Adding the Rational Resampler, with decimation = 2 and interpolation = 3, works in terms of resampling. The two separate wave files created before and after resampling sound correct. However, when I am listening to the audio in real-time, there are severe audio crackles and distortions. I also notice that there are a lot of audio over-runs in my console output: >>> gr_fir_fff: using SSE aUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaUaU This behavior is the same, whether I run GNU Radio natively on my iMac or inside a virtual machine using both Ubuntu 10.04 and 9.10. What do you think the root cause is?
