Recording Format (Sp/Lpm); Voice-Activated Recording - Philips DPM 9220 User Manual

Recording format (SP/LPm)

The recording format determines the recording speed and audio quality of the recorded sound files.
: Standard Play recording format.
: Long Play mobile recording format.
The default setting is SP. For more information on changing this setting, refer to the corresponding section in the
DPM menu section in this manual.
Note: Only one format can be selected for each file; the format for a file can be changed as long as no recording
has been done in the file.
After recording has been done in the file, it is possible to switch between the SP and LPm recording format in the
DPM menu. This change will not take effect for the current file but from the next new file onwards. From that point
on, any new files are recorded in the selected format until the setting is changed again.
The values for the two formats are as follows:
Standard Play (SP) 13.7 kbit/s
With this format, about 312 minutes of recording time are available. This recording format provides excellent
audio quality. It is recommended when the dictation sound files are used, for example, for speech recognition.
Long Play mobile (LPm) 9.1 kbit/s
This recording format provides good audio quality. With this format, about 468 minutes of recording time are
available.

Voice-activated recording

Voice-activated recording mode is a convenient feature for hands-free dictation. When voice-activated recording
is enabled, the DPM is in Record Standby mode; recording will start automatically when the input level exceeds a
certain threshold (i.e. usually when you start dictating). This means that recording stops a few seconds after you
stop speaking and restarts automatically when you start speaking again.
To operate the DPM in voice-activated recording mode, do the following:
1. Enable voice-activated recording in the DPM menu. For more information, refer to the corresponding
DPM menu section in this manual.
2. Press the REC (Record) button; the device is in Record Standby mode.
3. Start dictating and recording will start automatically. The symbol for voice-activated recording is shown on the
DPM display.
When you stop dictating, the DPM goes back into Record Standby after two seconds.
