Public Methods
| Name | Description | |
|---|---|---|
 | BufferFrameChannelsAppend | Appends audio channels from buffer to a specified frame, the number of samples retrieved from specified frame |
| BufferFrameFill | Reads audio from buffer to a frame. If _nSamples = 0 then the audio duration calculated from frame rate, if _nSamples < 0 then whole buffer is used. |
| BufferFrameMix | Mixes audio from buffer with specified frame, the number of samples retrieved from specified frame. Note: The audio can be insufficient. In this case use two lines for mixing. |
| BufferFramePut | Puts audio from a frame to the buffer. |
| BufferGet | Get audio data from buffer. For planar format specify _cbAudioPlane: -1 auto size (from number of samples), 0 - interleaved. Note: if _ppAudio is NULL then allocate internal buffer, else copy to specified buffer. |
| BufferLinesMix | Mixes audio from buffer lines |
| BufferLinesRemove | Removes line from buffer |
| BufferLoadFromFile | Loads audio form file to a buffer. |
| BufferPropsGet | Gets buffer's audio props |
| BufferPropsSet | Sets buffer's audio properties |
| BufferPutPtr | Puts audio data to a buffer. If _pbAudio is NULL then the buffer is filled with silence |
| BufferPutPtrEx | Put audio data to buffer, also correct audio data by time (add silence or skip data), for planar format specify _cbAudioPlane: -1 auto size (from number of samples), 0 - interleaved |
| BufferRemove | Removes audio data from the buffer |
| BufferTimesEnable | Enable audio buffer times watching (e.g. for BufferFramePut, BufferFrameFill methods) and set max difference for times (if 0 then ONLY breaks are used) |
| BufferTimesGet | Get audio buffer times (if any) |
| BufferTimesIsEnabled | Indicates whether buffer times are enabled and shows differences values |
| BufferTimesSet | Set audio buffer start/end time (remove or add audio if needed) Note: The rtEndTime ONLY for minimum time, if buffer end is greater then ignored. |
