<a name="054010d9"></a><b>MP3, AAC or Vorbis - What is the best compressed audio format?</b><br>
<br>
This question can NOT be answered in general. The best audio format is the format that works best for you!<br>
<br>
Having said that, there are a few things to consider. First of all: All output formats supported by LameXP,<br>
except for FLAC and PCM/Wave, use a lossy(!) kind of compression. That applies to MP3 and AAC as well as<br>
Vorbis. Consequently with these formats a certain quality loss is unavoidable when re-encoding/converting, no<br>
matter what. This is called "generation loss". Nonetheless all three formats (MP3, AAC and Vorbis) are able<br>
to retain an EXCELLENT audio quality, given that the chosen bitrate (quality level) is sufficient/reasonable.<br>
<br>
Secondly, the audio quality does not depend on the audio format and the chosen bitrate only. It also depends<br>
greatly on the encoder software that is being used. LameXP uses the LAME MP3 encoder, probably the most<br>
sophisticated MP3 encoder out there, the Nero AAC encoder, one of the best AAC encoders available, and the<br>
aoTuV Vorbis encoder, an improved/tuned version of the reference Vorbis encoder. Consequently LameXP provides<br>
you with state-of-the-art encoders, which ensures maximum encoding quality for ALL supported output formats.<br>
<br>

Hint: The Nero AAC encoder supports a variant of the ABR mode, the so-called "2-Pass" mode. That mode scans<br>
through the entire file once (first pass) before the actual encoding is performed (second pass). This way the<br>
encoder is able to distribute the bits over the entire file and still hit the desired target average bitrate.<br>
It should be obvious that the advantages of the "2-Pass" mode come at the cost of increased encoding time.<br>
<br>
Hint: A common mistake done by people comparing rate control modes is choosing a bitrate that is too high. Of<br>
course only files of an identical (average) bitrate can be compared by quality. But if that bitrate is chosen<br>
too high, you won't be able to draw any conclusions from the test. That's because at a certain bitrate even<br>
the CBR mode will retain excellent quality. In that situation VBR mode or ABR mode can't give an even better<br>
quality for obvious reasons. But drawing the conclusion that there is no difference between CBR mode and the<br>
VBR/ABR modes would be very wrong! The differences will become significant when using a reasonable bitrate.<br>
Another mistake is starting with a low-quality source file and concluding that all modes perform equally bad.<br>

LameXP can use them. Simply unzip the files 'neroAacEnc.exe', 'neroAacDec.exe' as well as 'neroAacTag.exe' to<br>
