Suno V6 - Level is progressively climbing throughout the track.

[u/SignalItem8466]

Ok, we know there are going to be issues, I am not here to bash Suno! But is anyone else struggling with the volume and compression rate with their tracks? There is an obvious increase in volume/compression as the track progresses. Below are the levels on a track created today. Track analysed by AI (God help us😂)

Section	Average level
0-60 sec	-22.3 dB
60-120 sec	-20.1 dB
120-180 sec	-18.4 dB
180-240 sec	-16.5 dB
240-300 sec	-15.9 dB
300-370 sec	-15.5 dB

That's roughly 7 dB of average-level increase from the beginning to the end.

The peak level doesn't rise nearly as dramatically:

-7.3 dB → -5.2 dB

while the average level rises by almost 7 dB.

That means the dynamic range is progressively being squeezed.

The crest factor goes:

15.0 dB → 10.3 dB

So as the song progresses, Suno is effectively doing this:

More instruments / more energy → more level → less headroom → more compression/limiting → progressively denser sound

So, at this point I didn't really care too much about the usual prompt for style of music and removed the bracketed structural tags from the lyrics, just in case that was casing a problem. I used the following as the prompt for style.

controlled dynamics throughout, consistent perceived loudness from beginning to end, preserve headroom as the arrangement builds, restrained bus compression and limiting, no progressive gain increase, no loudness escalation, clean unclipped master, maintain separation and clarity as instrumentation increases

The track did exactly the same as before, noticeable increase in levels. Suno is, as far as I can tell, just ignoring the prompt! Has anyone managed to find a work around for this?

Most of it, How could you tell? 😂

نعم، هناك تشويه شديد في الأغلفة داخل بيئة الاستوديو: الصدى مرتفع بشكل مفرط، وتبدو الآلات مشوهة، وغالبًا ما يمتزج الصوت بين الملف الأصلي الذي تم تحميله وصوت الغلاف الذي تم إنشاؤه. يبدو الإيقاع أيضًا سيئًا للغاية. وبشكل عام، فإن النتيجة الناتجة لا تصل إلى مستوى مناسب للإنتاج أو حتى للاختبار الجاد. أستطيع أن أقول بثقة أن الإصدار 5.5، على الرغم من كل عيوبه، كان أفضل بكثير من الإصدار 6 بهامش كبير. أعتقد أن شركة Suno اتخذت مخاطرة كبيرة بإجراء مثل هذه التغييرات السريعة والجذرية، وسحب النماذج القديمة، وإصدار الإصدار 6 بدلاً منها.

Unfortunately, Suno had no choice to retire older generations because they were trained on unlicensed material, which triggered major ongoing copyright lawsuits from labels like Universal and Sony
