Hi,<br>
I have a few questions concerning the WaveOut... function available for VC++ that are cannot be found in the libraries.<br>
<br>
1. Is there any delay from the time I invoke waveOutWrite, and send the audio to the device, to the time the sound device plays the sound out of the speakers.<br>
<br>
2. Is there a minimum buffer size for the audio buffer that is sent to the device, in order to play it proper, or is that a specification with <br>
in the sound device.<br>
<br>
I am asking these questions because currently, I am creating a basic voice conference software for a project and I need to find out these technical<br>
details to eliminate some latency problems. I would like to know what happens to the audio buffer in memory once it is sent to the device for playback.<br>
<br>
- Is the entire buffer locked in memory while device is playing it? Or is <br>
a set number of bytes of memory in the vicinity of the data the sound is <br>
currently playing that gets locked?<br>
<br>
- I am not sure if these properties are set within the win32 API or with <br>
the sound device themselves but if you can shed some light on some of the <br>
questions I have, answers or sources of information that can possible <br>
lead to the answers, I would greatly appreciate it. <br>
<br>
Thanks,<br>
