MAD (MPEG Audio Decoder)

File Release Notes and Changelog

Release Name: 0.15.2b

Notes:
This release compensates for the recent LAME heresy with respect to Replay Gain: rather than using the 83 dB SPL reference specified by the Replay Gain proposed standard, LAME uses a reference of 89 dB as of version 3.95.1.

Combined with the default pre-amp gain of +6 dB implemented in madplay, this often results in an over-amplified signal and clipping when Replay Gain is enabled.


Changes: * 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.
