Ni -14 #LUFS, ni -16. Tampoco -18, como lo propone #ReplayGain o la #EBU #R128.
La «zona segura» para normalización de audio digital con pérdidas (“ #lossy”) es -19 o -20 LUFS (especialmente en audio lossy con tasas de transferencias muy bajas, como 32 kbps en estéreo, o 16 kbps en monoaural, que es en donde suelen darse sutiles desperfectos en la ganancia del audio digital).
La exigencia de la #UniónEuropea se quedó corta. 🤭

Since the #PNG spec is getting some updates, I was thinking... you know what would be sick? Baking classic #lossy compression right into PNG.
I don't mean #JPEG or anything like that. Not even the #LossyPNG scheme I enjoy using where I reduce the number of colors to reduce the entropy. That wouldn't need any changes to the spec.
I'm thinking #Amiga HAM modes! Instant 3:1 (well, 2.4:1) lossy compression with (hopefully) minimal artifacting. That would be SICK!
Makes me want to throw together a Python script or something to read PNG files, apply the HAM "compression," and then see how the output looks. It wouldn't provide much compression savings with regular PNG, it would need a change to the format. But since I never had an Amiga, I'm curious to see how it looks, and how well it might scale to modern image resolutions.
Conceptually, it's not much different than 3:1 horizontal chroma subsampling, but might actually look a lot better.
Quick explainer: instead of having a 24-bit-per-pixel image, you have a 10-bit-per-pixel image, where the first two bits are a mode selector, and the last 8 bits are the actual pixel data. The modes are Hold and Modify{R,G,B}. Modify{R,G,B} modify just the red, green, or blue component of the 24-bit color for that pixel with the 8 bits specified. The modify mode assigns that pixel to be equivalent to the 8-bit value from a pre-defined palette or some pre-defined bit-assignment mode like RRRGGGBB or something. So basically, the horizontal color resolution is divided by 3, but sometimes you get lucky and there's no noticeable loss.

We are looking for software to #silence a part of #MP3 files without re-encoding other parts (and thus degrading quality/integrity).
Any suggestions?
Bonus points if the software can produce #bleeping sounds too, not just silence. There was freeware many, many years ago called #mp3Trim, which could cut #mp3Files and could add #fadeIn and #fadeOut. It seemed to change discreet blocks of the mp3 file. You couldn't select precise times.
