Witam.
Rozgryzam ten problem już n-tą godzinkę. Mianowicie mam problem z odtworzeniem w czasie rzeczywistym strumienia z mikrofonu.
W programie pokolei mam:
BASS_Init(-1, 44100, 0, hwnd, NULL);
BASS_RecordInit(-1);
hRecord = BASS_RecordStart(44100, 2, 0, RecordProc, NULL);
BASS_ChannelPlay(hRecord, true);
oraz:
BOOL CALLBACK RecordProc(HRECORD handle, const void *bufer, DWORD length, void *user)
{
return TRUE;
}
Macie może jakies wskazowki? Korzystam z dikumentacji: http://www.un4seen.com/doc/#bass/BASS_RecordStart.html

EDIT !!!!
Udało mi się siebie posłuchać, lecz niestety są straszne szumy. Może ktoś spojrzeć na ten kod?
