AcmFormatEnumFlags

enum NAudio.Wave.Compression.AcmFormatEnumFlags

Format Enumeration Flags.

Enumerator
None	None.
Convert	ACM_FORMATENUMF_CONVERT The WAVEFORMATEX structure pointed to by the pwfx member of the ACMFORMATDETAILS structure is valid. The enumerator will only enumerate destination formats that can be converted from the given pwfx format.
Hardware	ACM_FORMATENUMF_HARDWARE The enumerator should only enumerate formats that are supported as native input or output formats on one or more of the installed waveform-audio devices. This flag provides a way for an application to choose only formats native to an installed waveform-audio device. This flag must be used with one or both of the ACM_FORMATENUMF_INPUT and ACM_FORMATENUMF_OUTPUT flags. Specifying both ACM_FORMATENUMF_INPUT and ACM_FORMATENUMF_OUTPUT will enumerate only formats that can be opened for input or output. This is true regardless of whether this flag is specified.
Input	ACM_FORMATENUMF_INPUT Enumerator should enumerate only formats that are supported for input (recording).
Channels	ACM_FORMATENUMF_NCHANNELS The nChannels member of the WAVEFORMATEX structure pointed to by the pwfx member of the ACMFORMATDETAILS structure is valid. The enumerator will enumerate only a format that conforms to this attribute.
SamplesPerSecond	ACM_FORMATENUMF_NSAMPLESPERSEC The nSamplesPerSec member of the WAVEFORMATEX structure pointed to by the pwfx member of the ACMFORMATDETAILS structure is valid. The enumerator will enumerate only a format that conforms to this attribute.
Output	ACM_FORMATENUMF_OUTPUT Enumerator should enumerate only formats that are supported for output (playback).
Suggest	ACM_FORMATENUMF_SUGGEST The WAVEFORMATEX structure pointed to by the pwfx member of the ACMFORMATDETAILS structure is valid. The enumerator will enumerate all suggested destination formats for the given pwfx format. This mechanism can be used instead of the acmFormatSuggest function to allow an application to choose the best suggested format for conversion. The dwFormatIndex member will always be set to zero on return.
BitsPerSample	ACM_FORMATENUMF_WBITSPERSAMPLE The wBitsPerSample member of the WAVEFORMATEX structure pointed to by the pwfx member of the ACMFORMATDETAILS structure is valid. The enumerator will enumerate only a format that conforms to this attribute.
FormatTag	ACM_FORMATENUMF_WFORMATTAG The wFormatTag member of the WAVEFORMATEX structure pointed to by the pwfx member of the ACMFORMATDETAILS structure is valid. The enumerator will enumerate only a format that conforms to this attribute. The dwFormatTag member of the ACMFORMATDETAILS structure must be equal to the wFormatTag member.

AcmFormatSuggestFlags

enum NAudio.Wave.Compression.AcmFormatSuggestFlags

Enumerator
FormatTag	ACM_FORMATSUGGESTF_WFORMATTAG.
Channels	ACM_FORMATSUGGESTF_NCHANNELS.
SamplesPerSecond	ACM_FORMATSUGGESTF_NSAMPLESPERSEC.
BitsPerSample	ACM_FORMATSUGGESTF_WBITSPERSAMPLE.
TypeMask	ACM_FORMATSUGGESTF_TYPEMASK.

AcmStreamHeaderStatusFlags

enum NAudio.Wave.Compression.AcmStreamHeaderStatusFlags

Enumerator
Done	ACMSTREAMHEADER_STATUSF_DONE.
Prepared	ACMSTREAMHEADER_STATUSF_PREPARED.
InQueue	ACMSTREAMHEADER_STATUSF_INQUEUE.

AcmStreamOpenFlags

enum NAudio.Wave.Compression.AcmStreamOpenFlags

Enumerator
Query	ACM_STREAMOPENF_QUERY, ACM will be queried to determine whether it supports the given conversion. A conversion stream will not be opened, and no handle will be returned in the phas parameter.
Async	ACM_STREAMOPENF_ASYNC, Stream conversion should be performed asynchronously. If this flag is specified, the application can use a callback function to be notified when the conversion stream is opened and closed and after each buffer is converted. In addition to using a callback function, an application can examine the fdwStatus member of the ACMSTREAMHEADER structure for the ACMSTREAMHEADER_STATUSF_DONE flag.
NonRealTime	ACM_STREAMOPENF_NONREALTIME, ACM will not consider time constraints when converting the data. By default, the driver will attempt to convert the data in real time. For some formats, specifying this flag might improve the audio quality or other characteristics.
CallbackTypeMask	CALLBACK_TYPEMASK, callback type mask.
CallbackNull	CALLBACK_NULL, no callback.
CallbackWindow	CALLBACK_WINDOW, dwCallback is a HWND.
CallbackTask	CALLBACK_TASK, dwCallback is a HTASK.
CallbackFunction	CALLBACK_FUNCTION, dwCallback is a FARPROC.
CallbackThread	CALLBACK_THREAD, thread ID replaces 16 bit task.
CallbackEvent	CALLBACK_EVENT, dwCallback is an EVENT Handle.

AcmStreamSizeFlags

enum NAudio.Wave.Compression.AcmStreamSizeFlags

Enumerator
Source	ACM_STREAMSIZEF_SOURCE.
Destination	ACM_STREAMSIZEF_DESTINATION.
