AfptAddTrackStream

DEPRECATED:

The AfptAddTrackStream task is deprecated in IDOL Speech Server version 11.5 and later. Use the AfpAddTrack task instead.

This task is still available for existing implementations, but it might be incompatible with new functionality. The task might be deleted in future.

The AfptAddTrackStream task allows you to add a new audio track to the audio fingerprint database, receiving the audio data as a stream and converting it into AFP features before indexing. If the database does not already exist, it is created by adding the track.

The AfptAddTrackStream task uses templates as opposed to landmarks, which improves robustness to audio mismatches at the cost of scaleability.

For more information about connecting to an audio stream, see the IDOL Speech Server Administration Guide.

Parameters

Parameter Description Required
Type The task name. Set to AfptAddTrackStream. Yes
AfpDb The audio fingerprint database (if it is defined in the configuration file). *
Pack The audio fingerprint database (if it is not defined in the configuration file). *
PackDir

The path to the directory containing the database.

If this directory does not already exist, manually create it before sending the action. If the database does not yet exist, IDOL Speech Server creates the database in this directory.

*
Rnd A window size within which a random offset shift is calculated.  
Sfreq The sample frequency of the audio file to process.  
Tag The tag associated with the track being added. Yes
NOTE:

The database type for this template-based audio fingerprinting task is fptdb (as opposed to fpdb for landmark-based audio fingerprinting).

If the database is defined in the IDOL Speech Server configuration file, you must set the AfpDb parameter. If the database is not defined, set both the Pack and PackDir parameters instead.

Example

http://localhost:13000/action=AddTask&Type=AfptAddTrackStream&Tag=MyCompanyJingle&PackDir=C:\resources&Pack=Adverts

This action uses port 13000 to instruct IDOL Speech Server, which is located on the local machine, to use template-based matching to index the streamed audio into the Adverts database. If the Adverts database does not already exist, IDOL Speech Server creates it. If the clip is subsequently identified in an audio file, IDOL Speech Server identifies it using the tag MyCompanyJingle.
