ZPlay.SetWaveOutFileW Method

Set wave output to disk file. (UNICODE version)

Pascal
function SetWaveOutFileW(const FileName: WideString; Format: TStreamFormat; fOutputToSoundcard: Boolean): Boolean; overload;
Parameters 
Description 
const FileName: WideString 
Points to string that specifies the name of the file. 
Format: TStreamFormat 
Specify encoding format. Library will encode PCM samples into this format using internal encoder. 
fOutputToSoundcard: Boolean 
Specify if you need to send PCM samples to soundcard output. If this value is true, library will play samples to soundcard output. 
Return Values 
Description 
All OK. 
Error. To get error message read here

By default, library will output decoded or recorded samples to soundcard. But you can intercept these PCM samples, encode samples to specified format and save encoded stream into disk file. 

Library decodes streams(mp3, ogg, ...) into raw PCM samples and sends these samples to soundcard. You can use callback mechanism to intercept these samples. 

SetWaveOutFile function is using the same approach. It intercepts raw PCM samples. Then sends these raw samples to specified encoder. Encoder produces output stream. And at the end, encoded stream is saved to specified disk file. 

Note:
Every opening function will cancel disk output and set output to soundcard. Therefore, you must set wave output to disk file after each opening function.
