-------------------------------------------

             Summary: Siren14 does not translate from/to slin32
                 Key: ASTERISK-20695
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-20695
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Codecs/codec_siren14
    Affects Versions: 11.0.1
         Environment: Ubuntu 12.04 x86_64 running Linux 3.2.0 and Asterisk 11.0.1 stable release
            Reporter: Mathis Schmieder


The closed source siren14 codec offers no translator from and to slin32, only slin16 and slin. In order to sample the 14kHz bandwidth of siren14, a sample rate of at least 28kHz is needed. If it is wanted to record a siren14 channel in a raw audio format, a translator between siren14 and slin32 is needed.
As there is no openly available en/decoder for the siren14 codec, the possibility to record in another superwideband codec like slin32 would be highly useful, especially in cases where the full bandwidth of siren14 is needed.
