From: Hui Wang <hui.wang@xxxxxxxxxxxxx> so far, this test only includes rewind test, it works as below: let lfe-filter process 2 blocks mono lfe channel audio samples, the sample format is PA_SAMPLE_S16LE, save the processed data to the temp buffer, then rewind the lfe-filter back 1 block and 1.5 blocks respectively, reprocess the audio samples from the rewind position, then comparing the output data with previously saved data.
