Functions

sac_word_size_t sac_get_word_size_from_bit_depth(sac_bit_depth_t bit_depth)

Get the number of bytes used to store a sample of a given bit depth.

Parameters:

bit_depth – [in] Sample bit depth.

Returns:

Word size.

uint16_t sac_get_nb_packets_in_x_ms(uint16_t ms, uint16_t audio_payload_size, uint8_t nb_channel, sac_bit_depth_t sample_bit_depth, uint32_t sampling_rate)

Get the number of audio packets in a given amount of milliseconds.

Parameters:

  • ms – [in] The number of milliseconds.

  • audio_payload_size – [in] The size of the audio payload in bytes.

  • nb_channel – [in] The number of audio channels.

  • sample_bit_depth – [in] The bit depth of the samples in the audio payload.

  • sampling_rate – [in] The sampling rate of the samples in the audio payload in Hz.

Returns:

Number of audio packets, rounded down.
