3.4.4.Insertion Profiles

Overview

Insertion “profiles” are optional modifiers that are applied to an entire temporary insert, whether a discrete file or a playlist. This is invoked only by in-channel Compel commands. A field in the insertion command may specify a profile. Zero (‘0’) is the normal default in Compel commands and means “use no profile”. But a value between 1 and 255 requires a user-specified profile be used, if found. Remember that the effects of the profiles last only as long as the applicable insert, and have no meaning after the end of the file/playlist insert (or any meaning after said insert is aborted). The profiles themselves are defined in special files that reside in the i6420’s /u/user/.sysconfig/profiles directory. The files are named n.def where ‘n’ is the profile number code, between 1 and 255 inclusive. Any kind of profile design may be assigned any number, though it is advised that all i6420s in a network use the same profile number code for the same profile design.

The profile files themselves are simple text files of the form:

return { key_1 = value_1 , key_2 = value_2, … } where key_1 is one of the possible keywords, and value_1 is a value selection for that keyword, and so on. Note that a profile file may contain any or all of the legal keywords. But if a keyword appears twice in a profile file, or there are other spelling or format errors, the profile will not be used when the Compel insertion command is received. It is best that implementers “try out” their profiles first, in a controlled environment, to be sure that the desired behavior results.

Current Profile Keywords

preSilence: This forces the start of the file/playlist insert to be delayed by the value given, with audio silence inserted between the end of live and the delayed position of the insert. Values are in mS, 0 to 5000.

postSilence: This forces the resumption of the live audio, after the file/playlist insert ends, to be delayed by the value given, with audio silence inserted. Values are in mS, 0 to 5000.

ducking: This allows the live permanent audio to continue to mix with the file/playlist insert at the audio output, during the entire time of the insert. The value specifies the amount of attenuation, from normal level, experienced by the live audio while mixing “into” the insert. This value is in dB, and may be specified down to tenths of a dB (e.g. ‘6.2’ for 6.2 dB).

atten: This attenuates the file/playlist audio during the insert. The value specifies the amount of attenuation. This value is in dB, and may be specified down to tenths of a dB.
