Yes, I think using the ffmpeg decoder might help get better decoding results in cases with near full-scale MP3s. Development of this decoder has stopped in 2004 and there definitely are known issues with it (fre:ac used that decoder before, but switched to mpg123 which is still getting improvements to this day, because of too many issues with libmad). The MP3 encoder component would then demand normalized input and a normalization step would be automatically added to the conversion DSP chain.Īs far as I know, Audacity still uses the outdated libmad MP3 decoder.

32 bit float format can have out of range samples which (with the current code) would be clipped before being fed to the encoder.įre:ac will get normalization support after the 1.1 release, so in a future release this will hopefully not be an issue anymore. 16 and 24 bit integer formats cannot have out of range samples by definition, so the data fed to the MP3 encoder will always be in the valid range. The documentation says input must be normalized to the +/- 1.0 range, so that probably means no.įor fre:ac that is probably true. It comes with several different presents for the LAME encoder.

The utility currently converts between MP3, MP4/M4A, WMA, Ogg Vorbis, FLAC, AAC, WAV and Bonk formats. Download Audio Normalizer - Analyze the loudness in your audio files, then normalize it with the help of this software utility that comes with support for MP3, FLAC, OGG, AIFF, and other popular. I'm not sure if the LAME encoder can handle out of range values when using 32 bit float input. fre:ac is an open source audio converter and CD ripper that supports a wide range of popular formats and encoders.

is this useful to do for the purpose of importing mp3's with a more truthful representation of the audio contained by an mp3 source in audacity?

is this true?Ģ- am i to glean from this thread that the mp3 encoder freac uses does a much better job encoding mp3's from 16-bit wave source than 32-bit wave source?ģ- does audacity's mp3 decoder not represent a truly accurate display of mp3 material imported into it? and is this still the case with their latest version (2.3.3)?Ĥ- upon reading this audacity thread, i notice there is a way to change the decoder audacity uses to decode mp3's. in that you could have encoded material over that boundry (to a certain point) without any real loss of audio. I apologize if my audacity-related questions go beyond the scope of this discussion, and if my questions are novice level stuff, but reading this thread makes me think of a few of questions.ġ- i was lead to believe that the 'clipping' boundry of 16 or 24-bit wave land was not recognized by mp3's.
