Waveform

The waveform is that of track 3 “Take Five”. As for the vinyl Analogue Productions (Ed 2), The waveform shows that there is neither excessive compression nor saturation but a quite low recording level.

Spectrum

Next picture shows the frequency distribution over the Track “Take Five”. Interesting characteristics on this curve are:

1. The level (Green) above 10 kHz is almost 5 to 10 dB lower than Ed2 Vinyl AP and equivalent to Ed1.
2. There is a progressive decrease in level above 15 kHz (Yellow) without noise up to 30 kHz.
3. There is frequency peak above 25 kHz (Red) probably due to a parasite generated by an analog electronic device.
4. The noise level above 30 kHz (pink) increases, natural increase of DSD technology.

Spectrogram

• The yellow arrows show the progressive decrease in frequency above 15kHz (in Yellow in the previous picture).
• The red arrows show a thin line confirming the pick noise above 25 kHz (in Red in the previous picture).
• The pink arrows show the rise in noise level above 30 kHz (in pink in the previous picture).

Waveform

The waveform is that of track 3 “Take Five”. The waveform clearly shows a louder signal and some clipping (see the zoom below). The waveform is also in inverted phase (The green area should be on top and not below the waveform).

Zooming on the audio signal show many clipping (in yellow). The signal, which is beyond the capability of the SACD, is simply cut off. This defect produces strong harmonics in the high-frequency range.

Spectrum

Next picture shows the frequency distribution over the Track “Take Five”. Interesting characteristics on this curve are:

1.      There is a collapse in the signal level after 22kHz (Yellow) which is not present in the Ed3 SACD Analogue Production , can be a filter to reduce noise after 22 kHz (same limitation of the CD).

Spectrogram

• The yellow arrows show the cut off at 22kHz (in Yellow in the previous graph).
