DAE Error Recovery
The DAE function of PlexTools Professional can detect uncorrectable read errors.
This detection is based on the C2 flag that is read together with the audio data. It is
impossible to correct these errors, but PlexTools Professional offers a choice of
smart strategies that attempt to recover the original data. These strategies consist of
combinations of re-reading the data and changing the read speed. Depending on the
type and severity of the damage, each strategy will give a different result. You can
try out the different strategies and options in order to minimize read errors and
achieve the best results. The goal is fast DAE with no read errors.
•
1. Report Errors only (no recovery action)
: This strategy can be used when the
source disc is error-free or error correction is not necessary.
•
2. Reduce the speed upon error
: When uncorrectable errors are found, the
damaged area will be read at a lower speed in order to find an error-free reading.
•
3. Read again upon error
: When uncorrectable errors are found, the damaged
area will be read again for a number of times (retries) at the selected speed in
order to find an error-free reading.
Allow Speed Down
: Optional choice to achieve better results at lower speed.
•
4.
Recover the best sector (least errors)
: When uncorrectable errors are found,
the damaged area will be read again for a number of times (retries) at the selected
speed. When the errors stay, the sectors with the least errors will be used to
reassemble the original data.
Allow Speed Down
: Optional choice to achieve better results at lower speed.
•
5. Recover the best bytes (least errors) per sector
: When uncorrectable errors
are found, the damaged area will be read again for a number of times (retries) at
the selected speed. If the errors remain, the bytes with the least errors will be
used to reassemble the original data.
•
6. Error Log
: This option allows the complete logging of all details of the error
recovery.
Audio Format Options:
•
PCM (wave)
: Select sampling options to be used during extractions, including:
The number of samples taken per second
The size of the samples
The sound mode (stereo or mono) to be used during extraction.
•
MP3 (Windows encoder)
: Select this option if you want to extract audio tracks
to MP3 format using the installed Windows encoder. Availability, number of
options, and choices for quality depend upon the installed encoder.
