Syntax
[Visual Basic] Public Function InitHostInfo ( strAcrCloudHost as String, strAccessKey as String, strAccessSecret as String, nSnippetStartSec as Int32, nSnippetStopSec as Int32 ) as enumErrorCodes |
[C#] public enumErrorCodes InitHostInfo ( string strAcrCloudHost, string strAccessKey, string strAccessSecret, int nSnippetStartSec, int nSnippetStopSec ); |
[C++] public: enumErrorCodes InitHostInfo ( string strAcrCloudHost, string strAccessKey, string strAccessSecret, int nSnippetStartSec, int nSnippetStopSec ); |
Parameter |
Description |
|

strAcrCloudHost |
String containing the URL of the host issued by AcrCloud for connecting to their services |
strAccessKey |
String containing the access key issued by AcrCloud for connecting to their services |
strAccessSecret |
String containing the secret key issued by AcrCloud for connecting to their services |
nSnippetStartSec |
Start position, expressed in seconds, within the sound file where recognition begins; when the recognition is started through the SoundRecognizer.StartOnWasapiDevice method, this value should be set to 0 because recognition starts immediately by capturing sound incoming from the selected WASAPI device |
nSnippetStopSec |
End position, expressed in seconds, within the sound file where recognition ends; when the recognition is started through the SoundRecognizer.StartOnWasapiDevice method, this value represents the duration in seconds of the sound snippet to analyze; usually a value between 3 and 5 should be enough for most commercial music around |
