Consistant Audio levels and great Segues

PlayIt Live default settings for Track Fading and Silence analysis will provide consistant Segues IF the MP3 or Wave file is saved at it's optimum level. One of the problems with when playing MP3 or Wave Files from different sources is varying audio amplitude. Quieter tracks lead to early transitions and seemingly makes some tracks seem overly loud. Yes, you could use a Compressor/Limiter to control this, but post processing will not change how PlayIt Live responds when in the Playout process.

My experience tells me that you must begin with consistant levels before adding tracks to PlayIt live.

If I hear or see a track is quiet, it's opened in an audio editor, such as Audacity, where the levels are Normalized to peak at -1db. Let me point out that most audio editing software sees the odd peak as the maximum amplitude of the track. The trick to this is to bring these individual peaks down to the overall average. Then Normalise the entire track to -1 dB. To compare, import another audio track that you find acceptable and compare the loudness of the two tracks.

It's not likely that a louder track is actually peaking over -0- db. But if it is, use the idea above to reduce the overall amplitude of the “Hot” track.

Remember: -3db is Half as loud. +3db is double the volume.

Over the years I have known people who use Programs, such as Audacity, to create Chains. Whereas all the titles in a folder are processed to cut silence, Normalize to -1dB and Saved to a separate file that is added to PlayIt Live.

By doing so they feel they have a more consistent sound requiring less Post processing.

I maintain that Original recording have the best fidelity but differ in amplitude. I suggest, if any processing with EQ or compression should happen post digital when being being played as audio, so all tracks are consistently processed at the same settings.

Perhaps these ideas will help you achieve consistent audio levels and great Segues with PlayIt Live.



I've had my copy of MP3 Gain since 2003 (and not needed to update it) but what seems to be the same programme is now on Sourceforge

The simple answer to your question is yes but there are some better explanations at

This is the best address:
mp3gain-win-1_2_5.exe   on first line.  In the one most users download.      the others below it are have specific usages if they apply to you.
The basics are: Add  files, Select them, , then Press Analysis ( tells you where the level is and if there is clipping), and then Track Gain to adjust all.  I use the default 89.5 as max.  When the processes are complete  use the EXIT button on the bottom Right.
If you have performed this process and you load the same titles again, the software will let you know.


That's great.  I will give it a try.  Thanks.

Just so that I am clear .... using MP3Gain does not reduce the quality/fidelity and only resets (normalises) the amplitude parameters; right?


It would be possible to reduce the quality of the MP3 file by setting a level that produces clipping but yes it changes the overall gain setting.

The key thing to avoid with MP3 and similar is multiple decode - encode cycles and MP3Gain doesn't decode and re-encode.

Normalise isn't a word I would use for MP3Gain as that implies setting peak levels, MP3Gain is about subjective loudness not peak level.

If you want to know more on that subject try:-

Okay so to make better transitions between songs, which one do i adjust to make the transitions tighter, cue in, or cue out?, and i what level should i adjust them to, i really don't want to normilize the audio, as it may take away from the original file, i really don't like using compressors or limiters.

Thanks, Andrew 

You can preview transitions and set the gain profile for each mix but that is lots of work. Setting out points and a quick fade might help. Use MP3 gain to get all files to a similar subjective loudness. There are limits to what can be done automatically.

I downloaded MP3 Gain from sourceforge and my Bitdefender found two trojans in the exe file. So I am now ary to down load it.

My guess is that it was a false positive.

I tried downloading the installer from Sourceforge this morning ( mp3gain-win-1_2_5.exe ) and then submitted the download to the Kapersky online scanner and that said the file is clean.

Why doesn't Playit Live have an input volume adjustment....that would make it so easy to adjust audio levels as you go rather than being concerned about running tracks through Audacity. To me it seems crazy not to have one.

I can't comment on "why" but as PlayIt Live is often used for automated playout, correcting the files (ideally using a method that doesn't introduce another lossy decode/encode process) is best.

The "audio processing" plugin is good and can fix problems to a degree with "automatic gain control" but for many purposes fixing the subjective loudness is the right answer.

If you take each logical source (player, quick carts etc.) into a mixer, you can obviously adjust gain as you wish and for "live" use this is the best way to use PlayIt Live.

I use a hardware mixer but there are also software mixers which can be used with PlayIt Live (one being the Voicemeeter Banana).

Wikipedia has a good article on loudness normalisation

Also the European Broadcasting Union (EBU) has further reading on the subject
