Veranderingen voor v4.70.0 - v4.75.0

  • WavPack Library Source Code - 4.75.0
  • ------------------------------------
  • improved: reorganization for modularity and to improve linking
  • added: assembler optimizations for encode/decode on x86 and x64
  • added: assembler optimizations for decoding on ARMv7 (Linux)
  • improved: several minor speed optimizations using intrinsics
  • fixed: wavpack.pc.in not working correctly on some Linux distros
  • fixed: memcpy() issue causing abort() on OpenBSD
  • wavpack.exe (command-line encoder) - 4.75.0
  • wvunpack.exe (command-line decoder) - 4.75.0
  • wvgain.exe (command-line ReplayGain scanner) - 4.75.0
  • -----------------------------------------------------
  • changed: writing to console title default is off (Linux only, -z1 to enable)
  • fixed: wvgain crashes on bad file arguments (Debian bug #716478)
  • cool_wv4.flt (CoolEdit / Audition filter) - 2.12
  • ------------------------------------------------
  • improved: performance (from assembler optimizations)



Veranderingen voor v4.60 - v4.60.1

  • Compatible with virtually all PCM audio formats including 8, 16, 24, and 32-bit ints; 32-bit floats; mono, stereo, and multichannel; sampling rates from 6 to 192 kHz (and non-standard rates)
  • Multiplatform support including Windows, Linux, and OS X, plus a flash decoder that works virtually anywhere
  • Instantly seekable and streaming capable (and gapless)
  • ReplayGain (including WavPack file scanner and compatible plugins)
  • Uses ID3v1 and APEv2 tags for metadata (including ReplayGain)
  • Error-tolerant block format conducive to hardware decoding
  • Optional "asymmetrical" mode for improved compression
  • MD5 audio checksums for verification and identification
  • Unique hybrid mode (provides high quality lossy + "correction" file
  • Dynamic noise shaping (dns) for optimum quality at lower hybrid bitrates
  • Hybrid mode now operates as low as 2.25 bits/sample (or 196 kbps for CD audio)
  • Free and open source with easy to use library interface and unrestrictive license (BSD)
  • Intuitive command line interface (with wildcards and destination directory)
  • Small, efficient executable (no large programs or dlls to install)
  • Special "low latency" version available for custom applications
  • Self-extracting archives with cuesheets (Windows only)
  • Fully backward compatible to WavPack 1.0
  • Java decoder and encoder now available
  • Complete piping support



Veranderingen voor v4.50 - v4.60

  • added: API for reading & writing binary fields in APEv2 tags
  • fixed: recognize APEv2 tags with footers but no headers
  • fixed: playback of files with 8 streams (15-16 channels)
  • fixed: playback and seeking failed on certain rare correction files
  • fixed: handle case where library makes RIFF header but app adds RIFF trailer
  • improved: channel count limit now virtually unlimited (tested to 256)
  • improved: move all tag functions into new module (tags.c)



Veranderingen voor v4.41 - v4.50

  • WavPack Library Source Code:
  • added: dynamic noise shaping for improved hybrid quality
  • added: option to merge blocks of similar redundancy
  • added: ability to store and retrieve extra mode level
  • fixed: alignment fault on some big-endian machines
  • fixed: compiling with enable-mmx on gcc 4.3.x (thanks Joachim)
  • improved: allow bitrate to be calculated for files down to 1/10 second
  • improved: decoding of corrupt files (prevents heap overrun crashes)
  • wavpack.exe (command-line encoder):
  • added: dynamic noise shaping for improved hybrid quality
  • added: --channel-order option to reorder nonconforming multichannel files
  • added: --merge-blocks option to optimize storage of LossyWAV output files
  • added: ignore -o on Windows for compatibility with Linux version
  • fixed: alignment fault on some big-endian machines
  • improved: reformatted and expanded --help display
  • wvunpack.exe (command-line decoder):
  • fixed: don't ignore fractions of seconds in --skip option
  • added: show extra level and dns status for newer files (-s command)
  • added: ignore -o on Windows for compatibility with Linux version
  • improved: decoding of corrupt files (prevents heap overrun crashes)
  • improved: display bitrate for files down to 1/10 second
  • in_wv.dll (winamp plugin):
  • added: transcoding API (allows CD burning, format conversion, ReplayGain calc, etc.)
  • added: metadata writing API (for Auto-Tag, etc.)
  • added: full Unicode support for info box (older Winamps) and media library
  • added: standard Winamp metadata display & edit for newer Winamps
  • added: option to pass multichannel audio
  • added: option to pass all audio as 16-bit (for better compatibility)
  • added: option to output 24-bit audio when ReplayGain is active
  • added: genre display to info box (older Winamps)
  • fixed: seek bar sometimes vacillates when moved
  • fixed: crash when winamp is opened with files in playlist moved or deleted
  • improved: hi-res audio now output as 24-bit (not 32-bit) for better compatibility (EQ, etc.)
  • improved: performance of adding tracks to library, especially from network drives
  • improved: decoding of corrupt files (prevents heap overrun crashes)
  • cool_wv4.flt (CoolEdit / Audition filter):
  • added: about box
  • added: dynamic noise shaping for improved hybrid quality
  • improved: display bitrate for files as short as 1/10 second
  • improved: decoding of corrupt files (prevents heap overrun crashes)
  • improved: replace "extra processing" switch with a slider (0-6)



Veranderingen voor v4.31 - v4.40

  • added: accepts long option names including --help for full usage info
  • added: new hardware-friendly "high" mode that compresses almost as well as old "high" mode but decodes significantly faster; old "high" mode now available as "very high" (-hh)
  • added: --optimize-mono option added to improve compression of mono material in stereo files (requires at least version 4.3 decoder)
  • improved: "extra" mode levels 1-3 completely revamped, fast enough for use
  • improved: switched to Microsoft Visual Studio 2005 (win32 only)
  • removed: support for Windows 95
