Will different encoders give you different volume levels?
Will different encoders give you more bass, etc? Is there a way to measure volume level easily? Thank you |

Ideally, each MP3 encoder will produce output that sounds identical to the original audio material. There might be some differences in volume levels, but if this happens, the MP3 encoder is doing it wrong. One way to measure volume level is ReplayGain, which analyzes volume according to how our brain hears it, producing a figure that allows us to compare roughly how "loud" two different tracks are.

Usually audio editors can display the RMS levels (expressed in -dBFS RMS) with its meters or with some sort of analyzer. WaveLab, for instance, has an off-line analyzation feature that scans a loaded file and reports on its RMS level, its peaks, errors, etc.
Otherwise, you may be able to use a meter plug-in to the same effect if your editor/DAW supports them. -------------------- www.ron-jones.net

The problem is that human frequency response is not flat, so unless your wave editor or plugin can compensate, you're really not measuring volume in the way a human would perceive it.
ReplayGain, OTOH, does compensate. Maybe you can find a ReplayGain or similar plugin for your editor. This post has been edited by greynol: May 1 2009, 21:06 |

Install/open foobar2000. Compute ReplayGain values for both MP3s (select both -> right click -> ReplayGain -> Scan Per-File Track Gain). Enjoy.

Or simply use MP3Gain to scan the files (and to adjust the volume, if you wish to).
