Detailed Description

This helps to extract/insert a subset of channels from/to the payload, and convert it to floating-point format.

Member Function Documentation

Configure()

bool sound4::CAudioConverter::Configure ( SampleFormat  fmt, size_t  nFrame, size_t  payl_ch, size_t  payl_ch_offset, ConverterTargetMode  target_mode  )

inline

Configure the converter.

The floating-point channels count depends on target_mode. It can be the same as payload, or fixed to mono or stereo.

Parameters

fmt	the format of the payload
nFrame	the number of frames per packet
payl_ch	the number of channels in the payload
payl_ch_offset	the offset of the first channel to extract/insert in the payload [must be <= (payload_channels-output_channels)]
target_mode	defines the number of channels in process, and the number of channels to extract from payload for mono<->stereo conversion

Returns

true if was created

Note

The converter is not multithread-safe, it uses internal cache buffers.

Definition at line 1620 of file sound4cl.hpp.

ConvertFrom()

void sound4::CAudioConverter::ConvertFrom ( const uint8_t *  payload, float *  output  )

inline

Convert the payload to floating-point array, using a predefined converter.

Warning

Output buffer must be 64-byte aligned

Parameters

payload	the binary raw audio buffer
output	audio output buffer (64 byte aligned)

Definition at line 1644 of file sound4cl.hpp.

ConvertTo()

void sound4::CAudioConverter::ConvertTo ( const float *  input, uint8_t *  payload  )

inline

Convert floating-point array to payload, using a predefined converter.

Warning

Input buffer must be 64-byte aligned

Parameters

input	audio input buffer (64 byte aligned)
payload	the binary raw audio buffer

Definition at line 1655 of file sound4cl.hpp.

Delete()

void sound4::CAudioConverter::Delete ( )

inline

Definition at line 1627 of file sound4cl.hpp.

IsOK()

bool sound4::CAudioConverter::IsOK ( ) const
