Beatport, Boomkat mp3´s are clipped
Anyone else here noticed that mp3´s from boomkat goes over 0 db?
I bought 2 albums from them, and both of them are distorted.
Edit: That goes for beatport as well.

Without hearing the original audio it could happen due to the MP3 algorithm itself and the encoding methods applied to the original signal. Iirc if you encode a signal which has peaking anywhere over -1db the resulting encoded file will appear to be clipped at the output when decoded.interceptor wrote:It cant be meant to be that way.

When you encode raw audio to mp3, some high and low end is lost and other frequencies are are boosted as a side effect. Things get clipped unfortunately.
There are ways to minimize this before encoding, such as lowering the volume of the raw audio by -.3dB giving it room for gain. (This is typically enough, but trial and error is the best method)
I've been waiting for years for someone to come out with an encoder that: test encodes, checks how much gain is added, automatically adjusts the levels before really encoding, and voila. That or a true limiter in the encode process, so level is not*lost.

Hi, I agree with kaffein. I tried everything even a limiter (-0.2db) in-between the wav to mp3 conversion, but the result was allways clipping. The only thing that worked for me is lowering the level (with a limiter -3 db instead of -0.2db) or only the normal level -3db lower then normal.
I find it strange that not many people are aware of this fact and as a result you will see a lot of mp3's clip, because it's a error in the different mp3 decoders.

From clipping the playback device, but the mp3 is still fucked.Crash wrote:Your mother's not related!

The problem here is retail outlets getting encodes that have been clipped and selling them.
