MP3Gain first computes the desired gain (volume adjustment), either per track or per album, using the ReplayGain algorithm. It then modifies the overall volume scale factor in each MP3 frame, and writes undo information as a tag (in APEv2, or ID3v2 format) making this a reversible process. The scale factor modification can be reversed using the ...
An MP3 file can be edited without transcoding. Cut, copy, paste, and volume change operations are provided; edits can be previewed, including a command that plays a segment without a selected region (previewing a cut) Audio normalization and pause detection; MP3 recording with ACM or LAME encoder (not bundled) Fast MP3 visualization
ReplayGain is a proposed technical standard published by David Robinson in 2001 to measure and normalize the perceived loudness of audio in computer audio formats such as MP3 and Ogg Vorbis.

These can increase loudness of audio tracks, or level out the volume of highly-variable music (such as classical music, or a playlist that spans multiple music types). This improves the listenability of audio played through poor-quality speakers, or when played in noisy environments (such as in a car or during a party).
Before loudness normalization, one song in a playlist might be quieter than the rest, so the listener would have to turn a volume knob up to adjust the playback volume. [ 4 ] Depending on the dynamic range of the content and the target level, loudness normalization can result in peaks that exceed the recording medium's limits, causing clipping.
Starting with WMP 9 Series, audio CDs can be burnt with volume leveling. Audio CDs can be ripped as WMA or WMA 10 Pro (WMA 10 Pro in WMP 11 and later) at 48, 64, 96, 128, 160, and 192 kbit/s , WMA lossless (470 to 940 kbit/s) (9 Series on XP and later), WMA variable bitrate (from 40 to 75 kbit/s up to 240-355 kbit/s), MP3 at 128, 192, 256, and ...
The name MP4 player was a marketing term for inexpensive portable media players, usually from little-known or generic device manufacturers. [50] The name itself is a misnomer, since most MP4 players through 2007 were incompatible with the MPEG-4 Part 14 or the .mp4 container format. Instead, the term refers to their ability to play more file ...
