How To Prevent Hum When Recording Spoken Voice

Hi,
I'm recording some audio files with mostly spoken voice but when listening to playback there is hum.
I'm using a USB Logitech headset/mic (pretty new, the one with the volume control on the cable). The level is set to half.
I'm also using Motu Firewire 828 Mark II as part of my studio set-up.
So in Logic Pro Preferences - Audio I set the device to Logitech Headset, then do my voice over recording which sounds fine balance wise in the head set.
When I change the device back to Motu 828 in the preferences and play the recording back over my speaker system, there is hum behind the voice.
Can anybody tell me how to get rid of this hum?
Any advice will be much appreciated.

And if you play it back over the headset, there is no hum? What is the resolution of the Logitech? 16 bits 32 kHz? 16/44,1? 16/48?
Can anybody tell me how to get rid of this hum?
IF it is in the recording already, yes:
It is probably a 50 or 60 Hz hum.
You need to apply strong, narrow eq. Insert a *Channel EQ* and start with finding the base frequency. Pull the filter down and sweep the frequencies between 0 and 200 to find the base hum, then set it up something like this:

How to prevent MIGO when source inspection lot is either open or rejected.

Hi
How to prevent doiMIGO when source inspection lot for the vendor/material is open or the source inspection lot is rejected.

Hi Sudhar,
Please find the process steps for your question :
How to prevent MIGO when source inspection lot is rejected
Go to Q-info record (QI02) for that particular material, vendor and Plant combination.
1.Use Inspection Type 0130 for source inspection.
2.Number of days ahead of lot to be created.
3.Through transaction code QI07 run the manual program to create a lot.This source Inspection may be rejected as in your case.
4.Control key contains the control on GR in the QM view of MM.
In the spro>QM>QM in Procurement-->Define Control Key and assign it to MM.
We can define here under Source Inspection Control that in case of GR for rejection-->GR not allowed.
This will prevent MIGO if in case Source Inspection Lot is rejected.
Thanks,
Ravi.

SAP HR: How to prevent delimiting of records when setting a lock

Hi All,
I am part of a SAP HR implementation. In one of the Infotypes, I am copying a record and setting a lock in the new record by going to the menu Edit-->Lock/Unlock.
This should ideally lock the record without touching the previous record. But in my case, the previous record is being delimited. Can someone tell me what settings need to be done in order to prevent the delimiting of the previous record till the lock is unlocked.
Thanks & Regards,
Shobhit

I think it depends on the Time Constraint of the Infotype in question. Do you have a valid record with a BEGDA after the record that you are trying to lock?

How to prevent summation of records in bex based on keyfigure

Hi All,
I am getting records from Cube as below.
EMP1 24/1/2015 7 -- Request 1
EMP1 24/1/2015 6 -- Request 2
So When i display in bex report. I want to display as individual records instead of summation. How can I achieve it.
Regards,
Raj

There are four approaches.
Enhance existing cube with new characteristics and maintain unique number (for this we may need routine by updating current 0REQUID number) while loading data. we can access 0REQUID number in start routine. even if you compress the cube still we can see different records.
Add new infoobject and through virtual characteristics add unique number it will not summarize.
Create new infoobject let call ZUNIQUE update ZUNIQUE withe numbers like 1001, 1002 upto based on count of records in existing cube. and add ZUNIQUE infoobject to existing cube and create multiprovider with these infocube and infoobjecgt ZUNIQUE identify both objects since mutliprovider is union it will bring the data from both values ZUNIQUE from cube(no values in cube) as well as infoobject (we maintained numbers) in this case data wont be aggregate. let try this
Final options should not compress the cube

How to prevent duplicates when syncing

Whenever I sync anything to my iPad, iPhone I constantly get duplicated. This includes contacts, tasks & notebooks. How can I prevent this from happening?

If you have an email account that syncs over the air, you can get duplicates when syncing if you have these selections checked to sync with iTunes. Go to the Info Tab in iTunes when the device is connected to your computer and you are ready to sync - and look at what you have checked to sync. Look at Contacts, Calendars,and Other.

Low pitch hum when recording audio with iOS 7.1.2

I recently updated my ipad OS and now when I record I get a low pitch hum. I have checked all of my cables and connections, I've tried out different pre-amps (alesis iodock and focusrite scarlett 18i8) and I can not get rid of the hum... When I hook the pre-amps up to my pc the sound is crystal clear. Any suggestions? I've tried looking for firmware updates but none are posted as of yet.

How to prevent email when using find my iphone

Hi there,
Am I the only that finds the email confirmations annoying when using find my iPhone?
Is there any way to prevent these emails, or a preference somewhere to turn them off?

Apple:
Considering the threads here and on other Internet sites, this is clearly a safety issue. As a parent who uses this feature on my children's phone - this feature should be optional. Notifying the bad guy when you are searching for your phone/child is not an option. Thank you.

How to Prevent the Duplicate record insertion by JDBC Receiver?

HI Experts,
I have File Sender to JDBC Receiver scenario.I am using SAP PI 7.1 system.
Purpose of this Scenario is to read the data from specified file and INSERT or UPDATE the same records in Oracle Database.
Before inserting the data I want to check in the same table for prventing runtime error(Key fields Duplicatin).
So if records with the same key fields are available in table then I want to UPDATE the same record instead of INSERT.
Please Suggest me the poosbile way.
Thanks & Regards
Jagesh

Hi Jagdesh,
The JDBC receiver format has the following structure
<root>
<StatementName1>
<dbTableName action=u201DUPDATEu201D | u201CUPDATE_INSERTu201D>
<table>Table1</table>
<access>
<col1>val1</col1>
<col2>val2new</col2>
</access>
<key>
<col2>val2old</col2>
<col4>val4</col4>
</key>
This structure creates a query in this way :
UPDATE( OR UPDATE_INSERT) into Table1 set col1=val1 and col2 = val2new WHERE col2=val2old and col4=val4.
The key field works like a Where clause. So for the receiver format when you specify the key, it checks the DB with that field as the where criteria. Hence for a UPDATE_INSERT query, when you specify the key field, it checks whether that value specified within the key field exists in the DB or not. Then it proceeds to execute the statement for only those values.
Hence it makes sense to provide a primary key attribute in the key field of the JDBC receiver format.

How to prevent this: When I have an RDP connection to server and it is idle then I come back to it, it looks like I got kicked out but I'm not

Hi,
I have this situation: Say that I am RDP to a Windows server 2008 at least. I noticed that when I have an RDP session and I stopped working (idle) but still logged in, then I come back to it, the RDP session goes away as if I just got kicked out.
However, when I logged in again, I'm back to my session.
I looked at my GPO and I don't have anything set that relates to Terminal Session.
What is it and how do I fix this so I don't get kicked out?

Yes, set it to 1. You do not want to set it to 15 minutes or longer because that will most likely not fix the issue you are seeing. NAT Firewall timeouts are the most frequent cause of this issue,
and they are often set to 10-15-20 minutes by default.
I forget exactly, but I think in practice it will actually be 5 minute intervals when it is set to 1. The reason I said what I did is I didn't want to tell you it means minutes (which is what it means) and then you test it and realize that it is not
sending the keep alives at 1 minute intervals. If I remember correctly you can get lower by setting it to other intervals, for example, setting it to 2 would actually be more frequent than setting it to 1, but because I have noticed it stop working when
using the other intervals I recommend you set it to 1, which is the default.
Additionally, the exact behavior of the keep-alive may vary depending on the precise version, service pack, hotfixes that you are running.
The above is the longer explanation. Again I recommend you enable it and leave it at default of 1 and make sure to restart your server so the change takes effect.

Can you 'pause' when recording a voice-over?

We are wanting to put a voice-over on a Keynote presentation. We would like to be able to 'pause' the recording as we move through the process ... it's at least an hour long presentation (it was originally 3 hours, now being cut down).
Once it's done, we want to export out the whole as a ProRes LT Quicktime movie.
So that's the question, can we pause the audio recording, and have the end result exported Quicktime with a smooth timing (no pauses)?
All ears,
B

You're an ace Gary, thank you most kindly.
This system works beautifully, so beautifully that she went back and rebuilt the first show in HD (I think it was previously some odd format like 720 x 540). And the show looks great now on a standard LCD screen.
She'll love the 'pause'.
All the best,
Ben

How to prevent inserting a record in @SecondaryTable

Hello,
I have a table
USER:
-USER_ID
-USERNAME
-PASSWORD
and view that is not updatable
USER_STATISTICS:
-USER_ID
-TOTAL_RATING
-OWNED_ENTITIES_COUNT
I used @SecondaryTable annotation to get all data for a User in one class.
{color:#339966}@SecondaryTable(name="USER_STATISTICS", pkJoinColumns={@PrimaryKeyJoinColumn(name="USER_ID",referencedColumnName="USER_ID")})
public class User
{}{color}
What I want is - to save data only in USER table. I tried to set insertable=false, updatable=false to totalRating and ownedEntitiesCount, but it is impossible to do this for USER_ID in USER_STATISTICS.
Is it possible to do what I want with @SecondaryTable approach? How I can do it in different way? Thank you very much.

How to Prevent Workflow when Automatic PO created in 3rd Party Sales

Hello,
We have set up a special Sales Document Type for the purpose of 3rd party sales. The item category is TAS, so the Purchase requisition gets created automatically.
The problem is that when the Sales Order is saved, it starts a Business Workflow and sends an email to our EDI Technical Team. We want to disable the workflow functionality in this sales document because it is not needed.
Is there a way to disable ALE for a sales document type?
Thanks very much!

Hi,
Please review the following notes for more information:
550388 FAQ: Customizing of third-party and individual Pos
210997 Accnt assignmt categoriesin third-party and indiv.P
On creating Purchase order for requirement created for a customer sales order stock, if the customer sales order stock is not valuated, this means a Consumption ( GBB ) account is involved here. If the posting is a consumption account, SAP allows the user to decide whether it should be autotmatically or manually entered. Because of this option, system need this account to be set with Field 'Automatic posting only' to ' '.
With this field 'Automatic posting only' setting to ' ', whether the account can be automatically or manually entered is then controlled by the field status in the PO creation. If you do not want the user to enter the account manually, then this account should be set to display mode in PO.
If the customer sales order stock is valuated, then in General business process, this would involve a BSX ( material account )
postings. Normally this is automatically derived during PO creations. No manual enterring is allowed. Thus if it is correct to set this account with field Automatic posting only' setting to 'X' in FI settings.
Please read the note 37563.
Please check if note 842977 is present in your system.

Re: How to prevent shutdown when closing Satellite A35-S159 lid?

I just inherited a Toshiba Satellite A35-s159.I am running XP.
When I shut the lid,Windows shuts down.
I would like to keep things on, to be able to recieve updates and downloads.
I don't see anything in the "control panel" to allow me to do this.
In the control panel there is "Toshiba Power Settings" but I don't seem to be able to find a way to change a setting in there to keep everything running with the lid closed.
I see a prong on the screen lid that contacts a switch when it is closed,which then shuts the computer down.
Has anyone take to grinding this prong off? Is that the only solution?

Hi there!
I wish I was able to use the "Power Management" in my OS!
In "Control Panel" I have "Power Management"...but when I click on it,I get a message telling me to use the "Toshiba Power Management" which is a seperate icon in the "Control Panel".When I click on the OS "Power Management" I am not able to make any choices,although I can see them as gray ghosts in the background.The choices would seem to be more extensive. The "Toshiba Power Management choices are few and seem rudimentry in comparison.
I am guessing that Toshiba customized the Control Panel to be computer specific for the A35 model?
I am wondering if I have any choice but to disable the lid switch.That may have been Toshiba's idiot proof way of power management at the time.

How to prevent a new record sequence number to be created for a period of 14 days

ALTER proc [dbo].[spCreateSequenceContainerFill]
(@containerID as nvarchar(64),
@lotNum as bigint,
@customerID as int = 1164,
@productID as int,
@fillDateTime as datetime
as
BEGIN
declare @checkcontainerID as bigint
DECLARE @ID int;
set nocount on
SELECT @checkcontainerID = CONVERT(bigint, SUBSTRING(@containerID, 1, 6)) FROM ContainerFillHistory WHERE containerID = @containerID
IF (@checkcontainerID is null)
SELECT @ID = COALESCE((SELECT MAX(ID) + 1 FROM ContainerFillHistory), 1)
ELSE
SELECT @ID = Max(ID) FROM ContainerFillHistory WHERE containerID = @containerID AND @fillDateTime >= DATEADD(DAY, 14, CAST(fillDateTime as DATETIME))
IF (@ID is not null)
SET @ID = @ID + 1
INSERT INTO ContainerFillHistory(ID, containerID, lotID, customerID, productID, fillDateTime, purchorderNum)
VALUES(@ID, @containerID, @lotNum, @customerID, @productID, @fillDateTime, null)
END
If there is a no record with an ID then a new record is created and inserted in the table. After 14 days it is OK to add another record with that ID and bump up the sequence number of the total records in the table. Handling the non existing
case the first time is OK, but the restriction of 14 days if a new record is trying to be inserted has to be ignored.
So far I have this TSQL code.

Please try the following and tweak accordingly.
ALTER proc [dbo].[spCreateSequenceContainerFill]
(@containerID as nvarchar(64),
@lotNum as bigint,
@customerID as int = 1164,
@productID as int,
@fillDateTime as datetime
AS
BEGIN
SET NOCOUNT ON;
DECLARE @ID int;
IF EXISTS (select * FROM ContainerFillHistory WHERE containerID = @containerID)
BEGIN
SELECT @fillDateTime = DATEADD(DAY, -14, @fillDateTime)
IF EXISTS ( SELECT *
FROM ContainerFillHistory
WHERE containerID = @containerID
AND CAST(fillDateTime as DATETIME) > @fillDateTime --AND @fillDateTime >= DATEADD(DAY, 14, CAST(fillDateTime as DATETIME))
BEGIN
RETURN; --//14 Days condition not met
END
ELSE
BEGIN
SELECT @ID = Max(ID) FROM ContainerFillHistory
WHERE containerID = @containerID
AND CAST(fillDateTime as DATETIME) <= @fillDateTime
END
END
ELSE
BEGIN
SELECT @ID = MAX(ID) FROM ContainerFillHistory ;
END
IF @ID IS NULL
BEGIN
SET @ID = 1 ;
END
ELSE
BEGIN
SET @ID = @ID + 1 ;
END
INSERT INTO ContainerFillHistory(ID, containerID, lotID, customerID, productID, fillDateTime, purchorderNum)
VALUES(@ID, @containerID, @lotNum, @customerID, @productID, @fillDateTime, null) ;
END
