The AfptMatchWav
task is deprecated in IDOL Speech Server version 11.5 and later. Use the AfpMatch 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 AfptMatchWav
task searches an audio file for any sections that match audio indexed in an AFP database.
The AfptMatchWav
task uses templates as opposed to landmarks, which improves robustness to audio mismatches at the cost of scaleability.
Parameter | Description | Required |
---|---|---|
Type | The task name. Set to AfptMatchWav . |
Yes |
AfpDb | The audio fingerprint database (if it is defined in the configuration file). | See Comments |
Delay | The delay in updating results. | |
DelDelay | The amount of time (in terms of audio processed) between the last valid template hit being detected in a match, and that match being deleted. | |
File | The audio file to search. | Yes |
MinDuration | The minimum duration of a section that must match before that match is considered. | |
MinHits | The minimum number of hits that a section of audio must generate before IDOL Speech Server returns it as a match for a clip in an audio fingerprinting database. | |
MinRate | The minimum hit rate threshold for audio fingerprint identification. | |
MinScoreAvg | A threshold applied on the average template hit score, below which a candidate result is rejected. | |
MinScoreRate | A threshold applied to the average template hit score, divided by the length of the section matched. | |
NBest | The maximum number of matching AFP clips to include in the results for a section. | |
Out | The file to write the results to. | Yes |
Pack | The audio fingerprint database (if it is not defined in the configuration file). | See Comments |
PackDir |
The path to the directory containing the database. |
See Comments |
Rnd | A window size within which a random offset shift is calculated. | |
Sfreq | The sample frequency of the audio file to process. | |
TimeQ | The degree of quantization to perform. |
The database type for this template-based audio fingerprinting task is fptdb
(as opposed to fpdb
for landmark-based audio fingerprinting).
http://localhost:15000/action=AddTask&Type=AfptMatchWav&File=C:\Data\July18.wav&Pack=Adverts&PackDir=C:\resources&Out=July18Results.ctm
This action uses template-based matching to search the July18.wav
file for sections that match audio indexed in the Adverts
database and writes the search results to the July18Results.ctm
file.
