When running the EVS decoder at 48 kHz, it crashes in the HQ core due to the short length of buffer `synth[]`.  The issue can be observed after SHA-1: ebf10d0b6924fb45346d9e863aed1397d3871066 and is related to the missing use of function `delay_signal()`. I will revisit the use of `delay_signal()` in BASOP such that it matches its use in FLP.
