		uint8_t	num_channels
	)

#include <lc3/include/sw_codec_lc3.h>

Initializes the LC3 decoder and allocates required RAM.

Parameters

[in]	pcm_sample_rate	Sample rate in Hz (typ. 16000 or 48000)
[in]	pcm_bit_depth	Output PCM bits per sample.
[in]	framesize_us	Frame size in microseconds
[in]	num_channels	Number of channels to initialize

Note

The return codes from Zephyr and LC3 may overlap.

Returns

0 on success. -EALREADY if already initialized. Other errors. Refer to LC3 documentation.
