| Methods |
| void Flush() | Completes processing of the last available data. Recommended to call before component closing |
| bool FormatChoose(BSTR Title, long Handle) | Creates an ACM-defined dialog box that enables the user to select a waveform-audio format. Title parameter indicates dialog's title, Handle - parent handle of dialog window. If Handle is 0 then ActiveX component handle is used |
| VARIANT GetData() | Reads available data from output stream. Usually used when OnDataAvailable event fires |
| long GetVolume(long Channel) | Returns current volume value. CalcVolume must be set to True. Pass Channel = 0/1 (left/right) for stereo and 0 for mono. Result values range is 0...300 (logarithmic scale) |
| void SetData(VARIANT* data) | Writes data to input stream |
| bool SetVolume(long Channel, long Volume) | If Channel has default value of -1, this volume value will be applied on all channels. Volume = 1000 means no volume change (100%); 500 = 50%; 2000 = 200% and so on |
| Properties |
| bool Active | Set to true to activate (open) the component. All other properties should be set to proper values before activation. Set to false to deactivate (close) the component |
| bool AddSilence | Specifies whether device should add silence when it runs out of audio data |
| bool AutoActivate | When true tells the component it must activate consumer (if any) before activating itself. Same applies for deactivation. When false the component does not change the consumer state |
| bool CalcVolume | When true tells the component to calculate the audio volume of a stream coming into or from the component |
| long DataSizeIn | Returns data written into but not yet processed by the pipe |
| long DataSizeOut | Returns data size available to read from the pipe |
| long DstPcmBitsPerSample | Specifies number of bits per sample for destination PCM format of resampler device |
| long DstPcmNumChannels | Specifies number of channels per sample for destination PCM format of resampler device |
| long DstPcmSamplesPerSec | Specifies number of sampler per second for destination PCM format of resampler device |
| BSTR DumpInput | File name to dump the component input data to |
| BSTR DumpOutput | File name to dump the component output data to |
| bool IsFormatProvider | When true the component will assign stream format to the consumer (if any). This simplifies the process of distributing stream format among linked components. For example WaveRiff component can assign PCM format to linked WaveOutDevice component, so WAVe file will be played back correctly |
| long OverNum | Specifies how many chunks of data component can store in input or output buffer, if data cannot be processed immediately. Every chunk holds 1/10 sec. of audio. Set this property to 0 to disable the buffer overflow checking (NOTE: be carefully, since this could lead to uncontrolled memory usage grow) |
| long PcmBitsPerSample | Specifies number of bits per sample for wave device |
| long PcmNumChannels | Specifies number of channels per sample for wave device |
| long PcmSamplesPerSec | Specifies number of samples per second for wave device |
| bool RealTime | Specifies whether device is working as real-time device |
| unaSilenceDetectionMode SilenceDetectionMode | No silence detection - unasdm_none. Obsolete approach - unasdm_VC. New approach based on dynamic speech processing - unasdm_DSP. |
| bool SyncEvents | Specifies whether events calls synchronized through main thread |
