Parameter

Description

nPlayer

Number representing the zero-based index of the player that owns the sound composer session

strFriendlyName

Friendly name of the item

nChannel

Mono channel or stereo channel pair of the audio stream that will reproduce the item.

This parameter is ignored when the sound file is added in "append mode" after a previous call to the SoundComposer.ItemAppendNext method.

Due to the fact that the audio stream previously created through the SoundComposer.SessionCreate method could be multi-channel, this would be the behaviour when a sound file item is added:

(*) If for example the audio stream previously created through the SoundComposer.SessionCreate method should have 8 channels (7.1 multi-channel), stereo channels pairs would be mapped as follows:

- stereo channel pair 0 would group mono channels 0 and 1

- stereo channel pair 1 would group mono channels 2 and 3

- stereo channel pair 2 would group mono channels 4 and 5

- stereo channel pair 3 would group mono channels 6 and 7

strPathname

Absolute pathname of the raw sound file

nEncodeMode

Encode mode used to encode the RAW file.

Supported values are the following:

bIsBigEndian

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

Supported values are the following:

nFrequency

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

nChannels

Number of channels of the RAW file: for example, 1 for Mono or 2 for Stereo, 6 for 5.1 formats and so on

bDownMixToMono

Boolean flag specifying if there is the need of a downmix in order to store a stereo sound file into a mono channel of the stream.

Supported values are the following:

This parameter is ignored when the sound file is added in "append mode" after a previous call to the SoundComposer.ItemAppendNext method.

nOffsetMs

Offset of the item, expressed in milliseconds, respect to the beginning of the audio stream (in case the stream should be in stopped state) or respect to the current playback position (in case the stream should be already in playback state).

This parameter is ignored when the sound file is added in "append mode" after a previous call to the SoundComposer.ItemAppendNext method.

nStartPositionMs

The start position, expressed in milliseconds, where the sound file loading will occur. Set this value to 0 for loading from the beginning of the sound.

nEndPositionMs

The end position, expressed in milliseconds, where the sound file loading will occur. Set this value to -1 for loading till the sound end.

nUniqueId

Reference to a value that, on return from the method call, will contain the unique identifier of the newly added element: this unique identifier will be used in order to invoke further methods related to the use of this specific element:

- SoundComposer.ItemFriendlyNameGet to obtain the friendly name of the item

- SoundComposer.ItemFriendlyNameSet to obtain the friendly name of the item

- SoundComposer.ItemContentGet to obtain contents of the item

- SoundComposer.ItemInfoGet to obtain various information about the item

- SoundComposer.ItemAmplitudeSet to modify the amplitude of the item

- SoundComposer.ItemChannelSet to modify the channel of of the audio stream that will reproduce the item

- SoundComposer.ItemRemove to remove the item from the sound composition

- SoundComposer.ItemOffsetSet to modify the offset, expressed in milliseconds, of the item respect to the beginning of the audio stream

- SoundComposer.ItemTypeGet to obtain the item's type

Value

Meaning

Negative value

An error occurred (see the LastError property for further error details)

enumErrorCodes.NOERROR (0)

The method call was successful.
