Force value-initialization of array to avoid uninitialized values.

Browse Source 
An automatic undef checker noticed an error in the new
audio_processing_fuzzer. An array was default-initialized, meaning its
contents had indeterminate values. This array was later filtered for
forbidden values, which happened or did not happen based on the
uninitialized values. Hence the error.
