It does absolutely no re-encoding and simply adjusts magnitude values in the mp3 file itself to change the volume.

It is not generally recommended for your main collection as it is modifying the files from their original state, but it can be very useful for portable media players.Ī program called mp3gain can do the second option and reversibly adjust the volume of mp3s. The second method does alter your file, but because the underlying data is not modified it loses no quality, hence the adjustment can be done losslessly. Depending on the audio file format, the process may also be lossy in the sense that it could irreversibly push a signal above the format's maximum amplitude (resulting in clipping) or below the minimum (resulting in silence). For example, MP3 and AAC files can only be losslessly modified in 1.5 dB steps.

Limitations of the audio file format may prevent precise (finely tuned) gain adjustments with this method. If no "undo" info is saved somewhere, it may not be possible to restore the original audio data.

In this scenario, only one type of ReplayGain (Track Gain or Album Gain) can be applied. In the audio data method, the file's actual audio data is modified so that its natural/default playback volume is at the target level. And there's no standard for where and how ReplayGain info is stored each implementation uses different formats and puts the info in different locations.

Not all audio players/decoders know how to read and use ReplayGain information stored in metadata. If audio data was also changed, the metadata can contain "undo" info. The volume-change information can be very precise. In the metadata method, information on both types of ReplayGain (Track Gain and Album Gain) can be stored. Calculate the volume level and adjust a multiplier level in the mp3 data.Calculate the volume level of the file and add a new tag, letting compatible programs adjust volume on the fly.Mp3 volume level data can be adjusted losslessly, just as a JPEG picture can be losslessly rotated. The technique is used by a number of programs and the levels are calculated by an algorithm called ReplayGain. If you export a high bit rate MP3 at the same bit rate you are helping to minimize quality loss (but are not saving anything in file size).Yes. The penalty of the higher bit rate is that the new file would be larger and that file merge tools might no longer be able to join the new MP3 to others that had the original bit rate. If you export a low bit rate MP3 at the same bit rate as the original you will be degrading its quality much more than if you exported it at a higher bit rate. Click File > Export > Export as MP3, then click the Options button.You can also use standalone programs like MediaInfo.

Find out the bit rate of the imported file by opening it in Windows Media Player and clicking File > Properties, or in Apple Music/iTunes, right-click or control-click over the file and click Song Info/ Get Info.If you need the exported MP3 to be the same size as before: If you import an MP3 file into Audacity, then after export you find it is much larger than before, this is because the bit rate you exported it at is higher than the bit rate of the original file.Īudacity defaults to 128 kbps bit rate then remembers the last used bit rate if you change it. Why is my exported MP3 larger than the imported one? The higher the bit rate you export at, the larger the file will be, so giving a greater time penalty if you enable virus scanning. If it does not, there could be a number of reasons, for example if you have a virus scanner set to scan all created files, this will slow the process of writing the exported file considerably. Now when you export the MP3, the process should go smoothly and quickly.

If there is any silence added to the end of the track as a result of the resampling, you can select and delete it. To do this, select all the track by clicking in the Track Control Panel, then Tracks > Mix > Mix and Render. Try resampling the track to your chosen Project Rate before exporting as MP3. As a result, resampling has to be done while exporting, which can create problems on long tracks. If Audacity crashes or hangs when exporting MP3s, or the export takes a long time to process, the usual reason is that your chosen Project Rate (the sample rate bottom left of the Audacity screen) is very different from the sample rate of the audio track on the screen (as shown in Hz on the Track Control Panel above the mute/solo buttons). Why does Audacity crash or use excessive processing time on MP3 export?
