By that I mean, how do I tell Delphi using DSPack that the output wav file should be 16 bit, 44100Hz, 2Ch/Stereo? Thanks, SA Back to top Tsviatko Jongov Guest Posted: Fri Aug 04, 2006 8:12 am    Post subject: Re: WAVE file settings Hi, By setting the Default Sound Capture filter settings to 16 bit, 44100 Hz, stereo. After this filter you must connect WAVDest filter, which will add WAV header data to the stream and FileWriter, which will write your wave file.

Hoi Tsviatko Good answer, but unfortunately MK will not see it, because you posted on Google Groups, that means your answer is invisible to MK and most other people that reads these groups. You need to repost it on the Borland news server.

Just to make it clear I've got 2 filters, FileSource and FileWriter which connect to each other. What I need to do is add a third filter called WAVDEST and in it's properties (viewed by double clicking the filter) set the output type (16 bit, 44.1khz, stereo). Then I make the FileSource filter connect to WAVDEST and WAVDEST to FileWriter, is this correct?

Now I see that you want to convert existing wave file to 44.1 KHz, 16 bps, stereo wave file. If that is correct, you'll need an audio resampler filter. I don't know if there are any free resampling filters, so you must write your own. WaveDest filter takes care only for the wave file header and doesn't tuch the audio data.

I've got the resampling filter written/coded and I can even output it to wav but the only problem I had was sometimes the wav file produced would be in mono and sometimes in stereo. That's why I wanted to know if there was a way to guarantee the output is always in stereo.

The Format filed must be WAVFormatEx structure and the nChannels will give you if the output wave file will be mono or stereo. If it is mono you can write a transform filter which will convert mono data to stereo (you can add silence in the new channel or double the existing channel). You can also embed this code in your resampler filter. Regards, Tsviatko Jongov "MK" <mk_astrotel (AT) hotmail (DOT) com> wrote: Quote: Hi, thanks for the reply!
