Sound Demonstrations for the presented EEG data sonification techniques

Table 1: Audification of EEG data (2 electrodes, 3 subjects and all 3 conditions). Besides the dominating noise, pitched spikes can be heard

File/Track:	S1:: EEGr: Fp1, T5, Fp1/T5, speech: Fp1, T5, Fp1/T5 , pseudo: Fp1/T5 S2:: EEGr: Fp1, T5, Fp1/T5, speech: Fp1, T5, Fp1/T5 , pseudo: Fp1/T5 S3:: EEGr: Fp1, T5, Fp1/T5, speech: Fp1, T5, Fp1/T5 , pseudo: Fp1/T5
Description:	Audification of EEG Data for two electrodes (Fp1 and T5) for subjects S1, S2 and S3
Duration:	1 s

Table 2: Sound examples for Spectral Mapping Sonification of EEG data, for pseudo speech and speech condition in a sequence with a short gap in between of 2.5 s in real-time.

File/Track:	delta=0.4, [0-30Hz], left: T3,T5, right: T4,T6 S1 S2 S3 S4 S5 S6 delta=0, [0-30Hz], left: T3,T5, right: T4,T6 S1 S2 S3 S4 S5 S6 delta=0, [0-30Hz], left: F7,F3,T3,C3,T5,P3, right: F4,F8,C4,T4,T6,P4 S1 S2 S3 S4 S5 S6
Description:	Spectral Mapping Sonification of EEG data
Duration:	about 4 s

Table 3: Sound examples for Distance Matrix Sonification of spectral vectors. High-pitched loud tones indicate long-range frequency selective couplings

File/Track:	frequency range 8-20 Hz, subjects: S1 S2 S3 S4 S5 S6
Description:	Distance Matrix Sonification for concatenated datasets for the pseudospeech and speech condition. A noise burst separates the two parts
Duration:	5 s

Sound Example: Ex-DiffSon-1, Differential Sonification for Example shown as spectrogram
Table 4: Sound examples for Differential Sonifications

File/Track:	pseudospeech-speech (1s): S1, S2, S3, S4, S5, S6 same with higher threshold (1s): S1, S2, S3, S4, S5, S6 speech - EEGr (1s): S1, S2, S3, S4, S5, S6 pseudospeech-speech (4s): S1, S2, S3, S4, S4, S6
Description:	Differential Sonification of EEG data
Duration:	1 s and 4 s
