Unlike the previous tours, the community tours are recorded with lightweight handheld equipment and edited using a new technique we are still developing, which does not capture sounds appropriately (yet). We are still working on how to produce high quality tour audio with the community tour creation techniques we are developing, so we appreciate your patience while we continually improve the community programs.
As with everything else in BitGym, we highly value your feedback with community tours as it grows and develops in all ways as we work on it.
There are about three classic tours which also do not have audio just due to how they were shot and produced. Note that tours which intentionally do not have nature sounds should indicate this in the workout menu by not having a nature sounds toggle.
