Nucleus Name
DS_SYS_AudioLoop
Nucleus Number
1216
Description
In this nucleus the Codec generates an audio sine signal with a specific
signature and sends it to the output of the digital board. The Codec encodes
the audio signal to MPEG I layer II and after this the signature of the signal will
be checked.
Note
: Before executing this nucleus the user must route the audio signal on
the VIP using
DS_VIP_Routing
.
Technical
-
The user needs to route the signal to the audio inputs so the test can
encode the audio to MPEG I layer II
-
An audio signal is generated, resulting in a sine of 6kHz on the left and
12kHz on the right channel.
-
Then the signal is decoded in memory.
-
When both signals are detected correctly in the MPEG, the test succeeded.
Execution Time
Approximately 9 seconds
User Input
InputType:
-
I2S (default, when no user input is given)
-
SPDIF: This input needs a second parameter:
- OPT (optical,
default
, when no user input is given)
- COAX

121602
No audio could be generated.
121603
The audio encoder did not encode audio.
121604
