Audacity doesn’t apply effects, filters or corrections when recording.

I don’t know of a way to auto save, but Audacity has Sound Activated Recording. Audacity > Edit > Preferences > Recording > Sound Activated Recording.

Audacity doesn’t make a very good surveillance recorder.

I use that currently. The problem is when it run 24/7 the file would get insane big and is not good to rehear if something happened back then. :confused: So smaler bits with a Time and Date would help a lot to find a incident.

Yes it would.

Audacity doesn’t have time stamps and it doesn’t have progressive updating of storage files. That’s a surveillance recorder.

I too would like an AGC when recording but I doubt it is worth my while to hold bu breath. (-:
If there is any way to help to move this along, count me in.

Right now I am looking into building one in Windows.

This is always a problem when working with amateurs. It makes editing a lengthy and painful process. The real solution is “don’t work with amateurs unless they are willing to learn”. Failing that, ensure that everything is recorded at a low enough volume to avoid clipping, and expect to do a lot of editing. Unfortunately there is no magic bullet.

Plug-ins such as “LevelSpeech2.NY” (Improved "leveling" for speech - #27 by Trebor) and “AGC” (AGC - Automatic Gain Control) can help in some cases.

Note that Windows often provides automatic gain control in the “Sound Enhancements”. We generally recommend turning that off as AGC is killer of high quality recording.

Another alternative is to record with a portable recorder. There are many models available, and they frequently have features like AGC and voice activation. As with computer recording, for high quality recording, it is usually best to switch those features off and use manual editing and compressors in post production.
