- Description
The TDx_SoundBuffer::SetFrequency method will define the playing frequency, in Hertz, of audio samples for a secondary sound buffer.
The minimum and maximum frequencies are defined in the dsound.h DSBFREQUENCY_MIN and DSBFREQUENCY_MAX members as 100 and 100,000 respectively.
Changing frequency modifies the pitch of audio data, not the format.
If the method call fails, the OnError event will be triggered with one of the following values:
TDX_BADPARAMS
DSERR_CONTROLUNAVAIL
DSERR_GENERIC
DSERR_INVALIDPARAM
DSERR_PRIOLEVELNEEDED
- Parameters
Frequency
The Frequency parameter defines the frequency, in hertz, at which audio samples are to be played by the buffer.
DSBFREQUENCY_ORIGINAL may be used to restore the original frequency defined in the format used when creating the buffer.
