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

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

c26dc1dc88 * Add centre-focus option (mid/side processing) 
* Simplify RingBuffer and add explicit memory locks
* Fix hang with certain unfortunate combinations of parameters
* Bump version to 1.7

c45acda473 * Fix failure to remember that we have constructed an interpolator 
window already (#25).  Also avoid using alloca for substantial buffers
* Lose FFT::getFloatTimeBuffer and getDoubleTimeBuffer -- it's too
unclear when it's safe to use them and it's safer to control sizes externally.
In RB with smoothing on, these buffers were incorrectly being used for window-si
zed calculations (larger than FFT-sized).
* Fix some incorrect buffer resize sizes
* Build fixes for OS/X

0b8c1bd90b * Pull across from main repo: Fix silent channel of output when processing with band-limited transients option; include libresample support. Also update copyright dates. 2011-01-07 21:46:36 +00:00
Chris Cannam
99ba629361 * More work on framing, interpolation and scaling for longer window than FFT size. 
This adds the --smoothing option to the command line tool and SmoothingOn/Off
  options to the API, introducing a double-length window with presum FFT and
  time-domain smoothing.  Behaviour elsewhere _should_ be unchanged.

49cf25d724 * Further work on handling distinct analysis and synthesis window and FFT sizes 2010-05-25 21:49:05 +01:00
Chris Cannam
3ed58ba356 * Separate out analysis and synthesis window sizes from FFT size. 
This is an internal change only, so far -- results should be
  unchanged from 1.5.0.

87dc720243 Update from main repo. 
* Add a more reliable transient detection mode, and make the mode
   selectable using OptionDetectorXXX flags -- the new method is
   the default
 * Band-limit transient detectors to avoid being distracted by
   inaudible garbage
 * Add a key-frame mapping facility for variable stretch ratio
   management during offline stretches
