6 years ago The frontend delivers bits (soft bits). In the data-bakend resp audio-backend the selected vectors of soft bits are made into hard bits (vector size 24 bitrate). These backend functions themselves pass on the bitvectors (again, size 24 bitrate) to appropriate handlers.
The soundhandlers, MP2 and MP4 then pack the bits since the processing elements in these functions expect vectors filled with bytes, The data handlers, on the other hand, - selected in the class dataProcessor
- maintain the vectors of bits and each of the implemented (or partly implemented) handlers will - or will not - make them into bytes.
Key is that the audio resp. databackend convert the incoming softbits into 24 * bitrate sized vectors of hardbits.

Firstly, congratulations on such a great project!!
I have a small query re function addtoFrame(uint8_t* outV) which is present in both the audio and data processors.e.g. mp2Processor::addtoFrame()
My understanding is that the input array to this function is in the form of unpacked bits, these are then packed into bytes in the first few lines of both mp2Processor::addtoFrame() and mp4Processor::addtoFrame()
However, on the corresponding data version, i.e. dataProcessor::addtoFrame(outV), no unpacking seems to be present, but the function itself seems to be working on byte arrays rather than on unpacked bits
Am I missing something, or is the unpacking done somewhere else?
Thanks for your time ed
