ZPlay::DetectFileBPM Method

Detect beat-per-minute value of specified file.

C++

int DetectFileBPM(System::String ^ FileName, TStreamFormat Format, TBPMDetectionMethod Method);

Parameters

Parameters	Description
System::String ^ FileName	String specifying file name.
TStreamFormat Format	Stream format identifier. Use sfAutodetect if you need to autodetect stream format of specified file.
TBPMDetectionMethod Method	Detection method. See valid detection methods.

Returns

BPM value. If algorithm can't detect BPM value, return value is 0.

Remarks

This function will open temporary stream and detect beat-per-minute. When detection process is done, stream will be closed.

Note: Detection process can take some time.

Warning: This function WILL NOT interfere with current playing.

BPM detection algorithm isn't 100 % accurate. Algorithm will stop when first valid BPM value is detected. If BPM value can't be detected, algorithm will try to search whole stream. If this fails, returned BPM value is 0.
