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

e2b62687d6 Rejig includes for alloca in particular - more logic in sysutils, remove from individual files (include sysutils instead), also indent includes in sysutils for a bit more clarity 2020-01-16 11:28:47 +00:00

05e14a6a7d Pull out ms buffer onto the heap (was being used after end of block in which it was allocated on the stack) 2013-05-15 10:55:11 +01:00

6aa75133d6 Avoid an alloca. Allocation is borderline acceptable here, this is very much an edge case 2013-05-15 10:36:10 +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
 2010-03-24 09:44:51 +00:00
Chris Cannam

* Threading fixes (corrections to condition usage)
* Avoid a potential hang when faced with some peculiar stretch factors
* More modular calls out to vectorizable functions
* Solaris build fixes
* Bump version number

1d41c952e8 Update from personal repository. 
* Added an initial "formant preservation" option when pitch shifting
 * Real-time pitch shifting now uses a faster method by default, with
   less variation in CPU usage
 * The code is more amenable to compiler auto-vectorization (through
   e.g. gcc --ftree-vectorize).
