Recording Enhancements Pack

[Mmmm]

I've been doing some testing with the PCM buffer display and with svn there is a slight 'twitch' every 5 seconds or so to 8000 and then fairly quickly back to 0....
With the REP installed this happens every 0.5 seconds or so....

I have been experimenting with yields in various places and I now have it so that there isn't even the suggestion of a twitch at all, and that's with REP installed! So better than SVN it seems!

Only testing will tell if this fixes the problem, so any testers out there please give the build in my sig a go (H120/140)... I'll do an H3xx build later (got to rush off to dinner now!)

EDIT: H3xx build HERE

Well, peturs lastest bringing of something to my attention has shown that some atomicity issues in the scheduler must be fixed and fast. The cliplight may very well increase the likelyhood of a thread to get orphaned or not scheduled properly due to posts from IRQ handlers -- increased backlight activity and all that. The problem will be worse on targets with fading in combination with cliplight. It caused thread orphaning not just in recording but playback and other places. It's not likely, but a large number of copies of rockbox running will make it a situation someone is sure to encounter regularly. A change I made earlier made it less likely but hardly impossible...time for a thorough scheduler scan and bugfix.

The report petur pointed me to is a dead ringer for such an occurrence. The timing changes from this patch are probably relevant to the race condition.

I've updated the patch in post#1 to latest SVN and put in the yields that improve the buffer usage. So hopefully that and JSMikes updates mean the problems that have been seen recently are no more....

I should have the proper code guarding in the scheduler/queues in SVN today or tomorrow. I think it'll be a red line on the delta table but it's a decent solution with more detailed panicf as well. Really, I want to take my core lock patch and commit it sans locking but I fear it still might bork the PP5020 targets since all the IRQ fiddling seem to be what keeps them running. Without the locking mechanism in place it will basically be a rework to keep IRQs completely away from the scheduler which is really the _right_ thing imo.

I have asked this in another forum but didn't get a good answer.  Here's the question.

I am looking to record some short films and am looking at using my H320 to record field audio.  Is there a "pretty" and more useful recording interface?  Something with much larger text and metering that anyone has come up with?  I was pointed to this branch of the forums by a few others who thought you guys would know best.

The recording in 44.2KHz audio isn't the best answer for video (it's 48KHz) but it will do with conversion so that's all cool and since it's hard coded, it'll do.  As I am getting older, the tiny little meters built in to the current build RockBox are just too tiny to be usable for a real audio operator under stressful situations on a film shoot.

Anyone have an easy to install option?  I would do the programming for it myself if I had the time but I simply don't.  IF anyone has ideas or even better, screen shots of various record screens, that would help a lot.  Otherwise I'll breakdown and buy an H4 or the new H2 for these projects and keep the H320 as a media player.  I love it for that.

Thanks folks,

The REP (the thread you're posting in now) has such a feature but you'd probably have to disable some other visual stuff to make room. Others should be able to help you on that (I'm not a REP user)

I think the h3x0 (and h1x0) series can't handle 48kHz. You could try to get an h1x0 and use its optical input. IMHO I don't think the quality difference between 44/48kHz is significant.

I just noticed the static user-selected recording directory patch over here...

Will this be included in the REP? If someone would provide me with a patched build I'll test it and report back here.

As a newbie with a 120, what steps should i take and what should i install from the beginning, i am a little confused about all these downloads, patches, enhancements, is there one download that covers it all? everyone says get the REP but not sure where to begin. i am going to be using the 120 to record live shows?

Thanks

Download the build in Mmmm's signature. You can follow the standard install instructions:

Good luck - enjoy.

As you can see on that tracker-task, there's still a bit of discussion going on about what we want it to do. I'm quite sure it's supposed to be included in the svn version.

I've run Mmmm's 05-11 build a bunch of times, so far, with no problems. I'm trying the 05-13 build today on an iHP-120 and an iHP-140.

[davehouse]

how can i tell what version of the H120 Rockbox firmware Im running, and whether Mmmms latest build is a newer version? I downloaded Mmmms build with the REP ages ago and recon its probably time for an upgrade. But I dont wanna do that if I dont need to!

[TaperChuck]

No problems running the lastest Mmmm build on iHP-120 and iHP-140 last night.

Hey Mmmm,

A few months ago, i installed your build with the REP on my H120, and it works great, but today, i just bought a refurbished H115, and i was wondering if i will be able to just install this same build on it.

From what i understand there are some few minor differences in the ram (smaller buffer) but besides that, not much difference, should it be okay?

If not, what will i need to change in your build to make it so it works the same as my H120. I would like them to have the same build and what not so when i am recording with both at shows, i can get my levels to match and stuff like that.

thanks a bunch!

Is the version of the rec-button-config used in the pack the most recent one? right now the REP does not compile with the latest SVN. It breaks on an error when compiling the additional rec-button-patch files

EDIT: was a simple fix really.. so never mind..
