The waveform represents all the tracks of the album.
This edition is very dynamic, we can see many attacks of the guitar that gives this dynamic rendering. As opposed to the Ed4 CD version which is a little compressed.
The Spectrum allows to check the tonal balance of the music (balance between treble, medium and bass sounds) and to detect process that may have been carried out during the recording, the mixing, mastering or manufacturing phases. It is also possible to detect frequency interference issues.
The curve represents the average frequency distribution over the sample “Before You Accuse Me”.
The interesting features on this curve are the following:
- The two curves are superposed up to 10 kHz.
- The treble level (Ed1 Vinyl) above 10kHz is one or two db higher (purple area) than the Ed4 CD
- The high frequency cuts at 20kHz due to the digital master. This is noise (yellow area) on the Ed1 vinyl due to the analog noise of vinyl, as opposed to the cd version (green area).
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 reveals the limit around 20 kHz due to the mastering. Beyond 20 kHz (black arrow), there is noise or distortion due to the vinyl playback method.
