What is CDLector?

NOA’s CDLector is a mass CD-ripping system capable of handling up to eight parallel drives. Designed to extract audio from CDs into digital audio objects with perfect control over interpolation, it delivers optimal results even for heavily damaged items. 

CDLector prompts you to insert the right carrier into the drive with automatic opening/closing of the corresponding drive in automatic mode. Alternatively, the system can use the carrier barcode to fetch the corresponding metadata item to be digitized. As it is harder and harder to get reliable CD ripping drives with proven C2 behaviour, NOA delivers specifically selected CD drives which are proven to get best results in interpolation quality.

CDLector requires a jobDB or mediARC environment.

CDLector includes algorithmic analysis as well as advanced metadata retrieval, and supports four read modes:


Reads all sectors up to 64 times and will only move on to read the next sector if it has an exact match between two read results (recommended for archives).



Reads in Archive Mode until a C2 error is detected. From there on it switches its reading mode progressively to C2 mode and upon further failure into Burst mode, annotating the read mode changes. The last mode is kept until the end of the current carrier, switching back to Archive Mode on the start of the next.



Alternate Mode starts in Archive Mode and switches into burst Mode upon uncorrectable read errors, annotating the read mode change until the end of the current track. On the start of the next track, it switches back to Archive Mode automatically.



Can be used for CDs when no other method of grabbing will lead to a result. Burst Mode is a single-pass mode with the highest speed (typically 28x) and no transfer security, except for algorithmic traces.
