Recording Enhancements Pack

[whatboutbob]

Jan, I've mentioned this feature to vinylivo previously, and he sounded pretty open to it...so...*fingers crossed*

[jplumey]

Using a stereo pair of binaural microphones and setting the recording format to mono still records in stereo. Is this by design or would that be considered a bug. I love the pack by the way!

JP: The devs haven't gotten around to working on mono recording.  As such the latest builds have removed the option.

Thanks!

 hey, I just picked up an hp120, installed this pack + rockbox, this is amazing!!!

 thx for putting this together!!!


 I can't wait to test out the recording function

[Mmmm]

OK...new patch and build in post#1 as usual...

I've used Petur's updated AGC patch so there is no pretty histogram or balance meter etc.. but I've never actually used them anyway so it's certainly not a problem for me...It does have the changeable fonts in there too and all that patch fixing that's been going on recently in CVS (not to mention optical recording). 


Edit: hmmm having a bit of trouble getting the build uploaded..my internet connection is playing silly buggers with me! The patch is ok though...

....ok....should work now

Hi.
I just got myself a iRiver iHP140 few days ago after reading about the Rockbox project.
So I have working digital recorder inally.
If minidisk ever had an open firmaware.... So far it seems that I am going to sell most of my MD setup.

I have been reading this tread for almost a day and downloading  patches and trying them out. So I have few questions I did not get answered from readings. Maybe I missed something and the info is here, so sorry to ask it again.

I have installed the latest optimised build from pilot000 (misticriver) as a last try, but still my recording settings does not have Frequency nor Independent  Frames option.
Both are what I think I need. I would like to get the max quality(48kz) recording and edit it with pro software.
So, do I suppose to have them?
The other interest is in AGC. Does using AGC and gain in rec. window give good results?
I shall be doing some testing with my mic-preamp setup, but since there is a lots of excitement about AGC I would like your suggestion.

AND THANKS FOR THE GGOD WORK!

Nope. Frequency and stuff are not configurable. As a matter of fact, those settings are not available on the official build anymore so the 'optimized' build you have must be getting old...

I mainly use AGC as clipping protection, to make sure gain is lowerd a bit when the signal gets louder. No idea how it works otherwise, I suggest you try it.

Oh, and welcome to rockbox

One more thing:
from some old treads like "external mic recording?" there is a talk about setting ADC gain in record setting window.
Is this no more possible?

analog and digital gain have been combined into one gain setting where rockbox selects a combination that's the best for you. Gives you as much analog gain as possible with the 0.5 dB step of digital gain. (c) Mmmm

ADC gain was a wrong description anyway...

[udo]

About the clip protection:
How smooth is the gain reduction?
I.e.: does it draw attention?
Or is it safe to use? Can it be influenced enough? (not afraid to compile my own version if necessary)

Some clip protection if e.g. signal reaches -3dBFS would be nice. Some type of limiter-like stuff?

There is lots of technical info in THIS THREAD about AGC and all it's various settings.

[Mmmm]

A possible new addition to the REP.

Pressing the record button with this patch will start up a new file continuing seamlessly from the previous one (so you can add track splits in real time). I've moved the pause function to the play key (which I was always pressing when i wanted it to pause anyway! )

Try it out, tell me what's wrong with it and all the usual stuff...

Only implemented for irivers at the mo....not sure about the buttons to use on other targets but would be very easy to put in. Any suggestions?

The other targets with recording are the Ondio and Gmini100 I think. It would be ideal if we could have the present recording button as the Record/new file button and another button as pause. But which button on these would be good for pause? Is there a spare button at all on those targets?

Anyway...heres the present patch for the Irivers:
manualrecordingsplit.patch

[Mmmm]

Ok, post#1 has an updated patch and build.

I've also added my latest patch (realtime tracksplit) see post#1 for details.

So Mlind, there you go...

Withe the latest patch I get this error:

Invalid operands to binary * in line 1531 which reads:

peak_meter_screen(&screens, 0, pm_y + h*filename_offset, pm_h);
