#include <lc3/include/sw_codec_lc3.h>

Runs the LC3 encoder.

Parameters

[in]	pcm_data	Buffer containing PCM data
[in]	pcm_data_size	Number of bytes in pcm_data. Note that pcm_data is uint16_t *.
[in]	enc_bitrate	Bitrate of encoded mono stream (bps). If set to LC3_USE_BITRATE_FROM_INIT the bitrate given to sw_codec_lc3_enc_init() will be used. Consult the LC3 doc for legal values.
[in]	audio_ch	Index to which channel is being encoded
[in]	lc3_data_buf_size	Size of supplied LC3 buffer.
[out]	lc3_data	Pointer to LC3 data output buffer.
[out]	lc3_data_wr_size	Number of bytes written to lc3_data.

Note

The return codes from Zephyr and LC3 may overlap.

Returns

0 on success. -EPERM Encoder is not initialized. -EINVAL Too few PCM bytes given to encode. Other errors. Refer to LC3 documentation.
