EAC - Exact Audio Copy [Tutorial]

Re: EAC - Exact Audio Copy [Tutorial]

Eu nunca trabalhei com o Audition nem sei que opções de extração tem disponíveis e menos ainda qual o processo que usa para extrair o áudio.

Ainda fiz aqui uma busca com o amigo google mas parece que não há muita gente a usar o audition para extração por isso também não consegui encontrar informação.

O Audition é uma ferramenta que permite digitalizar som ao mais alto nível.


Vejam aqui um excerto do help

Audio format settings

In most cases, you should save uncompressed audio to the AIFF or WAV formats. Save to the compressed mp3 format only when creating files for the web or portable media players.

In a Save As or Export dialog box, click Change to the right of Format Settings to access the options below.
To see the effect of settings changes, note the Estimated File Size at the bottom of the dialog box.

AIFF format settings (*aif, *.aiff, *.aifc)
AIFF is the standard uncompressed audio file format on Mac OS.

Sample Type (available only for 32-bit files)

Sets the audio bit depth. Higher bit depths provide more dynamic range and reduce distortion, though they increase file size and processing time. To determine the proper setting for common output types, see Understanding bit depth.

Integer settings clip audio that extends beyond the amplitude range for a given bit depth. Floating Point settings require slightly more storage space, but retain much greater dynamic range.

Choose 32-bit Floating Point if you want to repeatedly process the file and discard minimal amplitude data.

Note:
To add Author metadata to an AIFF file, use the Dublin Core: Creator field on the XMP tab of the Metadata panel. (See Viewing and editing XMP metadata.)

Byte Order (available only for 16-bit files)

Specifies the numerical sequence for bytes of data. Choose the Little-Endian method for systems with Intel processors and the Big-Endian method for systems with PowerPC processors.

Monkey's Audio format settings (.ape)
Monkey's Audio compresses files to roughly half their original size, using a lossless algorithm that retains sonic fidelity.
Compression

Determines the tradeoff between processing speed and file size. (Fast processing produces larger file sizes, and vice versa.)

MP2 Audio format settings
MP2 (MPEG-1 Audio Layer II) is a lossy compression format particularly popular in radio broadcasting.
Channel Mode

Choose one of the following:

Automatic selects an option below based on the current channel configuation of the file.

Mono produces a one-channel file.
Dual Mono produces a two-channel file with identical audio in both channels.

Stereo produces a two-channel file, processing channels independently, and retaining stereo imagery.

Joint Stereo processes both channels together, reducing file size, but often affecting stereo imagery.

Bitrate

Adjusts the tradeoff between file size and audio quality. Higher settings increase size and quality; lower settings reduce size and quality.

For information about Advanced options, position the mouse over them until a tool tip appears.
MP3 format settings
MP3 is the standard compressed audio format for online distribution.

Type

Choose Constant to apply a consistent bitrate or Variable to change the bitrate based on audio content.

Bitrate (for constant bitrates) or Quality (for variable)

Adjusts the tradeoff between file size and audio quality. Higher settings increase size and quality; lower settings reduce size and quality.

Avoid compressing the same audio to mp3 more than once. Opening and resaving an mp3 file causes it to be recompressed, so any artifacts from the compressing process become more pronounced.

QuickTime format settings (audio-only *.mov)
You cannot adjust format settings for audio-only QuickTime files, which are always saved as uncompressed PCM (Pulse Code Modulation) data.

Wave PCM format settings (.wav, .bwf)
Wave PCM is the standard uncompressed audio format on Windows.

You can include Broadcast Wave metadata in Windows PCM files. (See Viewing and editing XMP metadata.)

Sample Type (available only for 32-bit files)

Sets the audio bit depth. Higher bit depths provide more dynamic range and reduce distortion, though they increase file size and processing time. To determine the proper setting for common output types, see Understanding bit depth.

Integer settings clip audio that extends beyond the amplitude range for a given bit depth. Floating Point settings require slightly more storage space, but retain much greater dynamic range.

Note:
The nonstandard 16.8 and 24.0 Floating Point options are provided for compatibility with previous versions of Adobe Audition. (16.8 was the internal format used by Audition 1.0. 24.0 was an optional setting from the same version.)

4GB Plus Support

Stores files larger than 4GB using either RF64 format, which reflects the current European Broadcasting Union standard, or the Multiple Data Chunks format supported by older versions of Audition.

Note: To ensure compatibility with a wide range of applications, choose the RF64 format for files greater than 4GB.

libsndfile, FLAC, and OGG format settings
The following options are shared by a wide range of formats.
FLAC format uniquely is both compressed (reducing file size) and lossless (retaining full audio fidelity).

Format

Specifies the file format and extension.

Encoding

Specifies the data storage scheme for the file.

Byte Order

Specifies the numerical sequence for bytes of data. The Default Byte Order automatically applies the default for your system processor and is typically the best option.

VBR Quality (OGG files only)

Determines the tradeoff between file size and audio quality. (Higher settings produce larger files, but better quality.)

que retirei daqui.

É uma ferramenta PRO que faz muito mais que ripar audio.

Re: EAC - Exact Audio Copy [Tutorial]

Eheheh, sim Chico, eu sei bem o que é o Audition

Como disse, nunca trabalhei com ele diretamente por isso não sei que opções de "ripping" é que tem.
Para processamento de ficheiros de som sei que é fantástico e permite fazer tudo e mais alguma coisa. A minha dúvida, e razão pela qual não sei responder à tua pergunta, é qual é a forma que o Audition usa para fazer o rip de um CD. Sei que depois de ter o som num ficheiro digital pouco há que não lhe possas fazer e com excelente qualidade. Mas a questão é mesmo essa, o Audition foi concebido como um editor de som, ou seja, algo que permite manipular ficheiros de som ao mais alto nível: misturar canais, transcoding de formatos, up/down sampling, etc. Ou seja, depois do som estar num qualquer formato digital o Audition é fantástico para o alterarmos da forma que quisermos pois é um editor de som. Já o EAC foi criado exclusivamente como um extractor (um ripper) com a única preocupação da precisão nessa tarefa. No caso do Audition não sei quanto detalhe foi colocado nessa funcionalidade que, claramente, não é a função principal do programa.

Na internet não consegui encontrar sequer informação de quais a opções de ripping que o programa tem.

Re: EAC - Exact Audio Copy [Tutorial]

Caro Skywatcher, na realidade, o post que fiz não fala sobre opções de importação mas sim às de exportação de ficheiros. Fica pois a pergunta anterior, do Pavarotti, sem resposta.

Já agora só uma pergunta:

Como tenho o Adobe Audition tenho extraído as músicas com ele. Será um bom programa para "ripar" cds ou este EAC é melhor?

e passo a palavra.
