Trying to Get the "Difference" Between Two Tracks

What I am trying to accomplish is this: I have an audio track of a voiceover with a music bed beneath it. I also have the bed music by itsself, without the voiceover. I want only the voice portion. Is there a way that I can "cancel out" the music portion or get the difference between the two tracks (just the voice portion)? It seems that there should be some means of doing this, but for the life of me I cannot figure out how to do it!
Any advice?

If it's exactly the same music track, then as long as you line it up sample-accurate and the levels co-incide, you can do a simple subtractive process. You need both files available, trimmed to length. Open them both in Edit View, and copy one of them to the clipboard. Open the other, and select Mix-paste, and use the 'invert' option. That will effectively subtract one from the other, with the difference being your vocal.
Have to tell you though that the chances of getting this spot on are amazingly low... any errors at all leave you with bleed-through, about which you can do nothing.

How to get the difference between two columns in a column group

Hi All,
My first time here and really new to programming. I would like to get the difference between 2 columns that are inside
a column group.
Here is my sample table below: The Column Group is PeriodNumber and can only choose 2. like 1 and 2.. I would like to have a third row which will simply calculate the difference between the amounts in PeriodNumber 1 and 2.
PeriodNumber
Account 1 2
1) Cash 10,000 15,000
2) Receivables 12,000 11,500
3) Equipment 5,000 5,500
Total Assets 27,000 32,000

Hi yabgestopa,
From your description, you want to get the difference between two columns in a column group. After testing it in my environment, we can use custom code to achieve your requirement. For more details, you can refer to the following steps:
Copy the custom code below and paste it to your report. (Right-click report>Report Properties>Code)
Dim Shared Num1 As Integer
Dim shared Num2 As Integer
Public Function GetAmount(Amount as Integer, Type as String)
If Type = "1" Then
Num1=Amount
Else
Num2=Amount
End If
Return Amount
End Function
Public Function GetDif()
Return Num1-Num2
End function
Right-click the second column to insert a third column with Outside Group-Right.
Then use the expressions below in the matrix.
=Code.GetAmount(Fields!Amount.Value,Fields!PeriodNumber.Value)
=code.GetAmount(Sum(Fields!Amount.Value),Fields!PeriodNumber.Value)
=Code.GetDif()
The report looks like below.
If you have any questions, please feel free to ask.
Thanks,

is there a way to know the difference in days between those two dates ?
Thanks

hi,
try this.....
DateFormat formatter = new SimpleDateFormat("E MMM dd HH:mm:ss Z yyyy");
Date date = (Date)formatter.parse(dateStr); //// dateStr <- from date value (that is string value)

How to get the difference between two HashMaps

i have two HashMaps
HashMap first = new HashMap<Integer,Object>();
HashMap second = new HashMap<Integer,Object>();
How to get the difference between one and two and put the result in the third
HashMap third = new HashMap<Integer,Object>();

My bad, difference of course means removeAll():Map<Integer,Object> first = new HashMap<Integer,Object>();

Map<Integer,Object> third = new HashMap<Integer, Object>(first);
third.keySet().removeAll(second.keySet());No loops needed.

Function Module to get the difference between two times.

Hi All,
I want to know if there is any function module that gives me the difference between two specified times.
For Ex: Time 1: 12/01/2007 00:01 A.M
            Time 2: Time 1 - 180 Seconds. This changes the time, also may even change the Date. (As in above situation, the Time 2 will be 11/30/2007 11:58 P.M)
Could some one please suggest if there is any function module for this case.
Thanks in Advance.

Hi, You can use the following function module to calculate the diffrence between to dates in the unit that you want.
COPF_DETERMINE_DURATION calculates the difference between two dates and time in minutes and hours.
Parameters:
EXPORTING
     I_START_DATE "The start date of the time interval
     I_START_TIME "The start time of the time interval
     I_END_DATE   "The end date of the time interval
     I_END_TIME   "The end time of the time interval
     I_UNIT_OF_DURATION "Time unit of the duration if not to be calculated in days.
     Value     =====     Meaning
     ' '     =====     Day (default)
     D     =====     Days
     H     =====     Hours
     MIN     =====     Minutes
     MON     =====     Months
     S     =====     Seconds
     WK     =====     Weeks
     YR     =====     Years

Need to get the difference between two period

Hi All,
I need to get the difference of two posting period like period is in format YYYYMM.
I need to subtract posting perid '200512' FROM '200601' how will be it possible.
Please suggest.

Hi,
YOu can also do like the following.
Determine you first day of first period and last day of second period.
data: first_day type datum,
      last_day type datum,
      days type i.
first_day = date from FM RKE_GET_FIRST_DAY_IN_PERIOD
last_day = date from FM RKE_GET_LAST_DAY_IN_PERIOD
days = last_day-first_day.

How to get the difference between two BufferedImages?

All the BufferedImage which is grabbed from AWT may be same each other,
i only want to get the different part of two continuous BufferedImages and send ti over internet.
I have compared two BufferedImages by RGB (int[]), but this process wastes 400~500ms,it's terrible,:)
who has any good idea about this?
thanks
Best Wishes
mauvespan

thanks ! cary ,
I have a list contained some BufferedImages gotten from AWT component,and then these images
will be transfered to client and displayed in Internet explore ,actually there are only some difference
between two continuous BufferedImages,i don't want to transfer the WHOLE image to client,SO i
want to handler every image before sending to client , at last, the different part will only be sent to client.
All these ideas will be contained this method:
* Compare the specified two BufferedImages and return the different part between them.
* @param ref the specified first image
* @param gen the specified sencond image
* @return the different part between the specified two images.
public static void BufferedImage compareBufferedImage(BufferedImage ref,BufferedImage gen){
to finish this method ,do you have any good ideas?or sample code?

Need a sql query to get the difference between two timestamp in the format of hh:mm:ss.msec

I have a database table where it keeps record of the transaction when it starts at StartTime and when it ends at EndTime. Both these entries are having the timestamp entries. Say for example, I have a tuple with Entries like 'Transaction A' starts at '2014-05-07
20:55:03.170' and ends at '2014-05-08 08:56:03.170'. I need to find the difference between these two timestamps and my expected output is 12:01:00.000. Let me know how to achieve this ?

Hi,
You can use below script which calculates difference as DD:HH:MM:SS. You can modify the same:
DECLARE @startTime DATETIME
DECLARE @endTime DATETIME
SET @startTime = '2013-11-05 12:20:35'
SET @endTime = '2013-11-10 01:22:30'
SELECT [DD:HH:MM:SS] =
CAST((DATEDIFF(HOUR, @startTime, @endTime) / 24) AS VARCHAR)
+ ':' +
CAST((DATEDIFF(HOUR, @startTime, @endTime) % 24) AS VARCHAR)
+ ':' +
CASE WHEN DATEPART(SECOND, @endTime) >= DATEPART(SECOND, @startTime)
THEN CAST((DATEDIFF(MINUTE, @startTime, @endTime) % 60) AS VARCHAR)
ELSE
CAST((DATEDIFF(MINUTE, DATEADD(MINUTE, -1, @endTime), @endTime) % 60)
AS VARCHAR)
END
+ ':' + CAST((DATEDIFF(SECOND, @startTime, @endTime) % 60) AS VARCHAR),
[StringFormat] =
CAST((DATEDIFF(HOUR , @startTime, @endTime) / 24) AS VARCHAR) +
' Days ' +
CAST((DATEDIFF(HOUR , @startTime, @endTime) % 24) AS VARCHAR) +
' Hours ' +
CASE WHEN DATEPART(SECOND, @endTime) >= DATEPART(SECOND, @startTime)
THEN CAST((DATEDIFF(MINUTE, @startTime, @endTime) % 60) AS VARCHAR)
ELSE
CAST((DATEDIFF(MINUTE, DATEADD(MINUTE, -1, @endTime), @endTime) % 60)
AS VARCHAR)
END +
' Minutes ' +
CAST((DATEDIFF(SECOND, @startTime, @endTime) % 60) AS VARCHAR) +

Get the difference between two java.sql.Time values

Hi, I'm developping a web application in which I need to to subtract one java.sql,Time value from another. The two values are stored in a database field of type DateTime. I used following code
java.sql.Time start_time=resultset.getTime("startTime");
java.sql.Time end_time=resultset.getTime("startTime");
java.sql.Time diff=start_time-end_time;
can u give me any comment on this code

Remember what the Date/Time object in Java represents - a single point in time.
Subtracting one from another gives you an amount of time elapsed between the two dates. Fine.
Making a new Date out of that number is incorrect. The number no longer represents a point in time, but rather a duration.
Its like saying "There is 10 seconds difference between the two times, so the time is now 1 Jan 1970, 00:00:10 GMT".
The simple and stupid calculation is to take the milliseconds difference, and divide it to get to a more humanly readable value.
// duration in milliseconds
long duration = ?????
long durationInSeconds = duration / 1000;
long durationInMinutes = duration / (60 * 1000);
long durationInHours = duration / (60 * 60 * 1000);
// careful - not always true!
long durationInDays = duration / (24 * 60 * 60 * 1000);
NOTE: The "daysBetween" calculation is potentially complicated by Daylight Time adjustments. The simple approach does not necessarily work exactly.

How to get the difference between two dates???

HI I have two dates and I want to test if there is an hour between them.
Is there a way to compare two dates like mySQL can with dateDiff(date1,date2);
Thanks alot.
Graham

This link is now out of date as they have revamped the structure. Yep. Here it is again: http://forum.java.sun.com/thread.jsp?forum=31&thread=502686
I've also noticed that my comment regarding daylight saving was misleading. The demonstrated method for calculating difference between Dates is reliable. However, one needs to be careful when interpreting Dates in a daylight saving timezone.

Trying to find the difference between two sub-totals (sales - credits)

Hi Everyone,
I have the following code which essentially lists the total sales for an items on the first row, and the total credits for the same item on the second row.
SELECT T0.ItemCode, SUM(T0.LineTotal) as 'Total Sales'
FROM INV1 T0
WHERE T0.ItemCode = 'ACR2401010'
GROUP BY T0.ItemCode
UNION ALL
SELECT T1.ItemCode, SUM(T1.LineTotal) as 'Total Sales'
FROM RIN1 T1
WHERE T1.ItemCode = 'ACR2401010'
GROUP BY T1.ItemCode
The results of the query are shown below (with some alterations for confidentiality).
What I would like to do is write a code block that subtracts the total credits from the total sales, leaving me with only one row of data for the ItemCode.
If anybody can help with writing the code to achieve this it will be greatly appreciated.
Kind Regards,
Davo

Find the difference between two internal table

how can i see the difference between two interal tables?
The requirement is as follows
1. We have a transparent table, which stores the employee data with EMP ID as key.
2. We load the transp table data into a interal table (B).
3. We get data from legecy system as file and it gets loaded into another internal table (A) (this also has the same EMP ID key and this will have latest addition/update to those emplyees).
Now we need to seperate out these data into three interal table Inserted (I), Deleted (D) and Updated (U).
We want to do followign things
I = A - B
D = B - A
Both A and B will have around 40k records. Hence we are trying to avoid the looping.
Please suggest the best option for us.
Thank you in advance.

Hi Raghavendra,
Currently as of my knowledge, these operations are only possible through LOOPs. But LOOPign can be really fast here if you properly utilize the SORTING, READ with BINARY SEARCH and FIELD-SYMBOLS usage. I would say:-
Steps for Insert:-
SORT: A, B.
LOOP AT A ASSIGNING <WA_A>.
READ TABLE B WITH TABLE KEY key = <WA_A>-key BINARY SEARCH.
IF SY-SUBRC NE 0.
APPEND <WA_A> TO I.
ENDIF.
ENDLOOP.
Steps for Delete:-
SORT: A, B.
LOOP AT B ASSIGNING <WA_B>.
READ TABLE A WITH TABLE KEY key = <WA_B>-key BINARY SEARCH.
IF SY-SUBRC NE 0.
APPEND <WA_B> TO D.
ENDIF.
ENDLOOP.
Regards,
Ravi.
