Filter Editor Protocol: Analog Measurement
Processing the Clarinet event file.
A filter can be applied either on-line at the end of the profile execution
with the configuration file set as WI_ANALOG by Clarinet-Init
or off-line using Filter=>Run Protocol on the main
menu.
Received voice
Definition of the monitored voice parameters and the
output file.
Codec: For selecting the default encoding specifications
of the samples in the Byte-TS or the RTP data flows.
Recognising a payload type for an RTP data flow automatically results
in the use of the relevant encoding specifications.
Jitter Buffer Size: In use only for RTP data
packets flow for reordering.
Output file: Parameters of the output file(s)
(.wav) to be automatically generated.
- File name: For editing the basename of the
wav file(s), which will be generated (or overwritten) in the working
directory.
The file will not be generated if the file name field is empty.
 access
to the list of the files located in the working directory.
The full name of the generated wav will include:-
- _Sxxxx with xxxx as the UDP source port number in
the case of an RTP flow, 0 otherwise.
- _Dxxxx with xxxx as the UDP destination port number
in the case of an RTP flow, 0 otherwise.
- _i with i as index of different issues.
Different indexes are used if both T and R directions and same '_Sx_Dx'.
- Codec: For selecting the encoding specifications
of the file.wav.
Quality Measurement
The flow of samples (RTP packets/Byte TS events) is processed according
to the following rules:-
- No "reference file": basic QoS events are
systematically generated (each RTP packets/Byte TS events)
- one valid file name is specified in the "reference file"
area: the processing starts (Basic QoS events are generated) only
while the heading sequence of samples included in the reference file
is detected in the flow of samples.
- Synchro is selected, the processing starts only while the
sequence of samples included in the "synchro" pattern is detected in the flow
of samples.
Definition of the type and parameters of the voice QoS
measurement.
Mode: How the QoS measurement events are generated
Synchro
Reference file: Name of the reference file:
- File name: For editing the name of the wav
file, located in the working directory.
access
to the choice list of the files located in the working directory.
- Codec: For selecting the encoding specifications
of the wav file.
Automatically set by default to the actual encoding type of the selected
file.
PSQM: Perceptual Speech Quality Measurement according
to ITU-P861.
 No:
PSQM is not used. Yes:
PSQM measurement events are generated. Requires a reference file.
PESQ: Perceptual Evaluation of Speech Quality according
to ITU-P862.
- No:
PESQ is not used.
- Yes:
PESQ measurement events generated. Needs a reference file.
Delay between Meas: Duration for cyclic generation
of the Average result events.
Reset values:-
- No:
Values of the Average result events are not reset at every cycle.
- Yes:
Values of the Average result events are reset at every cycle.
