AUEDIT(1)AUEDIT(1)NAMEauedit - graphically record and edit audio files
SYNOPSISauedit [-audio servername] [-toolkitoption ...] [filename]
DESCRIPTIONauedit provides an X-based window-oriented interface allowing the user
to record and edit audio files. The editing features available
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.
AUEDIT AND THE ATHENA WIDGET SETauedit uses the X Toolkit Intrinsics and the Athena Widget Set. For
more information, see the Athena Widget Set documentation.
SCREEN LAYOUTauedit 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 con‐
tains multiple tracks, the tracks will be displayed in ascending
order. For stereo data, the convention is left track, then right
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
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.
PLAYING AN INTERVAL
To play an interval, click on the Play button (the one with the trian‐
gle on its side). The audio data delimited by the start and end mark‐
ers will be played. A dashed vertical line will indicate the approxi‐
mate 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.
THE FILE MENU
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
Save Saves the current file. A backup file will be cre‐
ated 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
Revert Discards all changes made since the last save and
restores the data to its state following the last
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.
THE EDIT MENU
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 frequen‐
cies, 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.
THE ZOOM MENU
In Zoom in by a factor of two.
Out Zoom out by a factor of two.
Markers Zoom in to the interval delimited by the start and
Full Zoom out to display all of the audio data.
THE EFFECTS MENU
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 with‐
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.
THE RECORD COMMAND
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
o A frequency field. This is the frequency of the recording in
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
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.
The following options may be used with auedit:
This option specifies the Network Audio System server to which
auedit should connect.
