Typedefs
typedef void(*	le_audio_receive_cb) (struct net_buf *audio_frame, struct audio_metadata *meta, uint8_t location_index)
	Callback for receiving Bluetooth LE Audio data.

Functions
int	le_audio_concurrent_sync_num_get (uint8_t *num_streams, enum bt_audio_location *locations)
	Get the number of active streams.
int	le_audio_metadata_populate (struct audio_metadata *meta, const struct bt_bap_stream *stream, const struct bt_iso_recv_info *info, const struct net_buf *audio_frame)
	Function to populate the audio metadata.
int	le_audio_ep_state_get (struct bt_bap_ep const *const ep, uint8_t *state)
	Get the current state of an endpoint.
bool	le_audio_ep_state_check (struct bt_bap_ep const *const ep, enum bt_bap_ep_state state)
	Check if an endpoint is in the given state. If the endpoint is NULL, it is not in the given state, and this function returns false.
bool	le_audio_ep_qos_configured (struct bt_bap_ep const *const ep)
	Check if an endpoint has had the QoS configured. If the endpoint is NULL, it is not in the state, and this function returns false.
int	le_audio_freq_hz_get (const struct bt_audio_codec_cfg *codec, int *freq_hz)
	Decode the audio sampling frequency in the codec configuration.
int	le_audio_duration_us_get (const struct bt_audio_codec_cfg *codec, int *frame_dur_us)
	Decode the audio frame duration in us in the codec configuration.
int	le_audio_octets_per_frame_get (const struct bt_audio_codec_cfg *codec, uint32_t *octets_per_sdu)
	Decode the number of octets per frame in the codec configuration.
int	le_audio_frame_blocks_per_sdu_get (const struct bt_audio_codec_cfg *codec, uint32_t *frame_blks_per_sdu)
	Decode the number of frame blocks per SDU in the codec configuration.
int	le_audio_bitrate_get (const struct bt_audio_codec_cfg *const codec, uint32_t *bitrate)
	Get the bitrate for the codec configuration.
int	le_audio_stream_dir_get (struct bt_bap_stream const *const stream)
	Get the direction of the stream provided.
bool	le_audio_bitrate_check (const struct bt_audio_codec_cfg *codec)
	Check that the bitrate is within the supported range.
bool	le_audio_freq_check (const struct bt_audio_codec_cfg *codec)
	Check that the sample rate is supported.
void	le_audio_print_codec (const struct bt_audio_codec_cfg *codec, enum bt_audio_dir dir)
	Print the codec configuration.
int	le_audio_print_qos_from_stream (struct bt_bap_stream const *const stream)
	Print the QoS configuration for a stream.
int	le_audio_print_unicast_group (struct bt_cap_unicast_group const *const unicast_group)
	Print the unicast group information.
