             Summary: Bad sound quality when up sampling from SLIN16 to SLIN32
                 Key: ASTERISK-28511
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-28511
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Formats/format_sln
    Affects Versions: 13.28.0
            Reporter: Ruddy G


When asterisk receive a SIP call in SLIN16 codec and have to convert it to SLIN32, there is a degradation of sound quality at the places where we have voice saturation.

There is a sign inversion which creates a bad voice quality.

The same issue is present when converting a SLIN16 to SLIN32 format from the CLI interface.
