a218ad42fa Constrain to +/- 2 octaves (+ semitones) as it's less demanding of block size; minor tidying 2021-05-14 14:26:52 +01:00

b463cf5565 Fix wrong accumulator type - this fix makes the detector a little more sensitive, which is not necessarily good, but the previous accidental behaviour exaggerated the difference in results between float and double precision ffts 2021-03-09 17:22:41 +00:00

dbaaf12598 Hm, those settings weren't as well-behaved as I thought. I wonder if there is some unpleasant randomness here 2020-10-22 17:13:55 +01:00

d05806450a Avoid compiler complaints about dynamic array syntax. This is no better code, bu 
t it's less sensitive to compile options.

c1108834c1 In this emergency, increase the buffer size by a factor rather than only by a constant amount - because if this arises because of an overlong increment being broken down into littler bits, we would end up doing it again and again, which is much more expensive. This makes a huge performance difference in cases where a time map ends up mapping very little input into a great expanse of output 2020-09-22 10:35:50 +01:00

661a1d05eb It appears this may be all we need - apparently the occasional odd extra sample (due to incremental rounding) added up and eventually overran the filter. I believe +1 is perfectly good here, but we can afford to be more accommodating just in case 2020-09-16 17:52:33 +01:00
