So I been analyzing the soundtrack quality with "
MP3 encoding norm, if not variable, are 128/192/256/320KB.
Out of 161 tracks:
15 are <128k -- this is the worst MP3 quality
93 are 128k -- this a low quality MP3
16 are poor variable of 139/166k
13 are 192/256k -- this should be considered the minium MP3 quality to keep a ratio of size/quality
14 are quality variable of 315/319k
10 are perfect 320k -- best mp3 quality
So in that first picture it's a 128k, you can see the deep of sound cut at around 16K, the HiFi norm is 20K.
The second picture is a 320k, here we can see the deep is over 20K, the sound have more volume and range, quality.
In short: 128k ~16K | 192k ~18K | 256k ~20k | 320k >20K
Some of the licensed tracks can even be pretty poorly encoded, here supposed 192k when in fact poor 128k.
So here the balance with quality/size. Actually the soundtrack weight 600MB. A 3min sound in 128k is about 3MB when a 320k is about 8MB. At 320k the soundtrack size could almost triple or reasonably at 256k double.
My 2-cents, DPC should double check the sound quality, standardizing it, get better sources if needed for consistency.
