C++ (Cpp) DataChunk::getFormat Examples

Example #1

File: Compressor.cpp Project: ReDetection/sound-processor

void Compressor::apply(DataChunk& samples){
    switch( samples.getFormat()->bitsPerSample()/8){
        case 2:
            maxint =32767;break;
        case 1:
            maxint = 127;
            break;
    }
    b = (1.0-a2)*maxint;
    DiskreteEffect::apply(samples);
}

Example #2

File: DiskreteEffect.cpp Project: ReDetection/sound-processor

void DiskreteEffect::apply(DataChunk &samples){
    unsigned short bytePerSample=samples.getFormat()->bitsPerSample()/8;
    unsigned int count=samples.getSize()/bytePerSample; //samples count
    char *data8 = samples.getData();

    switch (bytePerSample) {
        case 1:

        case 2:

            for(unsigned int i=0;i<count;i++)
