Waveform

Like the Ed2 Vinyl double , this edition has a very good dynamic with DR15. You can notice fine peaks representing the guitar attacks as for the Ed2 vinyl double.

Waveform Ed6 : DVD Stereo

Spectrum

The curve represents the average frequency distribution over the sample “Before You Accuse Me”.

The two curves are superimposed except in the green zone where the bass is lower by one db, and in the yellow zone above 10 khz where the treble is a little lower. The purple area shows the conversion from 44.1 kHz master to 48 kHz.

Spectrogram

Spectrogram is another representation of frequency versus time of a track. For each channel (right and left), horizontal axis represents time, and the vertical axis represents frequency. The amplitude is represented by the intensity (brightness) of the color of each point in the image.

The yellow arrow represents the normal collapse arround 20 kHz (sampling frequency at 44.1 kHz of the master). The green arrow shows the limit at 24 kHz due to the 44.1 to 48 kHz conversion. The white arrow shows no signal above 24kHz (black lines).

Waveform

This edition is very dynamic, we can see many attacks of the guitar that give this dynamic rendering. We can also notice that the reinforcement of the subwoofer (LFE channel) is not present on all the tracks.

Waveform Ed7 : DVD 5.1

Spectrum

The curve represents the average frequency distribution over the sample ” Before You Accuse Me “. The 6 curves represent the 5.1 signal (Right, Left, Center, LFE, Surround Right, Surrounf Left). The yellow area shows the lower level in the low frequencies of the surround channels below 500 Hz. The Green area shows the limit à 20 kHz for Right, Left, Center, Surround Right, Surrounf Left. It can be observed that there is no signal for the LFE channel in this sample.

The yellow arrow represents the normal collapse arround 20 kHz (sampling frequency of the master at 44.1 kHz). Above 20 kHz , there is no signal (black area).

The green arrow represents the limit of the LFE channel arround 120 Hz.
