SoX 13.0.0 Released

I am happy to announce the release of SoX 13.0.0.

You can download both source code and win32 binaries from
http://sf.net/projects/sox

This is a major release of SoX and we took this occasion to greatly
enhance the command line options and output display of the
program. Please expect some script breakage because of this.

This release contains the largest collection of new features
and bugfixes to date. The SoX project has two new full time
developers, Rob Sykes and Reuben Thomas, to thank for this.
Welcome aboard!

The following changes have occurred since the release of
SoX 12.18.2:

File formats:

o Support for .caf, .paf, .fap, .nist, .w64, .nist, Matlab 4.2/5.0
(Octave 2.0/2.1), .pvf, .sds, .sd2 and .xi file formats via libsndfile.
If available, libsndfile can also be used to handle all the other file
formats it understands. (Reuben Thomas)
o Add FLAC support (robs@users.sf.net)
o Support Maxis's XA format. (Dwayne C. Litzenberger)
o Add support for 24-bit PCM raw, wav (WAVE_FORMAT_EXTENSIBLE) [FR# 801015],
au, aiff, & flac files. (robs)
o Add AIFF-C output support. (shashimoto)
o New .ima file format for raw IMA ADPCM. (robs)
o Allow the rate and number of channels of .au files to be overridden
by command-line arguments. (robs@users.sf.net)
o Add seek support for GSM data in WAV files. Rafal Maszkowski
o Allow encoding quality to be specified (FLAC & Ogg, but not
MP3 yet). (robs)
o Rename -b to -1, -w to -2, -l to -4, -d to -8, and mask to dither.
(robs)
o New options for specifying endianness (and separate options for
nibble & bit reversal) [FR# 1621702]. (robs)
o Improved multi-channel file reading; fixes [1599990]. (robs)

Effects:

o Equalizer effect (Pascal Giard)
o bass and treble altering effects. (robs)
o New optional rabbit resample routine, using libsamplerate
(aka Secret Rabbit Code). (Reuben Thomas)
o Added allpass filter effect. (robs)
o Documented the butterworth filter effects; added variable Q. (robs)
o "rate" effect made an alias for "resample".
o Visualisation of various filters' frequency response via Octave. (robs)
o Can now specify width of many 2nd-order filters as: Hz, octaves,
or Q. (robs)
o Dither/mask amount now specifiable. (robs)
o Consistent (and hopefully complete) clipping detection and
reporting. (robs)
o Allow command-line time parameters of < 1 sec to omit the
leading 0. (robs)
o Improved synth usage and improved the synth entry in the man-
page. (robs)
o Higher quality audio speed adjustment; also fixes [1155364]. (robs)
o Replacement flanger effect; also fixes [1393245]. (robs)
o Added silence padding effect. (robs)
o Added ability for noiseprof to use stdout and noisered to use stdin
[FR# 1621694]. (Reuben Thomas)
o vibro effect name deprecated in favour of tremolo; this effect
reimplemented as a special case of synth. (robs)

Other new features:

o Remove soxmix. (Reuben Thomas)
o Preview mode now removed, as all it did was use rate rather than
resample, and rate has been removed.
o -V now gives only user-relevant messages, use -V -V to get
developer-relevant messages. (robs)
o -V output much improved and expanded; now includes display of
(auto-)selected effects. (robs)
o sox man-page overhaul, new soxexam man-page entries. (robs)
o Added command line options for specifying the output file
comment. (robs)
o Added ability to merge e.g. 2 mono files to 1 stereo file
[FR# 1297076]. (robs)
o Removed the restrictions whereby multiple input files had to have
the same data encoding & size, and in most situations where they
had to have the same # of channels, and for play where they had
to have the same sampling-rate. (robs)
o Options to apply replay-gain on input; enabled by default
with `play'. (robs)
o Can now use Ctrl-C to skip to next track when playing multiple
files (e.g. play *.mp3); Ctrl-C twice to exit. (robs)
o Added --interactive option to prompt to overwrite pre-existing
output file. (robs)
o Added large file support. (Reuben Thomas)

Bug fixes:

o Fix writing MP3 files on AMD64 processors.
o More fixes to MP3 tag reading. Sometimes tags were
detected as valid MP3 frames.
o Fix to stop, avoiding a crash, when starting of effects fails.
(Reuben Thomas)
o Fixed a bug introduced in 12.18.2 that stopped the draining
of effects from occuring. This had stopped the reverse effect,
among others, from working. (Reuben Thomas)
o Several effects are now optimised out in situations where they need
do nothing, e.g. changing rate from 8000 to 8000, or changing volume
by 0dB [Bug# 1395781]. (robs)
o Fix rounding error when reading command-line time
parameters. (robs)
o Fix nul file hander ignoring other format options if rate
option has not been given. (robs)
o Fix synth length accuracy. (robs)
o Fix broken audio when downmixing with any of the following
effects: synth, deemph, vibro. (robs)
o Fixed deemph & earwax effects to work with MP3, vorbis,
& FLAC. (robs)
o Fix wav file handler discarding the last PCM sample in certain
circumstances. (robs)
o Fix [1627972] AIFF read bug when MARK chunk present. (Richard Fuller)
o Fix [1160154] VOX to WAV conversion problem. (robs)
o Removed (for output file only) the potentially
problematic -v option. Use the vol effect instead. (robs)
o Improved the accuracy of integer and floating point PCM
conversions. (robs)
o Don't go into a loop on zero-padded WAVs. (Jorge Serna)
o Fix to AIFF writing to avoid writing invalid files in some situations.
(Reuben Thomas)
o Fix compander effect bugs: [1613030] Compand fails to compress
clipping, [1181423] compand with 0 sec attack/release. (robs)

Internal improvements:

o More and better self-tests. (robs@users.sf.net)
o Build system overhaul to use the full set of GNU autotools.
(Reuben Thomas)
o Add new getopt1.c to win32 project file.
o Remove old, optional rate change and alaw/ulaw conversion code.
(Reuben Thomas)
o Removed the old internally invoked (but mentioned in the man page)
copy effect. (robs)
