Details

If its possible to access the microphone input during playback, it
could be used to measure environmental noise to increase or
lower the volume accordingly. This would be extremly helpful
when using the Recorder in a car, so you don´t have to adjust the
volume manually at different speeds.

Damn - I hoped I was going to be the first person to think of
this - It really is a cracking idea and would make a great
feature.

the only problem with this over the car speakers would be that it would adapt to its own growing volume and will not stop until it maxes out. Great idea for use with headphones in loud places though.

I had the same idea for listening over headphones. When I walk with the player I must adjust the volume very often because of the ambient noise.

I think that there must be some kind of very sophisticated filter for the ambient noise measurement. It should:
- remove the noise made by the physical contact of the player (in your pocket etc.)
- remove the played sound (so it will be usable also with loudspeakers)
- etc.

Just wanted to throw my 2 cents in. I think it would be great. Guess it would only work on players with a mic.

another intresdting branch of this would be a (possibly voice-cued) attention mode, that could drop, or pause, when it detects any significant noise...
