Regardless, you should re-analyze all files in VirtualDJ after you apply mp3Gain on them. If you prefer mp3Gain, it might make sense to set autoGain in VirtualDJ to no, although in that case you have to remember to use mp3Gain on all new files as well. One advantage of mp3Gain is that it alters the file itself, so the gain will also be applied in any other programs you use to play back these files. In VirtualDJ however, the gain calculated is applied at an early stage, and thus additional headroom, a lower channel volume, a lower master volume or the limiter would prevent this distortion from occuring. One disadvantage of mp3Gain is that the gain that it applies could cause some peaks in the track to clip and thus distort these peaks in order to bring the average loudness up to a normal level. ![]() Since VirtualDJ already has an auto-gain algorithm, it is not required and doesn't have a useful effect to use mp3Gain as well. If you decide to use this, remember to re-analyze the tracks in virtualdj after, since the gain value that VirtualDJ analyzed previously would be incorrect after the file had been changed by mp3Gain. Mp3gain is a program based on the replayGain algorithm to even out the volume differences between tracks, and is therefore an alternative to autoGain in virtualdj. It is therefore not recommended to use this setting. We found that many people used this feature incorrectly however, which led to gain being set too loud and as a result causing distortion in the sound. In this case the explanation above still applies, but if you move the gain slider for a song, it is remembered and automatically applied the next time. It is also possible to make small adjustments by increasing or decreasing this value if necessary. The easiest way to fix those is by opening the Tag Editor for these tracks, and manually reset the gain to 0 dB, which means vdj will play these files at their original gain. This can be the case with classical music, which can have a high dynamic range with very short peaks of higher volume and many parts that are supposed to be more silent. Incorrect detectionĪlthough the algorithm used by VirtualDJ is fine for most music, it is possible that it detects the loudness incorrectly for some songs. If they are already at their max, invest in more powerful speakers and/or amplifiers as needed. If you need a structurally higher volume, increase the master volume, or the gain on your amplifier or speakers. This will only cause the limiter to kick in, rather than actually boosting the volume. It is still possible to use the gain knob to make adjustments to the gain when required (for example boosting a quiet passage in the song or temporarily lowering the volume if it's too loud) Note that the gain should not be used higher than the 12'o'clock position structurally. This makes it easy to control the gain with a controller, since it's easy to set it to center position for each track. With gainSliderIncludesAutogain set to yes the autogain is properly applied when the gain slider is at the 12-o-clock position. ![]() With autoGain set to auto, virtualdj will then lower or increase the gain of the track so that all the tracks you play have a similar volume when played, regardless of how loud it was recorded. This is done either when explicitly asking virtualdj to scan the track, or the first time an unanalyzed track is loaded. These are the recommended and default settings to keep VirtualDJ at: - autoGain: auto - gainSliderIncludesAutogain: yes For each song, VirtualDJ analyzes the loudness of the track.
