game_chat_audio_format

Describes the format information needed to interpret Game Chat 2 audio data.

Syntax

typedef struct game_chat_audio_format {  
    uint32_t sample_rate;  
    uint32_t channel_mask;  
    uint16_t channel_count;  
    uint16_t bits_per_sample;  
    game_chat_sample_type sample_type;  
    bool is_interleaved;  
} game_chat_audio_format

Members

sample_rate  
Type: uint32_t

The sample frequency at which each channel should be played or recorded.

channel_mask  
Type: uint32_t

The channel mask with which to override the assignment of channels in a multichannel audio stream to speaker positions. For the bit-to-speaker mapping of this value, see the description of the dwChannelMask member for the WAVEFORMATEXTENSIBLE structure on Microsoft Docs. To use the default mapping, set this to 0.

channel_count  
Type: uint16_t

The number of channels of audio data.

bits_per_sample  
Type: uint16_t

The number of bits per sample. If this value is not byte-divisible, it is assumed that the containing sample type is padded with bits to make it byte-divisible.

sample_type  
Type: game_chat_sample_type

Specifies whether Game Chat 2 is using Pulse Code Manipulation (PCM) data represented by integers (game_chat_sample_type::integer) or floating-point numbers (game_chat_sample_type::ieee_float).

is_interleaved  
Type: bool

A flag representing whether the multichannel audio stream is interleaved for multi-channel formats.

Audio retrieved from Game Chat 2 is always marked as interleaved. This parameter has meaning only if game_chat_audio_format::channel_count is greater than 1.

Remarks

This structure is used to describe the format of audio data for pre-encode audio streams, post-decode audio source streams, and post-decode audio sink streams in Game Chat 2. The following functions get or set the game_chat_audio_format used by their corresponding stream objects:

For more information about audio formats, see Real-time audio manipulation.
