Functions
int	pscm_zero_pad (void const *const input, size_t input_size, enum audio_channel channel, uint8_t pcm_bit_depth, void *output, size_t *output_size)
	Adds a 0 after every sample from *input and writes it to *output.
int	pscm_copy_pad (void const *const input, size_t input_size, uint8_t pcm_bit_depth, void *output, size_t *output_size)
	Adds a copy of every sample from *input and writes it to both channels in *output.
int	pscm_combine (void const *const input_left, void const *const input_right, size_t input_size, uint8_t pcm_bit_depth, void *output, size_t *output_size)
	Combines two mono streams into one stereo stream.
int	pscm_one_channel_split (void const *const input, size_t input_size, enum audio_channel channel, uint8_t pcm_bit_depth, void *output, size_t *output_size)
	Removes every second sample from *input and writes it to *output.
int	pscm_two_channel_split (void const *const input, size_t input_size, uint8_t pcm_bit_depth, void *output_left, void *output_right, size_t *output_size)
	Splits a stereo stream to two separate mono streams.
