Noise volume. This mainly concerns digitalized vinyl records.

The presence and volume of distortions. Scratches on vinyl records,
clipping, etc.

Dynamic compression level. Dynamic compression increases the
loudness, but at the same time reduces the "volume of the sound scene."
I almost always prefer the quietest, but at the same time the most
voluminous version of the composition of all available. Since about 1998,
music almost always published in an overmuch compressed form.

Quality of processing by noise reducers and other "soundgoodizers".
Such processing is often used on new (since 1998) reissues of old (pre-1998)
music. In most cases, such processing is not a pressing necessity, but
merely a tribute to sound fashion, so after such processing, music almost
always sounds worse. I almost always prefer the original old edition to
the new reissues.

How to evaluate sound quality? The best way is comparison. If
a composition was released on different releases (for example, on a single,
on an album, on compilations), then you need to try to find all these
releases and compare the sound of this composition on different releases.
Listening should be combined with visual control of the spectrum analyzer
- this will allow more effective detection of audio files repeatedly
subjected to lossy compression.

The first composition should be calm in all аspects, i.e. not too
energetic, not too aggressive, etc., in order to have sufficient reserves
to enhance these properties in the future.
|
| 2. |
Under the influence of long-acting and unchanging stimuli, emotions
become dull and cease to be vivid, so the properties of music in a
mix should change from composition to composition.
Properties can change both in the direction of strengthening and in
the direction of weakening. The weakening of some properties must be
compensated by the strengthening of others (for example, the weakening
of energy and aggressiveness can be compensated by the strengthening
of melody). If such compensation is not provided, the composition will
sound weak in the given context, even if it is excellent in itself.
|
| 3. |
The properties of music must change without returning to what was
previously heard, otherwise the effect of repeating what has already
been heard will arise - this always sounds weak.
|
| 4. |
Each previous and next composition must allow for mixing, that is,
have initial and final sections that will sound harmonious when
superimposed. At the part of selecting compositions, in order to save time,
only the presence of suitable initial and final sections
is checked, without determining their exact boundaries.
|
| 5. |
If a composition will be mixed with synchronization, then its own tempo
should be close to the tempo required for synchronization.
|
| 6. |
The energy of the music should first increase during the mix, then it
can remain at the same level, then it can decrease, but after decreasing
it should not increase again. Increasing energy after decreasing it
always sounds weak.
