AfptAddTrackWav

The AfptAddTrackWav task allows you to add a new audio track to an audio fingerprint database, reading the data from an audio file and converting it into AFP features before indexing. If the database does not already exist, it is created by adding the track.

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

Parameters

Parameter Description Required
Type The task name. Set to AfptAddTrackWav. Yes
AfpDb The audio fingerprint database (if it is defined in the configuration file). *
File The name of the audio file to index. Yes
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 template-based audio fingerprinting 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=AfptAddTrackWav&File=C:\Data\Jingle.wav&Tag=MyCompanyJingle&PackDir=C:\resources&Pack=Adverts

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