Recording Enhancements Pack

No, I've been very busy and will be for a few days..

Is there a 'how to' for the REP anywhere?  I can't work out what that graph is above the right hand histogram. And I could do woth some guidance on the best recording levels to set the inputs at....am I right in thinking that 28 dB gain might be best?

It's a wonderful tool though and turns out great sounding files. Thanks.

I've put the font stuff with the latest AGC/histogram patch.. works fine here..

Good stuff...unfortunately this won't compile for the H140! 
It doesn't like your lcd_set_foreground(global_settings.fg_color); not one little bit!

I changed it back to LCD_DEFAULT_FG and then it compiled but it hangs when you try to use the line in! So seeing as I'm still feeling lazy, I think I'll just carry on using my humble little B/W patch!

There is no manual for these functions as far as I know (as it isn't part of the official build yet) and I know very little about it as it is Vinylivo's work.

All I can say is, the graph you mention tells you about the balance of the input.

There is no perfect level, it just depends on what you are recording and how loud it is. As a general rule you need the level as high as possible without it clipping.

Have a look at the tracker info on the AGC patch (Link in post#1) for more info.

My guess is the fg_color is defined for H300 only..

I do not know much about programming, but I was able to patch the latest bleeding edge source (late 20060512) with the AGC patch petur put up on the tracker. I was not (since I don't know what I'm doing) able to apply the histogram patch without errors.

Just an FYI.

I'm thrilled to have AGC and optical! THRILLED!

[petur]

I wonder why AGC is usefull when recording digital? Isn't it the ADC/preamp that needs tweaking when clipping occurs?

Unless you mean that with the AGC patch on the latest version, you can do digital recording and analog recording with AGC...

[dwonk]

FYI, there is no control of gain by the recording device when receiving digital information from a outboard A/D (the H120 is essentially a bit dump at this point) .  Only the A/D's gain will increase/decrease the gain/signal to the bit dump.

[Davide-NYC]

I meant AGC for line-in is crucial for my field applications (just an external mic for now) and optical recording I've only been using 'in the studio' to do transfers from old DAT tapes etc.

So even though they don't get used simultaneously, I am still THRILLED to have them both operational. RockRivers are the best!

So what about the Histogram patch? I know it's just eye candy, but it's mad cool.

D :-)

[petur]

A short warning that amiconn is writing an audio driver or at least moving the gain setting to a lower level. This will break the AGC patch again.

Just so you won't be surprised when this happens

[petur]

AGC patch updated, please test....

[Davide-NYC]

Patched the bleeding edge CVS and 'make' a normal build no problem.
I'll do some field testing with the line-in using an external stereo mic tomorow.
The patch breaks the simulator. Is this normal?
Looks good so far! Will report back after doing some recording!
Thanks!

euh... no... will check tonight. As this wasn't meant to be committed directly I didn't check on anything but h300 (which means also h100)

[renho3k]

recorded another show last night with the set up and it worked beautifully. i've recorded a few shows before but they were mostly acoustic where clipping wasn't a major issue but this time it was a nice, loud rock concert. oh blessed is the remote recording feature!! ditching the MD and never looking back!

thanks again for all that made this possible.

Would it be possible for the AGC to write some kind of log when which amplification was used? That would be very useful (e.g. when you set the AGC to safety to get no clipping and want the whole audio on one level later when editing)
