BASS.NET API for the Un4seen BASS Audio LibraryWaveFormRenderStart Method (Boolean, BASSFlag, IntPtr, Int64)BASS.NET API for the Un4seen BASS Audio Library
Start the rendering process for audio data located at the memory position (peak levels will be scanned). Note: The FileName will be ignored.

Namespace: Un4seen.Bass.Misc
Assembly: Bass.Net (in Bass.Net.dll) Version: 2.4.12.0
Syntax

public bool RenderStart(
	bool background,
	BASSFlag flags,
	IntPtr memory,
	long length
)

Parameters

background
Type: SystemBoolean
, if rendering should be performed in an independent background thread (using a Normal priority). , if rendering should be executed synchronious.
flags
Type: Un4seen.BassBASSFlag
A combination of the BASSFlag flags on how to create the decoding stream. The BASS_STREAM_DECODE and BASS_STREAM_PRESCAN flags will be added automatically here, if not already set!
memory
Type: SystemIntPtr
Set to Zero to render from the file location given by FileName - else rendering will be performed
length
Type: SystemInt64
The length of the memory block (if specified).

Return Value

Type: Boolean
, if rendering was started successfully, else .
Remarks

This overload creates an internal decoding channel from the memory location given by memory allowing to render the peak levels independently.

If you intend to use this overload to render the wave form in parallel while already playing out the audio, it is recommended to specify the same flags as for your playing stream. This is because BASS_ChannelGetLength(Int32, BASSMode), BASS_ChannelGetPosition(Int32, BASSMode), BASS_ChannelSetPosition(Int32, Int64, BASSMode), BASS_ChannelBytes2Seconds(Int32, Int64) etc. would return different values if you specified different resolutions for your playing stream and your rendering stream (eg. a stream with BASS_SAMPLE_FLOAT would return twice as much bytes as a stream created with the default 16-bit resolution).

If your playing stream and this call uses different flags, you might use the SyncPlayback(Int32) method, so that the members Position2Frames(Int64), Frame2Bytes(Int32) or GetBytePositionFromX(Int32, Int32, Int32, Int32) will return converted values according to your playing stream.
