Hi all,

Could anyone tell me how to determine/calculate the playtime for a wav file in c / c++ ?

TIA,
Freddy

for short files you can spawn wave to play the wav file and catch sigchld

u probably can compute the play time in seconds as ((FileSize-HeadersSize)/BitsPerSample)/SampleRate

Hi,

Thanks for answering. But shouldn’t the playtime be:

Data_Size / ByteRate instead of:

((FileSize-HeadersSize)/BitsPerSample)/SampleRate

Cheers,
