VoiceNotes are cool but they could definitely use some added functionality. A few notes.
-File size on e-mems. Longer recordings (1hr+) can easily fill up an entire e-mem, or worse, be larger than most entire e-mems and are never actually able to get written to anything. Given that these are supposed to be highly compressed files, it seems like they should be smaller. Maybe a cap like photo size is in order.
-The ability to record an entire room. Right now a voicenote can only record when someone speaks directly into it. The ability to "wear a wire," while having some pretty serious IC implications, could also make for some very cool interactions and data gathering. It was suggested at one point that this might come in the form of a microphone attachment but this doesn't seem to have materialized yet.
-Speech to Text. Given that all text on a recording is automatically translated, it would be very cool if there was a 'text overlay' feature where you could read a text transcript of a voicenote recording on an e-note. Right now it appears that the only way to play back a recording is in real time, which is cool, but very time consuming to listen to longer recordings.
One system I have not been able to interact with is the forensics related gadget for analyzing voicenote recordings. However I feel like since all recordings are currently very intentional (re needing to speak directly into the voicenote) this really has very limited functionality at current.
An idea for a countermeasure to jam voicenote recordings might be some sort of high frequency emitter that someone can plant on their body and activate that will nullify any sort of room recording. Imperceptible to the human ear, I imagine it could be useful in all kinds of applications to nullify audio surveillance, cameras included. A potential downside could be a very high battery drain, so powercells need to be replaced on a frequent basis for them to stay functional.
This is all just off the top of my head, but I feel like with these changes VoiceNotes could be a much more robust system and get more use by a wider audience.
