Record Properties contains all of the recording related settings and features. Use these to monitor the recording sources, start recording automatically when a sound is detected (level activated), delay recording until a certain time (timer), and more.
Recording Settings | |
---|---|
Setting | Description |
Use new file duration | Sets the duration for recording a new sound. See Entering Times. If this box is unchecked, then a window appears when you choose the Record New button so that the duration may be entered. If the box is checked, the duration given here is used for all new recordings and no window appears. |
Dictation mode |
Allows you to quickly switch between recording and playback (Punch In/Out). The playback marker
is moved to the recording marker whenever recording is stopped. Recording starts at the playback marker instead
of the start marker. Use this feature to record dictation and rewind (or reposition the playback marker) and re-record
to fix mistakes. Use the Record Dictation button to
resume recording. This button replaces the Record Selection button.
This setting overrides the Recording Mode to use Unbounded recording and disables loop recording. New audio is recorded over the existing audio, replacing it. Note that recording is stopped without warning when playback is started. Do not use this mode for live recordings that should not be interrupted. |
Monitor input on visuals | Connects the recording source to the
visuals so you can adjust volume levels before recording.
Monitoring works only when the current sounds's sampling rate is
compatible with the recording device or no sounds are opened.
See Recording Sounds for information about selecting a different recording source and setting volumes. |
Ctrl key safety | Prevents you from accidentally recording over a sound. To record, you must hold down the Ctrl key, otherwise a safety message appears. |
Set finish marker at stop | Automatically moves the finish marker to the place where recording stopped. This makes it easier to trim the file after recording. |
Show settings window | Displays an information window whenever recording is started. The window gives the current recording setup, including the recording device, the selected inputs, and other settings. Click on a label link to change the setup. Recording may be stopped when the setup is changed. |
Filter dc offset | Automatically filters a dc offset from the audio during recording. Use this setting if you see a lot of activity on the low frequency bars and VU meters even when recording silence. |
Auto save | Automatically saves the file when recording ends.
Bounded recording mode must be selected.
If recording is manually
stopped, the file is not automatically saved. Use this setting with
the Timer setting to save
a recording after a scheduled event.
If you start recording in a new, untitled file, you will be prompted to provide a filename so that it can be saved under that name automatically. The default save format is used for the file type and attributes. If you start recording in an existing file, the original file will be overwritten when recording ends and recording cannot be undone. |
Record Mode | |
---|---|
Setting | Description |
Bounded to selection | Records within the selection only. Recording stops automatically at the end of the selection. If you stop recording before the end is reached, the rest of the selection is replaced with silence. Use this setting to record for a fixed length of time. |
Bounded and looped | The is similar to the above setting, but recording restarts automatically when the end is reached and continues to record over and over until the Stop button is pressed. This is useful if you are trying to capture a sound but do not know when it might occur. By loop recording a 1 minute sound, you will always have the last minute of audio stored for recall. |
Unbounded | Recording starts at the start marker's position and continues recording until all storage is exhausted or until you press the Record Stop button. The file size is increased automatically to hold the new audio. This is useful if you do not know how long the recording will be. |
Delayed Recording
Timer
delays recording until the specified time and day of
the week. Use this feature to automatically record something at
a later time. The time is given in 24 hour time. A time of 06:00:00 is
6:00 AM and a time of 18:00:00 is 6:00 PM. 00:30:00 is 12:30 AM or
30 minutes past midnight. When entering the time, remember
to include the seconds. Entering 18:00 means 00:18:00.
You must press the Record button to activate the timer.
Remember to press the Record button to activate delayed recording (timer or level activated).
Turn off any power management settings that may power down the computer.
Level activated automatically synchronizing recording to a sound source or efficiently captures airport or police radio communications containing mostly silence that does not need to be recorded. It starts recording automatically when the sound source is above a given level and pauses recording when the sound is below the level.
Level Activated Settings | |
---|---|
Setting | Description |
Threshold | Specifies how loud a sound should be before recording begins. The value must be high enough so that noise does not trigger recording and low enough so that other sounds will. Start with a value around -20dB or record some background silence for several minutes to get a baseline and use Maximize Volume (Normalize) effect to get the peak level and set the threshold value above that. Be sure to keep the device recording volume the same. Any changes to that volume will affect the threshold (other Windows program may change the recording volume). |
Minimum duration | Specifies how long to record after the sound becomes quiet again. Using a value of 3 allows recording to continue for three seconds after the sound goes below the specified threshold. To minimize silence, use a value of 1 second or less, but not zero. A zero value causes recording to continue without stopping once triggered. |
Prebuffer | Specifies the amount of audio to store prior to activation. When activation occurs, the prebuffer audio is inserted before the currently recorded audio, allowing you to hear the sound slightly before activation. |
Time stamp cues | Marks the date, time, and position of each recording activation with a cue point. Use the Cue Points tool to view and edit cue points. Use the edit box to specify the format for the date (this is done using the C strftime function). Some format specifiers are given in the next table and examples in the following table. |
