For: People inspecting continuous seismic recordings
Worth noticing: It rejects separate channels, gaps, and overlaps; playback audio is converted to mono 16-bit, 8 kHz WAV.

Field notes

The page separates analysis from listening: waveform and spectrogram plots are described as using the original recording, while playback audio is peak-normalized and converted to mono 16-bit, 8 kHz WAV. Users can bookmark a point or selection, add a title and notes, and export or import project JSON. The stated upload ceiling is 256 MiB, alongside limits on sample count and record count.
