Hi,
Please try to fine tune below parameters and see if any improvement. thanks.
GAMMA_NN float 3 0 rw Over-subtraction factor of non- stationary noise. min … max attenuation
GAMMA_NN_SR float 3 0 rw Over-subtraction factor of non-stationary noise for ASR.
[0.0 … 3.0] (default: 1.1)
GAMMA_NS float 3 0 rw Over-subtraction factor of stationary noise. min … max attenuation
GAMMA_NS_SR float 3 0 rw Over-subtraction factor of stationary noise for ASR.
MIN_NN float 1 0 rw Gain-floor for non-stationary noise suppression.
[−inf … 0] dB (default: −10dB = 20log10(0.3))
MIN_NN_SR float 1 0 rw Gain-floor for non-stationary noise suppression for ASR.
[−inf … 0] dB (default: −10dB = 20log10(0.3))
MIN_NS float 1 0 rw Gain-floor for stationary noise suppression.
[−inf … 0] dB (default: −16dB = 20log10(0.15))
MIN_NS_SR float 1 0 rw Gain-floor for stationary noise suppression for ASR.
[−inf … 0] dB (default: −16dB = 20log10(0.15))
