicators displaying the interval  start,  duration,  and
42           end  and  the  current  position.  These indicators are in units of
43           minutes, seconds, and hundredths of seconds.
44
45       o   Buttons to play, stop, and pause the audio.
46
47       o   Two menus indicating the current file and data formats.
48
49       o   Two editable fields containing the current frequency and the  audio
50           file comment.
51

INTERVALS

53       Many functions in auedit operate on a range of audio data called an in‐
54       terval.  The initial interval encompasses all of the audio  data.   The
55       interval  is  indicated  within  the  wave  form by two solid, vertical
56       lines.  The left marker indicates the start of the interval.  The right
57       marker indicates the end of the interval.  To select an interval of au‐
58       dio data, use the mouse to move the interval markers in the wave  form.
59       Pressing a mouse button in the wave form will select the marker closest
60       to the mouse position.  That marker may then be dragged to the  desired
61       location  in  the  wave form.  Note that the markers may not cross over
62       each other.
63

PLAYING AN INTERVAL

65       To play an interval, click on the Play button (the one with the  trian‐
66       gle  on its side).  The audio data delimited by the start and end mark‐
67       ers will be played.  A dashed vertical line will indicate the  approxi‐
68       mate  position  of  the  data currently being played.  To stop playing,
69       click on the Stop button (the one containing a solid square).  Clicking
70       on  Pause  (the  button  containing  two vertical, parallel lines) will
71       pause the playing.  To resume, click on Pause again.  The volume slider
72       controls  the  play  volume.   The  interval is played at the frequency
73       specified by the Frequency  field.   Note  that  while  data  is  being
74       played, most other functions are disabled.
75

THE FILE MENU

77       New...              Initializes auedit with an empty file.  You will be
78                           prompted for the number of tracks for the new file.
79
80       Load...             Loads a file.  You will be prompted  for  the  file
81                           name.
82
83       Save                Saves the current file.  A backup file will be cre‐
84                           ated by appending a tilde (~) to the  current  file
85                           name.   The file format, data format, frequency and
86                           comment are used when saving the file.
87
88       Save as...          Saves the current file under a new name.  You  will
89                           be  prompted  for  the file name.  The file format,
90                           data format, frequency and comment  are  used  when
91                           saving the file.
92
93       Save interval...    Saves the interval to a file.  You will be prompted
94                           for a file name.  The  file  format,  data  format,
95                           frequency  and  comment  are  used  when saving the
96                           file.
97
98       Revert              Discards all changes made since the last  save  and
99                           restores  the  data to its state following the last
100                           save.
101
102       Exit                Exits auedit.  If there have been changes  made  to
103                           the current file that have not been saved, you will
104                           be asked if you wish to save them.
105

THE EDIT MENU

107       The cut, copy, and paste commands in the edit menu transfer data to and
108       from  a  selection buffer.  This buffer is shared between all instances
109       of auedit.  This means that you can cut or copy data from one  instance
110       of  auedit and paste it into another instance.  The only restriction is
111       that the audio data in both instances must  have  the  same  number  of
112       tracks.  When transferring data between instances of differing frequen‐
113       cies, the data will be converted to the frequency of  the  destination.
114       This  can  be  used to change the frequency of the data in a single in‐
115       stance of auedit.  First, cut the data  whose  frequency  you  wish  to
116       change.  Then change the Frequency field to the desired frequency.  Fi‐
117       nally, paste the data back in.  The frequency of the data will be  con‐
118       verted to the frequency specified in the Frequency field.
119
120       Cut                 Moves the interval to the selection buffer.
121
122       Copy                Copies the interval to the selection buffer.
123
124       Paste insert        Inserts the selection buffer at the point marked by
125                           the start marker.
126
127       Paste replace       Replaces the data at the point marked by the  start
128                           marker with the data from the selection buffer.
129
130       Paste mix           Mixes  the  data  at  the point marked by the start
131                           marker with the data  from  the  selection  buffer.
132                           The mixing function is an average.
133
134       Undo                Undoes  the  last operation that modified the audio
135                           data.  This includes effects operations in addition
136                           to  editing  operations.  If the last operation was
137                           an Undo then the undo is undone, restoring the data
138                           to the state prior to the first undo.

153       Amplitude...        Scale the amplitude.  You will be prompted for  the
154                           scale.  The scale may be non-integral.
155
156       Max Amplitude       Scales  the interval to its maximum amplitude with‐
157                           out clipping.
158
159       Reverse             Reverses the order of the data within the interval.
160

162                           from 0.0 to 1.0.
163
164       Fade Out            Linearly  scales the interval using a scale ranging
165                           from 1.0 to 0.0.
