The Dolby Channel Check TrueHD dominates this page — and it comes in two formats that are worth distinguishing. Both run 94 seconds and cover the same channel routing test — the only difference is the audio codec. DD Plus 7.1 at 120MB, TrueHD 7.1 at 164MB. 57,570 downloads for DD Plus, 58,800 for TrueHD. Essentially the same number — unusual for two files with different codecs on the same page, where usually one format pulls ahead clearly. The Dolby Channel Check TrueHD version edges ahead, but only just.

Spheres V1 and Spheres V2 are both on this page, which is useful context for anyone who’s come from the Spheres article elsewhere in the library. V1 runs 31 seconds at 34.5MB (DD 5.1) and 70.6MB (TrueHD), V2 is shorter at 25 seconds but the TrueHD version is larger at 93.3MB — higher bitrate for a shorter clip. The lossless TrueHD versions pull significantly more downloads than the 5.1 ones: 66,430 vs 52,260 for V1, and 57,150 vs 38,250 for V2. V1 lossless is the most downloaded file on this page.

Sports is the outlier — at 152 seconds and file sizes of 318MB and 378MB it’s by far the largest file in the entire Dolby section. Both versions are mkv only, which is unusual for this section where m2ts is common. Downloads are lower at around 22,860 and 29,910, which makes sense given the size — it’s not a quick test file. If your connection and storage allow it, it’s the most complete stress test of the five on this page.
