dr_wav resample? #191

Closed wushange closed 3 years ago

wushange commented 3 years ago

Hello, I'm an Android application developer. I'm working on JNI recently. I need to resample the wav file just like the resample method in MATLAB. Now I have no problem generating audio with drwav. I wonder if the example method is available for use.

Unfortunately there's no resampling available in dr_wav, nor any other dr_libs library. That's something you'll need to organise yourself. My miniaudio project has a simple linear resampler available that you might be able to extract or use a reference (search for ma_linear_resampler): https://github.com/mackron/miniaudio/blob/master/miniaudio.h

Alternatively there's other resampling libraries out there such as libresample and libsamplerate. I haven't used these before and cannot tell you whether or not they're high quality libraries.

Thank you very much for your timely reply. I'm going to use your miniaudio for the experiment.

I can recommend libspeexdsp. The library gives good results and is much faster than libsamplerate (never used libresample)
