Methods > Append and mixing automation > MixAutomationItemAddFromFileRaw method

Remarks

Adds a sound file in RAW format, or a portion of the sound file, taken from a given pathname to the mixing automation list.

For further information about management of append automation sessions refer to the How to mix or append several sounds in one single shot tutorial.

Parameter

Description

strPathname

String representing the absolute pathname of the source sound file.

nEncodeMode

Encode mode used to encode the RAW file.

Supported values are the following:

Mnemonic constant	Value	Meaning
RAW_ENCODE_PCM_U8	0	RAW PCM 8 bits Unsigned
RAW_ENCODE_PCM_S8	1	RAW PCM 8 bits Signed
RAW_ENCODE_PCM_S16	2	RAW PCM 16 bits Signed
RAW_ENCODE_PCM_S24	3	RAW PCM 24 bits Signed
RAW_ENCODE_PCM_S32	4	RAW PCM 32 bits Signed
RAW_ENCODE_FLOAT32	5	RAW 32 bits floating point
RAW_ENCODE_G711_ULAW	6	RAW G711 U-LAW
RAW_ENCODE_G711_ALAW	7	RAW G711 A-LAW
RAW_ENCODE_GSM_610	8	RAW GSM 6.10
RAW_ENCODE_DIALOGIC_VOX	9	RAW Dialogic ADPCM VOX

bIsBigEndian

Boolean flag that specifies if bits order inside the RAW file are little-endian or big-endian

Supported values are the following:

Value	Meaning
false	The RAW file is encoded using little-endian
true	The RAW file is encoded using big-endian

nFrequency

Sample rate of the RAW file (e.g. 44100)

nChannels

Number of channels of the RAW file: 1 for Mono or 2 for Stereo

nStartPosition

Start position, expressed in milliseconds, of the range to load from the added sound file

nEndPosition

End position, expressed in milliseconds, of the range to load from the added sound file

fVolume

Volume level applied to the added song when it will be appended.

Supported values are expressed with a linear volume in the range from 0 to 100. In case you should need to set a volume expressed in dB, before setting this parameter you could convert the value in dB into a linear value through the following formula (C syntax):

VolumeLinear = 100 * pow (10, VolumeInDB/20);

nMixPosition

Position, expressed in milliseconds, inside the destination sound where the added file will be mixed

Return value

Value	Meaning

Negative value	An error occurred. Check the LastError property value in order to see the last error.
enumErrorCodes.ERR_NOERROR (0)	The method call was successful.
