AfpAddTrackWav

The AfpAddTrackWav 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 AfpAddTrackWav task is based on acoustic landmark matching.

Parameters

Parameter Description Required
Type The task name. Set to AfpAddTrackWav. 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, HPE 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.  
SpecSize The analysis resolution.  
SugdInputChannels The channel layout of the input media file.  
SugdInputFrequency The sampling rate of the input media file.  
Tag The tag associated with the track being added. Yes
*If the database is defined in the HPE 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=AfpAddTrackWav&File=C:\Data\Jingle.wav&Tag=MyCompanyJingle&PackDir=C:\resources&Pack=Adverts

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