Input Area
 Level: This audio meter displays the input audio levels coming in via the chosen
audio interface device.
 Source: This pop-up menu lets you choose a connected Mac OS X–compatible audio
device to record your audio. For example, if you’re using a microphone connected to
an audio interface, you choose the audio interface here.
 Offset: This pop-up menu allows you to correct for audio signal latency (delay),
which is inherent in all digital audio interfaces. Even though your voiceover
performance may be perfect, latency can cause the recorded audio to be slightly
offset from the video. Different digital audio capture devices have different amounts
of latency. Typically, most USB capture devices have a latency of one frame; most
DV camcorders have a latency of three frames.
 Input: If the audio input device you’re using has multiple inputs, this pop-up menu
lets you choose which one you use to record. If there are multiple audio devices you
can use, Final Cut Express remembers the input you choose for each device, if you
change devices.
 Rate: This pop-up menu lets you choose an audio sample rate supported by the
audio device selected to record your voiceover clips. It’s best to use the same audio
sample rate used in your sequence. If the selected audio device cannot support your
sequence’s sample rate, choose the next closest available sample rate. For example, if
your sequence is set to 48 kHz but your audio device doesn’t support that sample
rate, choose 44.1 kHz.
 Gain: This slider allows you to adjust the recording level used by the Voice Over tool.
Note: Audio input selections made in the Voice Over tool do not affect your selected
capture preset.
