Un programma per misurare la compressione dei CD (ovvero, la Loudness War)

**Bonny84** · 30-05-2009, 13:16

qualcuno di voi ha provato con degli xrcd?? Sapevo che avevano fatto una versione di brothers in arms dei dire straits con questo formato ma non sono mai riuscito a trovarla...peccato

A volte i gruppi meno conosciuti producono lavori meno schifosi (mi sia passato il termine) rispetto a gruppi più conosciuti. Non dico che ci siano esplosioni di dinamica, ma almeno non viene voglia di lanciare il CD dalla finestra. RImane il fatto che si potrebbe fare (molto) meglio.

Questi sono gli Unifaun, un gruppo progressive che omaggia apertamente i primi Genesis.

Mi allego alla discussione. Avevo intenzione di comprare qualche CD dei "Van der Graaf Generator". Ero indeciso se prendere la versione originale o la remaster del 2005

Voi su quale investireste non potendo ascoltare gli originali ? Può la differente compressione inficiare la dinamica ? Grazie in anticipo

**joe49sae** · 04-06-2009, 20:33

A priori non lo so dire, ma basta comprimere un file Wav in mp3 e fare la prova a confronto col programma....penso sia fattibile

**Deuced** · 24-06-2010, 12:28

riuppo il topic...ho seguito i link e non mi fa scaricare il software nonostante mi sia registrato.

Mi sa che l'hanno reso a pagamento

**Avenger** · 24-06-2010, 14:09

Lo trovi qui:

L'indirizzo diretto per il download è questo:

**Deuced** · 25-06-2010, 11:29

grazie,scaricato

Pensavo di essere diventato sordo,invece molti cd che ho sono veramente una schifezza (dr fra 5 e 6)

Per fortuna quelli di jazz che posseggo,anche se rimasterizzati e recenti sembrano immuni da questa tendenza

Non mi resta che acquistare The Nightfly di donald fagen,sembra essere la migliore incisone presente sul database...

**cattivik83** · 25-06-2010, 14:12

ottimo il cd di Donald, scelta giusta
