Dear support team,

 

Mute module(with SW RC type Slew) occasionally outputs wrong data.

 

Could you tell me cause and measures,please?

 

Symptom:

Please check attatched file (wrong_data.PNG, wrong_data2.PNG,nomal_data.PNG).

Test project file is also attatched.(Mute_clip_dspproj)

 

This issue is shown in every about 100~200 times in this project.

(The waves of normal_data.PNG is almost observed.)

 

Though I do not understand of why,

when IIR filter( low frequency band pass filter) is placed in before mute module,

The incidence increases.

 

Environment:

Sigma Stadio 3.4

EVAL-ADAU170XEBZ

 

Best regards,

Takehiro Yabune
