Revision history for Perl extension Audio::Wav.

0.01  Fri Dec 11 05:54:22 1998
  - original version; created by h2xs 1.18

0.02  Sat Sep 01 15:15:00 2001
  - works on big endian machines!
  - no need for Audio::Tools anymore
  - added support for info & sampler blocks.
  - now honours padding bytes
  - read & read_raw no longer return non-audio data.
  - added error handler.
  - slight speed improvement for read & write methods
  - some other fixes.

0.03  Fri Jun 11 13:29:00 2004
  - minor bug fix to pass tests with Perl 5.8.3 (thanks to Jeremy Devenport).

0.04  Thu Dec 30 07:47:00 2004
  - fixed a bug in Audio::Wav::Read::move_to, now adds where the data actually starts to the position given.
  - Audio::Wav::Read::move_to now rereads data length to see if file has grown since this was last read.
  - added method Audio::Wav::Read::reread_length, rereads the length of the file in case it is being written to as we are reading it.
  - added method Audio::Wav::Read::read_raw_samples which will read X samples in raw format.
  - added method Audio::Wav::Read::position_samples which returns the current audio data position in samples.
  - in method Audio::Wav::Write::add_cue, if sample position supplied is undefined, then the position will be the current position (end of all data written so far).
  - in method Audio::Wav::Write, moved the option of not caching data from the write_raw method to new.

  - Audio::Wav::Read::position_samples should have divided by block_align, rather than multiplied (thanks David Brandt).
  - Fixed bug where unknown blocks weren't skipped (thanks Robert Hiller).

0.06  Wed Mar 22 12:00:00 2006
  - Fixed a circular reference in Audio::Wav::Write::Header that was causing memory to leak (thanks Sumitro Chowdhury).
  - Tidied up bits and pieces.
  - Added very basic support for WAVEFORMATEXTENSIBLE.
  - When writing files, finish() will now be called by DESTROY if necessary.

0.07  Sun Feb 07 18:05:41 GMT 2010
  - change API so you can call Audio::Wav->{read|write} w/o new() if preferred
  - increase pure perl read speed by a factor of ~2.4
    * remove unnecessary bounds check
    * put block in closure, avoiding double hash lookup
    * put $block assign in _init_read_sub, put read_sub in closure, too
    * pull $handle into closure:
    * get rid of closure, and get rid of read() - inline it with $read_sub
  - use Inline::C (if available) to increase read speed by a factor of ~2.3
  - experimental support for reading 24- and 32- bit data (suspected to
    work on little endian machines that use Inline::C)

0.08  Tue Feb 09 06:29:43 GMT 2010
  - fix regression: read() returned bogus samples when Inline::C not available

0.09  Thu Feb 11 14:58:37 GMT 2010
  - Support 24 and 32 bit wav reading w/o Inline::C (from Wolfram humann)
    ( see https://rt.cpan.org/Public/Bug/Display.html?id=36452 )
  - add a META.yml and some other easy kwalitee tweaks
  - Audio::Wav::Read::_has_inline moved to Audio::Wav::_has_inline so
    it can be queried before instantiating a reader (and later be used
    internally for Audio::Wav::Write)
