Update: AnalysIR Auto-clean feature for IR signals

Here is a screenshot showing the new automatic signal cleaning feature in AnalysIR. You will notice in channel 2 (yellow & red) where I have overlaid the recorded signal from CH1 (green) on top of the cleaned signal in CH2 (yellow). The green & red signal is the recorded signal & the yellow signal is the ‘cleaned’ signal.

The reason for the signal degradation in the first place is due to the way all IR receivers work. Typically, marks will be shorter and spaces will be longer. Also, weak IR signals will also alter the duration of marks/spaces.

Combined with AnalysIR’s sensitivity setting for decoding it is possible to rebuild a perfect signal from a really poor signal.

With this new ‘Bonus Feature’, we can export almost perfect signals from AnalysIR and re-import the exported signal to compare against the original recorded signal. This will be a great benefit when designing IR devices or circuits.
