Offset strength (offsetProc.m
)¶
Similarly to onsets, the strength of offsets can be estimated by measuring the
frame-based decrease in logarithmically-scaled energy. As discussed in the
previous section, the selected rate-map parameters as listed in
Table 24 will influence the offset processor. Similar to the onset
strength, the offset strength can be constrained to a maximum value of
ons_maxOffsetdB = 30
. A list of all parameters is presented in
Table 26.
Parameter | Default | Description |
---|---|---|
ofs_maxOffsetdB |
30 |
Upper limit for offset strength in dB |
The offset strength is demonstrated by the script DEMO_OffsetStrength.m
and
the corresponding figures are depicted in Fig. 30.
It can be seen that the overall magnitude of the offset strength is lower
compared to the onset strength. Moreover, the detected offsets are less
synchronised across frequency.
