Error Correction Tests
In the following tests we examined the error correction capabilities of the Duet LSC-24081 when reading recorded CD-R's.
- EAC CD-R Test Disc
|Errors total||Num: 174938590|
|Errors (Loudness) dB(A)||Num: 853104||Avg: -25.1 dB(A)||Max: -2.1 dB(A)|
|Error Muting Samples||Num: 922088||Avg: 17.3 Samples||Max: 3584 Samples|
|Skips Samples||Num: 356||Avg: 43.9 Samples||Max: 2934 Samples|
|Total Test Result||47.2 points (of 100.0 maximum)|
Duet LSC-24081 gave back many errors. Most of them resulted to output muting. This means that the errors were uncorrectable, or even skipped. The performance is low and the average score is only 47.2 points out of 100.
- ABEX TCD-721R
|Errors total||Num: 1354115|
|Errors (Loudness) dB(A)||Num: 57624||Avg:-70.2 dB(A)||Max: -8.4 dB(A)|
|Error Muting Samples||Num: 4430||Avg: 3.0 Samples||Max: 1149 Samples|
|Skips Samples||Num: 10||Avg: 16.8 Samples||Max: 48 Samples|
|Total Test Result||65.1 points (of 100.0 maximum)|
This time the drive gave less errors than previously, but the score is still lower than average. The Loudness errors reached the -8.4 dB(A) and had an average value of -70.2 dB(A). In addition, 4430 samples were muted.
- ABEX TCD-726
The drive gave an average of 76 points out of 100. This time the "errors loudness" occurred were less, and their average level is low, -39.7dB(A) average. No samples were muted but 6 of them were skipped.
|Errors total||Num: 43|
|Errors (Loudness) dB(A)||Num: 64||Avg: -39.7 dB(A)||Max: -14.3 dB(A)|
|Error Muting Samples||Num: 0||Avg: 0.0 Samples||Max: 0 Samples|
|Skips Samples||Num: 6||Avg: 538.0 Samples||Max: 588 Samples|
|Total Test Result||76.0 points (of 100.0 maximum)|
