6.4 Recording an Audio File
1. Enter a file name for the audio file you are about to record. The RECORD button will be
grayed out and will not work until you have entered a filename.
2. The default file name for the Normalized Audio file will be your file name with
“_NORMALIZED” appended. You may change this file name by overwriting the file name
in the text box.
3. The default folder for Recorded Audio files and Normalized Audio files is the Music
folder on your Windows PC. If you wish to change the location of the recordings, press
the “…” button to the right of the filename fields and select the directory you would like
to use.
4. Press the RECORD button once to start recording and again to stop the recording.
5. The status section of the screen will indicate whether the system is recording. Talk
clearly into the microphone and view the Monitor level on the Microphone Controls
section of the interface.
6. If the monitor indicates “Clip”, then this means that you are speaking too loudly into the
mic, or you are holding the mic too close. Recordings with clipped audio cannot be
corrected by this software and may cause damage to the Acoustic Driver in the LRAD.
Press the RECORD button again to stop the recording. You may make adjustments to
the mic position or your speaking volume and reinitiate the recording by pressing the
RECORD button. If you have not changed the filename, you will be prompted to
overwrite the existing recording.
7. If you are creating a recording in a noisy environment and you have to speak loudly into
the mic to overcome background noise, lower the Mic Level slider until you can record
at a Monitor level that does not produce clipping.
8. Once a recording has been created, a Normalized Audio file will be automatically
created and saved in the specified file location.
9. You may listen to the original recording by pressing the PLAY button to the left of the
Recorded Audio File Name text box. Audio will be played back through your PC’s
speakers or headphones.
10. You may listen to the optimized recording by pressing the PLAY button to the left of the
Normalized Output File Name text box. Audio will be played back through your PC’s
speakers or headphones.
