I have a fairly large collection of audio/video bootlegs recorded at live performances by various artists. The recordings all come from very different sources and people through decades, and all of the recordings in the collection are just audio/video files. Since the collection is large, the total running length of the collection is probably hundreds hours.
The quality of each recording varies: some of the recordings sound excellent (let's call it "10"), but some of them sound more like noise ("1") remaining a point of interest for a particular artists collector. Let me say this way, by "quality" I mean something the way "how good" it looks and sounds to me or anyone else (and not the audio/video codecs settings the recordings are encoded or compressed with; and not how a particular artist performs -- it's a matter of personal taste, not audio/video quality). When I started collecting bootlegs more than a decade ago, I remember, I could find characteristics for many of them like "Quality: A+" (really nice), or "Quality: B-" (not that bad, but makes interest to a collector.)
For example:
if a live recording sounds as if it is recorded in a studio, then it might be evaluated to "9" or even "10" (regardless if either a lossy or a loseless audio-codec used);
if a recording shows up noticeable visual VHS artifacts like blue/red/green stripes (just because the recording was recorded on a tape), but the overall picture is pretty good, it might be evaluated say to "5+" up to "7";
if the recording sounds very "bassy" and low frequencies heavily prevail the high ones, it might be evaluated to "3-" since the audio might be considered very low quality, etc. If such a thing exists, I guess it might also to be applicable for audio, video and images;
and more...
Is it possible to analyze a recording in a software way, not listening/viewing to it, to "determine"/"evaluate" its subjective quality?
This question looks pretty much similar to Analyzing the quality of a music track (and probably audio quality evaluation ) , but can't really tell how close it is.
(Please note I have zero knowledge in this area, may use wrong terms and may ask something unreal. The only reason I'm trying to find it out is editing the files metadata by putting the "quality" tags into it, thus evaluating the average/overall quality of the entire collection not spending weeks of listening or watching to all of the recordings regardless hardware I might use. Also not sure if the question is better to ask at Software Recommendations or Sound Design though.)
