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

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

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.

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

abf577ee9d * Some code rearrangement
* 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).
