Feature request: Signal recording

[Anyeos]

The idea

As Audacity is for audio signal recording It will be very helpful to have the hability of recording the signal for future use.

For example

I need to analize a signal that is more than one second long but I need to look at the microsecond level detail on all the one second period.
Actually I can do something like that just increasing the timebase and using zoom. But it is not possible to make a detailed time analysis because the samplerate is low.

I suggest export the signal as raw format or if it is possible as a PCM or WAV with corresponding headers. Maybe some limitations may apply.

Early proposal

A button to record a few megabytes of signal on memory (the limit can be choosen on configuration). Next the recorded signal can be exported to disk.

The first proposed format maybe RAW (as is) with some header that specify the samplerate, bit depth and some other things.

Suggestions and brainstorming are welcome
