madplay - MPEG audio decoder and player Copyright (C) 2000-2004 Robert Leslie $Id: CHANGES,v 1.94 2004/02/23 21:34:53 rob Exp $ =============================================================================== Version 0.15.2 (beta) * Applied a minor patch from Florin Braescu for the ALSA audio output module. * Modified the reading of LAME encoder tags to compensate for Replay Gain heresy by subtracting 6 dB from Replay Gain values written by LAME 3.95.1 and later. This achieves a uniform reference of 83 dB SPL in accordance with the Replay Gain proposed standard. * Updated the display of encoder tags to show the Replay Gain reference level. * Updated documentation to mention the Replay Gain reference level and LAME heresy. Version 0.15.1 (beta) * Updated to autoconf 2.59, automake 1.8.2, libtool 1.5.2, gettext 0.14.1. * Added support for Replay Gain to `madplay', enabled with a new -G (--replay-gain) option. * Added new -T (--show-tags-only) option to `madplay' to display ID3 and/or encoder tags without decoding any audio. * Renamed `id3tag' command-line program to `madtag' to avoid conflict with another package. * Improved 32-bit support detection for audio_oss module. * Fixed a problem using the --disable-mmap configure option. Version 0.15.0 (beta) * Updated to autoconf 2.57, automake 1.7.5, libtool 1.4.3, gettext 0.11.5. * Added support to `madplay' for arbitrary resampling ratios. * Added new -R (--sample-rate) option to `madplay'. * Added support to `madplay' for RVA2 (relative volume adjustment) frames in ID3 tags. The "master volume" channel volume adjustment of the first RVA2 frame is now honored, unless overridden by a command-line option. * Added new -A (--adjust-volume) option to `madplay' to override per-file relative volume adjustments (see above). * Added new keyboard controls to `madplay' for dynamically increasing (+) and decreasing (-) the audio output gain. * Changed `madplay' tty controls to be disabled by default when -q or -Q is given (on the assumption these are most often used when running madplay in the background.) * Added new --display-time option to `madplay'. * Changed `madplay' to allow switching to Overall Time even for singleton playlists. * Added new --ancillary-output option to `madplay'. * Added new audio_qnx module (untested) for QNX platforms courtesy of Steven Grimm. * Added new audio_alsa module (untested) for ALSA platforms courtesy of Hod McWuff. * Added new audio_carbon module for Mac OS X platforms. * Changed audio_sun to use the AUDIODEV environment variable for the default audio device path. * Changed audio_hex support to be enabled in all builds. * Changed to use native Cygwin build by default; give --host=mingw32 to `configure' to use MinGW (and avoid a dependency on the Cygwin DLL). * Begun work on a new `id3tag' command-line tool for displaying and manipulating ID3 tags. Version 0.14.2 (beta) * Added a new output module, audio_esd, for EsounD (Enlightened Sound Daemon) support. You must have EsounD already installed before running `configure'. Use -o esd:[HOSTNAME] as args to `madplay'. If --with-esd is given to `configure', EsounD will be used for native audio output. * Added a new output module, audio_cdda, for creating CD audio images. Output is forced to 16-bit 44100 Hz stereo. * Added a new output module, audio_aiff, for Audio IFF (AIFF) format files. * Changed the audio_wave module to initially write ~0 length rather than 0, for better compatibility when output is piped to another program. * Changed audio_oss module to try /dev/sound/dsp before /dev/dsp. * Added new -b (--bit-depth) option to `madplay'. Most output modules now support configurable bit depths. * Added new -i (--ignore-crc) option to `madplay'. * Changed Cygwin builds to use MinGW; resulting Win32 executables no longer have a dependency on Cygwin DLLs. * `madplay' now supports keyboard controls under Win32. * Made use of localeconv() conditional based on results from `configure'. * Made use of assert() portable to systems without . * Fixed my bad fix for avoiding log10(0). Version 0.14.1 (beta) * Updated config.guess and config.sub to latest upstream versions. * Fixed a NetBSD compatibility issue in audio_sun. * Fixed a FreeBSD compatibility issue in audio_oss. * Modified the audio_null output module to compute peak amplitude. * Changed the peak amplitude computation to avoid evaluating log10(0). * Several other small fixes. Version 0.14.0 (beta) * Fixed a possible segmentation fault due to mmap() abuse. * Improved MSVC++ portability and added MSVC++ project files. * Modified the PCM dithering routine for better dithered output. * Added TTY controls and new --tty-control and --no-tty-control options to `madplay'. TTY control keys: `P' pause, `S' stop, `Q' quit, `F' forward, `B' backward. * New time/time-remaining modes with --verbose --tty-control (select by pressing `T'.) Version 0.13.0 (beta) * The last complete audio frame should now be properly decoded even when it is not followed by other data. * Added new --downsample option to `madplay'. Version 0.12.3 (beta) * Added calls to madvise() on supported systems to reduce memory overhead when using mmap(). * Added support for automatic mono/stereo channel selection based on output capability. * Added a new option to force stereo output of single or dual channel streams. * Added a new option to amplify/attenuate the output signal by an amount expressed in decibels. * Output statistics (peak amplitude, clipped samples) are now gathered and displayed after decoding. * Fixed a problem calling setlocale() when NLS is disabled. * Fixed a configure problem when multiple -O CFLAGS are present. Version 0.12.2 (beta) * Fixed another FreeBSD sound compatibility problem in audio_oss.c. Version 0.12.1 (beta) * Rewrote the audio PCM packing routines for (hopefully) somewhat better performance. * Fixed a FreeBSD sound compatibility problem in audio_oss.c with help from Graham Guttocks. * Moved ID3 genre table into a separate file and updated extensions with current list from Winamp. * New Croatian, Norwegian, and Spanish translations courtesy of Mario Horvat, Christoffer Nicolaisen, and Damian Brizuela, respectively. * Added a simple ABX testing script. Version 0.12.0 (alpha) * Changed the build environment to use automake and libtool. A libmad shared library can now be built using the --enable-shared option to `configure'. * Added internationalization support via GNU gettext. New French translation added courtesy of Gabriel Bouvigne. * Changed raw output module to use host-endian byte order. * Added --disable-mmap option to `configure' per suggestion of Erik Andersen. * Debug builds now link with -lefence, if available. * Added `madplay' support for filter chains. This could eventually be extended to support dynamically loaded filters. * Added a new optional fade-in filter. * Rewrote madplay.c to use GNU getopt, and added many new options (use `madplay --help' to see them all.) * Updated the man page for `madplay'. Version 0.11.4 (beta) * Added Sun/NeXT audio file output module (audio_au.c). * Added 32-bit (really 24-bit) output support to OSS module. * Relaxed output sample frequency match requirement. * Fixed endian assumption problem in audio_sun.c. * Added -mtune=strongarm for all ARM targets. Version 0.11.3 (beta) * Joint stereo mode now shows LR indicator during playback. Version 0.11.2 (beta) * Added a dual channel output selection option. * Improved the OSS output module by falling back on 8-bit format if 16-bit is not available, and by using native 16-bit endianness. * PCM output is now dithered for better audio quality. A new runtime option can disable this feature. * Added a resampling feature for unsupported output sampling frequencies. * Centralized sample scaling and formatting in audio.c for the output modules. * Moved the empeg-car audio output support into a separate module. * Added bad-CRC frame muting code to madplay.c. * Changed `madtime' to indicate average bitrates. * Reduced the ID3 genre table memory usage. * Minor code clean-up. Version 0.11.1 (beta) * Improved the robustness of the Win32 audio output module. * Added a short man page for madplay. * Wrote most of the code for madtime. * Wrote code for an experimental multi-stream mixer `madmix' (--enable-experimental to add -x option support for this to madplay). Version 0.10.3 (beta) * Made portable to Cygwin. * Wrote new Win32 audio interface module. Version 0.10.1 (beta) * Miscellaneous code clean-up. * Running madplay with no arguments now gives usage info. Version 0.10.0 (beta) * Added framework for ID3v2 support. * Added prefix parsing for output module selection. * Added audio_raw output module. * Rewrote madplay.c to use high-level interface. Version 0.9.7 (beta) * Added audio_hex module (--enable-debugging) for PCM-level debugging. * Fixed bug in audio_sun module; should work correctly now. * Added -Q (very quiet) option to omit bitstream error messages. * Reduced -v output by eliminating timing tenths. * Fixed problem configuring unsupported sample frequencies, and added user feedback. * Enhanced final frame count reporting to include playing time. * Cleaned up madplay.c somewhat. ===============================================================================
