If -0.1dbFS works for you then it makes the most sense. This is completely personal preference though, and applies to your work flow method and the tools that you are using.
You'll end up turning down all the samples you normalized to the max. However if you put individual samples through FX chains in Kontakt, you might get the same clipping problem. If you're using something like Kontakt, to put all your samples in, you can just adjust the overall gain. This leave me to bring up the gain on the mixing screen, where I want to be when adjusting levels. I prefer recording at around -6dbFS, to give myself a little headroom when I use it. Now I have to go into the plug-in and adjust the input gain level. This means if I put a Kick Drum sample on Channel 1, and it's peaking at -0.1dbFS, then I apply some channel strip plug-ins, it's quite likely it'll be clipping straight away. The channel fader on an audio track is post-plugin.

I use Pro Tools where the channel faders default to unity gain in a new project. If you normalize all of your samples to -0.1 dB, then use them in your DAW projects, you'll end up clipping your audio tracks all the time as soon as you use a plug-in. But for inserting into projects, this is fine because level adjustments will be made in the project anyway. So your library of parts/samples each might have a different perceived loudness. Remember that peak level and perceived loudness differs.

And at -0.1dBFS peak, you are saving the audio as close to full scale as possible. So if you were mastering for that use, you would set the peak at -10dB.įor storage and use in a library, I would say that consistency is most important. I was told that limiters in nightclubs can begin to affect the signal at as low as -10dB. 3dBFS Is, I think a safe 'guess' as to where a limiter may be triggered in most common use. o.1dBFS is a peak normalization preset because basically, that is the highest level a sample can be without it being perceived as an overload in some hardware or software. Sometimes a limiter will be applied at varying levels below 0dB to prevent overload and clipping distortion. If there is a limiter of some kind in the next phase of the process. If you know of a better, more efficient way, just comment below.In my experience, it all depends on where the audio is to be used next. For my application, it seems to be fast enough. If you plan to use this on really big audio files, I'd recommend putting this in it's own thread so it doesn't block.
I have tested it with numerous MP3 that have apparently louder or quieter audio from one track to another and it seems to be working nicely. This appears, at least to my ears, to achieve what I wanted moving over from Python. I set a default volume level that will then subtract that from the absolute value of dB and pass that value to the AVAudioEQ's.globalGain property. I am sending an AVAudioPCMBuffer to the method, and using the Accelerate API to do the math, first computing the RMS (power) and then converting that to a Decibile (dB) level. Let filePathURL = NSURL.fileURL(withPath: filePath)ĪudioFile = try AVAudioFile(forReading: filePathURL)ĪudioPlayerNode.scheduleFile(audioFile, at: nil, completionHandler: nil)Īfter many hours of research and digging around, I think I finally have the solution I needed to "normalize" my audio between tracks. Var audioPlayerNode: AVAudioPlayerNode = AVAudioPlayerNode()Įqualizer = AVAudioUnitEQ(numberOfBands: 0)Īnnect(audioPlayerNode, to: equalizer, format: nil)Īnnect(equalizer, to: audioEngine.outputNode, format: nil)
Var audioEngine: AVAudioEngine = AVAudioEngine()

However, I now need to figure out how to analyze the file to determine the peak db/peak gain and adjust the globalGain accordingly to ensure each mp3 is nearly the same in volume without having to fiddle with the volume all the time.

I found the below code here and I have modified it to remove the equalizer bands and add in the globalGain option. I'm working with Catalina 10.15.4 and XCode 11.5. I am using the pydub library in python and am applying a gain adjustment through the apply_gain method to normalize my audio files to a specified dBFS, but I have searched high and low for example code of how to do this in XCode and I'm coming up nearly empty handed. I am trying to convert my python code to XCode for a native macOS application. Has anyone had any success writing native XCode/Swift code to implement ReplayGain, or similar function, or know of where I can find some example code/tutorial that does this?
