i cant use a 2 times upsampler....
i want to use an unsynced soundcard with clockdrift as a recording
source. and i really dont want to make any quality compromises.
i need all features of libsrc (slowly changing samplerate, and resample
factors of 1.00001 or so)
Measuring the same example with libsamplerate
with SRC_SINC_FASTEST
gives a throughput of 1233140 samples/second, which means that my code
is about 41 times faster.
Are you comparing apples to apples here?
What is the bandwidth of your resampler?
From the comments in the code it seems that your
resampler is not an
abritrary resampler like mine but an 2 times upsampler. Its
not really
a fair comparison to compare a general time varying resampler like
mine to a 2 times upsampler.
