CD- Check
In this test, we use the CD-CHECK media specially prepared by Digital Recordings (see below for description). On the pressed disc, damage was created, as shown in the picture:
The green line on the graph represents the reading speed of the audio disc.
By comparing the disc damage and read speed fluctuations, you can analyze the drive's
response and time to detect damage to the media. With the drive time, the SR / EC is reduced.
Another test to evaluate the efficiency of the SR / EC mechanism is to use the DAE Quality program. The test consisted of reading a damaged audio disc at the maximum available speed, bypassing the programmable error correction mechanism. The test ran smoothly despite the odd shift of data on the screen with the read graph.
Exact Audio copy (EAC)
EAC can read audio discs in two modes: secure and burst. In the first case, the extraction process is slower, as the program tries to recognize and correct errors arising while reading the disc. In the second case, EAC omits built-in error correction procedures, making the reading more efficient, but the quality of the ripped audio material depends to a large extent on the error correction mechanism of the device. Below you will find screenshots from the EAC program, made after reading the path in a given mode (burst / secure).
Read audio in secure mode:
Read audio in burst mode (continuous):
Read protected audio discs.
To verify that the drive is working properly with secured audio discs, we have used the following discs:
Summary:
Audio testing shows that the drive has a decent mechanism for reading audio data. The offered read speed is not large, but the correction is very good. Decent results (as for the BluRay drive) were achieved in the CD Check and DAE Quality tests. The CDS-200 and Key2audio CDs can be read without the use of decryption programs.
