Excellent result with slightly lower noise than on direct playback via the Tascam.
This is the same test as shown played back on the Western Digital player. Note that the -20dB distortion figure is lower here than on the WD player, but still higher than the -49dB figure obtained on direct playback from the Tascam. This seems to indicate that excessive quantising errors are common on so-called 24-bit A-D converters. A very acceptable result nevertheless, and within Lindos Grade A (ignoring absolute levels).
Whistles were noted audibly on the sweep high frequencies - a common problem with computer audio cards indicating a beat with the sampling frequency. They were not noted on the Tascam replay or Western Digital replay. |
