248 surround files against 124 unique sounds is exactly two files each.
That division is done here. The field names eight channels in two tiers of four — Lo of L, R, Ls and Rs; Hi of Lh, Rh, LSh and RSh — and it does not say how those tiers map onto the two files, so this page does not guess. What it does state plainly is that the stereo edition ships with the 3D one, and the delivery objects bear it out: the surround package carries the stereo package’s own five archives inside it.
At a Glance
- 248 files, 124 unique sounds Exactly two files per sound — the division is computed here
- 88.4 GB across 248 files About 356 MB per file. The stereo edition is 22.2 GB across 124 files, about 179 MB each — both divisions computed here
- 88.4 and 22.2 make 110.6 And 248 files plus 124 make 372. Both of the field’s combined figures are the two editions added, and both sums are checked here
- The Features line crosses its own rows It pairs 248 surround files with 110.6 GB. In the description table, 248 files are 88.4 GB and 110.6 GB belongs to the 372-file row that includes stereo. Both readings are printed here
- Eight channels, two tiers of four Lo: L, R, Ls, Rs. Hi: Lh, Rh, LSh, RSh — the field’s own track layout, printed as it stands
- Three animals in the prose, seven in the keywords The prose names woodpecker, raven and crane. The keyword list holds seven animals in all, adding cricket, deer, owl and an entry spelled WOLVE — four the prose never mentions
Content & Detail
Autumn is the short window where a forest stops being one continuous sound. The field puts it as a season sitting between the density of summer and the silence of winter, and the material follows that reading: half-bare branches, leaf beds on the ground, and cranes it describes as migrating.
