Automatic Level Control.

I am transferring stereo audio cassettes into GB. I noticed that when I check Automatic Level Control, it always goes to 75%. Does this just start there and manually ride the audio or is it "smarter" in a digital way. I think the results with the auto level "on" sound good so far but I noticed a few sudden volume drops here and there. I am not sure if they came from the Auto Level. It's hard to find the exact spots on tape to compare since I've transferred a few hours worth already. Do I need to go back and just set my own levels? I do want to best possible copy. If so, can let it hit red on the peaks? (I don't hear it distort on the short peaks but I'm monitoring with crummy speakers now) Thanks!

In case anyone is curious, the Auto Level is not for quality recording. It was jumping the volume around after all. Be careful of this. That's how you learn a new program I guess I wanted to redo some other stuff anyway so no big loss.

Automatic Level Control is dimmed. how do I activate it?

I noticed right under the menu that has the track effects on the right side, that the Automatic Level Control is dimmed. How do I activate it?

Recording Level Automatic Level Control

My ALC setting has changed. It used to be OK but now the check box is unchecked for every recording and the slider is maxed out! from the start My recordings are really too loud! How can I reset GB so that the ALC is on by default as it used to be? I don't know why the setting changed. Please let me know if I should just reinstall GB or what I can do to reset the ALC to "on" as default.
Thanks.
DF.

I refer the honourable gentleman to the reply I gave some moments ago.

Auto level control working even though unchecked?

Greetings,
One of my singers is cutting tracks for me using GB 6.0.5. He has the Automatic Level Control checkbox unchecked, but says that the volume slider is still moving all over the place as he sings. Any idea what could be causing this?
Thanks,
DM

That slider should indeed only move with " Automatic Level Control" enabled; perhaps the preferences file is corrupted. Try HangTime's cure for "Oddball" problems and remove the GarageBand preferences and repair permissions:

P.S.
Are you using Mac OS X Lion or later? Then your user library is hidden. You open it best from the Finder's "Go" menu, from the main menu bar:
Go > Go to folder then hold down the alt/option key until the library appears in the drop down menu. Select it to open.

Automate Process Control to update Review Levels

Using 11.1.2.2.301
Is there a process that can automatically start and promote new members to a specific review level, or the review level that its siblings are currently set to?
Back ground: At the beginning of each period we manually promote all entities to Review Level 1 which allows our data load automation and consolidation to work as expected. As we work toward closing the period new members are added to the metadata. Since these are not at the same review level our automation errors out. We need everything to be at the same level so the next group can promote on up to following review levels. We are currently using the filters in the Data Process Control section, but it is very manual and time consuming. Can automation be created to search through all the affected periods to find any member that is not at Review Level 1 and promote it to that level? If not automation is there a better way to accomplish this?
Thanks
Andie

Hi Andie
I know you can use Taskflows to automate Process Control actions so may be worth looking into that, but I have not used that option before so can't comment on how effective it is. Hopefully someone who reads this has a more elegant method of doing it!
In terms of finding which members aren't at RL1, it is pretty easy to knock up a report in FR or Smart View which can pull all entities at certain review levels, and you could use conditional formatting/supression options to filter out the ones which need promoting. You could run one of these prior to your loads just to make sure that everything is at the right review level and quickly pick up anything which isn't..
Thanks

Credit management automatic credit control use of credit group

Hello gurus
1)In the credit management we have credit groups( which enables us to combine different sales
document types for the purposes of credit management).
In the simple credit check also we will assign the doc types to check the credit. Then please tell me why we need credit groups in automatic credit control? Here also we can assign the doc types to check the credit ?then what exactly is the use of credit group ?
2)where will we specify the total credit amount allowed of the credit control area?
3)In the automatic credit control (ova8) against to static check box option we have open orders and open delivers checkboxes. is this two boxes only specific to static or it also belongs to dyanic?
Is it necessary to check this boxes?
4)is any one have used any of the routines in automatic credit control( document controlling tab we have no credit check field here we specify the routine? If any business need please share with me
Thank you in advance for all the replies

Hi
For your 1st query , In credit mgmt we assign credit grps to sales document type. So as you said we will assign credit grps at simple credit check and coming to the Automatic credit check we assign credit grp for the sales document type also .But the difference is credit grp can be at order level or Delivery Level or PGI level in OVA8 in Automatic credit check .
Coming to your 2nd Query , we will specify the total credit limit in FD32.
For your 3rd query , In OVA8 apart from the static check we check the boxes open orders and open deliveries also because once you activate Automatic credit check and once you maintain credit limit for any customer then system will check the open orders and open deliveries also of that customer
Coming to your last query the routine feild can be used when some requirements have to be fulfilled then only automatic credit check should work for customers. or else the sales order ->delivery->PGI will happen normally

Manual Audio Level Controls! - Sony Alpha DSLRS (A65)

Dear Sony -I absolutely love your DSLRs. However, to use the camera as an acceptable tool for amateur/indie/professional film, manual audio level controls in video mode are a must-have. Equal Canon competitors all feature this simple leveling option for managing audio.Currently, the automatic gain control is the only option for audio recording capabilities on Sony Alpha DSLRS in video recording. While in theory OK, AGC leads to terrible problems such as unnecessarily high and distracting background noise/hiss. Filmmakers desire crisp, clear audio!For quality results using an external microhpone, manual audio levels are the only way for filmmakers to achieve decent in-camera audio to compete with Canon users. Many amateur and professional videographers are in desperate need of this function! Audio is often MORE important than the image quality of your film, although Sony seems to increasingly neglect its video DSLR users by not implementing this ability and falling short on video options (Auto-focus in Manual Mode, audio levels on HUD etc.).To keep my Sony A65 a viable option for video work - please see if anything can be done! (Should be able to be added with a firmware update to all current and existing Alpha DSLRS) Thanks!!! - Love, a filmmaker who would desperately like to keep their A65 for professional video work! (Also from "Join The Inspiration")

Though a great idea, you also have to understand that the a65 isn't as film oriented camera like other cameras.
DSLR cameras with the audio controls are designed with film making in mind, thus they have that option.
Most DSLRs (at least, back in the days) was simply a camera to take photos. If you wanted to do film, you'd buy a dedicated film recorder for that. Having video capabilities in a DSLR was a bonus.
Nowadays, it's merging, bang for buck, reaching to a boarder audience, one size fits all, etc, and unfortunately, the a65 wasn't part of that 'nowadays' era.
The a99 and a77ii, if I remember correctly, has audio controls.
A lot of the newer Sony models (mirrorless) also have audio controls, that is, the ones that a targeted towards film making and not just great photos with the bonus of great video.
Also, I would presume that a lot of 'professional' videographers will either use external mics such as on a pole, a lapel mic, etc, to capture perfect audio, or if not, at least a shotgun/boom mic attached to the camera.
When doing such, there technically shouldn't be a lot of problems with the audio quality. Of course, if those external mics are still recorded into the camera, then yeah... but if they're recorded separately and slapped on during post processing... shouldn't be any problems...
If you're relying purely on the a65 and it's AGC, then there definitely will be shortcomings here and there unfortunately.
I recently filmed my niece-in-law's wedding. I didn't have any fancy mic setups (can't afford it at this stage), and this wasn't any sort of 'professional' work, more of just something for the family (free), but the audio came out excellent. Yes, it caught ambient noise (obviously), but I don't hear any cutoffs or badly pitched noises, or anything. The loud music and people cheering on and such all came through very clearly. Sure, it's no 'professional' bitrate or anything, but at 192kbps, it did the job.
Anyways, that was off topic, but all I'm saying is, you can't expect much from a photo taking centred camera which has been slapped on with nice video capabilities unfortunately. Also, due to the a65's age, I don't think Sony's bringing out anymore updates. My advice is either get an a77ii for it's awesome AF, or if full frame is a desire, then the a99 or a mirrorless (up to you).The a99 has a controllable focus range which is something I like, that way, if you're using autofocus (yeah... what 'professional' videographer would use autofocus aye?), you won't lose focus on subjects if something goes in front/behind it.Also, the little wheel at the front really helps in allowing you to make adjustments without disrupting video or causing too much movement in the camera. Right now, I am planning on getting a RX10ii. Though I'd love to get something from the mirrorless range, it's just way out of my budget (even the RX10ii is, so there's a lot of saving to do right now also...). Anyways, good luck with your videos.

Urgent: Need help in automatic credit control

Hi SD Seniors
Please help me in the URGENT Credit check Control Configuration.
According to the user requirement, need to have simple static credit control in the place of sales order & delivery.
When credit check fails during the order creation,
1.     Wants to popup the warning message without blocking the delivery
2.     And wants to block the delivery from the PGI process.
I have already done the necessary credit check configuration in my test system. Based on the simple credit limit check,
System issues the warning message correctly at the time of order creation.
And I have configured the automatic credit check control configuration for the blocking the delivery PGI steps. But system doesnt block
The delivery and it still allow proceeding for PGI without any error message.
Please refer by below automatic credit control check for blocking the delivery. Please let me know, is there any other step I missed out here.
1. Credit control area is assigned to the company code.
2. Credit control area is assigned to the sales area.
3. Credit control area is assigned to the payer.
5. OBZK:   Assigned
7. Risk category for each credit control area.
8. OVA8: -Credit control area + Risk category + Credit group
9. FD32: -Credit limit, Risk category, Currency: assigned
10. OVA7/VOV7: - Activated correctly
11. V/08: - Pricing Procedure subtotal set to A
12. OB45: - Update Group 00012
Your help is very much appreciated.
Thanks in advance
Regards
Priyan

Karan, Thanks For you Quick Response.
OVO8: Cr.Ctrl.Area + Rick.Catg + Credit.Group (03)
The same credit group was assigned to the OVAD also.
OVAD: Dely.credit.grp = 03   (Credit group for goods issue)
AND
GI.Credit.group = 03 (Credit group for goods issue)
Is it correct?
My doubt is where exactly, we are telling the system to block the delivery.
In OV08, could you please tell me what are all the settings need to be done for
block delivery PGI
Regards
Priyan

No zoom level controls on second monitor!

I use a second monitor to display a loupe view of the photo I have selected in the grid view, which is on the first monitor. I have always had the zoom-level controls (Fit, Fill, etc.) at the bottom of the loupe display on the second moitor, until I replaced my first monitor this week. Everything else is still the same, but I no longer have the zoom controls on the second monitor. This means that I cannot change the zoom levels that are availabel to me. I either have Fit or 100% zoom. Without the zoom controls on the second monitor I can't change the settings. Does anyone know how to get the zoom controls back (or why they might have disappeared)?
Thanks for any help.

Never mind. I found the problem (the second monitor was in full-screen mode). Nothing
to see here. Keep moving.

Automatic credit control

We use in our company automatic credit control. For one of our customers not credit control data have been maintened (fd32) therefore there is no credit group assigned to him.
When I try to make a sales order for this customer, the automatic credit control is turned on and I am unable to save the order since the next review data has passed (it is a check field in the automatic credit control for all customers that have credit control data).
Any opinions?

Hi,
If the customer concerned is not relevant for credit check,please remove the risk catigory under status screen in FD32

Level Control with PID Control & Pulse-Width Modulation

Hi all,
I have attached my program which I'm having trouble wiring up in the block diagram.... I'm fairly new to labview, but basically I have a level control project with an analog input cistern arm turning a pot for my test tank (configured as DAQ assistant voltage analog i/p) and a pump working off a reservoir (configured as DAQ assistant voltage digital o/p). My electrical side of things is working correctly and I have tested both DAQ assistants I/O's successfully off a basic program, minus the PID & PWM... I found a simple PID control subvi which I think I have wired up correctly, apart from the output variable... I also found a bit of code for PWM using the square waveform vi (far right side of the program) which I have tried to include in the program, but I've been unsuccessful with that. The ideal operation i'm looking for with this project is to be able to enter different values for the setpoint, for the PID to kick in to find that setpoint each time using the PWM to drive the pump, which has a flow rate of 13L/min. I have a manual valve to release water from my test tank which I can set accordingly.
My questions are;
- How do I connect the 'output variable' of the PID subvi to my DAQ assistant digital output(both DAQ assistants are set at 1 sample on demand)?
I have a 'number to boolean array' function, but this gives an error saying that the number of tasks generated are not the same...
- How do I wire up the PWM bit of code? Do I need to include the 'error in & out' tabs?
-Am I on the right track with this program or am I way off the mark?!
Any feedback on this would be greatly appreciated. Thanks for your time,
Richie

You're a bit off track. You need the output of the PID to go into the PWM generator, and the output of the PWM to be written to the digital output. Right now you have the output of the PID connected directly to the Digital Output in a way that won't work, and the PWM generator hanging off the side not really connected to anything. Also, the PWM generator isn't really going to work since you're generating it at the same frequency as your PID loop runs. Try a simpler algorithm such as on/off control first and see if that works for your system.

Tank Level Control with PID regulator

Hello!
I found a lot of examples regarding the simulation of a tank - level control with PID regulator. but I still have a dilemma.
I can't find the transfer function for the process, if you can help me it would be great because I'm stuck here...

Maybe you could ask some of you classmates?

Level control

Hi Everybody,
I am new to Labview so I am looking for your help. I am looking for the most basic control diagram for a PID level control circuit.Thanks.

Moonlight, at it's simplest, PID control works by operating on an error signal,or the difference between the desired output and the current output.
So, in order to implement PID control, the first step is to calculate that process error.
Second, you now need to multiply that process error by a proportional (P) constant, an integration term (I), and a differential term (D). Then add up those products.
There are MANY ways to do the integral and derivative terms, so I will leave that to you. Search for PID on the NI website, and you will find at least one example of how to do it.
Good luck,a nd I will repost later with some examples.

Overriding Processor audio level controls

Hello,
I'm developing an application to capture a live audio stream (by definition a PushDataSource). I want to provide my own controls for monitoring the audio (e.g. mute button, volume level control). What methods set the volume level? I didn't see any of this in the documentation.
I saw getGainControl, but I want to provide my own ... just setting the gain.
Is there an example of this?
Thanks,
Ben

brcain wrote:
Do I have to implement a GainEffect plug-in ... just to change the monitored audio level?No. You can actually implement the controls on the PushDataSource itself.
For instance, I have the following code available on the forum:
[http://forums.sun.com/thread.jspa?forumID=28&threadID=5342704]
That code will capture audio using JavaSound, and deliver it to JMF via a PushBufferStream. Because the capturing is done with JavaSound directly, I can run any kind of JavaSound processing I want on the audio before I hand it to JMF.
I could, for instance, convert it to ULAW before I give it to JMF...

I could, for instance, change the sample rate before I give it to JMF...

All you're handing to JMF is a set of audio samples. You can adjust them or monitor them however you want before you give them to JMF...

***AUTOMATIC FRAME CONTROLS

If you use a preset in Compressor, the frame controls are automatic for the most part.
Quick Question:
Should you manually turn off frame controls when working with progressive footage?
The reason I ask is because I already noticed in the quality of the footage and by running various tests that when you use one of the DVD presets for progressive video, the field dominance doesn't correctly change to progressive when you have it set on automatic, and I just don't want the automatic frame controls to do any automatic deinterlacing if it doesn't recognize the progressive attributes.
Thoughts?
Thank you.

I would set it manually or turn it off. If you want a progressive output, remember that you might also need to set the field order to Progressive under the Encoder tab under *Video Format* on your MPEG-2 (m2v) setting.
If you do not deinterlace with Compressor, a DVD-player or LCD-TV will do it anyway in real-time, which most likely will look pretty bad. Also be aware that the Apple DVD Player application does automatic de-interlacing.
As Apple writes in the Compressor User Manual:
*Automatic button:* When this button is selected, Compressor analyzes the transcoding job (the source media file and the applied setting), and then automatically determines the appropriate Frame Controls attributes. For more information, see About the Automatic Settings.
In Automatic mode, Frame Controls technology is engaged in the following two types of transcodes only:
• Transcoding from high definition (HD) sources to standard definition (SD) MPEG-2 output files
• Transcoding from interlaced sources to H.264 for DVD Studio Pro and H.264 for Apple Devices (progressive) output files
Automatic mode when encoding to SD MPEG-2 does not necessarily de-interlace. You can open your .m2v-file in e.g. MPEG Streamclip and hit "cmd+i" to view info about the file. There you can double check if your finished file is interlaced or not and what field order it is set to.
You can learn more about *Frame Controls* by reading this excerpt from Apple Pro Training Series: Compressor 3.5 Quick Reference Guide, by Brian Gary.
A really helpful tip, is to set an in- and out-point in your Preview window in Compressor to see test results quicker. Testing different settings on long clips is both unnecessary and boring. Select about 10 to 30-seconds from an area in your clip that shows variety in your video (both fast moving and normal scenes).
Video compression, especially for web and DVD, is all about testing to find the optimal settings for best possible quality/filesize ratio. Almost every video source is unique, and should be looked at and tested with different settings depending on both source quality and content.
Hope this helps

Automatic Level Control.
