Ok I must admit I used a wrong terminology here. What I meant to say with the dynamic range was actually more about the overall RMS levels of electronic music. Trance music is far more closer to 'Clip' level then classical u must agree about that.

No Yuli,you are wrong on this issue.
Im (Following the conversation and i dont have much to say than repeating what others here already have apart from.....)

I didnt get which issue I am so wrong about - the Trance being with higher RMS levels then Classical or Jazz, or the whole thing with WAV vs MP3... Enlighten me
Pls note that when I say that about the levels it is not for the better or worse is just as a fact Trance is much more 'squashed' than Classical - Enlighten me if I am wrong here not only by stating that I am but with an explanation so I can learn a bit or two and understand my mistake

About the rsm levels.
Obviously you dont feel comfortable with technical terminology,but 'squashed' doesnt mean nothing to me.
You can easly get all the informations you want if you google for it.
Just google before posting next time.

with the term squashed he means compressed.
with todays trend to sound as loud as possible, almost every production is overcompressed - its dynamic range is reduced in exchange for overall loudness. when it comes to classical music, this is not trendy music, its not meant to sell loads of copies, and people who listen to it and buy, are often demanding highest sound quality, which means this music is not so compressed to achieve as realistic dynamic range as possible. there are records that are specially made for audiophiles with best recording equipment used and very very little comp.
with this dynamic range of a quality record of classical music, the difference is more noticable when it comes to mp3 compr. than for instance with electronica or over squashed pop. high quality speakers are a must. but from personal experience, 320kbps mp3 people can´t differentiate from original. the treshold for most people is around 192. /of course it depends on the encoding quality and parameters/ |

Complex music like psytrance can actually present more of a problem for an mp3 encoder than classical music. Psytrance generally has a very 'full' audio spectrum and constant level of loudness making it more difficult to transparently introduce quantisation noise to any given freqency band...

M'kay, thanks ! But then i have another question: I was playing back to back at a party last weekend and the other guy played some tracks from cd's with burned mp3's. I noticed that he had to boost the input-gain on the mixer on all mp3 tracks. So what's happening: does the encoding-decoding process turn down the dynamic range of the original recording ?

There msut ahve been something wrong with the MP3 encoder/decoder then. A good MP3 encoder or decoder has no effect whatsoever on the volume.

try this:
1. take Wav file and opan it in sound forge
2. put limiter on it (hard limit), let it look like square shape
3.save it as mp320 and then look at the wavform
my opinion:
whan you save wav file as mp3 its just take the wav and squeze/compress it to a different digital format, its cuting the freq & changing the wavform, and that not good.
lets say you want to play them on a PA system, the PA system will add even more compression to them, so the mp3 will be even more compressed, and thats not good, right.
WAV is THE format for Producing,Mastering,djing and so on, so why even think about mp3 whan you have WAV!!!

ummm - not meaning to be rude, but you dont know what you're on about. Do you even know the difference between MP3 compression and Dynamic compression?

Re. processing an MP3:
Limiters and compressors used in club sound systems are placed in the analog signal path, after the MP3 has been decoded to analog audio. At this point there is no difference between audio coming off an MP3 and a WAV (other than - perhaps the absolute quality of the audio  ). |

There is a difference between MP3 and wav even after decompressing and converting to analogue... the MP3 still has the additional masked quantisation noise spread across the spectrum. A limiter or EQ on the PA could effectively 'unmask' some of this noise. |

Dear koalakube,
I dont need to Google to make good sound production.. it's RMS not rsm.. And yeah Trance music features much more loudness and higher RMS levels then Classical or Jazz.
If u think differently please respond with a valid point, and if u want to just thrashtalk then u r invited to PM me and we will continue it privately
"Squashed" = over compressed, over limited almost to the edge of clipping, so it will sound 'big' on big rig. Many times it achieves the other way exactly - sounds "Squashed"

Well guys.
The idea behind mpeg algorithm is that some guys came up with an idea that whatever freqs the human ear cant hear or feel must be cuted off so that the files are smaller from data aspect.
In an mp3 file that is 320 you must have a really trained ear to understand the differences(many hours of studio).In a club I dont think there is a chance to hear the difference unless the file is bad exported to mp3 or the source material is a crap. |
