15.2.4. Sound source file specifications and filenames
Notes
• All sound inputs are mixed and recorded.
• Noise may be generated, depending on the contents or volume settings of the input sound source. If annoying,
adjust the sound volume of the conference unit or external sound source.
Shown below are specifications and filename format for recorded sound source files:
• Specifications
Recording format: MP3 (monaural)
Sampling frequency: 32 kHz
Bit rate:
128 kbps
Maximum file size: 54.9 MB (recording time: 1 hour)
Tips
• Since the sound source file is automatically divided each time one hour elapses, the
above is the maximum size.
• The size of the internal memory is 1 GB, allowing recordings to be made for a total of
approximately 18 hrs.
• Filename format
A filename indicating the Year, Month, Date, Hour, Minute and Second of the time that the recording was
started is automatically assigned to each file as follows:
Sound source filename: YYYYMMDD_HHMMSS.mp3
Example
In the case of a recording started at precisely 10 o’clock AM on January 1, 2019,
the filename "20190101_100000.mp3" is assigned when the recording is stopped.
When a recording is continuously made for longer than one hour, the sound source file will automatically be
divided whenever one hour passes, and the resulting file saved under a newly assigned filename.
