[Gambas-user] Generating a sine wave with ALSA

[Ru Vuott]

Uhmmmm... it would seem to be correct.
In fact, if I insert this line in the code C:

   printf("SND_PCM_FORMAT_FLOAT value =  %d", SND_PCM_FORMAT_FLOAT);

and then I run that compilated C code, I obtain in terminal this results:

     SND_PCM_FORMAT_FLOAT value =  14


In addition, you can easily calculate the enumeration of that ALSA Constant in this page (see at Enumerations):

  http://www.alsa-project.org/alsa-doc/alsa-lib/group___p_c_m.html

You can see:  SND_PCM_FORMAT_FLOAT = SND_PCM_FORMAT_FLOAT_LE


Thank you for your  help.

bye
vuott

 At least this isn't right:
 Private Const SND_PCM_FORMAT_FLOAT As Integer = 14
 
 I'll look more closely later.

 Rapidly troubleshoot problems before they affect your
 business. Most IT 
 organizations don't have a clear picture of how application
 performance 
 affects their revenue. With AppDynamics, you get 100%
 visibility into your 
 Java,.NET, & PHP application. Start your 15-day FREE
