I believe the clipping is caused by the lossy nature of mp3 it will happen with other lossy formats too. The mp3 is not exactly the same as the original, so some peaks might decrease while other peaks increase and cause clipping. I don't think you can predict how much higher the peak of the mp3 will be compared to the original, so it will be hard to create an mp3 with a peak exactly at 0dB.
However there is a solution. To avoid clipping you can use software that decodes the mp3 at a lower volume, like Foobar with replaygain or preamp option. The result will be restored peaks and less clipping! Check out this wave comparison. On the right the original mp3 decoded at normal level, you can see it's clipping. On the left is the same mp3 decoded at lower preamp with Foobar and the peaks are somewhat "restored".
Last Edit : by Mark7. Clipping is with lossy encoding is normal. I've yet to see a compelling reason why it should be addressed if it isn't audible. I've issued more than a few challenges for people to show me proof that they can identify clipping as a lossy artifact using settings that would otherwise be transparent with actual music.
So far there have been no positive responses. Last Edit : by greynol. Decoding to floating point should prevent clipping. In both cases you'll see that the tops are not really cut off but just overflow 16 bit integer samples. Last Edit : by googlebot. I'll try to avoid such situation. Like Mark7 says, clipping with mp3 and similar lossy encoders can appear in quite a natural way for more info, read how the sound is formed from sine waves and that lossy encoders can add and remove some of them To listen to the mp3 file, it has to be in integer mode in some place between the player's decoder and the soundcard's DAC.
Saying that one can use floating point is a bit misleading. Of course, if you have a digital volume that receives floating point audio, and you use it to reduce the volume like Replaygain with negative values , it can prevent the clipping, but that's a side effect, not a prevention mechanism per se.
Also, I would like to add that 24bit integer has just a higher SNR than 16bit integer. It does NOT have a higher 0dBfs. Something that clips at 16bits, still clips at 24bits, if you want to keep the same volume. I mention this because a reader could get an incorrect impression from your sentence. Bobolith: Like others have said, this clipping is generally not audible although there have been audible cases, and definitely a synthetic case can be made to be clearly audible.
There's the option to live with it, and the much more used solution of using Replaygain, like googlebot suggested. Players that use replaygain can reduce the volume while decoding, which prevents the clipping since the mp3 file is not clipped, just the decoded audio when decoded to integer. Meaning, at least there's rhyme and reason why some songs are louder than others.
Because before I looked carefully, I was starting to think MP3Gain was simply out to lunch on its volume assessments. And haha, yea that does seem like alot of work, esp. I'll have to think about it Thanks again.
Those changes will show up on your iPhone. But, I warn you, the slightest change will be more than one click in mp3gain. Clayton, another Q: Clipping. I normally set target volume at But, I just got new Apple earphones old ones were Sony.
Apple sounds great With Sony I rarely passed the mid-point in volume on my IPod. With Apple, I probably have to click 2 or 3 times passed midpoint I don't think that is a big deal or anything. But, I was wondering, what if I upped my target volume to say 95 or That would probably allow me to not have to turn up the volume so high on my IPod. But, I'm worried about clipping. Like, if a song is clipped, does that mean I'm not gonna hear certain ranges of the song anymore?
Because even at But I can't say I notice any difference If you're not approaching the maximum volume setting on the device but you're using a target volume that causes clipping you should be using a lower target volume setting in an attempt to avoid clipping altogether.
The default is 89 dB, which is rather low compared to recordings released these days. But if you're matching, then it doesn't matter. If you still have room on the "volume knob" of whatever equipment you're using to play music on then you should avoid clipping the source and simply turn up the volume knob on the playback equipment. If you've run out of volume knob, then you could consider using a higher target volume for the files. But if you still have volume knob left, it is better to use the volume knob.
I see thanks. That makes perfect sense. Oh no! Some styles failed to load. Help Create Join Login. Application Development. Clipping doesn't have one specific sound. Instead, clipping can sound like skipping, as in the sound going out for a moment before returning, or it can sound distorted and unnatural.
Clipping can present in various ways. When you clip audio, this usually refers to the practice of sampling, that is, taking clips of music and using them in other music.

Now, this "tip" is very important, it gives a sound its particular timbre, or what scientists call the audio spectrum. In the end, if you make things too loud, you lose some information, and the sound becomes worse. On analog systems, it's quite more complicated, as natural compression Just dont make things clip.
FYI, the occasional screeching sound you hear from bad mp3s from the 90s is because there is no anti-clipping in those softwares. DigDog said:. Last edited: Mar 8, You must log in or register to reply here.
