Six quick steps to Ripping:
CD Ripper in Detail
CD Ripper comes preconfigured with two advantageous Internet technologies:
by comparing results from other peoples rips, a match to their rip is a 100% certainty it was without error, no
other secure ripping method can get this close to verifying error free rips. Once a month AccurateRip will request to send your results to help populate the database.
PerfectMeta™ online meta-data from AMG, GD3, SonataDB (Classical), MusicBrainz and freedb simultaneously to
retrieve track names and high resolution Album Art [dBpoweramp Reference required]
Meta data comprises identification fields, such as album, artist, album artwork, etc and is embedded into audio files in their ID Tags.
PerfectMeta™ uses 5 Internet meta data providers simultaneously, this allows any inevitable errors, such as spelling mistakes to be self corrected. In addition, there are 100's of internal rules to ensure that the metadata returned is consistent across discs & providers. PerfectMeta offers the best metadata solution obtainable today.
PerfectMeta does not just use one premium (pay for use) meta provider, but three! All Media Guide, SonataDB (classical database) and GD3, in addition to MusicBrainz and freedb.
Meta data is retrieved automatically when an audio CD is inserted, pressing the Meta button retrieves meta data a 2nd time, if PerfectMeta was used it is possible to see its workings by clicking Review Metadata, or make self corrections (on the Review page, click on any red item to set to it, click a metadata provider button, at the top to override with all metadata from that provider).
Metadata can be typed manually on the main page by selecting a track and pressing F2, after typing press enter to move onto the next track. Clicking the Meta tab (next to Encoder), lists all Meta data items for a track or the whole disc. Items shown in gray are excluded from being written to the ID-Tag (click Options >> Meta Data & ID Tag 'Options' to view exclusions).
The Compilation checkbox allows each track to have a different Artist, Year and Genre. Ordinarily with no tracks selected typing into the Artist box at the top changes the artist for all tracks, however if compilation is selected selecting one track highlights the artist box in blue to show that only one track artist is being edited, pressing enter moves onto the next track.
Album Art is automatically retrieved from the
internet, its size depends upon the source (at the time of writing
up to 1000x1000 from GD3 and Musicbrainz, 250x250 from AMG). If artwork is not of a
suitable quality, missing or wrong click Choose Art
and the Internet is searched for artwork.
It is also possible to add album art manually by clicking + >> Load (from file), Paste (from Clipboard) or Acquire (from Scanner). Note when adding new art with +, the old art is not removed, it should be removed with '-' before adding new.
The final maximum album art resolution is set under Options >> Meta & ID Tag 'Options' >> Maximum Album Art Size (defaults to 750x750 for best player compatibility).
Clicking on the album art displays at full resolution.
Multiple artworks can be added and given a different description (such as Back Album Cover).
Ripping status is shown for each track, informing progress and when secure ripping the secure status of a rip.
Burst ripping method has no error correction, ripping is done in one shot.
Ripping and encoding are
done at the same time. The light grey bar on Rip Status shows the read position, whilst the darker grey bar is the
encoding position. dBpoweramp Reference allows multiple CPU systems (such as dual core) to encode two or
more tracks at the same time.
Secure Ripping [Reference required]
Secure ripping uses multiple passes to identify and correct errors, possible display values are:
First pass, if matches AccurateRip further ripping is not required.
Third pass, the blue highlight indicates that a new error (previously concealed on a previous pass has been detected)
After passes have completed then frames with possible errors are re-ripped multiple times. The red line shows the error position within the track.
The red highlight shows that frames could not be recovered whilst ripping, an insecure rip.
After ripping has completed the audio is passed onto the chosen encoder. dBpoweramp Reference will use multiple CPUs if present.
The rip is 100% error free, confidence of 12
indicates it matches 12 results from other people, even a confidence of 1 is enough to ensure an error free rip as long as it was not yourself who submitted the first result.
Again the rip had no detectable errors, but this time the CD is not present in AccurateRip's database.
Your ripping result disagrees with 12 other peoples rips, the green i indicates that frames had to be re-ripped, possibly an undetected error has
slipped through. If all tracks except one have an AccurateRip verification, and the confidence (number shown in brackets) is more than one, it is likely your rip has errors.
AccurateRip says your rip has errors, also CD Ripper says it is unsecure.
DSP, Encoder & Meta
Meta data is
saved into the ID Tag of each audio track, from Composer to Record Label.
Selecting the Meta tab lists all meta data, if no tracks are
selected then Global meta data (ie the same data applying to all
tracks, such as Album) is listed under Meta. Selecting a single
track lists items pertaining to the one track. Items shown in light grey are disabled from writing to ID Tags.
Encoder displays the active encoder compression settings.
DSP (Digital Signal Processing) allow audio effects to be applied, example effects are ReplayGain, Volume Normalization, etc (there are more than 20 effects). Effects are performed in a top to bottom order. Specific to CD Ripping:
Track List Columns
clicking on a track list column title (ie Length) allows customization
of which fields are shown in the track listing. Artist, Genre
and Year are only shown when compilation is checked.
CRC shows the checksum calculated from the last rip, a green CRC if a re-rip matches the previous, or Red for miss-match (a sure sign that one of the rips had errors).
The File Name column displays the final filename to be written, if the file exists it is shown in Blue.
Track Technical highlights exotic CDs (such as HDCD or CDs with Pre-Emphasis).
To set the order of columns, remove all check marks and re-check in the order required.
Path and Naming
Path and Naming work together to set the output folder and filename, by default naming dynamically changes depending upon CD:
Normal CDs: \[Artist]\[Album]\[Track Number] [Artist] - [Title]
Compilation CDs: \Various Artists\[Album]\[Track Number] [Artist] - [Title]
Set allows customization of the naming convention.
