AUDIO EDITOR: CHAPTER ONE 353
Customizing Audio Editor
You can customize the way you work in Audio Editor using the Preferences
dialog box, opened by clicking File: Preferences [
F
6] or by double-clicking
on the Status bar. Here, you can control the display of the waveform, the
time format used, and assign a mixer program for recording audio files.
PREFERENCES DIALOG BOX
1. X-Axis unit [Time Format] specifies the unit of time for each edit window.
Selecting the Time (M:S.ms) option displays audio file information in minutes,
seconds and milliseconds. The SMPTE (M:S:Frame) option shows the time in
minutes, seconds and frames. This is especially helpful if you are editing audio
for use in Video Editor as it allows you to match the audio portions with each frame
of a video sequence. You can choose between film (24 fps), PAL (25 fps) and
NTSC (30 fps), or, for irregular frame rates define your own, such as 15, for
example. For detailed editing of audio select the Samples option; this displays
time in samples per second. For example, if your sampling rate is 11.025 kHz,
then the waveform shows 11,025 sample points per second.
2. Waveform display controls the detail with which Audio Editor draws waveforms.
Selecting the Precise scan option produces a very detailed waveform, but may
take more time to redraw because of the extra information. The Quick scan
option produces a slightly less accurate waveform but is much quicker at
redrawing. In most cases the Quick scan option is more than adequate for editing
at the seconds level. If you want to go to the sample level, then select the
Precise scan.
3. Move cursor when playing moves the cursor along the waveform whenever you
play audio files. If you are low on memory, clear this option as it requires extra
resources.
