soxr重采樣的使用，使用自帶example里的例子soxoneshot,一維處理，實(shí)現(xiàn)變速。input是解碼后得到的數(shù)組，output輸出給解碼器，使用時(shí)注意數(shù)據(jù)類(lèi)型。以下是重采樣的部分

float*in = malloc(totalSampleCount * sizeof(double));
for (size_t i = 0; i < totalSampleCount; i++)
{
in[i] = input[i];

}double irate = 1; /* Default to interpolation */ double orate = 1.1; /* by a factor of 2. */size_t olen = (size_t)(totalSampleCount * orate / irate + .5); /* Assay output len. */ float* out = (float*)malloc(sizeof(float) * olen); /* Allocate output buffer. */ size_t odone;soxr_error_t error = soxr_oneshot(irate, orate, channels, /* Rates and # of chans. */in, totalSampleCount/channels, NULL, //注意是每個(gè)通道的點(diǎn)數(shù) /* Input. */out, olen, &odone, /* Output. */NULL, NULL, NULL); /* Default configuration.*//* Tidy up. */ drwav_int32*output = (drwav_int32*)malloc(odone * sizeof(drwav_int32)); for (size_t i = 0; i < odone; i++) {output[i] = out[i];//printf("%d\n", output[i]); }
