ing the RECORD (7) button).
When in record mode, press the MENU (9) but-
ton to enter the Record Menu. This is where
all of the recording features can be viewed and
set. Use the jog scroll wheel to select a spe-
cific feature and press the ENTER (10) button
to view and/ or change a particular features
settings. Listed below are all of the features
contained in the Rec Menu.
FORMAT- Select the format feature to set the
type of file you wish to record. The HDR7 can
record files in WAV, MP3, AAC, and AIFF for-
mat (*Note- Once a recording has begun, these
settings are not able to be changed). These
formats are based on different file types that
produce recordings of differing memory size,
compatibility, and quality.
*Note: Slow USB storage devices may cause is-
sues when set to high bit rates.
Below is a brief comparison of the different
formats:
WAV- Waveform Audio Format
MP3- MPEG-1 Audio Layer 3
AAC- Advanced Audio Coding
AIFF- Audio Interchange File Format
SAMP. RATE- The sample rate represents the
number of samples per second taken from a
signal. As a sample rate goes up, so does qual-
ity, however the memory required increases as
well. For the HDR7, based upon which file for-
mat is selected, the following sample rates are
Conexiones y Control de sistema • Connexions & Utilisation • Anschlüsse und Systemeinstellungen
available: WAV & AIFF- 44.1 kHz / 48.0kHz/
88.2 kHz/ 96.0 kHz
*Recording Tip: Sampling rate affects the rate
at which the recorder samples the audio. As the
sampling rate increases, the length of the wave-
form increases, thus giving you better audio ac-
curacy, quality, and editing ability.
BIT DEPTH- Bit depth refers to how many bits
of sound are utilized within a particular sound
sample. As is true with sample rate, a higher bit
depth represents higher quality, however more
memory is required. The following bit depth
values are available for the corresponding file
formats: WAV & AIFF 16 bit, 24 bit
*Recording Tip: The importance of bit depth in re-
cording audio is that it determines the maximum
