audio_vocalics

OpenSMILE acoustic features extracted from each participant's microphone audio during the Minecraft missions; each row is one analysis frame. Beyond the identifying columns below, the table has one column per OpenSMILE low-level descriptor (LLD) from the ComParE feature set (e.g. `f0final_sma`, `jitterlocal_sma`, `shimmerlocal_sma`, and the `audspec_rfilt_sma[*]` and `mfcc_sma[*]` families) together with their first-order delta (`*_de`) coefficients.

Column descriptions
group_session
The group session the audio is a part of.
station
The iMac that the participant was stationed at.
minecraft_mission_id
ID of the Minecraft mission during which the audio was recorded.
id
Sequential ID of the frame.
timestamp_unix
The Unix timestamp of the frame.
timestamp_iso8601
The ISO-8601 timestamp of the frame.
frame_time
The frame time in seconds.
f0final_sma
Smoothed fundamental frequency (F0) contour.
voicingfinalunclipped_sma
Voicing probability of the final F0 candidate.
jitterlocal_sma
Local (cycle-to-cycle) jitter in F0.
jitterddp_sma
Differential frame-to-frame jitter (DDP).
shimmerlocal_sma
Local (cycle-to-cycle) variation in amplitude (shimmer).
loghnr_sma
Log harmonics-to-noise ratio.
wave_rmsenergy_sma
Root-mean-square frame energy.
wave_zcr_sma
Zero-crossing rate of the time-domain signal.
