Topic: RockBox Settings

[darktrain]

As long as this rockbox segment is fired up again, when i am searching around rockbox, i am having a little difficulty locating the REP for the H3XX, maybe i am overlooking it but any help would be great.

Ok, so the volume doesn't matter? (mine's currently at -25db)

My AGC Safety says 4db even though I set it for 24db...?

Volume doesn't affect the recording at all, only gain does.

You will notice that the gain displayed (max. gain?) by the AGC Safety line will fluctuate depending on what you set your gain to.  I thought that there was a way to set it to a fixed value, but with the recent testing I've been doing I noticed that it just fluctuates, dependent on the gain setting your using at the time.  I'm trying to better understand this function at the moment as well. 

All of the negative comments about tapers using AGC on recorders go out the window with AGC Safety.  All it is going to do is keep you from clipping if you set your initial gain too aggressively.  It would have been nice if my old pcm-m1 had the AGC Safety feature instead of the useless AGC that it came with (useless for live recording, that is).

Well, I just said ouch because I can rub people (with my cluelessness) the wrong way....I just didn't expect it to be you!  So, it will start a new file no matter what?  I thought there was some setting that needed to be engaged for a new file to be started once the file limit was reached?

Seriously Petur, you have no idea how big of a rockbox fan I am.  It has saved me from taking the plunge into all-in-one box land and spending a fortune on that rather than on mic capsules!

Shaggy-
I've been guilty of the same thing on probably more than one occassion (trying to shed a little light to someone asking about a feature of the Rockboxed iRiver and mispeaking on the issue).  I can understand how frustrating it must be for the developers when they see misinformation, but I also believe that Petur knows the appreciation and passion that many of us share for the Rockboxed iRiver.  +T's all around

don't rub it to hard the other way too

Maybe I've been a bit too hard this week, it's been kinda busy
But you guys converted me to a taper and I'm loving it - recording every gig I go to...

more tickets?

On the AGC issue: 
Arni99's post on this thread:  http://taperssection.com/index.php/topic,85618.msg1140063.html#new  clears things up.
I just need to see if the 'AGC Max setting' is only a function of the REP, or is in the standard build.  I don't remember having the option of setting the max gain setting on the standard build I was using the other night, but I may be wrong.

[Gawain]

It's on the standard build aswell, I have 25.april.2007 build in one unit and it has it.

P-Man: I'm pretty sure all of the questions you have asked thus far are addressed in the FAQ.  Honestly, as several others have already suggested in this thread, please read it: http://taperssection.com/index.php/topic,73139.0.htm

By continuing to ask questions that are already addressed in the FAQ, you are implying that your time is in fact more valuable than ours.

Sorry dude. I did read that actually. I didn't understand it all so I asked for clarification and help. Relax.

I taped my show last night and the volume on the recording is low. Is there a way to make it louder next time? I set left and right gain to 20db.

Is this a trick question 

[P-Man]

No, I was just wondering if there was a way to make it louder while recording. Do I just have to do post editing?

[Chuck]

You can make the recording louder, by rising the gain to a value over 20db.

[petur]

... but setting gain above 20dB will also introduce more noise.

So if you find yourself with low volume recordings at +20dB, you should consider getting more sensitive mics and/otr a mic-amp

[P-Man]

Would setting gain at 15 be better, then amplify after?

[petur]

no you can still use the iriver gain, but after 24dB it will use the decimator to increase gain (digital gain).

However, this is not that bad since the decimator uses the 24bit signal from the ADC, and the actual recording is 16bit, so in theory this is better than post-processing.

The issue at hand is that the signal becomes noisy because of all these amplifications, which is why I made the above suggestions.

So if you're not going for better mics or a mic-amp, increase gain on the iriver....

[P-Man]

I own Church Audio mics and battery box. I need more than this?
