6 auedit - graphically record and edit audio files

9 auedit [-audio servername] [-toolkitoption ...] [filename]
10
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 o Cutting, copying, pasting, and mixing within a single auedit in‐
17 stance or between multiple auedit instances.
18 o Changing the amplitude of an interval.
20 o Reversing an interval.
22 o Fading in or out an interval.
24
26 auedit uses the X Toolkit Intrinsics and the Athena Widget Set. For
27 more information, see the Athena Widget Set documentation.
28
30 auedit starts out with a single window divided into several areas:
31 o A collection of drop-down menus and command buttons.
33 o A volume indicator and control slider.
35 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 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 o Buttons to play, stop, and pause the audio.
46 o Two menus indicating the current file and data formats.
48 o Two editable fields containing the current frequency and the audio
50 file comment.
51
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
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
77 New... Initializes auedit with an empty file. You will be
78 prompted for the number of tracks for the new file.
79 Load... Loads a file. You will be prompted for the file
81 name.
82 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 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 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 Revert Discards all changes made since the last save and
99 restores the data to its state following the last
100 save.
101 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
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 Cut Moves the interval to the selection buffer.
121 Copy Copies the interval to the selection buffer.
123 Paste insert Inserts the selection buffer at the point marked by
125 the start marker.
126 Paste replace Replaces the data at the point marked by the start
128 marker with the data from the selection buffer.
129 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 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.
139
141 In Zoom in by a factor of two.
142 Out Zoom out by a factor of two.
144 Markers Zoom in to the interval delimited by the start and
146 end markers.
147 Full Zoom out to display all of the audio data.
149
151 All operations under the effects menu apply to the current interval.
152 Amplitude... Scale the amplitude. You will be prompted for the
154 scale. The scale may be non-integral.
155 Max Amplitude Scales the interval to its maximum amplitude with‐
157 out clipping.
158 Reverse Reverses the order of the data within the interval.
160 Fade In Linearly scales the interval using a scale ranging
162 from 0.0 to 1.0.
163 Fade Out Linearly scales the interval using a scale ranging
165 from 1.0 to 0.0.
166
168 Clicking on the Record button brings up the record dialog box. The
169 record dialog box consists of:
170 o A duration field. This is the maximum duration of the recording in
172 seconds.
173 o A frequency field. This is the frequency of the recording in
175 hertz.
176 o An input mode toggle button. Clicking this button toggles between
178 line mode and microphone mode.
179 o A gain slider. This controls the input gain level.
181 o A record toggle button. Clicking this button starts and stops the
183 recording.
184 o A monitor toggle button. Clicking this button toggles the record
186 monitoring feature that lets you hear what you're recording.
187 o A dismiss command button. Clicking this button stops any current
189 recording and dismisses the record dialog box.
190
192 The following options may be used with auedit:
193 -audio servername
195 This option specifies the Network Audio System server to which
196 auedit should connect.
197
199 nas(1), auconvert(1), X(1)
200
202 There is no way to manipulate individual tracks.
