Continuing the mini-guides to the public every time we see today how do you transfer digital audio in high definition on disc, with a very simple application, and above all free: Lplex SourceForge.
Ne avevo già accennato tra le varie soluzioni disponibili, ma adesso vediamo in pratica come si usa (le immagini esemplificative sono in fondo, come sempre).
Ricordo che le altre mini-guide riguardano Foobar2000 , iTunes per l' alta definizione in ambiente Mac , GarageBand (sempre su Mac) per digitalizzare a 24 bit LP e audio analogico in genere.
Aggiungo anche che trasferire su disco audio digitale in alta definizione acquisito vai Internet (la cosiddetta musica liquida ) ha lo scopo di ascoltarlo in un impianto tradizionale e di archiviarlo sempre in modo tradizionale (Physical media) and therefore refer only to those who prefer this solution than the "media server" which we have spoken several times (eg here ). Of course, to read the disc in high definition, which will be a DVD player is also a high-definition, which may simply be a DVD or BD (Blu Ray) and the latest generation of good quality, able to treat native 24-bit audio / 96KHz, such as the Oppo models.
Lplex
But let's get this simple application that you download from its site (the current version is Beta 0.2 for Windows 32) and that requires a simple installation, in practice only creates a directory with the application and other necessary files. You have to first of all a preliminary step . Launching the application with no load (just click lplex.exe) file is created with the initial parameters lplex.ini. We must open it (just click on it and open the application "notepad") and replace the line "video = NSTC" with "video = pal" (NSTC is the standard of television in the U.S. and the product is from there).
This is also explained in the readme.txt file along with many other features not essential to the realization of a disc.
Limits di Lplex
Il secondo passo è la preparazione dell'input, ovvero della musica liquida che vogliamo trasformare in "musica solida" su disco. Lplex supporta solo input in definizione pari 24 bit / 96 KHz, solo stereo (non multicanale) e solo in formato non compresso PCM (WAV) o compresso lossless FLAC. L'ordine con il quale i vari brani saranno scritti su disco è dato unicamente dal nome del file. Se già non è così bisogna quindi rinominare i file premettendo un numero progressivo. Che però deve essere 01, 02, ... 10, 11, altrimenti su Windows l'ordine viene alterato (dopo 1 segue 11). I file con i vari brani devono poi essere inseriti in una directory dedicata, senza alcun altro file.
Use Lplex
Without this simple preparation to start Lplex just drag the mouse on the icon of the application directory Lplex in the directory where you installed (see picture below). Lplex start by opening a window with the DOS command prompt, which will provide initial information on the work progress as a percentage of each file, and the subsequent preparation of audio / video ("multiplexing to mpg) and organization of the DVD format disc ("DVD Authoring" and "Creating dvd image"). All this takes a few minutes, a timescale similar to a burn.
the end will creato un file immagine di estensione .ISO (e nome uguale alla directory) che viene posizionato, a meno che non si modifichi il file .INI del quale abbiamo parlato prima, nella directory adiacente (la successiva nell'ordine) a quella di Lplex. Può anche andare bene così, tanto è un file di lavoro che può essere poi eliminato. Nella stessa directory viene anche creata, in un'altra sotto directory, anche la struttura del DVD (sono due directory AUDIO_TS e VIDEO_TS), anche questi file di lavoro possono essere poi eliminati.
A questo punto il lavoro di Lplex è finito e l'ultimo passo che rimane da fare è creare un DVD partendo dall'immagine .ISO (attenzione: NON dalle directory in formato DVD), operazione that can be done easily with any burner for PC (Black, Deep Burner, or anything you like). The result will be a DVD "universal", which can then work on any DVD player (or BD), although it does not support DVD-Audio. If the TV is connected you will see a black screen, so it must be turned on. To select the tracks you can use the remote control just like when you use the DVD player to read the CD. Only in this case it is not a CD, but a disc in high definition.
Case FLAC is not supported
Lplex may happen that refuses to go with FLAC input, displaying an error message "Unable flac files to decode. "Flac Decoder Lplex added in version 0.2 beta (which is 2006) is not aligned to the latest release of the FLAC format.
You can work around the problem by converting the file to WAV format, using Foobar2000 ( see the post about it) or another program that does the same job. And being careful, of course, keep the resolution at 24/96. Lplex files in WAV format no problem (at least, I've never met ) and then you can proceed safely.
Alternatively you can download the application from the forum for the version currently in development (0.3 beta), where the problem is solved, but it is di una versione non ancora rilasciata in modo definitivo.
E i file con risoluzione diversa?
La maggioranza della musica liquida in alta definizione è in formato 24/96, ma su HDTracks sono disponibili diversi album di provenienza SACD, quindi in formato 24/88.2 e su LinnRecords è disponibile anche materiale in formato 24/192.
Per trasferire su disco questo materiale servirebbe una applicazione più completa, come DVD Audio Solo, che è a pagamento (costa poco, circa 40 $), ma con un po' di pazienza si può fare anche con Lplex.
E' necessario procedere preventivamente ad un ricampionamento (resample) con un programma apposito. Ne esistono diversi, professional and freeware. A simple freeware that works well is called r8brain and is manufactured by a company specializing in music software called Voxengo (I think Russian).
The operation is very simple, you specify the file input and output, the number of bits (24) and the desired sample rate (96,000) and partly by the resampling, getting music files compatible with Lplex.
also pay attention to the quality setting, the default is being proposed is "medium" but you need to select High or Very High, the conversion will be slower (requires basic already for some time) but you can not compromise on quality just when this is our objective.
We should add only that the transition from 192 to 96 should be no problem at all, while from 88.2 to 96, according to many opinions on the Internet can be critical, because it is an upsampling (though limited) and because it is a fraction. I am not able to confirm, it is probably true, but in any case is not an obvious problem and the file you get is perfectly listenable.
I do not know then that the sound effects have all these conversions, which certainly will horrify purists, it is clear that those who want to feel comfortable from that point of view or is it often necessary to handle special cases, choose a complete as the one mentioned earlier.
Who produces this program?
Lplex and 'open source software, distributed under the GNU GPL open and agrees that open software development platform called SourceForge, in turn, managed by the company (American), VA Software who, as is typical in the open source provides (for a fee) maintenance and customizing open source software that has built or has under management. Who uses the software "as it is", as in our case, does not pay anything.
In conclusion
No need to buy a DVD authoring application such as Audio Only or Disc Welder Bronze, with this simple software you can get the desired result only at the cost of some operations in more. Clearly, DVD Audio Solo (which I will devote a future post) is a much more comprehensive program, which allows users to create discs DVD-Audio formats, more comfortable to use, multi-channel formats, as well as several other features. Even Lplex still has other features in addition to those basic illustrated here, which can be found on the guide readme.txt
Images
As always in support of public explanations some example images.
1. Dragging the directory with the mouse (drag & drop) starts Lplex
2. The dialog Lplex with logging production of the disc, in this case Pink Moon by Nick Drake (from which the top image) in resolution 24/96.
3. Lplex dealing with unsupported file formats Flac
