Electric Echo Canceler
(EEC):
SP_EEC_CLIP_POS
Specifies the positive peak value at which the analog circuit
of the speaker saturates. Codec analog full scale
corresponds to μLAW full scale values after expansion. The
value of SP_EEC_CLIP_POS is set as shown for
SP_AEC_CLIP_POS, above.
Legal values: 0 to 32767.
16000
39
Electric Echo Canceler
(EEC):
SP_EEC_CLIP_NEG
Specifies the negative peak value at which the analog circuit
of the line-out saturates. Codec analog full scale corresponds
to μLAW full scale values after expansion. The value of
SP_EEC_CLIP_NEG is set as shown for SP_AEC_CLIP_POS,
above.
Legal values: –32768 to 0.
–16000
41
Electric Echo Canceler
(EEC):
SP_EEC_ENABLE
Enables/disables the electrical echo controller.
Legal values: 0 (disable), 1 (enable).
1
44
Electric Echo Canceler
(EEC):
SP_EEC_VOX_HYST
Controls the hysteresis in far-talker detection. (The
speakerphone state machine has a built-in hysteresis
mechanism to prevent fluctuations in the talker identification
process i.e., identifying the active side.) The value of this
parameter is a dimensionless number, which should be
evaluated during the tuning process for specific hardware.
Larger values for the parameter correspond to a wider
hysteresis loop. Negative values increase the probability that
the state machine remains in the last state.
Legal values: –127 to 127.
10
46
Electric Echo Canceler
(EEC):
SP_EEC_DTD_TH
Controls the sensitivity of the system. Low values correspond to
high sensitivity, with a greater false alarm probability (i.e., an
echo is considered a real talker).
High values correspond to low sensitivity, with slower switching.
This parameter is affected by the loop gain and the specific
hardware characteristics.
Legal values: 0 to 127.
82
33
Attenuation:
SP_BLOCK_LEVEL
Controls the maximum attenuation level of the speakerphone
suppressors. It affects the speakerphone stability and its
subjective quality. The maximum attenuation is calculated
according to:
SP_BLOCK_LEVEL/2
28
Legal values: 550 to 32000.
10922
42
Tone Generation:
SP_TONE_GEN_
LEVEL
Controls the energy level at which DTMF, and other tones, are
generated to the line (codec 0) while the speakerphone is
active. Each unit represents 3 dB.
Legal values: 0
≤
SP_TONE_GEN_LEVEL
≤
10.
Note: the energy level at which the tones are generated to
the speaker (codec 1) while the speakerphone is active, is
controlled by the TONE_GEN_LEVEL tunable parameter and
the vol_level.
