[asterisk-bugs] [JIRA] (ASTERISK-20695) Siren14 does not translate from/to slin32

[Mathis Schmieder (JIRA)]

     [ https://issues.asterisk.org/jira/browse/ASTERISK-20695?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Mathis Schmieder updated ASTERISK-20695:
----------------------------------------

    Description: 
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 for the Linux OS, 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.
